摘要:
根据双钟型喷管高度补偿特点及技术研究现状，提出了一种双钟型喷管液氧甲烷发动机系统方案，进行了双钟型喷管基弧段及延伸段面积比优化，并与其他系统方案进行了性能对比分析。研究表明，对于地面起动的芯级发动机，采用双钟型喷管是提高发动机综合比冲性能以及运载器有效载荷的有效途径。
Abstract:
A system scheme of LOX/methane rocket engine with dual-bell nozzle is presented based on altitude compensation features and development status of dual-bell nozzle. The aero ratio of basic arc section and stretching section of the dual-bell nozzle was optimized. Its performance was compared with other system schemes. The result shows that, as for the core engine launched on ground, the application of the dual-bell nozzle is an effective way of improving the engine comprehensive specific impulse and payload of launch vehicle.
