A commanded control signal is compared against an adaptive control signal in order to detect a rotor strike by a rotor included in an aircraft, wherein the adaptive control signal is associated with controlling the rotor and the adaptive control signal varies based at least in part on the commanded control signal and state information associated with the rotor. In response to detecting the rotor strike, a control signal to the rotor is adjusted in order to reduce a striking force associated with the rotor.

    L'invention concerne un signal de commande commandé qui est comparé à un signal de commande adaptatif afin de détecter un impact de rotor par un rotor se trouvant dans un aéronef, le signal de commande adaptatif étant associé à la commande du rotor et le signal de commande adaptatif variant en fonction, au moins en partie, du signal de commande commandé et des informations d'état associées au rotor. En réponse à la détection de l'impact de rotor, un signal de commande au rotor est ajusté afin de réduire une force d'impact associée au rotor.
