Abstract

The invention discloses a lightning test device for simulating a dynamic aircraft, comprising wind tunnel test equipment, aircraft scale model, support column, support platform, high-voltage electrode, lightning generator, high-speed camera and support frame, and the aircraft scale model is installed on On the support column, the support column is fixed on the support platform and placed at the air outlet of the wind tunnel test equipment. The wind tunnel test equipment blows air to the scale model of the aircraft to simulate the dynamic flight of the aircraft. At the same time, various types of lightning generated by the lightning generator The electric current discharges to the scale model of the aircraft through the high-voltage electrodes connected to it to simulate lightning strikes, and the high-speed camera records the dynamic lightning strike attachment process. The invention can realize the lightning strike test of the aircraft under the simulated dynamic flight mode, has a reasonable design, satisfies the simulated dynamic test requirements of the lightning partition test including the supersonic aircraft, avoids the error of the static test, and the measured data is closer to the real Happening.

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...
