FIELD: external disturbing forces meters.
SUBSTANCE: meter of external disturbing forces and the moments of these forces acting on the fuselage of a single-rotor helicopter contains a block of absolute angular velocity meters, a device for adjusting the moments of inertia associated with a moment calculator, adders, sensors for the normal and tangential components of the main rotor thrust force, a torque sensor and a thrust sensor tail rotor, calculator of coordinates of the center of gravity of the helicopter, connected in a certain way, as well as six meters of apparent accelerations, two sensors placed on each axis of the helicopter, the outputs of which are connected to the corresponding adders for determining the averages in a pair of accelerations.
EFFECT: simultaneous measurement of moments of external disturbing forces and moments of control forces acting on the fuselage of a single-rotor helicopter along three axes is provided.
