The utility model discloses a
hang glider separating and releasing mechanism. The mechanism comprises a hoop which is arranged outside an aircraft body in a sleeving mode and comprises a
left half hoop and a right half hoop, the
left half hoop is connected with a left side
hang glider, and the right half hoop is connected with a right side
hang glider; one ends of the
left half hoop and the right half hoop are fixedly connected, and the other ends of the left half hoop and the right half hoop are inserted and elastically connected through a compressed first-stage separation spring; the
piston cylinder is arranged in the aircraft body and is fixedly connected with the aircraft body; a memory
alloy circular ring capable of being contracted by heating is arranged in the
piston cylinder; a
piston is arranged on the memory
alloy circular ring; a compressed secondary separation spring is arranged on the periphery of the piston; the limiting stud is used for sequentially penetrating through the hoop and the aircraft body to be fixedly connected with the piston; when the memory
alloy circular ring is heated and contracted, the piston drives the limiting stud to move downwards under the action of the second-stage separation spring to release connection between the left half hoop and the right half hoop, and the left half hoop and the right half hoop are opened under the action of the first-stage separation spring to be separated from the aircraft body.
