摘　　要：深空撞击器可侵入目标天体表面以下一定深度进行有关探测。文中根据动能侵彻弹相关设计理论,设计了一种深空撞击器结构。采用滑膛炮作为发射平台,对其侵彻混凝土过程进行了试验。试验结果表明,所设计撞击器在初速度为662~819 m/s之间时,均能达到侵彻深度1 m以上,且结构强度满足性能要求,最后通过数值仿真与试验结果进行了互证。试验所得过载数据为撞击器内部有效载荷设计提供了参考。The deep space impactor can invade into a certain depth below the surface of the target celestial body for detection.In this article,based on the design theory of kinetic energy penetrating projectile,the deep space impactor is developed.The sliding gun is adopted as the launching platform,and the test is conducted on the process of concrete penetrating.The results show that this impactor can reach the penetration depth of more than 1 m with an initial velocity between 662 m/s and 819 m/s,and the structural strength meets the performance requirements.The data on overload obtained from the test provides reference for the design of the deep space impactor’s internal payload.
