Abstract

Le turbopropulseur (16) pour aéronef comprend • un arbre de propulsion (18), • une hélice de propulsion (17) montée sur l’arbre de propulsion (18), • un module d’entraînement (19) relié à l’arbre de propulsion (18), comportant un arbre d’entraînement (20) relié à une deuxième extrémité de l’arbre de propulsion (18), et • un premier capteur (24) de vitesse de rotation configuré pour mesurer une première vitesse de rotation de l’hélice de propulsion (17). Le module d’entraînement (19) comprend • un seul deuxième capteur (33) de vitesse de rotation configuré pour mesurer une deuxième vitesse de rotation de l’arbre d’entraînement (20), et • des moyens de commande pour détecter une casse de l’arbre de propulsion (18) et pour détecter une défaillance de la protection en survitesse de l’arbre de propulsion (18). Figure pour l’abrégé : Fig 3The turboprop engine (16) for an aircraft comprises • a propulsion shaft (18), • a propulsion propeller (17) mounted on the propulsion shaft (18), • a drive module (19) connected to the shaft propulsion (18), comprising a drive shaft (20) connected to a second end of the propulsion shaft (18), and • a first rotation speed sensor (24) configured to measure a first rotation speed of the propulsion propeller (17). The drive module (19) comprises • a single second rotation speed sensor (33) configured to measure a second rotation speed of the drive shaft (20), and • control means for detecting breakage of the propulsion shaft (18) and to detect a failure of the overspeed protection of the propulsion shaft (18).
