Problems solved by technology

[0002] When the aircraft flies at high speed, the air forms a boundary layer on its surface. This part of the air has a relatively high temperature, and it is very easy to flow into the airframe through the gaps in the airframe structure, causing the airframe to rise sharply and make some key components inside the airframe invalid. , or even damage, causing safety accidents

Abstract

The invention belongs to the technical field of thermal protection design, and particularly relates to a cabin door thermal sealing structure which comprises a cabin door opening frame; an annular heat sealing plate which is connected with the cabin door opening frame and surrounds the cabin door opening frame; an annular heat sealing strip which is connected with the cabin door opening frame and / or the annular heat sealing plate; and a cabin door which is installed on the cabin door opening frame, and when the cabin door is closed, the cabin door opening frame is blocked, and the annular heatsealing strip is extruded in the direction of the annular heat sealing plate; the annular heat sealing strip forms heat sealing between the annular heat sealing plate and the cabin door; and when thecabin door is opened, the cabin door opening frame is unblocked.

Description

technical field [0001] The application belongs to the technical field of heat protection design, and in particular relates to a heat sealing structure for a hatch. Background technique [0002] When the aircraft flies at high speed, the air forms a boundary layer on its surface. This part of the air has a relatively high temperature, and it is very easy to flow into the airframe through the gaps in the airframe structure, causing the airframe to rise sharply and make some key components inside the airframe invalid. , or even damage, causing safety accidents. [0003] The gaps in the body structure are mainly the gaps between the hatch door and the hatch door frame. The current gap between the hatch door and the hatch door frame cannot be effectively sealed to prevent the high-temperature air from the boundary layer on the body surface from flowing into the body. Inside. [0004] In view of the existence of above-mentioned technical defect, propose this application. [000...
