The invention solves the problem that the existing aircraft wings cannot adapt to the requirements of complex aerodynamic environments. It includes motor, lead screw, first to fourth skin structures, the fourth skin structure is nested in the third skin structure, the third skin structure is nested in the second skin structure, the second skin structure The structure is nested in the first skin structure, and the two adjacent skin structures are slidingly connected, the motor is fixed in the first skin structure, and the lead screw is fixed along the sliding direction of the second skin structure At the output end of the motor, each of the second to fourth skin structures is fixed with a positioning seat, and each positioning seat is processed with an internal thread hole that matches the lead screw, and the three internal thread holes are coaxial with the lead screw. set up. The invention is used for the wing structures of various deformable aircrafts.

Description

technical field [0001] The invention relates to a multi-stage retractable wing mechanism, which belongs to the technical field of aerospace equipment and equipment. Background technique [0002] In aircraft design, in order to meet the requirements of supersonic flight drag reduction, wings with large backsweep and small aspect ratio are generally used, and to obtain good take-off and landing performance, low-speed maneuverability and long-distance flight time requires wings to have The characteristics of small backsweep and large aspect ratio contradict the requirements of supersonic drag reduction. As the application of aircraft in the military and civilian fields becomes more and more complex, there is an urgent need for a device that can have a larger flight airspace and speed range, can take into account high and low altitudes, high and low speeds, and even take off from the ground and fly through the atmosphere to perform various tasks. Aircraft for complex tasks such...
