一种采用压缩空气弹射的冷发射系统研究

Research on a Cold Launch System with Compressed Air Ejection

针对库区火源隐患应急处置需求,设计了一种可搭载于库区防控无人机(Unmanned Aerial Vehicle,UAV)上的冷发射装置。以压缩空气为冷发射动力源,运用数学建模和结构分析的方法设计了冷发射系统发射管、直型弹夹、储气室的压力调节装置,并探寻了储气室、电磁阀和气瓶尺寸对弹射速度的影响因素,在仅控制电磁阀开关的情况下完成装置的地面射击试验。结果表明:地面射击距纸靶10~35 m时均能命中,且无故障发生。该冷发射装置设计合理,精度较高,能满足进一步的库区防控处置要求。

According to the needs of emergency disposal of hidden fire sources in the reservoir area,a cold launcher which can be carried on the Unmanned Aerial Vehicle(UAV)for prevention and control in the reservoir area is designed.With compressed air as the power source for cold launch system,a pressure regulating device for the launch tube,straight cartridge clip and gas storage chamber of the cold launch system is designed by using mathematical modeling and structural analysis methods,and the influence factors of the size of gas storage chamber,solenoid valve and cylinder on ejection velocity are explored.The ground firing test of the device is completed with only solenoid valve on/off control.The results show that the paper target can be hit at the distance of 10 m to 35 m,and no fault occurs.The cold launcher has reasonable design and high precision,which can meet the requirements of further emergency treatment in the reservoir area.
