The following preparatory and intermediate phases were derived: nonlinear physical-mechanical models of layered foundation; the preliminary rotational-planar profile of the foundation for generating 3D solid of revolution of finite element model (Fig.
If [V.sub.n] is the volume for a solid of revolution's frustum, of length L, and end cross sectional areas s at x = [x.sub.1], and S at x = [x.sub.2], generated by the equation [y.sub.2] = [p.sub.n][x.sub.n], where n is a positive integer, then, [V.sub.n] can be expressed in the form
From a physical point of view, it is a homogeneous solid of revolution rotating on a symmetry axis in a vacuum casing with magnetic bearings, which reduces aerostatic and mechanical friction and greatly increases the efficiency of this device.
It is possible to design conformal arrays to fit a three-dimensional shape such as a pyramid, cube or a solid of revolution such as the fuselage of an aircraft.
