Aircraft airflow sensor with error correction based on aircraft movement and calibration process of said sensor based on aircraft movement

摘要

An aircraft airflow sensor probe comprising: a vane assembly configured to sense a direction of local airflow external to the aircraft; a shaft configured to rotatably hold the vane assembly and permit rotational movement of the vane assembly; at least one accelerometer configured to detect aircraft movement; a sensor for detecting and outputting a rotational position of the vane assembly; an angle of attack processor configured to determine at least a measured angle of attack of the aircraft based on a rotational position of the vane assembly; The at least one accelerometer is configured to provide aircraft motion data to the angle of attack processor. and the angle of attack processor is further configured to determine a calibration value based on aircraft motion data provided by the at least one accelerometer and output a calibrated angle of attack of the aircraft.
