<p>PROBLEM TO BE SOLVED: To provide a hybrid fan blade improved in damping performance while holding durability to foreign matter damage. SOLUTION: A fan blade 10 includes a metal blade profile part 14 having a first and a second side surface 16, 18 extended in a radial direction between a root 29 and a tip end 22 and extended in an axial direction between leading and trailing edges 24, 26 to be opposed to each other. This blade profile part 14 further includes a pocket 36 provided in the first side surface and a pocket 36 connecting an elastomer filler material 40 to the inside thereof. A panel 42, since a differential motion between the pocket 36 and the panel can be performed to damp a vibration response in the blade profile part 14, is connected to the filler material 40 along the pocket 36.</p> |
