Vehicle-mounted knife-type antenna cover and precise manufacturing method thereof

Abstract

The invention discloses a vehicle-mounted knife-type antenna cover and a precise manufacturing method thereof. The antenna cover is formed by combining an inner surface layer, a functional layer, a bottom plane layer, a stop opening layer and an outer surface layer. The inner surface layer, the bottom plane layer, the stop opening layer and the outer surface layer are made of different specifications of high-intensity glass fiber prepregs. The functional layer is made of different materials of high-intensity glass fiber prepreg, a metal array and a nomex honey comb, thereby satisfying different functions of wide frequency, high wave transparency and invisibility. The inner surface layer, the stop opening layer, the functional layer, the bottom plane layer and the outer surface layer are successively laid on a core die sequentially, an outer die is assembled and a vacuum bag is used for sealing, and through a vacuum system and an oven, heating and solidification are achieved to form a whole body. A layering method and laying sequence are set, so high speed discharging and precise prefabrication of different layers can be achieved. By combining a metal outer die and a silicone rubber core die, the size precision of the antenna cover is ensured and the technique cost is reduced.

Description

technical field

[0001] The invention relates to a radome and a manufacturing method thereof, in particular to an airborne knife-shaped radome with the characteristics of high strength, wide frequency, high wave penetration and stealth function and its precise manufacturing method. Background technique

[0002] The blade antenna has the advantages of wide frequency band and small size, and is widely used as a communication antenna in aircraft communication systems. On the other hand, after the airborne antenna is installed on the aircraft platform, it will affect the distribution of the center of gravity, aerodynamic performance and stealth performance of the aircraft. When the antenna is installed on the airframe, as the load of the aircraft, the local weight of the aircraft will be increased, which will change the distribution of the center of gravity of the original aircraft, which will affect the balance, safety and maneuverability of the aircraft. Therefore, it should be...
