How do conventional rockets work?
Hydrazine is a family of compounds that are used in the rocket industry as monopropellants.
|Unsymmetrical dimethyl hydrazine (UDMH)||CH3NNH2|
It is used as a monopropellant because hydrazine will decompose (ignite) when placed in contact with platinum group metal catatlysts. Hydrazine is popular with satellite builders because the monopropellant properties save space, complexity, and weight. It saves space because there is no need to carry up a separate oxidizer. It saves weight and simplifies the system because there is only one set of plumbing and no ignition system.
