Title
(EN) A GAS TURBINE ENGINE INTEGRALLY BLADED ROTOR WITH ASYMMETRICAL TRENCH FILLETS
(FR) ROTOR AUBAGÉ MONOBLOC DE MOTEUR À TURBINE À GAZ COMPRENANT DES FILETS DE TRANCHÉES ASYMÉTRIQUES
Abstract
(EN) An integrally bladed rotor includes a rotor that has a rim that provides an inner flow surface. Circumferentially spaced apart radially extending airfoils integrally with and from the rotor and joined by an airfoil fillet. An asymmetrical trench is provided in the rim between adjacent airfoils.
(FR) Un rotor aubagé monobloc comprend un rotor qui comprend un rebord qui fournit une surface d'écoulement intérieure. Il comprend également des surfaces portantes espacées sur la circonférence et s'étendant radialement depuis le rotor, d'un seul tenant avec celui-ci, et jointes par un filet de surface portante. Une tranchée asymétrique est prévue dans le rebord entre les surfaces portantes adjacentes.
