PROBLEM TO BE SOLVED: To improve cooling efficiency by providing a plurality of division rooms receiving an electric constitutional element, and guiding a cooling fluid to the division room along around the electric constitutional element, in an air flow cooling system cooling the electric constitutional element also supplying a fluid for combustion to a gas turbine engine. SOLUTION: An air flow cooling system 10 is provided with an enclosure 12 arranging a gas turbine engine 14 and an electric machine 16 in the inside, the enclosure 12 has an inlet opening part 30 arranging a filter 32, in one side. The enclosure 12 is distributed to a plurality of division rooms 34, combustion air 50 flowing in via the filter 32 is partly divided in a first division room 36 and made to communicate with a second division room 38 through a plurality of openings 42. A separate part of the air 50 passes through a heat exchanger 18 from a first opening 66 to be advance into a third division room 60, partly the air passing through the first opening 66 is advanced into a forth division room 88, thereafter all the air is introduced to a compressor section 82. |
