Patent ID: 8226039

Claim:
A method for operating an unmanned aircraft, the method comprising: coupling a first fuselage section of the aircraft to a second fuselage section of the aircraft with a vibration isolation device; flying the aircraft; and inhibiting vibration transfer from the second fuselage section to the first fuselage section during flight operations with the vibration isolation device by— inhibiting translational movement of the first and second fuselage sections relative to each other along a longitudinal axis with a first translational force, and inhibiting translational movement of the first and second fuselage sections relative to each other along a lateral and vertical axes with a second translational force and a third translational force, respectively, and wherein the second and third translational forces are less than the first translational force; and inhibiting rotational movement of the first and second fuselage sections relative to each other about a pitch axis and a yaw axis with a first rotational force and a second rotational force, respectively, and inhibiting rotational movement of the first and second fuselage sections relative to each other about a roll axis with a third rotational force less than the first and second rotational forces.
