Noise Reducing Gas Turbine Engine Airfoil
First Claim
1. A noise reducing airfoil defining a span extending between a root and a tip and a chord at each point along the span extending between a leading edge and a trailing edge, the airfoil comprising:
- a pressure side;
a suction side; and
a trailing edge sheath, defining an outer surface, coupled to the trailing edge of the airfoil and extending at least partially along the chord on the pressure and suction sides at each point along the span within the trailing edge sheath, wherein the trailing edge sheath defines a fluid passageway extending along at least a portion of the span, and wherein the trailing edge sheath defines at least one aperture on at least one of the pressure side, the suction side, or trailing edge fluidly coupling the fluid passageway to the outer surface.

Abstract
A noise reducing airfoil defining a span extending between a root and a tip and a chord at each point along the span extending between a leading edge and a trailing edge. The airfoil includes a pressure side, a suction side, and a trailing edge sheath including an outer surface coupled to the trailing edge of the airfoil. The trailing edge sheath extends at least partially along the chord on the pressure and suction sides at each point along the span within the trailing edge sheath. The trailing edge sheath defines a fluid passageway extending along at least a portion of the span. Further, the trailing edge sheath defines at least one aperture on at least one of the pressure side, the suction side, or trailing edge fluidly coupling the fluid passageway to the outer surface.
