| description | The invention discloses an embedded wind tunnel free flight test model pose acquisition method, and relates to the technical field of flight tests. The embedded wind tunnel free flight test model poseacquisition method comprises the steps of: carrying out the interception of inertial sensor data according to a preset rule to obtain test effective data which comprises triaxial accelerometer data and triaxial gyroscope output data; performing low-pass filtering on the triaxial accelerometer data to obtain first data, and removing high-frequency vibration interference; performing band elimination filtering on the first data and the output data of the three-axis gyroscope to obtain second data, and removing pulsation interference of a pneumatic airflow; and carrying out recursive pose calculation on the basis of the second data to obtain six-degree-of-freedom pose information of the aircraft model within effective time in the test process.
