Estimation of the efficiency of gas dynamic protection of the SPRM casing body with an internal-external burning combined charge
The problem of gas dynamic protection of thebody of a solid propellant rocket engine with a set-in sequential multigrain charge is considered.For this purpose, the main grain is made as a coaxial cylinder with an outer cylinder made of fuelcomposition with significantly lower burning temperature. Low-temperature fuel combustionproducts form a gas-screen along the inner surface of combustion chamber serving as a thermalprotection. The inter-grain retainer pad structure provides steady motion of the gas-screen. Resultsof numerical analysis of efficiency of the selected method of thermal protection of the model enginebody for the 2D gas dynamic scenario are given.
