Gas turbine secondary air system rotation test device and test method

The invention specifically discloses a gas turbine secondary air system rotation test device, which comprises an air inlet system and a test bed connected with the air inlet system, wherein the test bed comprises a test box and a rotation transmission mechanism in transmission connection with a test piece. The test method comprises the following steps of mounting a test piece, installing a test piece at one end, far away from the driving motor, of the rotor shaft, wherein the test piece is located in the test box, checking whether the data of each test sensor group is normal or not, carrying out test, replacing different test pieces, and repeating the steps to obtain aerodynamic parameters of different positions. According to the method, the aerodynamic parameters of all parts of the secondary air system of the gas turbine are effectively obtained, and important data support can be provided for design of the gas turbine by obtaining the real and reliable performance parameters of the gas extraction section of
