【 摘 要 】

As an illustration of the design features of composite winding pressure gas tanks, the article provides three illustrative simple examples: 1. calculation of the critical pressure in composite cylinders according to the layer-by-layer analysis scheme for pairs of symmetrically wound layers; 2. assessment of the permissible wall thickness by a rational design based on the "thread analogy"; 3. analysis of the effectiveness of multi-cavity spherical gas tank, which are located in each other-box in a box model ("nested doll").
