Abstract: In this current work, the design of a single stage centrifugal compressor as part of a complete small gas turbine coupled directly to high speed permanent magnet running at 60000rpm and developing a maximum electrical power of 60kW is presented. The choice of a radial impeller was considered and the design was based on using a non-linear optimisation code to determine the geometric dimensions of the impeller. Also, the optimum axial length and the flow passage of the impeller were found based on prescribed mean stream velocity. The proposed code was verified and showed quite good agreement with the published data in the open literature. The design of a vaneless diffuser and a volute were considered based on satisfying the governing equations of conservation of mass, momentum, and energy conservation simultaneously. Results showed good agreement with the CFD analysis found in the open literature. This work was motivated by the growing interest in micro-gas turbines for electrical power generation, transport and other applications.

Abstract: This paper is the first part of a series of articles devoted to the researching of the principles designing of the railguns to accelerate the macrobodies. Here the results of comparative analysis of the electrodynamic railgun with increased traction for the acceleration of the large mass bodies are shown. Design of accelerators with multi-blade rotor and coaxial accelerator are illustrated and discussed.
