Abstract
An unducted airfoil assembly includes an airfoil having spaced-apart pressure and suction sides extending radially in span from a root to a tip, and extending axially in chord between spaced apart leading and trailing edges. The airfoil defines a forward-most axial point and is arranged around a longitudinal axis and rotates about the longitudinal axis in a rotational direction. A tip leading edge of the airfoil is circumferentially offset in a direction opposite the rotational direction relative to a circumferential location of the forward-most axial point.
Claims7
An unducted airfoil assembly, comprising:
- an airfoil having spaced-apart pressure and suction sides extending radially in span from a root to a tip, and extending axially in chord between spaced apart leading and trailing edges, and wherein the airfoil comprises a forward-most axial point located between the root and the tip, and wherein the airfoil defines a tip portion extending radially from the forward-most axial point to the tip;
- and
- wherein a thickness of the airfoil is defined as a distance measured between the pressure side and the suction side, and wherein a maximum thickness for at least 50% of a radial extent of the tip portion for a chord extending from the leading edge to the trailing edge is located forward of 0.40 chord fraction.
