Abstract
The invention relates to a method for controlling a rotary wing aircraft with at least one main rotor, comprising a rotor head and rotor blades (), arranged such that each rotor blade () is supported to be able to pivot or twist around the lengthwise axis of its blade on the rotor head and has at least one control flap () that can be deflected. According to the invention, the rotary wing aircraft is controlled solely by changing the respective blade pitch angle (X) by means of changing the flap control angle (Y) of the assigned control flaps () by the resulting blade pitch angle (X) being set by applying the resulting flap angle (Y) to the control flap (), and the flap angle (Y) being computed using an algorithm, the input quantities comprising the flap control angle (Y) depending on the pilot primary control and the flap correction angle (Y) depending on the secondary control.
