Abstract :
The thermal structure characteristic of the Solid Rocket Motor (SRM) nozzle component under thermal and flow field is investigated by finite element method (FEM). The sensitivity of contact parameter of friction coefficient between multi-layer structures on thermo-structure coupled simulation is priority analyzed and the individual test of the friction coefficient between real material of carbon/carbon material and molded asbestos/phenolic material with temperature under real work condition is also designed. The numerical results and the experimental conclusions can provide some important value to the reliability design of nozzle thermal structure.
