FAN BLADE TALL DOVETAIL FOR INDIVIDUALLY BLADED ROTORS |
| 摘要 |
A blade has an airfoil extending radially outwardly of a dovetail. The dovetail has edges that will be at circumferential sides of the blade when the blade is mounted within a rotor. A bottom surface of the dovetail will be radially inward when the rotor blade is mounted in a rotor, and is formed such that a circumferentially central portion of the bottom surface is radially thicker than are circumferential edges. A fan and a gas turbine engine are also described. |

1. A blade comprising:
an airfoil extending radially outwardly of a dovetail, said dovetail having edges that will be at circumferential sides of the blade when the blade is mounted within a rotor; and a bottom surface of the dovetail that will be radially inward when the rotor blade is mounted in a rotor, and said bottom surface being formed such that a circumferentially central portion of said bottom surface is radially thicker than are circumferential edges. |
