Model Describing the Erosive Combustion and Velocity Response of Composite Propellants

摘要: A detailed model is presented which permits one to represent the response of burning rate an ammonium perchlorate solid composite propellant pressure and velocity fluctuations. First, steady regime a exposed turbulent boundary layer described. The well-known granular diffusion flame employed, with changes in transport coefficients taken into account. It shown (and not assumed) that, according present model, additive law applies; sensitive erosive component added normal rate. By coupling unsteady behavior phase quasisteady zone, represented by abovementioned linearized oscillations obtained.
