| Abstract: |
| Objective In order to design grain sustaining plate structure of free filling grain solid rocket motor (SRM) with canted nozzle suitable for large flow. Methods The new two-way orthogonal sustaining plate sprayed thermal barrier coating was proposed based on contrastive analysis of sustaining plate structure for free filling grain. Structure parameters of the sustaining plate were optimized through simulating calculation and the 4 designing schemes were verified and analyzed through ignition experiments of engine. Results The 8-8 two-way orthorhombic sustaining plate sprayed with thermal barrier coating had large breathing area, high structural strength and ablation resistance. It met the requirement of using the engine. Conclusion The new two-way orthogonal sustaining plate sprayed with thermal barrier coating can provide strong structure strength as well as better thermal ablation. |
