Title: Copenhagen Suborbitals Updates and Testing
Post by: Voyager4DK on 05/19/2012 02:36 PM
Couldn't find any thread for Copenhagen Suborbitals (http://www.copenhagensuborbitals.com/), so desided to make a new one here.

They will have a big test of there new big Liquid propellant rocket engine TM65 (Tordenskjold) in 26Ż hours (sunday 19:00 local Danish time).
Read more about it here:

There is this old thread, about the previous launch campaign - but it might be better to make some sort of general thread, or possibly rename the old one.

I ment, I couldn't find any new thread, so made a new update thread..

Other newsworthy things:
They have started building a new spaceship called Tycho Deepspace with a LES rocket. The LES is going to be testfired with Tycho Deepspace this summer:

And Copenhagen Suborbitals Support (http://translate.google.dk/translate?hl=da&sl=auto&tl=en&u=http%3A%2F%2Fraketvenner.dk%2F) has grown to 606 paying members. Each member is paying 100 dkk ($17) each month (50 dkk for students). CSS is paying for materials, equipment and the work shop rent for CS, they are not paying for any salary as all work in CS and CSS in unpaid work. CSS has grown almost 100 members the last month, because CSS made a roadtrip arround Denmark to tell about CS.

TM65 reach about 50% of rated output, so there is still room for improvement in comming tests. And the engine should be able to handle 125%.

So what's happening on June, 22th with the clock ticking down on the website?

This summers launch campaign (http://www.copenhagensuborbitals.com/campaign2012.php) window wil open (June-Sep). And they have 5 launches planned this time.

The most exiting test is of course the Tycho Deep Space pad abort test:
Quote
Launch window: June-Sep, 2012
Test-range: ESD139, Baltic Sea
Trajectory estimates: apogee 1 km. downrange max 1 km.
Launch platform: Sputnik: 0-degree launch pad.
General info: Our new space capsule Tycho Deep Space will be launched using the LES-engine. Three main parachutes will provide us with a controlled capsule splash down at sea followed by recovery operation of Tycho Deep Space and the LES-engine.

Could you please give us a short summary about what is being said in this report, especially by Mr. von Bengtson?
Did he make any comments on the fact that the capsule came to rest upside down (I think for Apollo this was called "Stable 2"), and if they had a system installed that should right up the capsule?

Yes, that part of the test failed, they have 4 uprighthing bags as descripted here (http://www.wired.com/wiredscience/2012/06/diy-capsule-uprighting-bag-restraints/#more-114769). They didn't inflate fully, so the capsule didn't turn as it should. The guys think there must have been a short in the system somewhere. So they will repeate that part of the test locally at Copenhagen habor.
You can read more about the test here:

This report is from the local news, where they tell that the crane on Lindoe shipyard, is used to test the new capsule.

Mr. von Bengtson said that, he is glad they are able to use the crane for this test, because it is the only place in Denmark where they are able to do these tests. As the crane is so high (100m) it is able to do drops + there is water, make it a perfect place to test. All in all, he is happy with the tests, feels that they got the data they need, doing the day.

Another clip from the test

http://www.tv2fyn.dk/article/358626:Foelg-test-af-rumkapsel

There was a short circuit in the upright system, so 2 bags was not inflated all the way. But they will be able to do some more test back home in Copenhagen harbor.

This time we do not drop parachutes, we drop a capsule. We have our lates
version with us. It is outside and later we can all see it in details. Simply
said, it weight 450 kg,have a diameter of 2 m and the point of this test is
drop it with an angle, to see how it react when hitting the water. How it move
around in the water, what it's buoyancy capabilities are and how we can handle
it when it is in the water.

This week the launch platform Sputnik took the trip from Copenhagen to Nexoe,
where it will be, doing this summers tests. It took 26 hours to do the trip this
year, compared to last year 36 hours. Other than a minor oil leak from one of
the engine the trip was done without problems.

First test will be on 13.-15. July, if the weather allows it, where a 2 stage
rocket called SMARAGD will be launch. The rocket will be passive stable, with a
counter rotating top, outfitted with radio downlink to HDTV, GPS, accelerometers and gyroscopes as well as cameras and a parachute.

The first SMARAGD will have a 2. stage with only 20% fuel, the rest water. They expect it to reach 8 km. The second SMARAGD will have 100% fuel, and it is expect to reach 20 km, and will be launch 27.-29. July.

The main objective with these rockets is to test telemetry and radio downlink

Title: Re: Copenhagen Suborbitals
Post by: Morten C. on 06/30/2012 10:12 PM
There is talk about a °650mm HEAT size rocket, going high in 2013. Looks like it is going to be the TM65 engine.

This year they make experiment on the parts they think they need/be better at, learned from the 2012 launch of HEAT 1X - Tycho Brahe.

That is high altitude telemetry test (SMARAGD-1 and 2)
Active guidance with jet vanes (SAPPHIRE-1 and 2)
Parachute test (LES/ Tycho Deep Space)

They are all done with the smaller HATV rocket, except parachute test that is done with a LES engine on the capsule Tycho Deep Space

The reason to use HATV is they are well tested, cheap and fast to produce.
Lessons learned this year, will be put into next years HEAT size rocket.

I'm hoping that Copenhagen Suborbitals will someday get a dedicated section here at NSF.com. These launches, I hope will set a brisk pace of development. Their new sounding rocket seems to be a winner can't wait for the test launch.
Title: Re: Copenhagen Suborbitals
Post by: Morten C. on 09/12/2012 05:59 PM
Copenhagen Suborbitals have posted a sketch for their future direction.

TDS-1 that started as a testbed for parachutes systems, in the lack of being able to perform droptests from airplanes in Denmark, is now the design of choice in CS.
Out is the tube design, and a more classic capsule design is adopted, based on the test and work with TDS-1. Most of the subsystems developed for TDS-1, can be transferred directly into the new capsule.
How the new capsule, called Tycho Deep Space 2, will end up looking, will be decided in the next couple of months. What is known that the diameter is reduced from 2 to 1,6 meter, and aluminum (alloy: AlMg3) is considered, as the material of choice, to reduce the weight of the new capsule. Weight of the capsule is expected to be 500 kg, with a LES system weighing the same.

At the moment the engine department is looking at propellant alternatives to LOX/Alcohol. CS is looking at the WFNA / furfuryl alcohol propellant combination, because it have some properties that would be useful. Since it is more storable than LOX, MLP Sputnik will be able to fuel the rocket in the port of Nex° before sailing to the launch area, leaving one stress factor on land. Another property is that this alternative got more energy than LOX/Alcohol, and that in the end determines the size of the tanks, and length of the rocket. CS have released a report on the work with the test engine called Spectra. Static test have been conducted September 9, and more are expected in the coming time.

Doing the fall and spring, tests of the TM65 will continue, with the goal of making it a stable 65 kN thrust engine, that first will be tested and launch alone, and finally in a cluster of 4 TM65 engines on the rocket that will launch TDS-2. It is hoped that the first launch with a rocket with a single  TM65 engine will happen in summer 2013.

A November launch of the hybrid rocket Sapphire, is looking promising, and will give CS a first time chance to test an active guide rocket. Active guidance have been given top priority, and data is needed for the continued development of a reliable guiding system, for the use in future rockets. First one most likely a rocket with a single TM65 in 2013.

Been looking at blogs etc. and thought i would write a little update.

As compared to the other years, this year CS have been paying the cost of the home guard doing its launches. Because of this, the launch of Sapphire have been postponed to spring next year.


With the static test of TM65, schedule for next month, the engine is getting updated to use a pressure blow down system, instead of the nitrogen high pressure system used in the first test of the engine. It is hoped that with the new system the engine will reach 65-80 kN thrust instead of the 35 kN in the first test. It is expected that it is in this configuration the engine will fly next year.

It is expected that the test will be live streamed as the first test did.

Experience Bi-Liquid Engine TM65 Test at 125% Thrust (http://www.wired.com/wiredscience/2012/10/experience-bi-liquid-engine-tm65-test-at-125-thrust/)


CS is also conducting small test with the solid fuel Galcit, same type that have been used in the JATO boosters for take off of airplanes. First test was done 30. September, and 3 more tests was done 16. October.
As with the Spectra project, a report is being written, and can be found on the new resource area (http://copenhagensuborbitals.com/resources_downloads.php) on CS homepage where other reports also can be found. Please note that some reports are in working progress, and will be updated as test and conclusions unfolds.


Experiments with turbo pumps have also been kicked off with a single donation of $3500 out of the expected $4400 project cost. Two used fire pump have also been donated to the project, and been taken apart to see what need to be updated for it to be able to pump LOX. The pump will be designed to deliver 25 bar of pressure and will be outfitted with a gas generator. There have been talk about using a 55 / 45 mixture of sorbitol and KNO3, but that might be too hot, so T-stoff might be the answer. They have 25ltr. T-stoff for the starting tests, but are looking for a supplier for the future use, but at the moment have not found anyone. Test will show if it is possible to make a simple and cheap turbo pump, for use in future rockets. First test will pump water to see if the design work, before trying with LOX, and finally a static test on a TM65 engine.

CS have also been in talk, with the owner of the shipyard area, about the building of a new test stand VTC 3, that will be able to handle static test of engine up to 250 kN thrust. The new stand will be build 250 meter from where VTC 1 is placed, right next to the drydock. The engine will be placed in a 45 degree angle, that way making use of the water in the drydock as a flame deflector. Two 1600 mm spherical tanks tanks will be placed behind 800 mm concrete. With this new test stand CS will be able to find out if the future 1.6 m diameter rocket will be using one big engine or 4 TM65 engines.

As mentioned elsewhere CS is doing a crowd-funding on Indiegogo for the new TDS II capsule, but might have gotten into problems with the US OFAC, because of the cuban cigars flown on TDS I. You can read more about that on the Rocketshop blog, as well as studies of hull design, helping out with hatch design, temperature control of the body and reaction control system.

Good to hear. I have written to Copenhagen Suborbitals Support, and asked if they could put todays test on livestream.com, so it can be watched offline.

Btw the streaming software SnowMix, that is used is coded by the people in the StreamTeam that runs the streaming for CS.

Got a photo of the caravan that was used by the streamteam today.

Got more photo from inside the workshop HAB, that was open after the test, so we were able to see what CS was working on. If interested I can put some of them on here

  I watched the time carefully, and noted the burn
lasted from about 37 seconds into the video until minute 1.07.
30 seconds in all. Any disagree.

So a 1/2 minute burn successfully accomplished.
Well done. Wunderbar!

So Copenhagen suborbital now has proven a rocket motor capable of
sending a sounding rocket upto 30 km.
Or perhaps upto 100 km.

Copenhagen Suborbital has shown remarkable success for a small
private group. Even a previous partial success for a sounding rocket launch
reaching ONLY eight kilometers altitude is remarkable, considering
that is the cruising altitude of many commercial jets.

On the first test there was a heat exchanger that took the N2 around the nozzle and up to the tanks. But this time the tanks was pressurized with helium prior to the ignition.

There was also put in an extra set of smaller valves for the pre-stage, where as in the first test the main valves was just opened to the tanks, that at this time was under low pressure, before open up for the N2 pressurized gas to the tanks in main stage.

This could not be done this time as the tanks already at 20 bar, so smaller valves was used instead.

Post by: spectre9 on 11/18/2012 11:41 AM
Thanks for that very interesting.

I found a video on the CS webpage that said it was a helium heat exchanger but they were moving to N2 as it's cheaper.

So I'm confused and guessing maybe you got mixed up here?

True that they in the video said it was for helium, but the first test they did  they ended up trying N2.

Here is the read out from the first test, where you can see the nitrogen gauge

Found an old blog where Peter Madsen, explain the changes that would be made from the first to the second test. Mainly the change to a pressure blow down system.

Maybe they still need to focus on the pressurization system to replace the expensive helium.    They know the engine works; just need a less expensive pressure system.

Well they are looking into turbopumps so we will most likely see a TM65 engine test with a pump in the future, but I imagine we have to wait at least to late 2013 (But then again CS have surprised me before, and I did get a picture of a pump lying on the floor at their workshop this Saturday). At the moment the engine use a pressure blow down system, and most likely the flight version of the TM65 too, that is planed for 2013.

Things can move fast in CS at times, and the development is not always linear, as there is more projects going on at the same time (not only in the engine department). It is the result of these project that will determine the direction they end up take.

Quote from: Peter Madsen
We still have not seen TM65-engine full potential. In today's test we reached 9.5 bar, and Tordenskjold is designed to run at 12 and could handle 15

We had 18.7 bar LOX and 19.2 bar on fuel, so it was close to the desired 20

It was a wonderful experience to see the 50 kN as we got this time.

TM65 is a little too conservatively designed, and if we are up on the 12 bars, we either run with unreasonably high tank pressure or drill the injector. We have seen it plenty of pressure drop across the injector and also running with the correct ratio between fuel and lox.


A new test is planed the December 30

CS have just released a video of the TDS-I capsule that was tested in a LES experiment last summer. The video consist of a run through and test of the subsystems, the LES launch itself and some conclusions at the end of the video. Some of the footages have been seen else were, but this time put into a video telling the whole story. There is also talk about doing a final drop test of the capsule from an airplane in the spring of 2013, to validate the parachutes.

http://www.youtube.com/watch?v=YCFIGf_0US8

2012 have been a busy year for CS. Kristian von Bengtson have released this graphical overview of the year. A bit amazed myself of all the things they have done when it is put up like that. Certainly look forward to 2013 with another year of development and experiments.

The year will end with a static test of TM65 on the 30. December, where CS hope to get the engine up to its full potential. The setup will be the same as the last test, but this time the injector have been drilled up to get a bigger flow of the fuel into the combustion chamber.

Post by: Morten C. on 12/30/2012 10:51 AM
Amazing they made it, since the LOX tank didn't pass the pressure test, last Wednesday. My understanding of it was, that some highressure valve that was changed, and the tank did not pass the test to 36 bar, so it could handle a norminel 24 bar pressure. The tank was cut up and a new was made and pass the test friday, although only to 30.2 bar, meaning they run the test with a tank pressure of 20 bar, and not  24 bar that they have been hopping for with the old tank.

But good save

nominal up to 14 sec, then something goes wrong. End result is a burn through in the engine. Last images in the video show the result. They didn't sound that much worried about it and could be easy enough to rebuild for other tests. So that might mean another static test with a pressure system, before a pumped version is tested.

Today at 1400 the minutes were TM65 start signal for the third time. All valves and primer functioned as they should. The engine got propellant at a record high feed pressure.

The ignition was nominal.

Then wrecked TM65. It was not melting, it was not an explosion, but the implosion of the rear portion of the inner casing of the engine. Action does it look like new, but the nozzle inside is folded.

It was a structural collapse of the lightest part of the nozzle. One area that we have not actually seen as critical until relatively recently.

Design Analysis of the new large engine have shown that this area is very hard structurally overloaded.

Deformation of the nozzle happens going from pre stage to main stage, also seen in the video below at 0.30 min, where you also noticed the odd flame shape as a result.

(https://lh3.googleusercontent.com/-lo_ayIOvK0w/UOCdhwObC9I/AAAAAAAAHV8/g07xkDCKzPQ/s720/TPE-13.jpg)
Thomas Pedersen/CS

Because of the deformation the fuel flow is below normal, also seen in the video on the gauge that shows the fuel pressure drop much slower than the LOX does. At 1.28 min the inner wall collapse due the lesser cooling of the engine, and giving the fuel another way into the chamber. This can also be seen on the gauge where the fuel pressure now drops much faster.

Thomas Pedersen/CS

This engine looks like it is going in museum and a new will be build. There might be build two, one flight version and another as test bed for pumps, if they do not use the same for both.

This will also postpone the building of VTC3 until there be use for it in the test of a TM250 model of the engine there been talks about. This is due to that a new TM65 engine can be build so that the pumps still can fit into the VTC1 test stand as it is.

Happy new year everyone

Latest news from Copenhagen Suborbitals

The entire crew of Copenhagen Suborbitals are working hard these days. Summer is coming and in a short time we will attempt to launch our first actively guided rocket "Sapphire". Sapphire is a test vehicle. It's only purpose is to verify that our guidance software and control systems work.

As mentioned before the Sapphire rocket is not built to reach space - but will give us invaluable information on active guidance and how to control a rocket in flight. We will use the test results to evaluate and upscale the guidance system so it can be used to guide our bigger rockets that are already in production.

The launch window for Sappire will be annonced very shortly. As always we will provide a live and commented video feed of the launch. While you wait we have compiled this second video where Lead Guidance Officer Flemming Nyboe explains how Sapphire's guidance system works.

Well over a year for even a first attempt, yes.

From actually doing they discovered the difficulty of unguided flight, so they had to learn how to do guided flight.. with all the electronics that entails.

In the process, they did what no amateurs have done since the 1940s: turbopumps. If they really build and fly a turbopump driven rocket next year, it'll be an amazing feat.

Sapphire rocket launch dates

Last week Copenhagen Suborbitals had a succesful live rehersal of the upcoming Sapphire launch. The Sapphire launch vehicle was stacked on the mobile launch platform Sputnik, and together with our mission control ship Vostok we performed a "plugs out" test where all Sapphires subsystems where powered up and a complete launch sequence performed. Everything worked as planned, and thus we have now decided to release the possible launch windows.


The picture to the right shows Sapphire stacked on the launch rails with the service tower next to it. In the bottom of the rocket - just below the fins it's possible to see the 4 solid copper jet vanes controlled by 4 individual servos. The 4 servos are controlled by a IMU placed in the payload section of the rocket.

Sapphire facts:
Actively guided hybrid rocket
Height: 6 mtrs
Diameter: 220mm
Weight: 206Kg
Fuel: Polyurethane
Oxidizer: Nitrous oxide (N2O)
Expected burn time: 24 sec
Expected max. altitude: 12000 mtrs
Expected max. velocity: 340 mtrs/sec   

We have two potential launch windows. The primary is June 22-23 with June 29-30 as backup. The actual launch timing is higly depedant on weather conditions and will be announced as soon as we know. Updates and chenges will be sent out via email and published on our website .

We are now at T minus one week.

And everything is ready. The mobile launch platform "Sputnik" is loaded with the Sapphire rocket and all the necessary equipment - and she is ready to embark once the weather allows it.

Sapphire is sceduled to fly June 23th at 9 AM CEST (UTC+2) but the timing is subject to change. We depend a lot on the weather conditions and rigth now we estimate a 50% chance of "on time" launch.

While we wait our video wizard Claus Meiling has compiled this 20 min documentary on the final preparations of Sapphire. Please also make sure to read this description of Sapphires telemetry system by our Flight Dynamics Officer (FIDO) - Steen Andersen.




Watch the launch live in HD from your computer.

As allways our dedicated "Stream-Team" are ready to broadcast the launch. Since the LES and SMARAGD launch in 2012 they have worked hard on various improvements. This year we have installed 8 HD cameras that covers all areas of interest. There will be 3 cameras on the Sputnik Launch platform and 5 on the Mission control vessel "Vostok". The cameras will be turned on once the two vessels are in place at the launch site in the Baltic Sea.

The launch will be broadcasted in HD on Youtube. The entire event will be commented live by our two space experts Steen Eiler J°rgensen and Michael Linden-V°rnle. Also Peter Madsen will be CAPCOM during the last minutes of the countdown and during the mission itself.

The live video feed will be available on:  www.copenhagensuborbitals.com.

Please make sure to check regularly in the days prior to launch. Any updates or changes in scedule will be announced as soon as possible.

BPM5 Static Test 1 - Atmosphere Video

Published on May 15, 2015
10. of May 2015 Copenhagen Suborbitals tested their BPM5 rocket booster for the first time.

Three static tests was performed during one single day. The BPM5 booster survived the three tests, and will undergo further tests in the near future.

In this video you get to experience the splendor of these three amazing BPM5 static tests

You will get to see the three static tests in a video collage of videos from up to six camera angles

Also included are interviews with two key members of Copenhagen Suborbitals.

In addition to this video, we have released a Technical Video with material from the same test day. That video contains all camera recordings including High Speed footage in full length. The technical video can be found at:

Rain expected

Schedule change to may 31st.

What will be tested on Sunday May 31st

ĽCommissioning of optimized injector (sn. 002) with larger LOX channels than injector 001. 7 sec burn
ĽCommissioning of automated pre-to-main stage transition. 2-3 runs of 7 seconds at different prestageangles of the main valve.
ĽTrimming the operation point to a chamber pressure at 15 bar. 2-3 runs of seven seconds.
ĽInjector mode characterization. 1 run at > 20 sec blow-down burn with the starting chamber pressure of 15 bar.
ĽDPRľbased automated pressurization (the function we will make use of on the Nex° 1). 1-2 runs of 7 seconds. (DPR may not be ready for Saturday, but we are struggling to reach it)

So we are looking at up to 10 burns!

Due to an error on the main valves the engine never transitions to a full main stage mode. It is however interesting to see how the copper vane burns away and the graphite vane lights up!

Looking for more funds.....

Progress report on the rocket:

 All available hands are working on getting the rocket ready. We're also doing the final touches on our launch platform and support ship. So it's a very busy time in HAB.

 Monday evening both the fuel and LOX tanks have been pressure tested and passed. Work on the cable tree for the rocket is also progressing great.

 At the moment we're planning a launch attempt on August 21-23. If we can't make it then the last weekend in august and the first two weekends in September are also in scope.


Now back to work. We have a rocket to assemble.

Even through the weather is getting better at Spaceport Nex° there will not be a launch this weekend. We have had a visit from good old Murphy. Some of the checkout tests needed before the rocket can be flight qualified has taken longer than expected.

 This weekend we will perform the final tests and after that the engine section will be disassembled for LOX cleaning, reassembled and final checkout procedures performed. We aim for launch the weekend 26th -27th of September. The long term weather prognoses look promising!

Nex° I mission is postponed

Unfortunately, we'll have to postpone the launch. The last week has revealed minor, but numerous, problems with the rocket's system. We're extremely close to being able to fly, but right now we have no other choice but to wait. Launching at sea means that the weather is a decisive parameter, not least due to water temperature. This is a very tough call, since the team has literally worked day and nights, nights and more nights. But safety first.

We will present more information, and not least a new timeframe for the mission, as soon as possible.

To you, loyal supporters: This is all possible because YOU believe it's possible. Without the support from around this planet, we'd be nowhere.

I agree with the poster on YouTube that there might be an embrittlement issue with the glass/resin insulation ring/gasket.  I wonder if they can maintain a metal/metal seat (thus maintaining structural integrity) at the flange while still employing the insulator over most of the mating surface reducing the heat energy transfer from the engine compartment.

Also mentioned "icing" in the engine compartment.   A small amount of GN2 (pad resource) might displace any water vapour present in that area to help prevent condensation and ice formation.

Then again, if the insulator works well, that might take care of the icing problem.

CS released an update with a couple of videos
Copenhagen Suborbitals have begun pressure forming of standard sized tubes in 6 m length to use with the BPM-5 rocket engine. The BPM-5 was not designed to use standard sized piping. In hindsight this was a mistake, since welding these specialized tubes for the BPM-5 by our supplier is quite cumbersome and time consuming. We therefore decided to try hydro forming standard sized piping instead so it can be used for the BPM-5. We are using about 85 bars of water pressure to go from the standard size of 108 mm (outer tube) to 112,3 mm and 101,6 to a 104,5 mm (inner tube). So far it has been a great success. The hydro forming extended the size and the deformation hardened the tubing. The average size increased within 0,5 mm over 6 mm length.
Now the tubes have been cut to length and are ready to go to metal forming.

Well, I saw a lot of pipe, not a lot of engines. My guess is that they expect to burn through a lot of material making a few engines and burn through a number of engines testing them. That said, it's been a while since I heard what the plans are for this engine.

The Nex° 1 and 2 rocket will use the BPM 5 engine. As I remember the plan have always been to build a high number of BPM 5 engines, and test them. There have been a few production issues with the first 3 engines, that is taken care of with this new batch. This might also bring the build time down for an engine.


The DPR system have not been tested with the BPM 5 engine and then you have all the TEOS/ethanol testing.

Second Cold Flow test on Nex°1 (in 2016)

Copenhagen Suborbitals

Published on Jun 13, 2016
This video is from the second cold flow test done on the 11 of June 2016 in front of the workshop. A second test was needed to test the repairs and small changes made based on what we discovered during the first test. Several valves and seals were changed, and most was fixed. A couple of minor things still need adjusting before launch.

The cold flow test is done with liquid nitrogen instead of the LOX. Nitrogen being inert is the perfect replacement and makes it save to troubleshoot while being close to the rocket.

Copenhagen Suborbitals is the world's only manned, amateur space program, all 100% crowdfunded and nonprofit. In the future, one of us will fly to space on a homebuilt rocket.

OK, I was too tired at the hotel and also lots of stuff to do on Sunday as well, so I will skip the image editing.

They did 4 burns, with some troubles with the igniter before the first burn and some high pressure system troubles in the last two burns, but troubleshooting didn't take too long. Objectives were to test the pressurization system and to characterize the engine parameters, and to compare them to their previous (supposedly identical) unit. All in all, quite interesting day. Very chilly (~2 - 3 C) and very, very foggy, and with a slight breeze. Typical summer day in Finland. A visitor from Germany was getting really cold and left after the 2nd or 3rd burn :D We international visitors also got to see the burns in limited groups from a photo bunker or a downrange location. One of us got permission to set up his own camera... which was very (un)lucky as it caught the flying igniter! No damage, as the lens was covered by a $5 chinese filter....

Strangely the sound was quieter in those locations compared to the visitor area - maybe the freight container amplifies the sound in strange way to different direction.

Here's some plots posted on their FB page:

They have to top the excitement from NEXO 1 delivered in some way. ;)
I wonder where they got that tank, at first glance 20 liter is not exactly common. (As carbon, in steel it is.)

From the video:
Nexo 2 will use jet vanes once more.
Modular design, by sections.
"Clear the tower, then start steering."

No more prepressurized tanks, adding a 20 liter 300 bar helium tank. ~20kg for the COPV tank itself. Independent dynamic pressure regulation for fuel and LOX, they need to be ~1 bar apart.

O/F ratio at 1.3
Not a constant tank pressure, constant injector/chamber pressure. Same fuel and oxidizer flow at all times.


Exiting times, this starts to look like a real pressure fed rocket.
Lets hope for more launch and less anti ship missile this time. ;D

Title: Re: Copenhagen Suborbitals Updates and Testing
Post by: ChrisWilson68 on 08/13/2017 05:38 AM
Peter Madsen has now been charged with involuntary manslaughter.  He had a journalist on the sub earlier the night of the sinking.  He claims he let her off safely, then continued on his own, then the sub sank.  He abandoned the sub just before it sank.  That was Thursday.  She has not been seen since.  The sub has been recovered, but authorities have not yet entered it.

About spaceflight, the New York Times claims:

Quote
Mr. Madsen had planned three launches this summer in preparation for a possible space mission in 2019 with only himself onboard.

If its like any other scandinavian murder mystery, it's only going the get more gruesome from here onwards...

I think its important to remember that no-one is guilty before a trial. Having said that, it now seems that Madsen has changed his story as to when he let the journalist off the boat (we don't know the new version as it has not been made public), sourced from here: http://www.aftonbladet.se/nyheter/a/dVXVj/dansk-polis-ingen-person-hittad-i-ubaten

I think its important to remember that no-one is guilty before a trial.

I agree with the sentiment about not jumping to conclusions.  But, that's not really an accurate representation of the "presumed innocent" idea.

As soon as a crime is committed, the perpetrator is guilty.  It's just that in many cases few people know it.  Until a verdict is reached, the legal system does not claim the person is guilty or not guilty.  That only happens when a verdict is reached.  What "presumed innocent" means is that if the evidence isn't clear one way or another, the verdict is to be not guilty.

Also, the fact that the legal system makes a determination one way or another doesn't mean that everyone is required to agree with that decision, or to hold off judgement until that decision happens.  Everyone is entitled to their own opinion, and to express that opinion.

As the OJ Simpson example shows, it's even possible for one part of the legal system (the criminal justice system) to hold someone not guilty while another part (the civil justice system) holds that same person responsible for the very same crime.

Copenhagen Suborbitals will not participate in online debates about "where is the body" or "what happened".

The knowledge members of Copenhagen Suborbitals have about the submarine and Peter Madsen's use of it, we make available to the Police and Courts in the pending investigation and trial. It's the right forum for that kind of thing. "

We can not really do more now besides taking the phone if the police or the Navy call for further information."

Madsen's story has changed.  He no longer claims he dropped off the reporter safely on shore.  Now, he claims she died accidentally and he buried her at sea.

Because, of course, the most reasonable thing to do when someone accidentally dies is to dispose of the body and flood the place that it happened, getting rid of as much evidence as possible of what really happened, then lie about it and say she didn't die at all.  Nothing at all suspicious about that.

I'm sorry for inappropriately posting this here, becouse there's no relation with Copenhagen Suborbitals what so ever. The latest news on the situation concerning Madsen.

Multiple news sites report that a torso (without head; arms and legs) has been found at the island Amager. A cyclist spoted the remains. DNA research has to be done to determine the identity of the remains.

This gets stranger by the day.

Edit: the Telegraph (http://www.telegraph.co.uk/news/2017/08/21/body-found-danish-submarine-man-says-missing-journalist-kim/) and the Guardian (https://www.theguardian.com/world/2017/aug/21/missing-journalist-died-in-submarine-accident-inventor-tells-police) reported this horific news.

Official update:

The Nex° II rocket remains grounded on land until summer of 2018

The Nex° II rocket remains grounded on land until summer of 2018, the board of Copenhagen Suborbitals has just decided.
 
Launching a rocket is a large-scale project. A lot of different parameters must be fulfilled in order for the Nex° II mission to be optimum, and this year it has simply not been possible due to both internal and external delays combined with bad weather conditions.
 
Next week was our last launch window but one of our stakeholders was not able to be there during the launch and we couldnĺt get the airspace cleared.
Thatĺs why we have now finally decided to exercise due diligence around the project, hence postponing the launch of Nex° II for weather conditions again to be favorable.
The mission is still on, and we are launching Nex° II in the summer of 2018.
Until then, you can see the Nex° II rocket in the Copenhagen Suborbitals headquarter at Refshale°en in Copenhagen.

Very interesting video. Not so much for what it shows (it's known as a reefing unit IIRC) but the methodical way they have designed it, and documented it.

Note how the buzzer sounds. Unnecessary in actual use but very handy for ground safety. Note unit is self contained. No control or power wiring needed. A straight timer (with the timer amount labelled).

The design seems to be single string, with no 2nd cutter, but I think that's a minor quibble, and in practice I'm not sure how much use a 2nd cutter would be.

If all their work is to this standard they may be slow but their hardware looks to have a high likely hood of of working.

So, why didn't the third parachute inflate fully?
Well, to be honest, a human error was to blame. The reefing line that goes around the bottom of the parachute, wasn't routed correctly through the cutter. So even though the cutter activated as it should, it couldn't cut the line.

So, why didn't the third parachute inflate fully?
Well, to be honest, a human error was to blame. The reefing line that goes around the bottom of the parachute, wasn't routed correctly through the cutter. So even though the cutter activated as it should, it couldn't cut the line.

That had to have been incredibly frustrating. Seems like a fairly obvious mistake that should have been picked up, but then it's easy to solve world hunger from my armchair too.

I have the opposite view. Better to find this potential error in testing than in flight!

It has been some years since we worked with big rockets. The new capsule mock-up is just a fraction of the Spica rocket, but the real sense of scale just got way more palpable.

Pre-flight static test of the BPM-5 engine on May 5th 2018

On May 5th we conducted several successful burns of the BPM-5 engine. The goal of the test was to qualify the engine controller software for flight on the Nex° II rocket, but we also managed to sneak in a few tests with TEOS as fuel additive.

J°rgen Skyt and Anna Hovalt gave Nex° II the final layer of beautification.
If we have miscalculated a bit, the Pioneer reference may even come into play 👽

We're planning two parachute tests at Odense Airport this Saturday.
1: For the first time in the world - A manned ballute test!
2: A test with 3 main parachutes in a cluster
For the parachute test, we've placed a camera at the apex, testing it before Nex° II Blue skies! ☀️

Today's triple-cluster parachute test was a complete success with perfect opening, perfect 2-stage unreefing and a landing spot almost as expected.
Fantastic day at Odense FaldskŠrmscenter.
Thank you so much for you hospitality and support.
Blue skies!
