AIR INLET GUIDE APPARATUS FOR A GAS TURBINE'S COMPRESSOR

摘要

PURPOSE: An air guide device of a gas turbine compressor is provided to precisely adjust the amount of inflow air to the gas turbine compressor by adjusting rotary angles of each vane of IGV and VGV assemblies. CONSTITUTION: An air guide device of a gas turbine compressor comprises a frame(310), an actuator(320), a rotary shaft(330), an actuator connection arm, an IGV connection arm(350), a VGV connection arm(360a, 360b), an IGV connection link(370), and VGV connection links. The actuator connection arm is connected to one side of the rotary shaft. The actuator connection arm is connected to the operating rod(322) of the actuator. The IGV and VGV connection arms are protruded from other side of the rotary shaft. The IGV connection link links the IGV connection arm and an IGV assembly. The VGV connection links link the VGV connection arm and a VGV assembly.
