摘要
提出了一种低成本、简易锚钩发射装置设计方案.该方案采用一种新的击发方式,以高压气体为能源,经大小气腔压力差作用使活塞杆后坐,完成击发.数值计算了身管长度、气腔容积与初速之间的变化关系,对身管和气室进行了静力学仿真分析.结果表明,身管长度、气腔容积与初速之间成正相关,身管和气室的最大变形量、最小安全因子均满足要求,膛口初速可达 43.4 m/s,能满足极端条件下海上救援、攀爬引缆的功能,且大幅减轻了锚钩发射装置的质量,便于单兵作战.
Abstract
A low-cost and simple anchor hook launch device design scheme has been proposed.This scheme adopts a new firing method,which uses high-pressure gas as the energy source and causes the piston rod to recoil through the pressure difference between the large and small gas chambers,completing the firing.The relationship between the length of the barrel,the volume of the air chamber,and the initial velocity was numerically calculated,and static simulation analysis was conducted on the barrel and the air chamber.The results show that there is a positive correlation between the length of the barrel,the volume of the air chamber,and the initial velocity.The maximum deformation and minimum safety factor of the barrel and air chamber meet the requirements.The initial velocity of the muzzle can reach 43.4 m/s,which can meet the functions of maritime rescue and cable climbing under extreme conditions.Moreover,it greatly reduces the weight of the anchor hook launch device and facilitates individual combat.
