To the question of the development of highly efficient micro-turbines with independent rotational speeds of the compressor and turbine.

Abstract

In the article the problem arising in the design of small-size turbo-generators (mhtg) in selecting the optimal thermal circuit and layout to maximize the efficiency of the installation. The experience of work on the creation of small mgtg, the features created by the installation and effectiveness of use. Outlines the key ways to improve the efficiency of the installation - the use of regenerative heating air supply before combustion, the increase of gas temperature before the turbine, the achievement of the optimum degree of pressure increase. Marked limitations in efficiency optimization, recommendations on the choice of scheme and layout mgtg, the benefits of the proposed scheme and layout.
