Abstract

A gas turbine engine includes a fan section, a compressor section and a turbine section, one of which includes an airfoil. The airfoil includes pressure and suction sides extending in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip. The airfoil has a maximum chord length projection that is not in an axial view.

Claims (18)

1. A gas turbine engine comprising:

a combustor section arranged between a compressor section and a turbine section that extend in an axial direction;

a fan section arranged upstream from the compressor section; and

an airfoil that is arranged in one of the fan section, the compressor section and the turbine section, the airfoil includes pressure and suction sides extending in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip, wherein the airfoil has a chord length that is projected onto a plane from various views, and the plane is perpendicular to a viewing direction which corresponds to the various views, the plane is parallel with the axial direction in a 0° view, the various views include the 0° view which projects into an axial plane in the axial direction, a 90° view which projects into a tangential plane in a tangential direction normal to the axial direction, and views between the 0° and 90° views, wherein the maximum chord length projection is in about a 40° view that is in a range of 60% to 70% span position, and wherein the radial direction is normal to the axial and tangential directions.

2. The gas turbine engine according to claim 1 , wherein the airfoil is a fan blade in the fan section.

3. The gas turbine engine according to claim 2 , wherein the fan blade is a composite blade.

4. The gas turbine engine according to claim 3 , wherein the composite blade is a swept blade.

5. The gas turbine engine according to claim 1 , wherein the fan section has a fan pressure ratio of less than or equal to 1.5.

6. The gas turbine engine according to claim 1 , wherein the engine has a bypass ratio of greater than 6.

7. A gas turbine engine comprising:

a combustor section arranged between a compressor section and a turbine section that extend in an axial direction;

a fan section arranged upstream from the compressor section; and

an airfoil that is arranged in one of the fan section, the compressor section and the turbine section, the airfoil includes pressure and suction sides extending in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip, wherein the airfoil has a chord length that is projected onto a plane from various views, and the plane is perpendicular to a viewing direction which corresponds to the various views, the plane is parallel with the axial direction in a 0° view, the various views include the 0° view which projects into an axial plane in the axial direction, a 90° view which projects into a tangential plane in a tangential direction normal to the axial direction, and views between the 0° and 90° views, wherein the maximum chord length projection is in about a 50° view that is at the 100% span position, and wherein the radial direction is normal to the axial and tangential directions.

8. The gas turbine engine according to claim 7 , wherein the airfoil is a fan blade in the fan section.

9. The gas turbine engine according to claim 8 , wherein the fan blade is a composite blade.

10. The gas turbine engine according to claim 9 , wherein the composite blade is a swept blade.

11. The gas turbine engine according to claim 7 , wherein the fan section has a fan pressure ratio of less than or equal to 1.5.

12. The gas turbine engine according to claim 7 , wherein the engine has a bypass ratio of greater than 6.
