Thermal deformation coordinated missile dome attachment ring

Abstract

The invention discloses a missile dome connecting ring having thermal deformation compatibility. The missile dome connecting ring having thermal deformation compatibility comprises a connecting ring lining, a connecting ring flange and the like. The connecting ring lining is fixedly connected with the connecting ring flange. The front end face of the connecting ring lining is located on the connecting ring lining. Hole-shaped stress grooves are located on the front end face of the connecting ring lining. Linear stress grooves are located on the connecting ring lining. The back end face of the connecting ring flange and the front end face of the connecting ring flange are located on the front side and the back side of the connecting ring flange correspondingly. Connecting ring threaded holes are located in the back end face of the connecting ring flange. A heat-proof coating is located on the outer surface of the connecting ring flange. The missile dome connecting ring having thermal deformation compatibility can guarantee that when a missile flies at a high mach number, a missile dome is complete in structure, solves the problem that the missile dome is damaged because of overheating and has the advantages of being simple in technology, safe and reliable.

Description

technical field [0001] The invention relates to a connection ring, in particular to a missile head cover connection ring with coordinated thermal deformation. Background technique [0002] The connecting ring device is an important part of the hood design in the field of missile body structure design. The ceramic hood and the cabin are connected through the connecting ring. The missile flies at a high Mach number, and the aerodynamic heating deformation of the ceramic dome is relatively large. The connecting ring needs to have a thermal deformation capability coordinated with it, so as to reduce the thermal stress at the bonding position of the ceramic dome and the connecting ring, so that the ceramic dome will not Thermal stress damage occurs to ensure the safety and reliability of the missile in flight. [0003] At present, a variety of structural methods have been developed in the design of the connecting ring of the missile ceramic hood at home and abroad, such as: (1) ...
