摘要
研究了固定翼飞机静电分布特性及电容求解.首先详细论述了固定翼飞机空中飞行时的静电产生机理.使用矩量法分别求取了飞机空中飞行、停靠地面时的电荷分布;获得了2种不同状态下的飞机电容:某型飞机空中飞行时电容为400 pF,停靠地面时为1.3 nF,从而获得了飞机着陆时的放电时间常数.电荷分布计算结果与理论分析吻合,电容值与美军标Mil-Std-464给定数值一致,说明了计算的正确性.
This paper investigate characteristic of electrostatic charge distribution and capacitance solving of fixed wing aircraft. Firstly, the mechanism of electrostatic origin of fixed wing aircraft flying in the sky is discussed in detail. The charge distribution and capacity are calculated by moment method when aircraft fly in sky and anchor on the ground, respectively. The capacity of certain type of aircraft is 400 pF and 1.3 nF, respec- tively. And based on capacity, the time constant of electrostatic discharge when aircraft lands on the ground is calculated. The charge distribution by calculating numerically is consistent with analyzing theoretically. And the capacity of aircraft is consistent with Mil-Std-464 as well. It proves that the calculating process and results are correct.
