Problems solved by technology

[0003] In the prior art, the installation accuracy of the radar equipment cabin and the radome is relatively low. Since the radar equipment cabin and the radome need to be connected at multiple points, there is a connection error between each connection point, and the connection errors accumulated at each connection point Usually reduces its tightness

Abstract

The invention discloses an early warning radar and an aircraft provided with the same. The early warning radar comprises a radar device cabin and a radar antenna cover, wherein the radar device cabin has a skeleton; the radar antenna cover is in sealed connection with the skeleton so as to seal the radar device cabin; when the radar antenna cover is connected with the skeleton, a deformation compensation position is arranged between the radar antenna cover and the skeleton; the deformation compensation position is used for being deformed when the radar antenna cover and the skeleton are connected so as to compensate tolerance accumulation when the radar antenna cover and the skeleton are in sealed connection; and a rubber plate fills the deformation compensation position for sealing. By adopting the structure, tolerance accumulation is totally arranged at the deformation compensation position, and compared with the prior art, tolerance accumulation can be prevented, and tolerance can be integrated and then the tolerance can be solved through deformation.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an early warning radar and an aircraft with the same. Background technique [0002] The radome generally consists of a radar equipment compartment of an all-metal structure and a radome of a composite material. The size of the radome is large and the shape is generally a mushroom cloud. The connection between the radar equipment cabin and the radome is one of the difficulties in the development. The quality of the connection determines the direct force transmission, convenient assembly, good waterproof performance, and light weight. The structure is difficult to design and there are too many counterweights. How to effectively control the deformation and make the design controllable requires a good structural form so that the load transmission and installation accuracy can be guaranteed, and the structural weight occupied is relatively light. [0003] In the prior art, the insta...
