Wing surface root rib and capsule section longitudinal beam integrated structure of guided missile

Abstract

The invention relates to a wing surface root rib and capsule section longitudinal beam integrated structure of a guided missile. A wing surface root rib is a connecting member of a wing surface framework and a capsule section longitudinal beam of the guided missile; a lapping side of the wing surface root rib is integrated with the longitudinal beam on the capsule section of the guided missile; an outer surface on the lapping side of the wing surface root rib is consistent with an outer surface of the capsule section of the guided missile; an outer end surface of the wing surface root rib is abutted and matched with a connecting surface of the wing surface framework; the wing surface root rib is fixedly connected with a guided missile capsule section framework I and a guided missile capsule section framework II by using rivets; a rear band plate is arranged on the rear edge of the wing surface root rib and is fixedly connected with a guided missile capsule section framework III by using rivets; the wing surface root rib is connected with the guided missile capsule section framework I and the guided missile capsule section framework II; and after the rear band plate is fixedly connected with the guided missile capsule section framework III, a guided missile cover is rived with a guided missile capsule body framework. According to the wing surface root rib and capsule section longitudinal beam integrated structure disclosed by the invention, the design of a capsule section reinforcing frame and a longitudinal beam is reduced, the structural weight is reduced and favorable pneumatic appearance is obtained simultaneously; and the wing surface root rib and capsule section longitudinal beam integrated structure is suitable for the riveted capsule section and is free from being detached after being assembled without influencing storage and transportation and is suitable for guided missiles and small-sized airplanes.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an integrated structure of a root rib of a missile wing surface and a longitudinal beam of a cabin section. Background technique [0002] At present, in the structural design of missiles, the airfoil and the missile body are manufactured separately, and they are connected by detachable joints; generally, lug-type joints and multi-tenon joints are used, and the force transmission of the joint parts is concentrated. A very strong reinforcing frame is arranged at the connecting part of the main joint, and the structural weight is relatively large. Contents of the invention [0003] The object of the present invention is to provide an integrated structure of root rib of missile wing surface and cabin longitudinal beam which is not disassembled after assembly and does not affect storage and transportation, which is suitable for missiles and small aircraft. [0004] The technical scheme ...
