To control a path through which a lightning current flows in a case of a lightning strike by adjusting a charge quantity on an aircraft surface, and thus to save the trouble for repair in the case of the lightning strike.SOLUTION: A thunderstroke control part 3 of a lightning current controller 2 consists of a first electrification part 4 composed of a dielectric which is positively electrified, and a second electrification part 5 composed of a dielectric which is negatively electrified. A positive thunderbolt of thunderbolts causes positive ions etc., to move, and a negative thunderbolt causes electrons, negative ions etc., to move. The first electrification part 4 is positively electrified, and may serve as a thunderstroke part for a negative thunderbolt with high probability. The second electrification part 5, on the other hand, may serve as a thunderstroke part for a negative thunderbolt with high probability. The first electrification part 4 and second electrification part 5 are provided on an aircraft 1 to be exposed to the atmosphere. Consequently, the thunderstroke control part 3 composed of the first and second electrification parts 4, 5 has a higher probability of thunderstroke than a circumferential structure whichever polarity the thunderbolt has.SELECTED DRAWING: Figure 1
【課題】航空機表面における帯電量を調節することで被雷した場合の雷電流が流れる経路を制御し、よって被雷した場合に補修に必要となる労力を低減する。【解決手段】雷電流制御装置2の着雷制御部3は、プラスに帯電する誘電体で構成される第1の帯電部4、およびマイナスに帯電する誘電体で構成される第2の帯電部5で構成される。又雷の内、正極性雷は、正イオン等が移動する雷であり、負極性雷は、電子や負イオン等が移動する雷である。第1の帯電部4は、プラスに帯電するので負極性の雷の着雷位置となる確率が高い。逆に、第2の帯電部5は、正極性の雷の着雷位置となる確率が高い。第1の帯電部4及び第2の帯電部5は、大気に露出して航空機1に設けられる。これにより、雷の極性が正負何れであっても第1、第2の帯電部4、5で構成される着雷制御部3への着雷確率を周囲の構造体よりも増加させられる。【選択図】図1
