Abstract

La présente invention concerne un procédé pour arrêter un moteur (10) de giravion (1) en survitesse, ledit moteur (10) comprenant un générateur de gaz (11) et un ensemble de puissance (19). Lorsque ledit moteur (10) est en fonctionnement. on établit une loi donnant une dérivée limite qui varie en fonction de la vitesse de rotation de l'ensemble de puissance (19). On mesure la vitesse de rotation dite « vitesse courante » atteinte par l'ensemble de puissance et on détermine la dérivée par rapport au temps de ladite vitesse de rotation dite « dérivée courante. On arrête automatiquement ledit moteur (10) lorsque la dérivée limite correspondant à la vitesse courante selon ladite loi (100) est inférieure ou égale à la dérivée courante.
