AUBE DE MOTEUR À TURBINE À GAZ AYANT UNE INCLINAISON LOCALE VERS L'INTRADOS DE POINTE D'AUBE

摘要

A rotor blade (70) of a gas turbine engine (20) includes a pressure side (88), and a suction side (90) opposite the pressure side and defining a rotor blade profile therebetween, the pressure side and the suction side each extending from a blade root (72) to a blade tip (74). The rotor blade defines a cross-sectional median line (92) midway between the pressure side and the suction side. The cross-sectional median line extends in a generally radial direction from the blade root to a lean point (96) between the blade root and the blade tip. The cross-sectional median line extends off of radial from the lean point to the blade tip, defining a lean of the rotor blade between the lean point and the blade tip.
