Embodiment 1

[0038] The outer cover 1 of the wave-transmitting cover is a cone, and the inner cover 2 is a combined structure of a hemisphere + a cylinder. The inner cover 2 is a structure of equal wall thickness, the wall thickness is 6mm, and the radius of the sphere and the cylinder is 170mm. The wall of the outer cover 1 The thickness varies between 15-20mm, the radius of the annular connecting ring 3 is 180-190mm, the position of the annular connecting ring 3 corresponds to the position of the cone on the inner surface of the outer cover 1, and the half-cone angle of the cone is 8°. The distance between the opening end surface of the outer cover 1 and the opening end surface of the inner cover 2 is 5 mm, and the opening end surface of the inner cover 2 is closer to the small end of the cover body.

[0039] The outer cover 1 is made of quartz fiber reinforced silica composite material, the inner cover 2 is made of polyimide composite material, and the connecting ring 3 is made of low expa...

Abstract

The invention relates to a wave-transmitting cover for a high-speed aircraft with functional partitions, including an outer cover, an inner cover and connecting pieces, wherein both the outer cover and the inner cover are semi-closed structures with one end open, the inner cover is located inside the outer cover, and the inner cover and the outer cover The space is connected and fixed by a connector, the connector is a ring connector, the inner surface of the ring connector is connected with the outer surface of the inner cover, the outer surface of the ring connector is connected with the inner surface of the outer cover, and the inner cover accommodates aircraft navigation electronic components ; The present invention adopts the double-layer structure wave-transmitting cover for the first time, and divides the inside of the wave-transmitting cover into two independent spatial regions from space, and forms a gradient anti-heat insulation function from three physical processes of heat conduction, heat radiation, and heat convection. While maintaining good structural strength and wave transmittance, the wave-transparent cover has excellent heat insulation performance.

Description

technical field [0001] The invention relates to a wave-transmitting cover, in particular to a function-partitioned combined wave-transmitting cover for a high-speed aircraft. This type of wave-transmitting cover is mainly used in the design of a high-speed aircraft. Background technique [0002] With the rapid progress of global aerospace technology, aircraft is developing towards high-speed and fast maneuvering. This type of aircraft has a prominent common feature, and they all need to be able to perform orbit-changing maneuvers in the atmosphere at an ultra-high Mach number for a long time, which greatly improves the performance of the aircraft. [0003] The new high-speed aircraft needs to have the function of terminal guidance. The radar shield installed on the head of the aircraft is a key functional component for guidance. (Radar guidance) comprehensive use function to ensure the normal use environment conditions of internal components. The single-layer radome equipp...
