This rocket engine design is highly dependable and permits throttle control. The XLR-2 was built and designed by Peter Madsen and Kristian von Bengtson. The solid fuel is epoxy resin, a synthetic rubber compound which does not burn by itself, without an oxidizer. The engine is started when a pyrotechnic charge is electrically fired to set off the epoxy, which then only smoulders and is producing no thrust until the nitrous oxide is injected under pressure as a combustion catalyst. The peak chamber pressure here is about 36 atmospheres (~530 PSI). http://www.copenhagensuborbitals.com/ http://images.vimeo.com/16/64/75/166475591/166475591_200.jpg 200 150 2021925
