BRISTOL AEROSPACE PRESS UPDATE
Bristol Spaceplanes has carried out a strapdown test firing of the HPD (Hydrogen Peroxide Demonstrator) sounding rocket that will be used to test in flight a development version of the Ascender rocket engine.
The test was entirely successful. The engine is based on UK heritage technology and the production version uses hydrogen peroxide and kerosene as the propellants. The test engine is a development version that uses hydrogen peroxide only. The exhaust products are steam and oxygen, which is why there is no flame. A nose cone and fin will be added before the HPD rocket will be launched.
