The cascade exchanger and new principles of the organization of working process of the sag-turbine engine

Klyus O., Krajniuk A.

Journal of Polish CIMAC

2012

Vol. 7, no 1

87-97

Main trends of perfection of gas-turbine engines (GTE) 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 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. Possibility and reserve of raise of power efficiency of GTE with the CPE at the expense of increase in the maximum temperature of the cycle and recuperation of the residual heat of compressing gases have been shown.

Thermal compressor of cascade exchange by pressure

Krajniuk A.

Transport Problems

2010

T. 5, z. 1

15-22

A new method of organization of working cycle of device of direct transformation of heat in the located work of compression of air, based on principle of cascade exchange by pressure, is exposed; the results of pre-selection of basic dimensional and structural parameters of thermal compressor of cascade exchange by pressure are adduced; some special features of its working process are considered; main directions of perfection of working cycle of thermal compressors of cascade exchange of pressure are shown.
