ERIG STERN II – Hybrid Engine Test

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.
