发明名称 FAN BLADE COMPOSITE SEGMENTS
摘要 A fan blade includes a blade body, a composite segment and a cover. The blade body extends from a blade root to an opposed blade tip along a longitudinal axis. The blade body defines a leading edge and a trailing edge. A first airfoil surface extends from the leading edge to the trailing edge. A pocket is defined between the leading edge, the trailing edge, the blade root and the blade tip. The pocket has a bottom surface that opposes the first airfoil surface across the blade body. The composite segment is disposed in the pocket. The cover is mounted to the composite segment and to the blade body to form a second airfoil surface opposed to the first airfoil surface.

主权项 1. A fan blade, comprising: a blade body extending from a blade root to an opposed blade tip along a longitudinal axis, wherein the blade body defines a leading edge and a trailing edge, a first airfoil surface extending from the leading edge to the trailing edge, and a pocket defined between the leading edge, the trailing edge, the blade root and the blade tip, the pocket having a bottom surface that opposes the first airfoil surface across the blade body; a composite segment disposed in the pocket; and a cover mounted to the composite segment and to the blade body to form a second airfoil surface opposed to the first airfoil surface.
