Main trends of perfection of gas-turbine engines (GTE) of transport plants by application of principles of the cascade pressure exchange (CPE) for air compression in the working cycle of gas-turbine plant have been analyzed. The principle of action and performances of work of heat compressor CPE realizing compression of working body on the whole at the expense straight convert inputting heat in disposing work of torrent with insignificant distraction mechanics work from shaft selection of power has been described. The results of computational investigation of four variants of the GTE working process organization on the basis of the two-staged compression assembly with intermediate cooling and heating of air-gas medium have been adduced. Application of units CPE in the capacity of compressing stage GTE opens the prospect of adaptations GTE performance by conditions of work in the capacity of forcing units of overland transport.
