Vibration Damping Hinge Joints For Variable Area Jet Engine Exhaust Nozzles

US Patent:
5101533, Apr 7, 1992
Filed:
Oct 11, 1989
Appl. No.:
7/419918
Inventors:
Richard E. Stenger - Cincinnati OH
William C. Lippmeier - Cincinnati OH
Joseph S. Alford - Cincinnati OH
David O. Fitts - Ballston Spa NY

Abstract:
A spring biased bearing is slidably mounted within a clevis joint so as to apply a frictional damping force to a flap of a jet engine exhaust nozzle. A forward hinge joint restrains the bearing against rotation with the flap while an aft hinge joint provides for both rotation and translation of the bearing about the flap. A tubular canister may be used with the hinge joint to preset the axial compression and biasing force generated by a coil spring enclosed within the canister.
