| This paper introduces the styles, functions and current research of aeronautic missile ejecting device. The structure, principle of blank cartridge ejecting device and its differentia are discussed in detail. Because of its extensive application and underdeveloped research level in our country, this paper establish the numerical model of blank cartridge ejecting device, the whole process from blank cartridge burning to eject missile is analyzed by classic interior ballistic theory and gas dynamics. Several simulation examples are given, and the effect of different parameter structure on ejecting device is discussed. Based on existing types, simulation design is carried outfor the first time. The simulation and optimization results show that all types can be improved in considerable degree. Accessorial software can execute all required functions for compute added design. |
