Coupled Fluid, Thermal and Structural Analysis of Nozzle in Solid Rocket Motor

Abstract:

A coupled fluid, thermal and structure analysis model was established for solid rocket motor nozzle. Based on a steady flow simulation and a transient thermal simulation, a transient structure analysis simulation was executed. The model took a frictional coefficient 0.3 into account to simulate a rub action between the parts of the nozzle. Result showed that with a frictional coefficient, Von Mises stress could be released which gives a constructive recommendation for a structure simulation of a nozzle. Also, the model was more close to the actual. A more dependable approach was introduced and it could contribute to designing department.
