Novye shemy i osobennosti rabocego processa gazoturbinnyh dvigatelej na baze kaskadnogo obmennika davleniem

The paper describes the main directions of gas turbines improvement in terms of application of the cascade pressure exchange rules for air compression in the machine�fs working cycle. The final calculation results of the four variants of the working process organization on the base of the two-stage gas turbine compression unit with inter-cooling and heating of the gas medium are presented. Opportunities and provision of energy efficiency increase of cascade pressure exchange gas turbine by increasing the maximum temperature of the circulation and recirculation of waste heat gas compression are shown.
