  • Friction damper for gas turbine engine blades
    Patent number: 5599165
    Abstract: A friction damper (50) provides friction damping for gas turbine engine airfoils to reduce vibrations thereto. The friction damper (50) includes a plate (52) underlying radially outer shrouds (30) of two adjacent airfoils (20). Friction generated between an outer surface (53) of the plate (52) and undersides (42) of the adjacent shrouds (30) reduces undesirable vibrations in the airfoils (20).
    Type: Grant
    Filed: January 31, 1996
    Date of Patent: February 4, 1997
    Assignee: United Technologies Corporation
