[0002] At present, the infrared temperature measurement system provides an image of the temperature field based on the premise that the rotational speed is known. In actual situations, the engine rotational speed cannot be completely and accurately measured within the test time. After comparison and observation, under the maximum operating state of the engine, when the rotational speed occurs 1 / When the constant offset is 10000, the temperature field image will be significantly distorted
[0003] The common means of measuring speed is multi-stage gears. The disadvantage of this scheme is: when using multi-stage gears to measure the speed of high-pressure turbine, due to the vibration between gears, electromagnetic interference, design defects of tachometer phase-locked loop, etc., the measured value has certain deviations. small error

Description
Technical field [0001] This application relates to the technical field of aeroengines, and specifically provides a method for processing turbine blade temperature fields. Background technique [0002] At present, the infrared temperature measurement system provides temperature field images based on the premise that the speed is known. In actual conditions, the engine speed cannot be measured completely and accurately within the test time. After comparison and observation, under the maximum working state of the engine, when the speed occurs 1 / At a constant offset of 10,000, the temperature field image will be significantly distorted. [0003] The common method for measuring speed is multi-stage gears. The disadvantage of this scheme is that when multi-stage gears are used to measure the speed of high-pressure turbines, the measured value has a certain value due to the vibration between gears, electromagnetic interference, and design defects of the tachometer phase-locked loop Mino...
