摘要
身管武器均有减小后坐力和提高机动性的需求,相对其他平台武器,无人机载武器对减小武器后坐力的需求更为迫切。为减少无人机载小口径武器发射的后坐冲量,提出前置喷管-膛口制退器复合减后坐方案,通过内弹道装药设计,建立了复合减后坐发射系统的一维内弹道和后效期的数学模型,并进行了后坐力数值仿真;通过参数匹配提高了喷管与膛口制退器对后坐力的抑制效果。结果表明:提出的复合减后坐方案的后坐冲量减小了59.96%,可为小口径武器前置喷管-膛口制退器复合减后坐研究提供理论支撑。
There is a demand for reducing recoil and improving maneuverability for barrel weapons.Compared to other platform weapons,unmanned aerial weapons have a more urgent need to reduce weapon recoil.To reduce the recoil impulse of small caliber unmanned aerial vehicle(UAV)weapon launch,a composite recoil reduction scheme consisting of a front nozzle and a muzzle brake is proposed.Through the design of internal ballistic charges,a one-dimensional mathematical model of the composite recoil reduction launch system is established,along with numerical simulation of the recoil force.The suppression effect of recoil by the nozzle and muzzle brake has been improved through parameter matching.The results show that the recoil impulse is reduced 59.96%by the proposed composite recoil reduction scheme,which provide theoretical support for the research on recoil reduction for small caliber weapons using front nozzle muzzle brake composite recoil buffers.
