Description

technical field [0001] The invention relates to a test method for a hydraulic actuator of a gas turbine, an electronic terminal and a storage medium, and belongs to the field of gas turbines. Background technique [0002] A gas turbine is mainly composed of three major components: a compressor, a combustion chamber, and a turbine; the air is compressed in the compressor, and the resulting high-temperature and high-pressure air is mixed with fuel in the combustion chamber for combustion, and the high-temperature and high-pressure flue gas produced by combustion is discharged in the turbine. The medium expansion works to make the gas turbine rotate at a high speed. The Chinese invention patent with the application number 201910168285.2 discloses a hydraulic actuator and a gas turbine. The hydraulic actuator of the gas turbine is described in detail in this patent document. For details not described in this patent, please refer to this patent document and related documents. co...
