The Aero-Thermodynamic Effect Simulation Study of Solid Motor Grain

Abstract:

The long-stored missile as a result of environment temperature stress functions and so on, it will cause the missile material aging. For high-speed flight's missile, thermal coefficient of expansion between the different structural and element will be different simultaneously, when the aerodynamic heating will produce, the grain and the thermal insulation layer will also be appeared the crack phenomenon in the influence of expand with heat and contract with cold rules. For the example of some infra-red missile, aero-thermodynamic effect of the missile is carried on the forecast using the ANSYS software simulation, it has the important meaning to analyze the storage performance and failure mechanism of flying missile and so on.
