Combustion and detonation characteristics of hydrazine and its methyl derivatives

The basic gas-dynamic characteristics of the detonation, instantaneous combustion (explosion) in constant volume, combustion at constant pressure, and deflagration for hydrazine, methylhydrazine, 1,1- and 1,2-dimethylhydrazine, and trimethylhydrazine in mixtures with oxygen or air that are diluted with argon at varied initial pressure and temperature values are given. The main parameters of these processes are analyzed both for the case of a gaseous propellant and for the case of a heterogeneous propellant where the propellant is a highly disperse, sprayed cloud in an oxidant medium. Calculations were performed by means of the computer code SAFETY. Calculation results are in agreement with correct experimental data.
