Abstract
An exemplary tiltrotor aircraft includes a fuselage carrying a wing, a pylon assembly coupled to the wing such that the pylon assembly is rotatable to selectively operate the tiltrotor aircraft between a helicopter mode and an airplane mode, a vibration isolator assembly connected to the pylon assembly and the wing including a first vibration isolator configured to isolate vibration in a vertical plane a second vibration isolator configured to isolate vibration in a lateral plane.
Claims18
A vibration isolator assembly for connecting a first body and a second body, the vibration isolator assembly comprising:
- a first liquid inertial vibration isolator configured to isolate vibration in a first plane, the first vibration isolator comprising a first cylinder extending between first outer housings;
- a second liquid inertial vibration isolator configured to isolate vibration in a second plane, the second vibration isolator comprising a second cylinder extending between second outer housings;
- and
- a spherical bearing connected to the first and the second cylinders at an intersection of the first and the second cylinders.
A tiltrotor aircraft comprising:
- a fuselage carrying a wing;
- a pylon assembly coupled to the wing such that the pylon assembly is rotatable to selectively operate the tiltrotor aircraft between a helicopter mode and an airplane mode;
- a liquid inertial vibration isolator assembly having a spherical bearing connected to the pylon assembly and outer housings mounted to the wing, the vibration isolator assembly comprising:
- a first vibration isolator configured to isolate vibration in a vertical plane, the first vibration isolator having a first cylinder extending along the vertical plane between first outer housings of the outer housings;
- a second vibration isolator configured to isolate vibration in a lateral plane, the second vibration isolator having a second cylinder extending along the lateral plane between second outer housings of the outer housings;
- and
- the spherical bearing connected to the first cylinder and the second cylinder at an intersection of the first cylinder and the second cylinder.
