HINGE MOMENT OF THE REJECTED SURFACE MEASUREMENT DEVICE Russian patent published in 2019 - IPC G01M9/04 

FIELD: measurement technology.

SUBSTANCE: invention relates to the field of aeromechanical measurements and can be used to measure the hinge moments acting on the controls and takeoff and landing mechanization of aerodynamic models of aircraft in the flow of the wind tunnel. Device contains a control mechanism for a deflected surface, built according to the two-beam scheme of strain-gauge weigher, including a measuring head and a shank. Strain-gauge weigher are installed on a deflected surface, the measuring head of strain-gauge weigher is rigidly attached to a deflected surface and located on its axis of rotation. Strain-gauge weigher tail is connected to the deflecting surface control mechanism by means of a fork.

EFFECT: technical result consists in the possibility of measuring the hinge moment on the deflected surfaces of aerodynamic models with continuous control of the deviation in an aerodynamic experiment.
