Abstract

The invention discloses an active and passive radar seeker radome and an aircraft and relates to the field of an aircraft radome. The radome comprises a radome body, a shell, a heat insulation shieldand a heat insulation layer, wherein the shell is fixed at an interior of the radome body; the shell comprises a front frame and a rear frame which are disposed at intervals; a cabin section for fixing a passive antenna is disposed between the front frame and the rear frame; the heat insulation shield is disposed in the radome body and fixed on the front frame; and the heat insulation layer is attached between an inner side of the radome body and an outer side of the shell. According to the active and passive radar seeker radome provided by the invention, heat shielding, wave transmission, conformal installation of an antenna array and the radome, and vibration-damping installation of an active seeker can be implemented.

Description

technical field [0001] The invention relates to the field of aircraft radome, in particular to an active and passive radar seeker radome and an aircraft. Background technique [0002] Aircraft often fly at high speed in harsh thermal and mechanical environments. In order to ensure the normal operation of the seeker and maintain the aerodynamic shape, it is necessary to design a radome outside the seeker. The radome needs to meet the functions of wave transmission, load bearing and heat protection at the same time. The structural design of the radome is the focus and difficulty of the aircraft structural design. [0003] According to different use environments, choose different materials to design the radome cover body. Generally speaking, resin-based composite materials can be selected for environments with low thermal environment, such as glass fiber reinforced plastics, polytetrafluoroethylene-based composite materials, etc.; for harsh thermal environments It is necessary...
