摘要： PURPOSE: To enlarge an operation range and increase efficiency through prevention of the occurrence of surging, by a method wherein a part of fluid is recovered to an vortex chamber formed in a region, where a U-turn part is enlarged, and is joined with a main current from a U-turn outlet to guide it to a return channel for deceleration boosting.
CONSTITUTION: The width of a flow passage is increased from B
4 to B
5 in a range from the inlet to the outlet of a U-turn part 8 in a return channel 10, and a section Q
1 in a drawing forms a vortex chamber 17. A part of fluid is recovered to the vortex chamber 17, and is joined at the outlet of the U-turn part 8 with a main current flowing through the U-turn part 8 to guide it to the return channel 10 where the fluid is further decelerated and boosted. This constitution enables provision of a centrifugal compressor in which speed energy is also recovered at the vortex chamber 17 formed in the U-turn part 8, surging is less apt to occur, an operation range is increased, and operation can be effected with high efficiency.

SOLUTION: A turbine 1 is rotary-driven by a motor 5 connected with the turbine 1, and air is pressure-transferred to a combustor by an air compressor 3 interlocking with the turbine 1. When the turbine 1 reaches a predetermined rotational frequency, the supply of fuel to a combustor 2 is started, and an ignition action of fuel-air mixture is started in the combustor 2. While the ignition action of the mixture is performed at least in the combustor 2, the rotational frequency of the turbine 1 is increased, and the supply volume of the fuel to the combustor 2 is increased.
