Fusion structure of missile wing connection lug channel and missile body

Abstract

The invention discloses a fusion structure of a missile wing connection lug channel and a missile body. The fusion structure is formed by direct numerical control integration processing of the missile body and the lug channel. The missile wing connection lug channel and the missile body are integrally designed and fused, an appropriate aluminum sectional material is selected, the missile body and lug channel are directly finished by numerical control processing, an assembly link is not required, a connection tool is omitted, working efficiency is improved, and parallel operation is facilitated.

Description

Technical field [0001] The invention relates to a fusion structure of a projectile wing connecting ear groove and a projectile body, belonging to the field of projectile body structure design. Background technique [0002] During the flight of the missile, the missile body not only has to bear the local aerodynamic force acting on its surface, the mass force of the structure itself, and the mass forces of the various parts of the missile body, but also bear the greater concentration of the missile wings, tail and other parts through the fixed joints. Load. The local aerodynamic force on most surfaces of the projectile body is relatively small, and is approximately symmetrically distributed along the circumference of the projectile body cross-section, which can basically balance itself without being transmitted to other parts of the projectile body. The components are basically symmetrical according to the plane of symmetry of the projectile body. Distribution, its mass force can...

AI Technical Summary

Problems solved by technology

Most of the lightweight aluminum materials used for the missile body have poor welding performance and are easily deformed after welding

The lugs are riveted or screwed to the bomb body, and the load on the bomb is transmitted to the wing-body joint through rivets or screws. Due to inconsistent fixing tightness and uneven force, it is easy to cause excessive force on some fasteners to wear and deform even broken

The lug grooves are assembled on the bomb body, no matter what kind of process is used, even if there is a frame tooling, it is difficult to guarantee the relative position accuracy requirements of the lug grooves and the body, that is, the wings and the body
