WARR 10kN Engine Test

From Facebook

Hard work pays off!
On Friday we successfully fired our 10kN engine for 5 seconds. The system performed as planned as we nearly hit the nominal operation point. We are now looking forward to testing for the full burn time of 15 seconds next week.

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.

Backyard Hybrid Rockets

Abit of a tweet storm from me, but this is one project worth showcasing.

Jonny Hyman has over the past few months been working to develop his own hybrid rocket propulsion system. Not only has he been developing the engine but also all the necessary ground support equipment required which is just as impressive as the engine itself.

Jonny has produced an impressive engine monitoring system, from the GUI to the camera system set up in his backyard. The engine is expected to produce 40N of thrust, able to be throttled and will have fast restart times.

You can follow Jonny on Twitter (most updates here) or check out his website and Instagram pages.

DHX-400 ‘Nimbus’ Hybrid Rocket Motor Test #5

The students of Delft Aerospace Rocket Engineering have been hard at it, having completed this recent test. The motor is designed to produce a nominal thrust of 15kN and burn for 28sec.
