为了掌握超高速碰撞产生等离子体对航天器上常用典型逻辑芯片产生的干扰,利用自主设计的朗缪尔三探针诊断系统,进行了弹丸(入射速度为6.10 km/s,入射角度为30°)超高速碰撞2024-T4铝产生等离子体的特征参量诊断,测量了给定位置和方位角处等离子体的电子密度,利用数据采集系统对实验给定位置和方位角处逻辑芯片的干扰情况进行了评价.实验结果表明,超高速碰撞产生的等离子体对航天器上常用的逻辑芯片将产生严重干扰.%To acquire the interference status of typical logic chips in spacecraft caused by plasma generated from a hypervelocity impact,the triple Langmuir probe system established by selfishness is used for diagnostics of plasma characteristic parameters created by 2024-T4 aluminum projectile hypervelocity impact on 2024-T4 aluminum target,with the impact velocity and incidence angle of 6. 10 km/s and 30°,respectively. The plasma electron density is measured at a given position with a given azimuth,and the interference estimation is performed for logic chip by data acquisition system. The experimental results show that the logic chips in spacecraft will be seriously influenced by plasma generated at hypervelocity impact.
