Поиск путей модернизации газотурбинной установки с трёхкаскадным газогенератором и свободной турбиной

Abstract

The article describes the suggestions for upgrading the gas turbine power plant (increasing its effective efficiency from 36% to 40%) using the computer-aided system ASTRA, covering the conceptual design stage of gas turbine development. The increase in effective efficiency has been obtained mainly by correcting the flow capacities thus providing more efficient joint operation of the engine elements. Area values of the characteristic cross-sections of the engine turbines as well as the angular velocities of engine spools have been corrected with an account to capability to provide high efficiency of engine elements (using the Smith diagram).
