摘要:
通过地面试验模拟了某深空撞击器侵彻天体过程,并得到侵彻过程有关数据。试验采用125 mm口径滑膛炮作为撞击器发射平台,浇筑C20圆柱形素混凝土靶标,发射撞击器撞击靶标,得到了撞击器在不同速度下的侵彻深度、受损情况及过载数据。试验结果表明:以125 mm口径滑膛炮作为发射平台合理有效; 撞击器在着靶速度662 m/s以上时能达到1 m以上侵彻深度,同时满足强度要求。
Abstract:
The penetration process of a deep space impactor into celestial bodies is simulated through ground tests,and the relevant data of the penetration process are obtained. A 125 mm sliding gun is used as the launching platform of the impactor,a C20 cylindrical plain concrete target is poured,and the impactor is launched against the target. The penetration depth,damage and overload data of the impactor at different velocities are obtained. The test results show that it is reasonable and effective to use the 125 mm sliding gun as launching platform. The penetration depth of the impactor reaches more than 1 m when the impact velocity is 662 m/s,and meets the strength requirements.
