[0049] see figure 1 , the simulated aircraft bus voltage waveform diagram shows the bus voltage change process in the aircraft workflow. The bus voltage waveform diagram can be obtained through the real ignition test of the aircraft, and can also be calculated according to the instantaneous current value of the pyrotechnic device ignition. Voltage waveform diagram. figure 1 The middle 28.5V is the normal power supply voltage of the aircraft bus bar, the voltages V1 and V2 are the instantaneous voltage of the bus bar when the pyrotechnic device is ignited, and the ignition current of different pyrotechnic devices is also different. During the actual launch process of the aircraft's electrical network test, different pyrotechnic ignition processes occurred at 0 (aircraft launch time), t1, t2, t3+2, and t4, resulting in multiple voltage drops. . The invention checks whether each component of the aircraft can work normally by simulating the real-time change of the bus bar voltag...
