Problems solved by technology

[0003] 1) Made of natural rubber, it has poor wear resistance, is easy to be worn out, and has poor cold resistance, and is prone to failure when exposed to low temperature environments
[0004] 2) In order to ensure the tightness between the canopy and the fuselage opening frame, the sealing structure is squeezed between the canopy and the fuselage opening frame. When the aircraft canopy is opened and closed, it is easy to scratch the sealing structure, causing the sealing structure to destroy;
[0005] 3) The sealing structure is connected to the canopy, the connection is not reliable enough, and it is easy to fall off, which leads to dangerous accidents

Abstract

The invention belongs to the technical field of aircraft canopy fuselage opening frame sealing design, and particularly relates to an aircraft canopy fuselage opening frame inflation sealing structure. The structure comprises a fuselage opening frame, a canopy, natural-color fine plain cloth, a silica gel hose and an inflation nozzle; the canopy is connected to the fuselage opening frame, and a mounting groove is formed in the edge of the canopy; the bottom wall is provided with an opening; the natural-color fine plain cloth is bonded in the mounting groove and is provided with an opening; the silica gel hose is laid in the mounting groove and is bonded to the natural-color fine plain cloth, and an inflation hole is formed in the silica gel hose; the inflation nozzle is connected into the inflation hole, penetrates through the bottom wall of the mounting groove and the opening in the natural-color fine plain cloth and is connected into a cabin ventilation pipeline, so that the silica gel hose can be inflated and deflated and has an inflation state and a deflation state, in the inflation state, the silica gel hose is inflated and expanded, after the canopy is closed, the space between the canopy and the fuselage opening frame is filled with the silica gel hose, in the deflation state, the silica gel hose is deflated and contracted, and after the canopy is closed, a gap exists between the canopy and the fuselage opening frame. In addition, the invention relates to a method for achieving assembling of the aircraft canopy fuselage opening frame inflation sealing structure.

Description

technical field [0001] The application belongs to the technical field of sealing design of an aircraft canopy cover fuselage opening frame, and in particular relates to an aircraft canopy cover fuselage opening frame inflatable sealing structure and an assembly method thereof. Background technique [0002] A sealing structure is designed between the frames of the fuselage of the canopy to prevent gas leakage at this part when the aircraft is flying. Currently, the sealing structure between the frames of the canopy and the fuselage has the following defects: [0003] 1) Made of natural rubber, it has poor wear resistance, is easy to be worn out, and has poor cold resistance, and is prone to failure when exposed to low temperature environments. [0004] 2) In order to ensure the tightness between the canopy and the fuselage opening frame, the sealing structure is squeezed between the canopy and the fuselage opening frame. When the aircraft canopy is opened and closed, it is ea...
