VIBRATION DAMPING HINGE JOINTS FOR VARIABLE AREA JET ENGINE EXHAUST NOZZLES
摘要
13DV 9368 VARIATION DAMPING HINGE JOINTS FOR VARIABLE AREA JET ENGINE EXHAUST NOZZLES 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.
