Abstract: A fan blade includes a root including a front surface, a rear surface, a first side surface connected to the front surface and the rear surface, and a second side surface connected to the front surface and the rear surface. The front surface engages the first side surface and the second side surface by one or more blunted surfaces, and the rear surface engages the first side surface and the second side surface by one or more blunted surfaces. A blade extends from the root.

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。
