DARE | DHX-400 ‘Nimbus’ Hybrid Rocket Test 9

Video Caption: A student society that builds a record-breaking hybrid rocket engine powerful enough to lift an SUV? Check out the ninth engine test video. Unfortunately, 12 seconds into the burn an engine failure occurred.

Currently, it is believed the failure was caused due to an injector failure. It is hypothesised that the injector overheated due to an instability causing an increase in Oxidiser mass flow, which led to the chamber wall overheating and finally failing. A low and high-frequency oscillation event has been seen in the data and research to minimise these oscillations is being conducted. Our engineers are working hard on a forensic analysis to discover the cause and find a solution.

Due to our thorough safety procedures, no personnel were here harmed, however, one pumpkin was never seen again.
