Technical Field
The invention belongs to the technical field of aviation manufacturing, and particularly relates to an installation technology of an embedded conformal radome.

The radome is a special component on the airplane, and the structural form and the shape of the radome are different according to the performance of equipment and different installation positions. The antenna housing is usually made of composite materials, and not only needs to meet the performance requirements of equipment and electrical appliances, but also needs to meet the aerodynamic requirements.
The prior mounting technology of the antenna housing is as follows: the radome is installed with the machine body in a complete finished product state, namely, the bonding surface and the edge of the radome are in a clean edge state, and connecting holes are completely manufactured; preparing a machine body connecting hole according to a connecting hole on an antenna housing, and assembling a connecting piece; and completing the installation of the antenna cover. The advantages are that: the antenna housing is complete in state, does not need secondary processing when being installed with the machine body, and is rapid in assembly and high in efficiency; the disadvantages are that: the antenna housing and the machine body are required to be high in manufacturing precision and good in coordination, and the assembly requirements of the binding surface and the connecting hole are met.
The method is suitable for the radome with the lapped body surface. For the embedded lap joint type antenna housing, the fitting degree of the antenna housing and the joint surface of the machine body is considered, the requirement of clearance fit with the periphery of the machine body structure and the requirement of shape (conformal) deviation are also considered, and the existing method cannot meet the installation requirement.

It is required to solve technical problems in the installation of an embedded conformal radome: the problem of the fitting of the radome and the assembly surface of the machine body is solved; secondly, the problem of the fit clearance between the radome and the circumference of the machine body is solved; the problem of shape deviation of the radome and the machine body is solved; fourthly, the problem of repeated positioning of the antenna housing and the machine body is solved.
The technical scheme of the invention is as follows: a method for installing an embedded conformal antenna cover is provided, which comprises the following steps:
firstly, fixing an inner-shaped supporting piece on a machine body, wherein the inner-shaped supporting piece is used for carrying out shape-preserving support on an antenna housing in the adjusting process; buckling the radome on the inner-shaped support member by hoisting, so that the periphery of the radome corresponds to a structural opening frame of an antenna area on the machine body;
repairing the periphery of the antenna housing and the structural opening frame to enable the matching gap between the antenna housing and the periphery of the structural opening frame, the bonding surface gap and the appearance step difference to meet the installation requirement;
Drilling a radome positioning hole on the radome, positioning and fastening the radome relative to the structural opening frame, and drilling a connecting hole for fixedly connecting the radome and the structural opening frame;
fourthly, the antenna housing is lifted away from the machine body, and a fastening piece is installed on the structural opening frame;
fifthly, after the structural opening frame is coated with the sealant, the antenna housing is installed on the structural opening frame;
step six, disassembling the antenna housing, and shaping the sealant;
and seventhly, removing the inner-shaped supporting piece, installing the antenna housing on the structural opening frame, and coating a waterproof coating.
Further, the radome is also fastened to the inner shape support by tightening the bandage in steps one to three.
The invention has the advantages of
According to the invention, by controlling the manufacturing technical states of the antenna housing and the machine body opening frame, selecting appropriate process equipment, planning a reasonable installation process flow, and utilizing a process compensation mode, the manufacturing precision requirements on the antenna housing and the machine body opening frame are reduced, and the installation of the embedded conformal antenna housing is ensured to meet the design pattern requirements.
