Abstract
A rotatable damper (100) comprises a mass (110) fully rotatable around an axis of rotation configured for self-damping a mechanical disturbance. The rotatable mass comprises a fully rotatable structure comprising an outer frame (2100) and an inner frame (2400) bound to rotate with the fully rotatable structure and further movable one relative to the other in at least one axis and a first chamber (3200), disposed between the outer frame and the inner frame, containing a fluid and comprising a first opening in direct communication with a first constriction (3300). The first chamber is readily compressible between a first portion of the outer frame and a second portion of the inner frame when forcibly approached by said mechanical disturbance. The first chamber, when compressed, is configured to expel at least partially the fluid through the first constriction, thereby facilitating damping of the mechanical disturbance.
