Title (EN) SHAFT BREAK DETECTION
(FR) DÉTECTION DE RUPTURE D'ARBRE
Abstract: front page image
(EN) A shaft break detection system (68a) and a method of detecting shaft break for a gas turbine engine. A first indication is calculated from measured rotational speed of a shaft. A second indication (68b) is calculated from the rotational speed. A shaft break signal is generated if both indications are true.
(FR) L'invention concerne un système de détection de rupture d'arbre (68a) et un procédé de détection de rupture d'arbre pour un moteur à turbine à gaz. Une première indication est calculée à partir de la vitesse de rotation mesurée d'un arbre. Une deuxième indication (68b) est calculée à partir de la vitesse de rotation. Un signal de rupture d'arbre est généré si les deux indications sont vraies.
