1. An unmanned aircraft system, comprising:
- a fuselage having a first fuselage section and a second fuselage section adjacent to and at least approximately longitudinally aligned with the first fuselage section; and
at least one vibration isolation device coupling the first fuselage section to the second fuselage section, wherein the vibration isolation device is—
translationally stiffer along a longitudinal axis than it is along a lateral axis and a vertical axis; and
rotationally stiffer about a pitch axis and a yaw axis than it is about a roll axis.

Abstract
Vibration isolation devices and associated systems and methods are disclosed herein. In one embodiment, for example, an unmanned aircraft can include a fuselage having a first fuselage section and a second fuselage section adjacent to and at least approximately longitudinally aligned with the first fuselage section. The aircraft can also include at least one vibration isolation device coupling the first fuselage section to the second fuselage section. The vibration isolation device is translationally stiffer along a longitudinal axis than it is along a lateral and a vertical axis, and rotationally stiffer about a pitch and a yaw axis than it is about a roll axis.

12. An aircraft system, comprising:
-
an unmanned aircraft having a fuselage and a pair of wings extending from the fuselage; a first component carried by the aircraft; a second component carried by the aircraft and positioned adjacent to the first component; and a vibration isolation assembly coupling the first component to the second component, wherein the vibration isolation assembly is configured to (a) resist relative movement between the first and second components with respect to one translational degree of freedom and two rotational degrees of freedom, and (b) allow relative movement between the first and second components with respect to two translational degrees of freedom and one rotational degree of freedom. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An aircraft system, comprising:
-
an unmanned aircraft including a fuselage having (a) a first fuselage section including a nose portion with a turret assembly and a surveillance payload carried by a gimbal system, and (b) a second fuselage section immediately aft of and at least approximately longitudinally aligned with the first fuselage section; and a plurality of vibration isolation devices arranged generally symmetrically about an outer circumference of the fuselage and positioned to couple the first fuselage section to the second fuselage section, wherein each vibration isolation device is— translationally stiffer along a longitudinal axis than it is along a lateral axis and a vertical axes; and rotationally stiffer about a pitch axis and a yaw axis than it is about a roll axis; and wherein the individual vibration isolation devices include— a tensioning member connected to and extending between a first member attached to the first fuselage section and a second member attached to the second fuselage section, wherein the tensioning member includes a first wire and a second wire, wherein the first member including a first base having a non-linear first mating surface, a first channel, and a first clamping plate engaged with a first end portion of each of the first and second wires, and wherein the non-linear first mating surface faces the second member, and wherein the second member includes a second base having a non-linear second mating surface configured to mate with the first mating surface, a second channel positioned to receive another portion of the tensioning member, and a second clamping plate engaged with a second end portion of each of the first and second wires, and wherein the first and second mating surfaces define, at least in part, one interlocking finger. - View Dependent Claims (23, 24)
