TURBOFAN ENGINE WITH GEARED ARCHITECTURE AND LPC BLADE AIRFOILS

TURBOFAN ENGINE WITH GEARED ARCHITECTURE AND LPC BLADE AIRFOILS

An airfoil of a turbine engine includes pressure and suction sides that extend in a radial direction from a 0% span position to a 100% span position. The airfoil has a relationship between a leading edge angle and span position that defines a curve with at least one of a decreasingly negative slope...

Zusammenfassung:An airfoil of a turbine engine includes pressure and suction sides that extend in a radial direction from a 0% span position to a 100% span position. The airfoil has a relationship between a leading edge angle and span position that defines a curve with at least one of a decreasingly negative slope or a positive slope from 80% span to 100% span.
