Solid propellant combustion in a high-velocity cross-flow of gases (review)

详细

Combustion of solid propellants in rocket propulsion systems usually occurs in an intense cross-flow of combustion products (solid rocket motor), gaseous oxidizer (hybrid rocket motor) or air (ramjet and air-breathing engines). This leads to the so-called erosive burning effects, resulting in a change in the burning law under the influence of the gas flow. The main approaches to modeling the erosive burning of solid propellants in a high-velocity cross-flow of gases are considered. Methods for the criterial description of the results of experimental studies of the erosive burning of solid propellants under transonic and supersonic flow conditions are analyzed.
