Lightning effect test device for dynamic airplane

Abstract

The invention discloses a lightning effect test device for a dynamic airplane. A computer in the device is arranged outside a microwave dark room; a round turntable A, a round turntable B, an airplane scale model, a lightning generator, a spectrum recorder, a support platform and a camera are arranged in the microwave dark room; the camera is mounted on the support platform; the airplane scale model is mounted on the round turntable A; the spectrum recorder is mounted on or in the airplane scale model; and the lightning generator is mounted on the round turntable B. When the round turntable A and the round turntable B rotate relatively, various types of lightning analogue currents and electromagnetic waves generated by the lightning generator act on the airplane scale model; and when the lightning happens, the spectrum recorder records the lightning indirect effect, and the camera records the lightning direct effect. According to the invention, the process that the airplane in dynamic flying mode encounters lightning can be simulated in the limited space of the microwave dark room so that the tested data approaches to the real conditions better and the error is reduced.

Description

technical field [0001] The invention relates to a dynamic aircraft lightning effect test device, more particularly, a dynamic aircraft lightning effect test device for simulating the process of an aircraft encountering a lightning strike in a dynamic flight mode under the condition of a limited space in a microwave anechoic chamber. Background technique [0002] Lightning is one of the most serious natural disasters that threaten human beings. The impact of lightning on aircraft is divided into direct effects of lightning and indirect effects of lightning. The direct effect of lightning refers to the effects of burning, corrosion, and structural distortion caused by high-temperature, high-voltage shock waves and electromagnetic forces on the aircraft when the lightning arc is attached to the surface of the aircraft; the indirect effect of lightning refers to the strong electromagnetic The impact of pulse on personnel and fuel safety and the interference or damage caused by ...

AI Technical Summary

Problems solved by technology

Accurate experimental data can be obtained in the flight experiment of the aircraft passing through the thunderstorm area, but the experiment cost is expensive, and the test period is longer because it needs to find the thunderstorm area for multiple test flights
