When the nozzle is working, there is large amount of hot gas at the interface of the carbon-carbon(C/C) exit-cone because of the pyrolysis of insulator. The hot gas may cause high pressure which may impact the reliability of the joint structure. So the high temperature and pressure measurement were developed to measure the temperature and pressure at the interface of the C/C exit-cone and the insulator...
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...
