Abstract

The invention discloses a novel variable-sweep wing mechanism, which includes a cover plate, a base, a push block, and a spring locking pin. The sweep angle of the wing is controlled by the push block and locked by motor control; Cooperating with the spring locking pin, the cover plate and the base can be unlocked and locked when the sweep angle changes, ensuring the matching between the center of mass and the pressure center of the full spring during the change of the sweep angle, optimizing the resistance and moment characteristics of the full spring, and improving Full bombardment control efficiency.

Description

technical field

[0001] The invention belongs to the technical field of variable-sweep wing missiles, in particular to a novel variable-sweep wing mechanism. Background technique

[0002] Most of the structural forms of the range-extending components of existing missiles are fixed sweep angles. The actual application shows that the variable-sweep wing missile has strong maneuverability and good adaptability to the flight environment. It can reduce the wing sweep angle by changing the wing sweep angle when flying across subsonic / transonic / supersonic speeds. Flight resistance, improve the flight stability of the missile, and increase the attack range of the missile. In terms of performance, variable-sweep wing missiles are superior to fixed-sweep wing missiles in performance.

[0003] At present, domestic variable-sweep wing mechanisms are relatively complex, and the efficiency of production and assembly is not high. Moreover, changes in the sweep angle will cause changes in ...
