〔産業上の利用分野〕
本発明は人工衛星または宇宙飛行体の帯電を中和する方
法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for neutralizing electrical charges on an artificial satellite or spacecraft.
宇宙空間を飛行する人工衛星や宇宙飛行体は、長時間太

載機器や素子を破壊または劣化させたり、誤動作させた
りする。Artificial satellites and space vehicles flying in outer space are charged with positive potential due to photoelectrons ejecting from the surface of parts that are exposed to sunlight for long periods of time, or charged with various charged particles in outer space that adhere to them. do. The voltage of static electricity caused by charging can reach anywhere from a single volt to several hundreds of thousands of volts, which can discharge and destroy or deteriorate installed equipment and elements, or cause them to malfunction.
従来、人工衛星または宇宙飛行体の帯電を中和する有効
な手段はなく、せいぜい各部の導電性を良くして帯電を
なるべく防止しようとする消極的手法がとられているK
すぎなかった。Until now, there has been no effective means to neutralize static electricity on artificial satellites or spacecraft, and passive methods have been taken to prevent static electricity as much as possible by improving the conductivity of each part.
It wasn't too much.
上述した従来の方法は、効果が不充分で、前述した放電

ことが多く、これらの表面を、それぞれの素材の特性を
損なわないで完全に導体化することは非常に難しい。The above-mentioned conventional methods have the disadvantage that they are insufficiently effective and cannot prevent the above-mentioned discharge. In particular, the surfaces of artificial satellites and spacecraft are often covered with insulating materials such as metal-deposited plastic sheets, tiles, and quartz cover glass for thermal control, and these surfaces can be completely covered without impairing the characteristics of each material. It is very difficult to make it into a conductor.
本発明の帯電中和方法は、人工衛星または宇宙飛行体の
帯電部分に帯’m′Bs、位と逆極性の荷電粒子を与え
