MEASURING DEVICE OF HINGE MOMENT ACTING ON CONTROL SURFACE OF AIR VEHICLE

摘要

The present invention relates to an apparatus for measuring a hinge torque of a control surface of an aircraft. The apparatus comprises: a planar control surface; a support of which an upper end is connected to an installation hole formed along a central shaft of the control surface through a hinge; and a servo motor connected with the control surface. The present invention removes faults of a hinge torque measurement method using an existing flexure or a pin balance to reduce manufacturing costs of a model of a wind tunnel test corresponding to various angles of the control surface required by the wind tunnel test requirements and minimize a position change of the control surface due to the time required for replacing the model and labor cuts and wind pressure so as to accurately and rapidly measure the hinge torque during the wind tunnel test.
