Problems solved by technology

For high-temperature environments, the traditional solution is to add a heat-resistant layer on the surface, but the thicker the heat-resistant layer, the worse the wave transmission performance. The traditional antenna shell structure is no longer suitable for high-speed aircraft.

Description

technical field [0001] The invention relates to an aircraft airborne antenna structure, which belongs to the technical field of aircraft structure design. Background technique [0002] As the speed of the aircraft increases, the aerodynamic heating of the outer surface of the aircraft becomes more and more significant, and a heat-resistant layer needs to be added to prevent heat from entering the aircraft. However, in order to ensure the wave-transmitting performance of the antenna on the outer surface of the aircraft, a heat-resistant layer cannot be added to the surface. Therefore, the design of the antenna shell needs to use high-temperature resistant materials, and the high temperature of the antenna cannot be conducted to the interior of the aircraft. The traditional antenna shell structure is no longer suitable for high-speed aircraft. It is necessary to design a new type of airborne antenna structure scheme to meet the urgent needs in the field of airborne antennas....
