ガスタービンエンジン
Document Type and Number:
Japanese Patent JP6734584
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas turbine engine of high combustion efficiency, low fuel consumption, and high output.SOLUTION: A gas turbine engine 1 includes a centrifugal compressor 3 provided with a diffuser space 33, and an annular combustor 4. An outer cylinder 42o having a hollow conical shape is disposed on a combustion cylinder 42 of the combustor 4. A front wall 42f of the combustion cylinder 42 is provided with an outer peripheral edge portion projecting to a circumferential outer side with respect to a projection face formed in a case of projecting an outlet portion 42r of the combustion cylinder 42 to the front wall 42f. A plurality of fuel inflow ports 48 are formed on the outer peripheral edge portion in a circumferential direction, and a tip 46t of a fuel injection valve 46 is inserted to the fuel inflow ports 48. The diffuser space 33 is expanded in an outer peripheral direction from an impeller 31 to the outer peripheral edge portion and an upstream-side position of the fuel inflow ports 48. An inclination angle θ of the outer cylinder 42o is preferably 15°-30°, and further swirlers 49 are preferably disposed on the fuel inflow ports 48.SELECTED DRAWING: Figure 1
