Abstract: The technical result of the invention is that the proposed cylinder construction provides high performance at any given level of cyclic high-pressure and torsional loading with minimum weight and manufacturing cost.

Abstract: The technical result of the proposed invention is the absorption of the impact energy. The technical result is achieved by using metal composite pressure cylinder that contains a closed thin metal sealing liner, a pressure overwrap made of composite material formed by a combination of groups of layers of reinforcing material made of high-modulus filaments orientated in spiral and circumferential directions, and a protective overwrap fabricated from a composite material made of a group of layers of reinforcing material made of low-modulus filaments. Herewith, an energy damping shock absorber is installed on the part of the surface of at least one of the bottoms, between the group of high-modulus reinforcing material of pressure overwrap and a group of the layers of low-modulus reinforcing material of protective overwrap; the above shock absorber comprises a rigid profiled frame on the side of protective overwrap and a damping device on the side of the pressure overwrap which are interconnected.

Abstract: The invention relates to machine-building. More specifically, it pertains to shell fabrication of airframe parts, which are used in aerospace equipment operating under compound stress. The invention also covers methods and apparatus for the fabrication of the shell structures.The invention aims to improve wall rigidity and strength.A tubular pressure vessel in the form of a composite cylindrical body incorporates a lattice-type frame 1 and external protective cover 2; the grid frame is made by winding a layered system 3 of helical 4, longitudinal 5, girth 6, and oblique transition strips 14 linking the girth strips 6; the pattern forms interleaved stiffening ribs 8, 9, 10, 15. The winding is applied to the mandrel, the core 17 is covered with thermostabilized flexible plates 19 with a web of grooves 23, 24, 25, 26 for imbedding a matching pattern of strips 6,4,5, and 14.
