A rotary damper (10) includes a stationary member (12) and a rotating member (14) provided within the stationary member (12) so that a gap (16) is defined between the rotating member (14) and the stationary member (12). The rotating member (14) further includes a central shaft (18) provided therein. A viscous fluid (19) is provided in the gap (16) and has an associated shear that provides a velocity damping within the gap (16). A differential growth in the gap (16) caused by temperature variation compensates for temperature damping variation. A compliant member (20) is provided within the stationary member (12) for providing thermal compensation. A secondary hermetic seal (26) is provided on the stationary member (12) for permitting limited rotation, defining a vacuum environment and preventing viscous fluid leakage to an external environment
