摘要
为了研究固定翼飞机静电分布特性及着陆时静电泄放,在论述了固定翼飞机空中飞行时的静电产生机理、飞机静电的消散形式后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;获得了飞机着陆时的放电时间常数及某型飞机2种不同状态下的飞机电容:空中飞行时400pF,停靠地面时1.3nF。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,说明计算正确。最后根据静电放电的脉冲特性,建立了着陆时的静电放电的传输线电路模型,通过分析模型,给出了着陆时高阻的安全放置位置。
This paper investigates characteristic of electrostatic charge distribution and electrostatic landing discharge of fixed wing aircraft. Firstly, the mechanism of electrostatic origin and dissipation 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 capacitance of certain type of aircraft is 400pF and 1.3nF, respectively. And based on capacitance, the time constant of electrostatic discharge when aircraft lands on the ground is calculated. The charge distribution by calculation numerically is consistent with analysis theoretically. And the capacitance of aircraft is consistent with Mil-Std-464 as well. It proves that the calculating process and results are correct. Giving the pulse characteristic of electrostatic discharge, the circuit model of transmission line of electrostatic discharge when the aircraft land is constructed. By analyzing the model, the safety position of high resistance is presented.
