Abstract:
A flight control apparatus for helicopters, comprising:a control unit to be operated by a pilot; a steering mechanism for generating an aerodynamic control force; a control transmission mechanism for mechanically transmitting a control amount from the control unit to the steering mechanism, to thereby drive the steering mechanism; an amount-of-control sensor for detecting the control amount from the control unit and generating a control signal; a flight control law calculation unit for calculating a flight control model of a helicopter based on the control signal and a predetermined flight control mode, and for generating a driving signal for the steering mechanism; a difference calculation unit for subtracting the control signal from the driving signal so as to generate a difference signal; and a servo actuator unit for adding a control difference amount to the control amount transmitted via the control transmission mechanism to generate a driving amount, wherein the control difference amount corresponds to the difference signal.
