    Abstract: The present invention relate to a surge control method for a gas turbine engine (10). The method comprises a step of providing a gas turbine engine (10) including a compressor (20), a combustor (30) which is located downstream of the compressor (20) and has a hot gas path, and a turbine (40) which is located downstream of the combustor (30) and has a hot gas path. The method further also comprises steps of monitoring the gas turbine engine (10) for a potential surge state; controlling an air flow from the compressor (20) based on the monitoring in order to avoid the surge state; and directing the air flow to at least one of the hot gas paths in order to bypass at least a part of the combustor (30).

    Abstract: PURPOSE: An axial compressor and a fluid stabilization controlling method thereof are provided to reduce power consumption required for controlling a stall and to minimize an usage of high pressure air by properly controlling an air jetting method for controlling the stall. CONSTITUTION: An axial compressor comprises a case, an axial impeller, and a stall controlling unit(150). A plurality of static blades is comprised in the inner surface of the case. The axial impeller is axis-rotated in the inside of the case and a plurality of dynamic blades is arranged between the static blades in a height direction. The stall controlling unit supplies compressed air to the inside of the case where the axial impeller is rotated at a set time and flow rate so that the stall possible to be generated when the axial impeller is rotated is controlled.

    Abstract: PURPOSE: A compressor is provided to stabilize the performance of a compressor by improving surge margin and choke flow. CONSTITUTION: A compressor includes an impeller wheel(1) mounted in a housing(2) forming an intake part and an exhaust part(6). The intake part includes an outer tubular wall(7) and an inner tubular wall(9) extending upward in the outer tubular wall and forming an inducer part(10). A round gas flow passage(11) is formed between the inner tubular wall and the outer tubular wall. The upper end of the round gas passage is communicated with an intake port or the inducer part of the intake part. At least one lower hole(13) is communicated between the lower portion of the round flow passage and an impeller. The length of the inner tubular wall is L2 extending upward from the lower hole. L2/D is larger than 0.6.
