Title:
UNMANNED AIRCRAFT VIBRATION-DAMPING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2017/179160
Kind Code:
A1
Abstract:
Provided is an unmanned aircraft vibration-damping structure having a simple, lightweight, and small configuration which can be manufactured at low cost, and which is capable of effective vibration damping of an object to be vibration-damped, even if complicated vibration specific to unmanned aircrafts occurs. An unmanned aircraft vibration-damping structure 1 for vibration damping of an object to be vibration-damped mounted on an unmanned aircraft is equipped with two or more viscous-fluid-filled dampers 2 each comprising: a support shaft 22 supporting the object to be vibration-damped; an elastic body 23 provided around the support shaft 22; and viscous fluid 235 filled in the elastic body 23. The object 5 to be vibration-damped is fixed to the unmanned aircraft in such a manner that the object 5 to be vibration-damped is horizontally sandwiched by the viscous-fluid-filled dampers 2 fixed to the unmanned aircraft 7 when the unmanned aircraft 7 is in a horizontal orientation.
