Description

TECHNICAL FIELD

[0001] The present application belongs to the field of cruise missile wing folding and unfolding mechanism, in particular to an electromagnet locking type cruise missile wing folding and unfolding mechanism. BACKGROUND

[0002] With the acceleration of modern war rhythm, the frequent local war and the replacement of intelligent weapons, cruise missiles play the combat effect of "1+1>2", and have become the main killing tool of high-tech war, playing an increasingly important role. At the same time, the requirement of "swarm of unmanned aerial vehicles" for the number of cruise missiles, the requirement of multi-platform launch for folding storage, and the limitation of carrying energy on battlefield survival time all put forward higher performance requirements on cruise missiles, requiring more reliable layout scheme and more excellent aerodynamic shape to improve the cruise time and battlefield survival rate of cruise missiles.

[0003] Box launching gradually becomes a mainstream trend of cruise missile launching, which can greatly reduce the storage space and increase the number of simultaneous launching, meeting the requirements of swarm combat. After the cruise missile is loaded into the launching box, the front and rear wings and the vertical tail are unfolded and locked. Whether the wings can be normally unfolded or the unfolding time is greatly different from the designed time plays a decisive role in the success of launching.

[0004] The commonly used wing unfolding method is to simultaneously and quickly unfold the left and right folded wings, and then complete the locking in a straight line. In the existing locking mechanisms, spring pins are used for locking, hooks are used for locking, and electromagnet studs are used for locking. The elastic force mechanisms all use springs or torsional springs. Among them, the spring pin locking has the problem of inaccurate positioning of folding and unfolding, and the risk coefficient of normal unfolding is large. The hook locking and the stud locking all have the same problem, that is, they cannot meet the requirement of keeping the left and right positions of the wings unchanged during flight to complete complete locking, and there is a tendency for the wings to tilt to one side or both sides, resulting in changes in the shape of the cruise missile during flight, poor wind speed change resistance, unstable flight and poor overall performance.

[0011] The left wing root rotating part and the right wing root rotating part are provided with an electromagnet locking hole, which is used as a locking hole in the unfolded position and also used as a locking hole in the folded position;

[0012] Four electromagnets are arranged in the wing box, and the four electromagnets are used in pairs, wherein the center distance of the outer two electromagnets is greater than the center distance of the other two inner electromagnets, the outer two electromagnets are inserted into the electromagnet locking holes of the left wing root rotating part and the right wing root rotating part when being powered off, the left wing root rotating part and the right wing root rotating part are locked in the folded position, and the outer two electromagnets are separated from the electromagnet locking holes when being powered on, and the left wing root rotating part and the right wing root rotating part are unlocked in the folded position; the inner two electromagnets are inserted into the electromagnet locking holes of the left wing root rotating part and the right wing root rotating part when being powered off, the left wing root rotating part and the right wing root rotating part are locked in the unfolded position, and the inner two electromagnets are separated from the electromagnet locking holes when being powered on, and the left wing root rotating part and the right wing root rotating part are unlocked in the unfolded position.
