Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a compressor including a compressor vane angle changing structure, and a gas turbine including the compressor vane angle changing structure,

The present invention relates to a compressor and a gas turbine including the same.

A gas turbine is a power engine that mixes and combusts compressed air and fuel compressed in a compressor and rotates the turbine with hot gases generated by combustion. Gas turbines are used to drive generators, aircraft, ships, trains, and so on.

Generally, a gas turbine includes a compressor, a combustor, and a turbine. The compressor sucks the external air, compresses it, and transfers it to the combustor. The compressed air in the compressor is in a state of high pressure and high temperature. The combustor mixes the fuel and the compressed air introduced from the compressor and burns them. The combustion gas generated by the combustion is discharged to the turbine. The combustion gas causes the turbine blades inside the turbine to rotate, thereby generating power. The generated power is used in various fields such as power generation, driving of machinery and the like.

1 is a perspective view showing a gas turbine according to the prior art, and Fig. 2 is a partial sectional view showing the compressor, combustor and turbine portion shown in Fig.

The compressor 1100 according to the prior art includes a rotor 1120 with a compressor disk 1110 mounted thereon, a compressor blade 1130 mounted on the outer periphery of the compressor disk 1110, a compressor disk 1110 and a compressor blade 1130, And a compressor vane 1140 mounted on the inner surface of the compressor casing 1150. The compressor casing 1150 includes:

In the case of the compressor according to the related art, the compressor blades 1130 and the compressor vanes 1140 are modified to various structures in order to effectively compress air sucked from the outside.

Even if compressor blades and compressor vanes of various structures are applied, there is a limit in order to induce the flow of compressed air more effectively.

In order to solve this problem, as shown in FIG. 3, the angle of the compressor vane is adjusted by using a compressor vane angle changing device having a specific structure.

However, at the rear end of the compressor, the size of the compressor vane is small and there is not enough space for arranging the angle changing device, so that the stroke of the compressor vane mounted at the rear end of the compressor can not be changed.

Furthermore, in order to change the angle of the compressor vane mounted at the rear end of the compressor for testing the rig, there is a problem that a compressor vane formed at a new angle must be separately manufactured.

Therefore, as described above, there is a need for a technique capable of solving the problems of the prior art.
