| description | The invention provides an air inlet pipe of a multi-navigation-state aircraft air. The air inlet pipe comprises a pipe body, a sealing cover arranged at the end of the pipe body and a driving piece for driving the sealing cover in the axial direction of the pipe body, wherein the sealing cover is provided with an inserting section matched with the inner wall of the pipe body, the inserting sectionand the inner wall of the pipe body are provided with a radial sealing structure, the radial sealing structure at least comprises a first sealing ring and a second sealing ring which are provided with openings, and the openings of the first sealing ring and the second sealing ring are arranged back to back in the axial direction of the pipe body, so that the parts, protruding out of the radial direction of the sealing cover, of the openings form a scraping structure on the inner wall of the pipe body. The radial seal has the self-cleaning capacity, the outer hydraulic pressure is used for automatically achieving seal |
