The invention belongs to the spaceflight environment intensity technology field, to be specific, relates to a combustible gas loading dynamic impact test device comprising a gas outlet, an explosion diaphragm, an igniter, a combustible gas cavity, a pressure sensor, and a gas inlet valve. The center of the upper part of the combustible gas cavity is the annular boss, the upper part of which is provided with the gas outlet communicated with the combustible gas cavity. The explosion diaphragm is disposed in the boss along the cross section, and the combustible gas cavity is respectively provided with the pressure sensor and the igniter. The side surface of the combustible gas cavity is provided with the gas inlet valve, and a test piece is disposed on the bottom part of the combustible gas cavity. The combustible gas loading dynamic impact test device is advantageous in that the uniformly-distributed impact loads applied on the pneumatic impact load or structure can be simulated, and the dynamic impact loading
