Abstract

The invention relates to the field of aerospace missiles, in particular to an aviation missile body which comprises a missile body. The end is provided with a connecting end used for being connected with the projectile body, a first connecting hole is formed in the connecting end in a penetrating mode, and the first connecting hole is of a through hole structure with the inner wall being a smooth face; the connecting assembly is arranged between the end head and the projectile body and comprises a first connecting part and a connecting rod, the connecting rod penetrates through the first connecting hole and then is fixedly connected with the projectile body, and the first connecting part can be connected with the connecting rod on the other side of the connecting end and abuts against the connecting end. And it is guaranteed that the end and the projectile body have the stable connection relation, so that the scheme can be used in the end connection process of the large-size and large-mass tungsten infiltrated copper material, and the related blank in the field is filled up.

Description

technical field [0001] This application relates to the field of aviation missiles, in particular to an aviation missile body. Background technique [0002] Tungsten infiltrated copper material is a special immiscible composite material obtained by infiltrating metal copper with high melting point and high strength sintered tungsten skeleton. The material combines the advantages of both tungsten and copper, and has good high temperature resistance and burning resistance. Corrosion and high strength, high hardness and other properties, mainly used in the high temperature field of aerospace. It is often used as the nose cone of missiles in aerospace. [0003] However, copper infiltrated tungsten is a highly brittle material. For large-size and high-quality tungsten-infiltrated copper terminals, it is not possible to directly process threaded holes on the surface and connect them to the body with screws, which will easily cause stress to concentrate on the threaded holes, caus...
