Hypergolic rocket engine combustion
A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer. The main advantages of hypergolic propellants are that … Meer weergeven In 1935, Hellmuth Walter discovered that hydrazine hydrate was hypergolic with high-test peroxide of 80-83%. He was probably the first to discover this phenomenon, and set to work developing a fuel. Prof. Otto Lutz … Meer weergeven Common Common hypergolic propellant combinations include: • Aerozine 50 + nitrogen tetroxide (NTO) – widely used … Meer weergeven 1. ^ "-ergol", Oxford English Dictionary Meer weergeven Advantages Hypergolically-fueled rocket engines are usually simple and reliable because they need no ignition system.
