The invention belongs to the field of underwater recovery, and particularly relates to an air bag type tail cover recovery device which comprises a pressure-resistant shell, an air bag and a high-pressure air cylinder, the pressure-resistant shell is in a convex shape with the front face and the rear face directly communicated, the recovery device further comprises a three-channel valve body and a trigger assembly, and the trigger assembly comprises a firing pin, a trigger block, a push rod, a guide sleeve, a disc spring and a locking nut. The firing pin is slidably connected into a right channel of the three-channel valve body, an outlet of the right channel is sealed, the tip end of the firing pin abuts against a bottle opening of the compressed air bottle, the right end of the firing pin is connected with a trigger block, the right end of the trigger block is connected with a push rod, and the right end of the push rod is connected with a disc spring. The disc spring is fixed to the inner wall of the right side of the convex pressure-resistant shell through a locking nut. The recovery device does not need a power pack and a control unit, is simple in structure and low in cost, can effectively reduce the technical risk in the water entry process, realizes the recovery and utilization of the tail cover, and ensures the safety of the experimental aircraft.
