Composite fan blade trailing edge reinforcement |
摘要 |
The present invention provides a composite airfoil, particularly useful as a wide chord fan blade having a high degree of twist in a large high bypass ratio turbofan engine. The composite airfoil of the present invention has a reinforced region of its airfoil that extends a portion of its span from its tip and a portion of its chord from its trailing edge. The region is covered by thin metallic sheathing bonded to trailing edge surfaces of the blade in a manner to reinforce that portion of the composite blade. |
