Abstract: 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.

Abstract translation: 叶片具有从燕尾径向向外延伸的翼型件。 当叶片安装在转子内时，燕尾形的边缘将处于叶片的周向侧。 当转子叶片安装在转子中时，燕尾形的底面将向内径向向内，并且形成为使得底表面的周向中心部分比圆周边缘径向厚。 还描述了风扇和燃气涡轮发动机。

Abstract: The present disclosure relates generally to a fan blade assembly. In an embodiment, the fan blade assembly includes an airfoil having a forward edge covered by a sheath. The airfoil and the sheath are made from dissimilar conductive materials. A nonconductive coating is applied the an airfoil contact surface of the sheath before it is bonded to the leading edge of the airfoil.
