Title (EN) TURBOMACHINE WITH STARTER MOTOR WITH REVERSIBLE VENTILATION, AND ASSOCIATED COOLING METHOD
(FR) TURBOMACHINE À MOTEUR DE DÉMARRAGE À VENTILATION RÉVERSIBLE, PROCÉDÉ DE REFROIDISSEMENT ASSOCIÉ
Abstract:
(EN) The invention concerns a helicopter turbomachine, comprising an electric starter motor (20) configured to rotate a drive shaft (12), a heat sink (26) for cooling the electric motor and a ventilation wheel (28) driven by the electric motor, characterised in that the ventilation wheel (28) is reversible, the turbomachine comprises an overrunning clutch (22) configured to transmit the torque from the electric motor (20) to the drive shaft (12), the electric motor (20) is configured such that, in the first direction of rotation, it rotates the drive shaft (12) and the ventilation wheel (28) so as to generate an air flow through the heat sink (26) in a direct direction, and, in the reverse direction of rotation, it rotates only the ventilation wheel (28) so as to generate an air flow through the heat sink (26) in a direction opposite the direct direction.
(FR) L'invention concerne une turbomachine d'hélicoptère, comprenant un moteur (20) électrique de démarrage configuré pour entraîner en rotation un arbre (12) d'entraînement, un dissipateur (26) thermique de refroidissement du moteur électrique et une roue (28) de ventilation entraînée par le moteur électrique, caractérisée en ce que la roue (28) de ventilation est réversible, la turbomachine comprend une roue (22) libre configurée pour transmettre le couple du moteur (20) électrique à l'arbre (12) d'entraînement, le moteur (20) électrique est configuré pour dans le premier sens de rotation, entraîner d'une part l'arbre (12) d'entraînement et d'autre part la roue (28) de ventilation de sorte à générer un flux d'air à travers le dissipateur (26) thermique dans un sens direct, et dans le sens inverse de rotation, entraîner uniquement la roue (28) de ventilation de sorte à générer un flux d'air à travers le dissipateur (26) thermique dans un sens opposé au sens direct.
