The video’s show the HYDRA 4X hybrid rocket motor testing from the Fall and Summer of 2018.
ERIG is a team of students from the Technical University of Braunschweig, developing and constructing experimental rockets. HYDRA 4X produces 2000 N of thrust and will burn for 15 s propelling the team’s FAUST II rocket to 10 km in altitude.
Stepping away from the amateur side of things but this video series on Nammo’s launch of their Nucleus sounding rocket is pretty cool and worth a watch.
The 30kN thrust, 356mm dia hybrid rocket uses hydrogen peroxide and HTPB fuel, and flew to 107.4 km in September of 2018, making it the first hybrid rocket to reach space.
Video Caption: On March 3rd, the Rice Eclipse team conducted two hot fires of the Luna hybrid rocket engine. The first test, the seventh of this propulsion system, implemented gas injection thrust vector control and a new impinging injector plate geometry. The second test used a recently machined combustion chamber and bulkhead as well as a new batch of chemicals.

Video caption: As part of the University of KwaZulu-Natal’s Aerospace Research programme, the test was part of a plan to develop expertise in rocket propulsion technology.
The plan? To send payload-carrying rockets into short suborbital flights before returning to earth. Masters students and industry experts waited in anticipation to see the two-year-old project take off.
Relive the excitement and tribulation of the Stratos III launch.
The team is still investigating the cause of the failure.
Video Cation: Test fire of Cal Poly Space System’s experimental rocket engine, Hybrid Motor 7 – Heavy. The test occurred on January 20, 2018, in the Cal Poly Propulsion Laboratory.
