POWER SHELL FROM LAMINAR COMPOSITE MATERIAL Russian patent published in 2016 - IPC F17C1/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in designs of gas and hydraulic filters and accumulators and all similar vessels using shells from composite materials, as well as in aircraft and rocket engineering articles, for example, as fuel tanks and solid-propellant rocket engines housings. Power shell 1 comprises coupling end frame 2 with pins 4 arranged in radial slots 3 distributed along circumference. On pins 4 there cylindrical threaded shanks 6 are made, on which circular nuts 7 are arranged, which are in contact with interface ring laminar material along conic surfaces of recesses 8.

EFFECT: invention allows to increase joint unit strength and enlarge application of power shells from layered composite materials.
