- 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.
