【摘要】 晴天下的直升机与周围大气中粒了发生撞击的几率甚微,因此可忽略其对直升机荷电的影响,其荷电主要受发动机喷流中带电粒子的影响.本文在对晴天下直升机荷电进行分析的基础上,提出了一种对其荷电电压和电流进行测量的方案,推导出了直升机的荷电方程,并对其进行了初步讨论,最后得出了晴天下直升机的荷电等效电路,从而为进一步研究直升机的荷电提供理论基础.更多还原

【Abstract】 Particles in the air have little chance to collide with helicopter in the fair-weather.Their impact onthe helicopter may be ignored.In this case,the particles in the jet stream will generate electrostatic charge onthe helicopter.Basing on the analysis of charging helicopter in the fair-weather,a frame is introduced tomeasure the voltage and current of the charging helicopter in this paper.The equation of the charginghelicopter is deduced.Then the equation according to the practical situation is discussed preliminarily.Finally the equivalent circuit of the charging helicopter in the fair-weather is obtained.These will offer atheoretic basis to study the helicopter charging mechanism in different weather.更多还原
