Device and method for automatically resetting release lock in full-aircraft drop test of carrier-based aircraft

The invention provides a device and a method for automatically resetting a release lock in a full-aircraft drop test of a carrier-based aircraft, and belongs to the technical field of aircraft tests. The device comprises a mounting truss of which the left side and the right side of the bottom end are respectively provided with a supporting leg assembly, an actuating cylinder arranged at the bottom end of the mounting truss, a release lock connected with the bottom end of the actuating cylinder, a spring bolt connected with the release lock, a reset motor arranged on the release lock, and an aircraft test piece connected with the spring bolt through a lifting rope. The movement of the spring bolt can be limited, the spring bolt can be automatically reset, and the locking function of the release lock is completed; the device can effectively protect an airplane, realizes the automation of spring bolt resetting, and improves the test efficiency; by limiting the height of the protection rope, the spring bolt can b
