The invention relates to a movable vane of a compressor, in particular to a primary movable vane of a transonic compressor for a high-rotation-speed gas turbine and aims to solve the problem that the existing primary movable vanes of transonic compressors for high-rotation-speed gas turbines are low in efficiency, short in service life and affects safety operation of the compressors. A section B-B is defined as a standard face, section geometric data, from a root to a top, of a vane operating part 1 is as follows: section height H from section A-A to section W-W is -6.10mm-179.28mm, axial width B is 66.71-40.35mm, chord length is 69.65-91.41mm, bending angle alpha is 17.331-65.096 degrees, the largest thickness of modeled lines is 10.27-2.22mm, gas outlet edge thickness DE of a position GH distant from a gas outlet edge is 1.54-0.34mm, and total length L of the vane operating part is 168.65mm. The primary movable vane is applicable to the transonic compressor for the high-rotation-speed gas turbine.
