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.
