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.
