Рекуперация авиационных газотурбинных двигателей для решения проблем наземного транспорта и энергетики

Abstract

The article presents an example of recuperation of aircraft gas turbine engines (GTE), adapted for use on ground conditions, used both for pipeline transportation of liquid, and gas forms which are oil or gas pipelines, and for power engineering. GTE due to its advanced qualities, such as compactness, specific energy intensity, throttle response, etc., have found a wide application in the form of power units for ground-based purposes. However, questions remain about their reliability and durability under these conditions, one of the approaches for solving these issues is the recuperation of the working process of the aircraft GTE. The paper presents a methodology for the implementation of a variant of the structural layout for recuperation of the power plant for the presented type. The principle of recuperation а GTE consists of the application of methods for converting, transferring, or redirecting heat in engine units Thus the goal of the presented work is to create a comparative methodology for mathematical modeling of the knownthermodynamic cycle of operation of a GTE and cycle with recuperation. The proposed research is aimed to study the option of using the energy of engine exhaust gases through a specially designed (selected) heat exchanger, the main work is the recognition and calculation of the actual state of the thermal potential in the engine, as well as the possibility of using the engine parameters averaged over the section to build a mathematical model for analyzing the performance of GTE cycles with or without heat recovery
