The paper presents the results of theoretical analysis and experimental studies of power loads acting on the plates of a rotary-plate machine in order to significantly reduce power loads and drive power. Experimental studies of prototypes of RPMs with magnetic pressing of plates, performed according to the method of G. N. Trunov, have shown significant possibilities for reducing the friction of plates on the cylinder, as well as the possibility of using machines with significantly reduced drive power values. A series of micromachines for different rotor diameters are being created using magnetic squeezing devices, which makes it possible to significantly improve the dynamic characteristics of these micromachines, increase their efficiency and outline prospects for further research on improving the designs of RPMs.

Impeller machine is a device in which the flow path carries out the supply (or retraction) of mechanical energy to the flow of a working fluid passing through the machine. To increase the efficiency of impeller machines, it is necessary to use design modern technologies, namely the use of numerical methods for conducting research in the field of gas dynamics, as well as additive manufacturing (AM) for the of both prototypes and production model. AM technologies are deservedly rightly called revolutionary because they give unique possibility for manufacturing products, creating perfect forms, both light and durable. The designers face the challenge of developing a new design methodology, since AM allows the use of the concept of “Complexity For Free”. The “Complexity For Free” conception is based on: complexity of the form; hierarchical complexity; complexity of the material; functional complexity. The new technical items design method according to a functional principle is also investigated.
