DARE Test Composite Chamber Stratos IV Engine

The test was the first for the carbon fibre chamber, saving much-needed weight will enable Stratos IV to fly even higher!

CU Space Flight Test the UK’s Largest Impulse N2O Rocket Engine

Students of Cambridge University Space Flight have recently tested the UK’s largest impulse Nitrous Oxide-fueled rocket engine. The engine burnt nitrous oxide and High-Density Polyethylene (HDPE), burning for 36 seconds and producing 1496 N of thrust. The engine is intended to power the team’s Marlet 4 rocket, set to launch in 2020 in the hopes of breaking the UK Amateur Rocketry Altitude Record.

Founded in 2006, CUSF have grown to become leaders in amateur rocketry and high altitude ballooning. contact@cusf.co.uk

WARR: Cryosphere – Frigate Test 9 and 10

Video Caption: After several enhancements on our subscale engine, we lit it twice on the first of July. We hit the design point of the engine and collected valuable scientific data.
The now purely axial injection smoothens our combustion, just as predicted. Being able to safely predict the system behaviour is what we perceive to be the key to continue the development of successively larger engines.

More good news: The first hotfire test of the fullscale engine has now preliminarily been fixed to November this year – stay tuned!

Technical Data:
Mean thrust: ~1600 N
Chamber pressure: 20 bar
Burn time: 5 s
Mass flow oxygen: 550 g/s

Please note: We’re predominantly master students of mechanical engineering and spend most of the time before test on calculations and preparations to prevent severe damages on material and personnel. Please don’t feel inspired to light your own rocket motor in your backyard. Rocket science is a serious issue – if you get the numbers wrong, people die.
