CS Recent Engine Testing and Walk-through of Nexø II

As Copenhagen Suborbitals work towards launching their Nexø II this summer, the team have been busy carrying out further BPM5 engine testing and preparing the rocket for flight.

An engine test was recently carried out on May 5th where the main purpose was to verify the code in the engine controller. Five tests were conducted, with the team also experimenting with different fuel mixtures.
You can read more about those tests here, data included!
And check out the full album of the day’s test activities here.

With the upcoming launch, the team have provided a walkthrough video of the rocket explaining it’s features. The rocket is a stepping stone towards the much larger and human-rated Spica rocket. To learn more about the rocket you can also check out the team’s info page here.

A slightly foggy day – BPM-5 engine test day

the 4th of February 2017
As something new, we used our pressurisation system actively by changing the engine chamber pressure along the way. We tried to keep the O/F ratio constant and change the feed pressure so the chamber pressure would increase.
We would then be able to map the O/F ratio and chamber pressure with just a few tests.

CS 35sec BPM5 Burn

Video Caption: On October 10th 2016 we put our BPM5 engine through the longest burn to date. In 35 seconds it provided a total impulse of 180.000 Ns.
On the data overlay pressures are given in bar, temperatures in degrees centigrade and thrust in newton.

BPM-5 – 4th Static Test

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

CS BPM-5 Control Vane Test

Copenhagen Suborbitals recently conducted another static test of their BPM-5 rocket engine. This time the tests were to test a graphite and copper control vane in the exhaust, these control vanes will be used on the Nexo class of rockets enabling control in pitch ,yaw and roll for a guided trajectory.
