Embodiment Construction

[0020] refer to Figure 1-Figure 6 . In the preferred embodiment described below, an airborne lightning protection radome includes: a radome shell 2 with the cover wall made into a curved shape, and a metal lap 1 fixedly connected to the inner edge of the radome shell 2 , wherein the material of the metal strap 1 is aluminum alloy. The radome shell 2 is a multi-layer composite material structure formed by integral thermocompression molding of the metal pattern layer 5 and the non-metallic fiber layer 6 . The radome shell 2 is divided into an intermediate wave-transmitting area 3 surrounding the peripheral external installation area 4 according to functions. The intermediate wave-transmitting area 3 is a multi-layer composite material sandwich structure, and one or more layers of metal pattern layers 5 are arranged in the sandwich structure. , the rest are non-metallic fiber layers 6, and the metal pattern layer 5 is a frequency selection pattern 7 of array characteristics in...

Abstract

The invention relates to an onboard anti-thunder antenna cover, and aims to an anti-thunder antenna cover which is high in wave transmittance, high in strength and good in appearance consistency, is light and can be used for shunting a lightning induction load. The onboard anti-thunder antenna cover is implemented according to the following technical scheme that a cover wall is fabricated to be astream-lined antenna cover shell and is fixedly connected to a metal overlapped piece on an edge of an inner side of the antenna cover shell, the antenna cover shell is divided into an intermediate wave transmitting region encircling a surrounding external installation region, the intermediate wave transmitting region is of a multi-layer composite material dielectric sandwiched structure, a layeror more layers of metal patterns are arranged in the sandwiched structure, the remaining is a non-metal fiber layer, the metal pattern layers are frequency selection patterns having array characteristic at the wave transmitting region, the metal pattern layers are continuous metal patterns at the external installation region, metal powder is permeated into each laying layer of the surrounding external installation region so that the surrounding external installation region is converted to a conductive material, and the metal overlapped piece is pasted with an inner surface of the surrounding external installation region of the antenna cover shell 2 by conductive glue so as to achieve electrical conduction.

Description

technical field [0001] The invention relates to a lightning protection radome, in particular to an airborne lightning protection radome. Background technique [0002] A radome is a structural member that protects an antenna system from the external environment. It has good electromagnetic wave penetration characteristics in terms of electrical properties, and can withstand the effects of harsh external environments in terms of mechanical properties, such as storms, ice and snow, sand and dust, and solar radiation. Radomes are generally made of non-metallic materials, and most radomes are It consists of a hollow single-layer or multi-layer dielectric shell. The radome mainly has five structures: aviation radome, ground radome, inflatable radome, shell structure radome and space frame radome. From the use, it is divided into two categories: aviation type and ground (including shipborne) type. [0003] During the flight of the aircraft, the airborne radome has a high probabi...
