摘要:

太阳电池阵空间放电电弧严重威胁航天器的可靠运行和安全寿命。基于太阳电池阵在空间等离子体环境放电电弧理论,对高能脉冲激光诱导太阳电池阵放电电弧机理进行分析,采用空间放电地面模拟实验系统研究3种不同工况下的太阳电池阵放电电弧特性,得到3种工况下激光诱导放电电弧的功率密度阈值分别约为1.8×108 W/cm2、1.45×108 W/cm2和1.08×108 W/cm2。在近地轨道等离子体环境下每次施加脉冲激光诱导放电电弧的概率达到约60%,且激光诱导放电电弧电流峰值为5.4 A,平均持续时间达到16.68 μs,极易对太阳电池阵造成较大危害。

Abstract:

The discharge arc of solar array seriously threatens the reliable operation and safe life of spacecraft. Based on the discharge arc theory of solar array in space plasma environment, the discharge arc mechanism of high-energy pulse laser-induced solar array was analyzed. The discharge arc characteristics of solar array under three different working conditions were studied by using space discharge ground simulation experiment system. The energy density thresholds of laser-induced discharge arc under three working conditions were obtained, which were about 1.8×108 W/cm2, 1.45×108 W/cm2 and1.08×108 W/cm2, respectively. In the Low-Earth-Orbit plasma environment, the probability of each pulse laser-induced discharge arc is about 60%, and the peak value of the laser-induced discharge arc current is 5.4 A, and the average duration is 16.68 μs, which is very easy to cause great harm to the solar array.

Key words: solar array, laser, plasma, discharge arc characteristics
