It looks like some crazy Finns, me included, are traveling there to see and hear it. Wish us luck...

I'm planning on targeting my trip to see extended family in the Greater Scandinavia Region around the next series of tests. It would be my third visit to CopSub.

Yes! Successful tests today. I will put an arrow to that picture when I get to the hotel.

Also: bigger rocket engines are loud.  :D

Second burn was successful

Purging the engine after a burn gives a very dramatic effect.

Here's the archived live stream of the tests:

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:

Tomorrow we'll test the model of the manned Spica space capsule in a windtunnel.
 We're so excited!

Isn't that one of these "wind tunnels"?  :o

Yes. They mention at the end of the video the Copenhagen Air Experience.

test assembly of the Nex° II stack.
The nose cone might need a few more finishing touches...

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

Thrust Vectoring Gimbal:

Also answers for someone, why to cumbersome (overkill) electric-hydraulic design vs. pure electric one.

(Scalability...)

The complete story of Nex° I


Copenhagen Suborbitals
Published on May 23, 2017

In the summer of 2016, Copenhagen Suborbitals launched one of the most advanced liquid fueled rockets built by a team of volunteer amateurs.
Follow the team close up during final preparations for the launch and during the launch of the Nex° I rocket.
Enjoy.

They clearly have been posting pictures and videos on social media recently, building parts for the Nex° II vehicle. They have gotten great publicity. I may have missed it, but are they going to try to launch this summer still?

That is still the goal. Look like they'll launch in August. [Source]
