A segmented storage wing cover

Abstract

The invention relates to a wing storing cover plate, in particular to a sectional type wing storing cover plate and belongs to the field of aircraft manufacturing. The sectional type wing storing cover plate comprises a wing storing groove cover plate I, a wing storing groove cover plate II, a wing storing groove cover plate III, a missile wing upper cover plate and torsion spring assemblies. One end of the torsion spring assembly is fixed on the missile wing upper cover plate, and the other end of each torsion spring assembly is connected with the wing storing groove cover plate I, the wing storing groove cover plate II and the wing storing groove cover plate III. Each torsion spring assembly comprises a base, a rotary shaft, a torsion spring and a hinge, wherein bent arms extending out of two ends of the torsion spring are respectively clamped in grooves of the base and the hinge, and the rotary shaft is inserted into the torsion spring. Compared with overturning stress of a traditional single cover plate, differential overturning of three cover plates of the sectional type wing storing cover plate is achieved, the cover plates are stressed in the missile wing unfolding process in a sectional mode, and cover plate resistance to missile wings during missile wing unfolding is adjusted by adjusting the number of the torsion spring assemblies on each cover plate. On the premise that the missile wings are smoothly unfolded, the cover plates can overcome pneumatic torque force moment springback after being unfolded, and the dimension effect in the flying process is achieved.

Description

technical field [0001] The invention relates to a wing storage cover, in particular to a segmented wing storage cover, which belongs to the field of aircraft manufacturing. Background technique [0002] In order to meet the requirements of aerodynamic performance and stealth technology of the missile, when the wings are folded, the wing storage covers on both sides must be folded in place, and after launch, the wing storage covers must be able to unfold smoothly with the expansion of the wings, and automatically return after the wings are in place. The spring locks in place to achieve the dimension effect. Due to the excessive aerodynamic additional torque on the cover plate of the wing storage tank of a certain missile during the expansion of the wings, the use of a single cover plate can produce too much resistance to the wing under the condition that the working angle is satisfied and can rebound smoothly, which affects the The wings unfolded smoothly, and the rigidity r...
