The technology of explosive cutting aircraft skin formed emergency exit was used in emergency evacuation of aircraft to save the time of evacuation. The feasibility of formed emergency exit through explosive cutting aircraft skin and fuselage frame in higher flight altitude was analyzed from the rapid decompression, construct distortion, construct intension and reverse impact of explosive to aircraft. Because of the exising of frame and rib, the linear shaped charge (LSC) must bend to round this construct which will reduce the cutting effects of LSC. In order to validate this phenomenon, plenty of experiment were carried out. The test result show that if the distance between the curving LSC and frame was controlled in 2 mm and 8 mm, and the distance between the curving LSC and rib was less than 2 mm, the request of cutting skin and frame can be satisfied. There is no interference between the curving LSC which round the frame and rib. The feasibility of explosive cutting aircraft skin formed emergency exit was proved by the full scale test of ground.
