WORK COMBINED WITH STU DISPOSE OF AIRCRAFT TURBINE ENGINE FOR VARIABLE CONDITIONS

V.Т. Matveenko, V.А. Ocheretyaniy

The results of research and development of combined gas turbine (СGTE) with air utilizing turbines at varying operating conditions are presents. The paper discusses various design schemes of the formation of СGTE with recycling air turbine (AT) in combination with primary GTE, which can be a simple cycle, as well as double-circuit design. It is shown that in both the nominal and variable loads the effective efficiency СGTE is higher than in the GT of a simple cycle. The choice of the constructive scheme СGTE with AT depends on the application installation and conditions of its functioning. To work in all ranges to the main СGTE turbofan gas turbine engine is more suited.

Key words: gas turbine engine, combined gas turbine power plant, recycled air turbine cogeneration.
