CASING SHELL OF AIRCRAFT Russian patent published in 2018 - IPC B64C1/12 F42B15/34 B64G1/58 

FIELD: aviation.

SUBSTANCE: for a shell with a long generatrix L and a smooth bearing wall of thickness δ of casing of cylindrical, conical or biconical form - in the wall of the shell from one or two ends axisymmetrically blind holes of diameter d and length l₁, l₂ are made in the way that δ=d+2(0.5-4.0) mm, L=(l₁+l₂)+(2-20) mm. A heat accumulating inserts or a balancing mass is installed in one or more cavities of a blind hole. The heat-accumulating insert is made of a material with a phase transition at the temperature not lower than +70°C. In open part of the blind hole, a groove with a diameter D and a depth h is made in a way that D=ƒ+(0.1-0.8) mm, h=S+(0.1-2.0) mm, where ƒ is diameter of the edge of heat-accumulating insert cork, S is thickness of the cork edge.

EFFECT: improvement of the criterion of efficiency - cost - time of creation and development.
