| 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. |
