Bristol Spaceplanes Hydrogen Peroxide Demonstrator Rocket Test

This video is of a test firing of Bristol Spaceplanes' HPD (Hydrogen Peroxide Demonstrator). BSP believes hydrogen peroxide is the best oxidiser for the rocket engines of first-generation spaceplanes such as Ascender. The test, shown in the video, was deemed entirely successful by Bristol Spaceplanes. The engine is based on Britain's heritage technology and the production version uses hydrogen peroxide and kerosene as the propellants. The test engine shown here 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. Credits: Bristol Spaceplanes Ltd.
