Repair assembly for screw head special for radar stealthy combat aircraft

Abstract

A repair assembly for a screw head special for a radar stealthy combat aircraft comprises a wave-absorbing ring piece and a wave-absorbing groove core which are in clearance fit. The wave-absorbing groove core is arranged in the wave-absorbing ring piece in a penetrating-sleeved mode. The wave-absorbing ring piece is a circular-ring-shaped body. The upper end face of the wave-absorbing ring piece is a smooth plane. The lower end face of the wave-absorbing ring piece is a rough plane. The wave-absorbing groove core is a step column and comprises a groove core cap, an upper groove core body, a lower groove core body, a ventilation channel and a groove core rod. The center lines of the groove core cap, the upper groove core body, the lower groove core body and the groove core rod coincide on one straight line, and the groove core cap, the upper groove core body, the lower groove core body and the groove core rod are in series connection sequentially to form a whole. According to the repair assembly, the radar stealthy effect is prominent, reliability is high, operation is simple, installation is convenient, and the maintenance efficiency of the radar stealthy combat aircraft during combat is high.

Description

technical field [0001] The invention relates to a repair assembly for screw heads of radar stealth combat aircraft, which is suitable for surface treatment of exposed nail heads on special screws for radar stealth combat aircraft, and belongs to the technical field of stealth combat aircraft. Background technique [0002] The use of stealth technology on today's combat aircraft has become a mainstream trend, and this technology has become the standard configuration of combat aircraft. In the field of stealth, the main ways to realize its stealth: the use of shape stealth technology, radar absorbing materials and wave-transmitting materials, electronic measures to reduce the radar cross section of weapons, plasma stealth technology and control of three strong scattering sources (radar antenna cabin scattering, Inlet cavity and engine compressor scattering, cockpit scattering), etc. The above technologies cannot completely solve the stealth problem, because for the extremely ...

AI Technical Summary

Problems solved by technology

Just to say that there are tens of thousands of exposed nail heads of various models, if not repaired, the stealth problem of related weak scattering sources will be exposed, which is enough to make it impossible to achieve the stealth target of an extremely low RCS stealth aircraft

However, at present, there are two major problems in the repair parts of the special screws and nail heads of the relevant radar stealth combat aircraft: 1. When the radar stealth combat aircraft is operating at high altitude, the repair parts cannot withstand the extreme environment and will fall off from the nail head

2. When the combat aircraft is maintained, the groove core cannot be conveniently or even disassembled, making it inefficient
