Submerged folding wing synchronous lateral unfolding locking mechanism and unfolding locking method thereof

Abstract

The invention discloses a submerged folding wing synchronous lateral unfolding locking mechanism and an unfolding locking method thereof. Existing airfoil folding and unfolding locking mechanisms areexposed outside projectiles in the folded state, the overall aerodynamic performance of missiles is affected in the folded state, and the folding and unfolding process is greatly affected by fluid. The mechanism of the invention comprises a machine frame, folding wings, a spring locking mechanism, a positioning block, a motor, a locking sliding block, a pin shaft, a screw rod, a torsional spring fixing member, a torsional spring, a nut block, a coupling, a spring and a spring pin. The N folding wings are synchronously unlocked by moving the locking sliding block in the axial direction of the screw rod; and the unlocked folding wings are unfolded under the action of the torsional spring, and are locked by the spring locking mechanism after being unfolded in position. The mechanism is storedin a projectile in the folded state, submerged folding of the missile wings is achieved, the aerodynamic performance of the missile is effectively ensured, and the lateral dimension of the missile isreduced.

Description

technical field [0001] The invention belongs to the technical field of aerospace and aviation, and relates to a missile folding wing unfolding and locking mechanism, in particular to a submerged folding wing synchronous lateral unfolding and locking mechanism and an unfolding and locking method thereof. Background technique [0002] Folding wings can reduce the radial size of the missile body, reduce the volume of the launching device, facilitate storage, transportation and launching in the launch box or launch tube, increase the carrying capacity of vehicles or ships, and improve the combat capability of weapons and equipment. The function of the folding wing unfolding locking mechanism is to make the wing surface fold before launching, and automatically unfold and lock reliably under the action of driving force after launching. Most of the wing surface folding and unfolding locking mechanisms currently used are exposed outside the projectile body in the folded state, and t...

AI Technical Summary

Problems solved by technology

Most of the wing surface folding and unfolding locking mechanisms currently used are exposed outside the projectile body in the folded state, and the overall aerodynamic performance of the missile will be affected to a certain extent in the folded state, reducing the flight stability of the missile; The folding and unfolding mechanism exposed outside the projectile body is greatly affected by the fluid during the folding and unfolding process, which directly affects the unfolding and locking process
