Abstract

The invention discloses a kind of connection structures of newer versions of these missiles antenna house, including connection ring and ceramic nose cone, a circle raised platforms are provided on ceramic head conical inner surface, a circle flange is provided at the top of connection ring, flange is stuck in the raised platforms of ceramic head conical inner surface, several equally distributed skewed slots are provided on connection ring outer wall, by being provided with a circle raised platforms on ceramic head conical inner surface, a circle flange is provided at the top of connection ring, flange is stuck in the raised platforms of ceramic head conical inner surface, by the way of mechanical connection, ensure being reliably connected between ceramic nose cone and connection ring, it solves the problems, such as to use bearing capacity existing for the ceramic nose cone of adhesive connection and connection ring poor at present;Several equally distributed skewed slots are offered in connection ring simultaneously, the rigidity of connection ring can be effectively reduced, and under the high temperature conditions, even if connection ring expands, ceramic nose cone will not be caused to rupture, practical value with higher.

Description

A kind of connection structure of newer versions of these missiles antenna house
Technical field
The present invention relates to missile-borne radome technical field, in particular to a kind of connection structure of newer versions of these missiles antenna house.
Background technique
It is reliably connected between missile-borne radome and body and the requirement of the various load such as transmission force, heat to meet, guided missile day Irdome root is typically provided with connection ring, when missile-borne radome material selection ceramic material, since ceramics are that fragile material is unsuitable Punching or fluting, are generally attached using bonding mode between connection ring and missile-borne radome cover, connection ring and cover it Between use bonding mode, stress can be evenly distributed on by adhesive in carrying by a degree of deformation entire is glued area Domain drops stress concentration to expand loaded area to greatest extent.
But the weakness of bonding mode is also very prominent, and the connection of bearing capacity relative mechanical is weaker when high temperature, and with temperature Degree is lasting to be increased, and the bearing capacity decline of adhesive faster, will lead to ceramic nose cone and fall off from connection ring, meanwhile, it is traditional Connection ring can be expanded in hot conditions, and the ceramic nose cone outside connection ring is caused to rupture.
Summary of the invention
Present invention solves the technical problem that: a kind of connection structure of newer versions of these missiles antenna house is provided, current radar is solved Following problems existing for antenna house:
(1) the problem of adhesive bearing capacity is poor, and ceramic nose cone is easy to cause to fall off from connection ring.
(2) traditional connection ring can be expanded in hot conditions, cause what the ceramic nose cone outside connection ring ruptured to ask Topic.
Technical solution of the present invention:
A kind of connection structure of newer versions of these missiles antenna house, including connection ring and ceramic nose cone, the ceramic head conical inner surface On be provided with a circle raised platforms, be provided with a circle flange at the top of the connection ring, the flange is stuck in ceramic nose cone In the raised platforms of wall, several equally distributed skewed slots are provided on the connection ring outer wall.
The angle of the skewed slot and horizontal plane is 45 °~60 °.
The ceramic head conical inner surface and connection ring contact site is coated with one layer of sealant.
The connection ring root is provided with guided missile interface.
Beneficial effects of the present invention: a kind of connection structure of newer versions of these missiles antenna house is provided, by ceramic head conical inner surface On be provided with a circle raised platforms, a circle flange is provided at the top of connection ring, flange is stuck in the protrusion of ceramic head conical inner surface On platform, by the way of mechanical connection, it is ensured that being reliably connected between ceramic nose cone and connection ring solves current use Adhesive connects the problem of bearing capacity difference existing for ceramic nose cone and connection ring;It is offered in connection ring simultaneously several uniform The rigidity of connection ring can be effectively reduced in the skewed slot of distribution, under the high temperature conditions, even if connection ring expands, will not cause Ceramic nose cone rupture, practical value with higher.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is connection ring structure schematic diagram in the present invention;
It is identified in figure: 1, connection ring, 2, raised platforms, 3, skewed slot, 4, guided missile interface, 5, flange, 6, ceramic nose cone.
Specific embodiment
The present invention is described further with reference to the accompanying drawing, a kind of connection structure of newer versions of these missiles antenna house, including Connection ring 1 and ceramic nose cone 6 are provided with a circle raised platforms 2,1 top of connection ring on 6 inner wall of ceramic nose cone It is provided with a circle flange 5, the flange 5 is stuck in the raised platforms 2 of ceramic 6 inner wall of nose cone, on 1 outer wall of connection ring It is provided with several equally distributed skewed slots 3.
The angle of the skewed slot 3 and horizontal plane is 45 °~60 °, can ensure that the Stiffness of connection ring 1 arrives and ceramic head 6 matching of cone.
6 inner wall of ceramic nose cone and 1 contact site of connection ring is coated with one layer of sealant, it is ensured that is close inside guided missile cover Seal ring border.
1 root of connection ring is provided with guided missile interface 4, connect with missile airframe.
