Transportable three-dimensional calibration wind tunnel system, verification method of flight control system using said system and flight simulator using said system |
摘要 |
A transportable three-dimensional calibration wind tunnel system is comprised of a small wind tunnel portion for creating a three-dimensional calibration air having a suitable wind velocity, and a two-axis rotational deformation device portion for causing said wind tunnel portion to effect a conical motion with a nozzle blow port being an apex to suitably change a flow angle. The two-axis rotational deformation device is comprised of a beta -angle rotational deformation device having a beta -angle deformation base supported to be rotated horizontally, and a alpha -angle rotational deformation device having a alpha -angle deformation base supported to be rotated vertically. A rotational axis of the alpha -angle deformation base, a rotational axis of the beta -angle deformation base and a center axis of the small wind tunnel portion are arranged so that they intersect at a point. In a method for the verification of a flight control system of an aircraft using the transportable three-dimensional calibration wind tunnel system, the nozzle blow port of the three-dimensional calibration wind tunnel system is positioned at the extreme end of an air data sensor probe provided on the aircraft, and the three-dimensional calibration wind tunnel system and an on-board control computer of the aircraft are connected to an out-board control computer so that a suitable three-dimensional airflow is generated by the three-dimensional calibration wind tunnel system to verify the operation and function of the control surface in the stopped state on the ground.
