The student team conducted the first hot fire on their new test stand, which also happened to include the first hot fire of their newest 3D printed rocket engine, Ignus-II. Ignus-II is printed from Inconel 718, produces ~ 800lbf (3.5kN) of thrust and burns liquid oxygen and kerosene, the engine improves upon the earlier Ignus-I engine.

The test was conducted on June 16th, 2018 and marked the first test of both Colossus and Ignus-II. This completes the Verification and Validation stage of Colossus, meaning that Colossus is now available for other university team use!
Video Caption: This was the first hybrid engine test within STERN II. The engine Hydra 4X was developed and manufactured by students of the ERIG Team and tested at the test site of DLR Trauen. It uses the propellant combination nitrous oxide and HTPB. The video shows the engine with CFRP coating and yellow measurements stripes for temperature measurement of the engine surface. The test results will help to improve the engine regarding manufacturing and performance.
Joe Barnard of BPS.space has flown his 1/48 scale Falcon Heavy model demonstrating the ability of the Signal flight computer to control a 3 core rocket. Each core was equipped with its own Signal FC and TVC (Thrust Vector Control) mount, by firing the two core boosters at liftoff the combined TVC control allows the rocket to pitch, yaw and roll about its axis.
As is demonstrated in the video below, the rocket executes a 20° roll program after liftoff and holds this until burn out before the centre core takes over and flys away.
The model even has a second stage fully equipped as well, lets hope we see an all up test soon!
A pretty awesome feat!
I’ll let the video do the rest of the talking!
