Assembly method of flexible thermal insulation material used for cover heat seal

Abstract

The invention relates to an assembly method of flexible thermal insulation material used for cover heat seal and relates to the technical field of thermal protection assembly. The theory of the assembly method is that in an assembly process, a cover does not directly contact with the flexible thermal insulation material with rough surface, but contacts directly with a copper foil plate; a smooth surface is used to reduce the force of friction in a falling process of the cover; through extruding copper foil plates on the two sides of an opposite angle of the cover firstly, good flexibility of the copper foil plates is used to ensure the fact that in an extruding process, protected flexible materials do not produce deformation, delamination and falling off. In the process of extruding the opposite angle, the flexible thermal insulation material is made to be thinner; the assembly space of the other opposite angle is correspondingly increased; and the normal assembly of the cover and theflexible thermal insulation material is finally achieved; and the effect of cover heat seal is ensured. The assembly method of flexible thermal insulation material used for cover heat seal solves thedifficulty that in the last cover seal process in the final batten down of an aircraft, when the flexible thermal insulation material is extruded, breakage and deformation are prone to happen, so thatthe normal assembly cannot be conducted.

Description

technical field [0001] The invention relates to the technical field of thermal protection assembly, in particular to an assembly method of a flexible heat insulating material used for heat sealing of a flap. Background technique [0002] When the aircraft is flying at high speed in the atmosphere, on the one hand, the surface of the aircraft is faced with severe aerodynamic heating problems. In order to ensure that the equipment and fuel in the cabin work normally within a certain temperature range, the outer surface of the aircraft needs to be heat-proof design. The new integrated thermal protection structure for thermal insulation is composed of a three-layer structure, namely the upper and lower ceramic panels, and the middle aerogel layer (such as figure 1 The thermal protection structure has good thermal insulation, load bearing, deformation matching and other comprehensive properties, and can meet the thermal protection requirements of the aircraft during high-speed fl...

AI Technical Summary

Problems solved by technology

When the cover is not installed, the flexible heat insulation material is first placed on the side of the heat protection member around the cover and bonded with an adhesive. At this time, the flexible heat insulation material is in a free and uncompressed state, so the cover will fall. Scratching with the flexible heat insulation layer, one situation is that the flexible heat insulation material is delaminated or damaged, which affects the heat sealing effect of the cover; the other situation is that the flexible heat insulation material is squeezed to the lower part, causing the cover to fall behind It cannot be properly installed in place due to partial padding
