1. An airfoil comprising:
- a pressure surface and a suction surface extending from a root section of the airfoil to a tip section of the airfoil;
a leading edge and a trailing edge defining a chord length of the airfoil therebetween; and
a tip shelf formed along the tip section of the airfoil between the pressure surface and a tip shelf wall, wherein the tip shelf wall is spaced between the pressure surface and the suction surface, wherein the tip shelf extends from within 10% of the chord length measured from the leading edge to within 10% of the chord length measured from the trailing edge.

Abstract
An airfoil includes a pressure surface and a suction surface extending from a root section of the airfoil to a tip section of the airfoil. The airfoil also includes a leading edge and a trailing edge defining a chord length of the airfoil therebetween. The airfoil further includes a tip shelf formed along the tip section of the airfoil between the pressure surface and a tip shelf wall. The tip shelf wall is spaced between the pressure surface and the suction surface and the tip shelf extends from within 10% of the chord length measured from the leading edge to within 10% of the chord length measured from the trailing edge.

15. A gas turbine engine blade comprising:
-
an airfoil comprising convex and concave surfaces extending from a root section to a tip section and from a leading edge to a trailing edge, the leading and trailing edges defining a chord length therebetween; and a tip shelf defining an open perimeter recess between the concave surface and a tip shelf wall, wherein the tip shelf wall is spaced between the convex surface and the concave surface, wherein the open perimeter recess extends from a region within 5% of the chord length measured from the leading edge of the airfoil to a region within 5% of the chord length measured from the trailing edge of the airfoil. - View Dependent Claims (16, 17, 18, 19, 20)
