Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] combine figure 1 , a small-diameter projectile wing expansion mechanism with self-locking and position-limiting functions, which assists the small-diameter projectile wing to expand, and realizes limit self-locking after being deployed in place, which can effectively resist wind loads, including mounting base 4 and N sub-mechanisms, N= 3, 4, N sub-mechanisms and fins 1 are evenly arranged on the outer wall of the mounting seat 4, and each fin 1 rotates and unfolds around a sub-mechanism.

[0020] The wing 1 adopts an arc-shaped wing structure design, and three protrusions are arranged at intervals in sequence at the root of the wing. The inner side of the protrusion located in the middle is provided with a card slot 10, and the outer side of the three protrusions is provided with an expansion limit. Surface 11.

[0021] The mounting seat 4 is a cylin...

Abstract

The invention discloses a small-diameter missile fin unfolding mechanism with limiting and self-locking functions. The mechanism comprises a mounting seat and N sub-mechanisms, and is characterized inthat the mounting seat is used for connecting fins with a missile body, the N sub-mechanisms and the fins are evenly arranged on the outer wall of the mounting seat, and each fin rotates around the corresponding sub-mechanism to be unfolded. According to the mechanism, limited structural space is fully utilized, unfolding, limiting, locking and unlocking functions of the fins are achieved, the structure is simple, the cost is low, and the mechanism is reliable.

Description

technical field [0001] The invention belongs to the field of folding wings, and in particular relates to a small-diameter elastic wing expansion mechanism with a self-locking and position-limiting function. Background technique [0002] Folding wings are mainly used in missiles, rockets and other fields, which can reduce the radial size of the missile body, increase the ammunition capacity of the weapon system, and facilitate storage, transportation and launch in the launch box or launch tube. When the projectile is in the launch tube or on the launch frame, part or all of the wings are constrained to form a folded state. When the projectile flies away from the launch tube or launch frame, the projectile wings are released from the constraints and rely on elastic torsion elements (torsion bar or torsion spring, etc.) to quickly expand to a predetermined position, and it is required to keep the wings from rebounding under the action of air resistance and other loads, so as to...
