Description

technical field [0001] The present application relates to but not limited to the technical field of aircraft total pressure measurement, especially a correction method and computer equipment for the measurement error of a total pressure sensor. Background technique [0002] During the flight of the aircraft, the usable range of angle of attack is generally relatively large, and usually when this range of angle of attack corresponds to the range of local angle of attack where the full pressure sensor is located, the range will become even larger. When the aircraft is flying at a high angle of attack, the local angle of attack at the location of the total pressure sensor is beyond the accuracy guarantee range of the total pressure sensor measurement error, resulting in a large loss in total pressure measurement, resulting in the occurrence of air space problems during high angle of attack flight. The inaccurate measurement of atmospheric data information such as speed and alti...
