Segmented airborne radome

Abstract

The invention relates to a segmented airborne radome which comprises a front cowling, an antenna working cover, a back cowling, a front separating frame and a back separating frame. The front separating frame and the back separating frame supply rigid supporting to the front cowling, the antenna working cover and the back cowling. The segmented airborne radome satisfies mechanical performance requirements such as rigidity and load of an airborne radome. The flange of the front cowling and the flange of the back cowling realize direct combination with an airplane body structure, thereby realizing simple structure and preventing structure weight increase caused by combination of other structures with the airplane body. The back cowling has a mode that a streamline type composite material rectifying sheath is combined with a metal-reinforced section bar. Not only is a good pneumatic shape ensured, but also enough strength and rigidity of the back cowling are ensured. The front separatingframe and the back separating frame utilize a mode that the metal section bar is combined with a composite material web plate, thereby realizing sufficient bearing capability and effectively reducingstructure weight.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and in particular relates to a segmented airborne radome. Background technique [0002] A radome is a structure that protects an airborne 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. The purpose of using the radome is as follows: [0003] 1) Protect the antenna system from harsh external environments such as wind, rain, snow, sand and solar radiation, so that the performance of the antenna system is stable and reliable, and at the same time reduce the wear, corrosion and aging of the antenna system and prolong its service life. [0004] 2) Eliminate wind load and wind moment, reduce the driving power of the rotating antenna, reduce the weight of the mechanical structure, reduce the inertia, and in...
