A method and system for gas turbine engine off-load starting includes using a starter (12) connected to a rotor (22) of a gas turbine engine to start the gas turbine engine while terminating or reducing torque transmission from the starter to accessory devices (70) by means of completely or partially declutching a magnetic fluid clutch (26) until a gas turbine engine starting cycle is completed and the gas turbine engine is operating under a self- sustaining condition.
L'invention concerne un procédé et un système permettant un démarrage à charge réduite d'une turbine à gaz. Le procédé consiste à utiliser un démarreur (12) relié à un rotor (22) d'une turbine à gaz pour faire démarrer la turbine à gaz tout en supprimant ou réduisant la transmission du couple entre le démarreur et les dispositifs accessoires (70) au moyen d'un débrayage complet ou partiel d'un embrayage à fluide magnétique (26) jusqu'à la fin d'un cycle de démarrage de la turbine à gaz et jusqu'à l'entrée de cette dernière en mode de fonctionnement autonome.
