Lightning test device for simulating dynamic aircraft

Abstract

The invention discloses a lightning test device for simulating a dynamic aircraft, which comprises wind tunnel test equipment, an aircraft scaling model, a support column, a support table, a high-voltage electrode, a lightning generator, a high-speed camera and a support frame, and is characterized in that the aircraft scaling model is mounted on the support column, and the support column is fixed on the support table and placed at an air outlet of the wind tunnel test equipment; and the wind tunnel test equipment blows air to the aircraft scaling model to simulate dynamic flight of the aircraft, meanwhile, various types of lightning currents generated by the lightning generator discharge to the aircraft scaling model through the high-voltage electrode connected with the lightning generator to simulate lightning stroke, and the high-speed camera records the dynamic lightning stroke attachment process. According to the invention, the lightning stroke test of the aircraft in the simulated dynamic flight mode can be realized, the design is reasonable, the simulated dynamic test requirements of the lightning subarea test of the aircraft with the ultra-high sound speed are met, the error of the static test is avoided, and the measured data is closer to the real situation.

Description

technical field

[0001] The invention relates to an aircraft lightning test device, in particular to a device for blowing air on a scaled model of an aircraft using wind tunnel equipment, using the relative movement of the blowing airflow to simulate the dynamic flight of the aircraft, and at the same time, a high-voltage electrode is used to discharge the scaled model of the aircraft. A lightning test device for a simulated dynamic aircraft that simulates a lightning strike. Background technique

[0002] Lightning is an unavoidable natural phenomenon that directly affects flight safety. Statistical data show that after civil aviation aircraft implement strict regulations on circumnavigating thunderstorm clouds and grounding in thunderstorm weather, on average, each aircraft still encounters at least one lightning strike per year. Lightning strikes to aircraft are unpredictable and inevitable. When lightning attaches to the surface of the aircraft, the lightning current can...
