Rain erosion-prevention structure with wave transmission and quick disassembly functions

Abstract

The invention discloses a rain erosion-prevention structure with wave transmission and quick disassembly functions, which comprises a rain erosion head, a cushion block and a self-locking nut, and ischaracterized in that the outer surface of the front end of the rain erosion head is consistent with the outer profile of a radome, the rear end of the rain erosion head is a cylindrical section, theouter surface of the cylindrical section is provided with threads, and the cushion block is a conical section with a through hole, the conical section is sleeved with a cushion block, the outer conical surface of the cushion block is matched with the inner molded surface of the radome, the self-locking nut is arranged on the cylindrical section and located on the rear portion of the cushion block,and the cushion block is locked, so that the outer conical surface of the cushion block is tightly attached to the inner molded surface of the radome. The rain erosion-prevention structure solves theproblem that a traditional rain-corrosion cap has a greater impact on electrical properties and is not conducive to disassembly, the rain erosion-prevention is characterized in that a threaded connection structure of the rainproof head and the self-locking nut is made of polytetrafluoroethylene with a good wave-transmitting function, so that the rainproof structure has certain electromagnetic wave transmitting performance and is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of radar radome design, in particular to a rain-erosion-proof structure with the functions of wave penetration and quick disassembly. Background technique [0002] With the improvement of the technical level of the aircraft, the radar on the nose of the aircraft puts forward higher and higher requirements on the electrical performance, and the tip of the radome is severely affected by rain erosion. Corrosion cap, the traditional metal rain erosion cap has a great influence on the electrical performance, and the non-metal rain erosion cap is bonded to the radome composite material cover through cementation, which is not conducive to disassembly and maintenance. Contents of the invention [0003] Purpose of the present invention: [0004] Aiming at the problem that the traditional rain erosion cap has a great influence on the electrical properties and is not conducive to disassembly, the present invention i...
