Problems solved by technology

[0003] 1) Made of natural rubber, it has poor wear resistance, is easy to be worn, and has poor cold resistance. It is prone to hardening failure when exposed to low temperature environment
[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 sealing structure which comprises a fuselage opening frame; a canopy which is connected to the fuselage opening frame, wherein a mounting groove is formed in the edge of the canopy; clamping blocks are arranged on the side walls of the mounting groove, and a canopy penetrating hole is formed in the bottom wall; a silicone rubber hose which is provided with an inflation hole and laid in the mounting groove, wherein the outer wall of the silicone rubber hose is provided with a clamping groove; the clamping block is clamped in the clamping groove; an inflation nozzle which is connected into the inflation hole, penetrates through the canopy through hole and is connected into the cabin ventilation pipeline so that the silicone rubber hose can be inflated and deflated, and the silicone rubber hose has an inflation state, wherein after the canopy is closed, the silicone rubber hose expands and fills the space between the canopy and the fuselage opening frame; and a deflation state, wherein the silicone rubber hose shrinks, and a gap is formed between the canopy and the fuselage opening frame after the canopy is closed. In addition, the invention relates to an assembling method of the aircraft canopy fuselage opening frame 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 sealing structure and an assembly method. 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 hardening 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 scr...
