Damped turbomachine blade |
摘要 |
<p>A fan blade (10) includes a metal airfoil (14) having first and second opposite sides (16,18) extending radially between a root (20) and a tip (22), and axially between a leading edge (24) and a trailing edge (26). The airfoil further includes a pocket (36) disposed in the first side having an elastomeric filler (40) bonded therein. A panel (42) is bonded to the filler along the pocket for allowing differential movement therebetween for damping vibratory response of the airfoil. <IMAGE></p> |
