COOLING SYSTEM FOR GAS TURBINE ENGINE HAVING IMPROVED CORE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a cooling system particularly associated to a core system, in gas turbine engine design having the improved core system instead of a high pressure system of a conventional gas turbine engine.;SOLUTION: This invention discloses the gas turbine engine including the core system 45 arranged on the downstream side of a booster compressor 20, a low pressure turbine 36 communicating in a flow with the core system 45, arranged on its downstream side and used for supplying motive power to a first driving shaft 40, and a system 58 used as a cooling fluid before fuel 64 is supplied to a combustion system 46 and cooling the combustion system 46. The core system also includes an intermediate compressor 47 communicating in a flow with the compressor 20 connected to a second driving shaft 69 and positioned on its downstream side, and an intermediate turbine 49 communicating in a flow with a working fluid 48 and positioned on the downstream side of the combustion system 46.;COPYRIGHT: (C)2006,JPO&NCIPI
