Pressure vessels are used in aircraft and space engineering among other constructive elements. As usual they have cylindrical or spherical shape. The application …eld makes it extremely important for them to meet the requirement of minimal weight.

The pro…led cylinder structure shown in Fig. 163 is proposed. The vessel consists of several cylindrical sections connected by radial walls. As the radius of the cylindrical sections is less than the radius of the ordinary cylinder with the same volume then stresses in them will be less too. So one can hope that in spite of weight increase due to the radial walls the whole weight of the structure will be lower. To what extent are these expectations valid?
