Improving the efficiency of aviation turbo-shaft gas turbine engine by using heat recovery

Abstract

 One of the ways to improve the efficiency of turboshaft gas turbine engines with a free turbine (GTE PT) is the heat recovery of exhaust gases. Computer models of turboshaft engines with heat recovery (GTE PTR) developed in the ASTRA system tools allowed to solve problems of nonlinear optimization of the parameters of their working process, to determine the most rational schemes depending on the purpose and operating conditions of the engine. The article presents, the results of a research on the effect of the efficiency of a turbo-shaft gas turbine engine of the working process parameters and the heat exchanger effectiveness, as well as, the results of the optimization according to the effective efficiency of a turbo-shaft gas turbine engine on the working process parameters
