Abstract

The invention belongs to the technical field of functional materials, and particularly relates to a hub cover with radar and infrared stealth functions. The hub cover comprises a disc flat plate, a flow guide groove, a flow guide lug, an annular corner piece and a metal foil. The flow guide groove is formed in one surface of the disc flat plate; the flow guide lug is arranged above the flow guide groove; the metal foil covers the other surface of the disc flat plate; a thermal reflection coating is sprayed on the metal foil; and the annular corner piece is connected with the disc flat plate in a riveting manner. According to the hub cover, infrared detection cooling is larger than or equal to 70%, and meanwhile the good radar stealth performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a hub cover with radar and infrared stealth functions. Background technique [0002] In the military field, radar is still one of the important technologies for searching targets in modern warfare. The development of absorbing materials that can efficiently absorb radar waves is an effective way to improve the survival of weapon systems. Therefore, absorbing materials are widely used in the military field. The absorbing material mainly consumes the radar wave in the form of heat energy inside the material through the dielectric loss of the material, or makes the radar wave interfere and cancel due to multiple reflections, so as to absorb and attenuate the radar wave projected into the object. Absorbing materials with better performance should have excellent impedance matching characteristics and attenuation characteristics. Impedance matching characteris...
