2013.06.23 NEWS

*A Motor Team telecon was held this weekend to discuss the DSS TM-2 motor test and to come up with a recovery plan. Attendees were Rick Maschek, Paul Avery and Richard Nakka.

Details of the TM-2 motor preparation, assembly, test firing and post-burn inspection of the motor were presented and discussed; in particular, any deviations were noted from the test plan. As well, differences between the TM-2 motor and the earlier successful TM-1 motor were noted and assessed. Test data such as chamber pressure gauge readings were carefully reviewed in an attempt to come up with an explanation for the anomaly. A failure of the Chamber Separation Disc (CSD) was discounted as the cause, as there was no evidence to suggest an off-nominal performance of this component.

A comparison was made of the pressure readings of TM-2 with the earlier successful TM-1, and with the BPS motor, which also CATO’d. It had been concluded earlier that BPS failed due to catastrophic propellant fracturing during motor startup. The comparison proved enlightening. The chamber pressure rise for TM-2 was much more rapid than TM-1, and was similar to that of BPS. It was agreed that propellant fracturing upon startup was therefore the likely cause of the TM-2 CATO. A conclusion could not be reached as to why the two nearly identical motors (TM-1 and TM-2 ‘first burn’) behave differently at startup. There were no significant differences in the two designs, assemblies or ambient conditions.

Based on the negative experiences with “cored” grains (e.g. BATES, Star) which can be subjected to significant tensile stress upon motor startup, it was concluded that scaling up of sugar propellant motors has its challenges. In particular, cored grains are best avoided, and a non-cored grain configuration is the most promising way to go. A grain configuration that is subjected solely to compressive loading on startup will be tested next.

Rick suggested that a “success” criterion of three successful firings, in succession, be set. This was agreed upon and work is already underway to repair the TM-2 motor (as a single burn configuration). Test firings will take place in the near future at our alternate test site in the Mojave Desert (since FAR is currently unavailable to SS2S). These motor tests will be designated DSS TM-4A, TM-4B and TM-4C. Upon successful completion of these tests, the ‘six-grain’ DSS TM-3 motor (currently being worked on) will be test fired.

*Blair and Richard Nakka have nearly completed the machining of the DSS TM-3 “nozzle adapter”. This component will be used to adapt the BPS nozzle to the 7 inch (178 mm) casing. The part still needs to have the 20 radial holes tapped, and then a chamfering of all cut edges.

I was curious about propellent grains and stumbled upon the following, useful link for the layman:
 
   http://www.nakka-rocketry.net/th_grain.html

From this I would assume that by switching to un-cored grains they will reduce the overall thrust significantly.

   OK!
I'm going to repeat some facts that I've posted on another thread, elsewhere.
  Sugar (preferably glucose) mixed with saltpeter can send
a rocket to space on an up and down flight.

Specific impulses of about 150 seconds are doable.
I  designed such a rocket (with aerodynamic, parallel ribs for strength)
that would have had an elegent mass ratio of 4.5.
Loge(4.5) = 1.5

Problems are?
Trying to order large quantities of glucose (from India).

And mixing saltpeter and glucose by heating them is dangerous.
If you want to do it safely, wear cotton coveralls (no polyester or nylon)
and have a face shield on at all times.

UPDATE VIA SS2S's FACEBOOK:

Quote
2013.07.14 NEWS

*Rick Maschek has completed fabrication of the avionics support “discs” that will be used for mounting the avionics components for the DSS DART rocket, which is targeted to have its maiden flight on July 20th (less the avionics package). The flight of the DART with the avionics is targeted for August 24th.

*Rick has obtained suitable-sized aluminum plates for casting the new DD-Slot grain. The plates will act as formers for the sides of the two opposing slots.

*Craig Peterson has kindly accepted the task of making a Retainer Ring for the Forward Bulkhead (FBH) of the DSS TM-4 motor. The rationale of using a Retainer Ring to hold the FBH (rather than direct FBH attachment to the casing) is to mitigate potential damage to the FBH in case of motor overpressurization.

*The 7” (178mm) aluminum alloy tube for the DSS TM-4 rocket motor has been ordered, and is being shipped to Randy Dormans. Randy has kindly accepted the task of drilling the indexed holes for the Nozzle and FBH Ring attachments.

*Vicente Alvero Zambrano has offered to conduct the propellant characterization “DoubleSShot Characterization of KNSB propellant with regard to curing rate and associated mechanical properties”. The intent of this research is to better understand the curing and slumping behaviour of KNSB, particularly with regard to variation with temperature. Vicente has already started to make the moulds for casting the specimens. (photo posted).

*Keen effort by Vicente has resulted in the donation of a 900 MHz. heliaxial antenna from Circular Wireless:
http://tinyurl.com/qdk7zgc
The antenna will be sent to Chris King for use with our avionics telemetry.

*SS2S main sponsor Markus Bindhammer has provided another update on the Cosma humanoid robot project. Markus reports “The mechanical construction is so far finished. I might change the stainless steel screws by aluminum screws to save as much weight as possible”. Photo of the Cosma prototype body has been posted in the DualSShot album.

Seems SS2S goes on an update blitz sometimes.   :D

*Craig Peterson has completed the task of fabricating a Retainer Ring for the Forward Bulkhead (FBH) of the DSS TM-4 motor. The Ring will be sent to Rick Maschek for integration to the TM-4 motor. Photo posted.

*Richard and Blair Nakka have completed the next step in fabricating the Sliver Catcher for the DSS TM-4 rocket motor. The 6.5” (165mm) steel disc has had the required 22 holes made. The next step is to apply the ¼” (6.4mm) ablative layer for thermal protection. Photo posted.

*Randy Dormans reports that he has completed the task of drilling the indexed holes in the DSS TM-4 motor casing for closure attachments. Rick has arranged to pick up the casing on August 4th.

*A regular Avionics telecon was held this past Sunday. In attendance were Chris King, Rick Maschek, Daniel Hastings and Richard Nakka. Daniel reported that he has completed the Breakout box (for testing the UFC-4) and has sent it to Chris. Daniel was assigned the task of finding a suitable rate sensor for the de-spin control circuit that can detect a roll rate of 2000 deg/sec or better. Chris reported that he has started installing the avionics support discs and that they fit well. Rick reported that the DSS DART did not take to the skies on July 20th as scheduled, due to an unplanned loss of the altimeter unit. That maiden flight has been rescheduled for August 24th.

The DART with avionics package aboard is now scheduled to fly on August 30th. The purpose of the DART flight was summarized as follows:
Testing of avionics package components:
*UFC-4 Flight Computer and antennas
*Telemetrum “backup” altimeter
*Radio beacons for recovery
*Amateur TV transmission
The package will be flown in a strictly passive mode with simulated pyros (8 in total). The next Avionics telecon will be held August 11th.

*Ben Brockert has performed a Solidworks analysis to estimate nosecone heating at hypersonic velocity. The latest results are provided here:

*The test report prepared by Vicente Alvero Zambrano detailing the experimentation performed on various ablators has been uploaded to the SS2S Documentation page. http://sugarshot.org/documentation_old.html

*Vicente Alvero Zambrano has made progress with preparations for conducting the ablative heating experiment for the nosecone tip. Photos posted.

*Craig Peterson has kindly agreed to machine the three throat inserts for the DSS TM-4 motor. The three inserts are all identical except for the throat diameter. These steel inserts allow for simple change of throat diameter to allow the TM-4 motor to operate at different chamber pressures, starting with the lowest pressure for the first test firing. This approach was considered to be a wise precaution, since the DD-slot grain has not been tested before.

*A regular Avionics telecon was held this past Sunday. In attendance were Chris King, Hans Olaf Toft, Mattias Lampe and Richard Nakka. Chris reported that he has largely assembled the avionics into the new DART support structure. The sole component left to be mounted is the video camera. Hans reported that he has nearly completed assembly of one copy of the DSS avionics board (switches, connectors, external boards, sensors, etc). Testing so far indicates that nearly all is working well. The sensors, with the exception of the pressure transducer, seem to be working.

The gyros currently appear to be a tad ‘noisy’. All switches are functioning. The feature which allows switching from Pad power to Internal power is working. Mattias reported that he has produced additional copies of the circular antennas that are being used for the DSS package. Richard reported that he attempted to start up the electric motor for the de-spin system, but was unsuccessful in getting the motor to operate. The motor being tested is an Turnigy Brushless Outrunner motor, connected to a speed controller and servo tester unit. One of the components may be faulty, according to manufacturer’s Technical Support.

Richard also reported that the maiden flight of the DART has been postponed one week to Aug.31 and as a result, the DART flight with the DSS avionics has been pushed off by a week, to Sept.7th. This delay was considered prudent to accommodate extra work being done to prep the DSS TM-4A motor static firing, also expected to occur at the end of August. Photos posted.

The Sugar Shot to Space project (launching a sugar fueled rocket into sub-orbital flight) has taken a new direction after problems with up scaling their 'dual-pulse' single stage motor concept. The new direction will be to focus on a more conventional 2-stage rocket to reach space (100km).

100mm (4") LOX / WAX hybrid rocket motor test 06-24-2015

mojaverockets

Published on Apr 26, 2016
Too much LOX on board, motor ran out of fuel but LOX kept flowing burning up the liner, other wise nice burn. In a perfect world, the oxidizer and fuel run out at exactly the same time, in less than perfect burning, you hope to run out of oxidizer (LOX) first. At 0:54 seconds into the video you can see the paraffin fuel being extruded out the nozzle.
