METHOD TO INCREASE THE RESOURCE OF A GAS TURBINE ENGINE ACCORDING TO THE NUMBER OF LAUNCHES

摘要

FIELD: motors and pumps.;SUBSTANCE: invention relates to air engine building, namely to methods of increasing resource and basic parameters by introducing into engine design turbine of cooling systems. Before cold scrolling and starting of engine, hot air is supplied with parameters of cooling air of this engine from external source of hot air into gas-air path from the side of a nozzle towards turbine and heated for 6…12 minutes, then supply of hot air is switched off, after which engine is started, auxiliary gas turbine engine can be used as external source of hot air.;EFFECT: increase life of engine by the number of starts, respectively for low cycle fatigue, by reducing temperature difference in blades and discs of turbine due to their preheating with hot air.;1 cl, 2 dwg
