ABSTRACT:
An aircraft control mechanism for a speed brake includes a shaft, an outer sleeve surrounding the shaft and a sprag clutch. The mechanism also includes input and output elements and a control element with the input element tied to the outer sleeve. The control element is tied to the shaft and the output is operatively connected to the output of the clutch. A control cable is connected to the output for moving a speed brake between a first and a second position. A manual input actuates the control element of the clutch. An automatic input is connected to the outer sleeve through a torsional dampening device which minimizes chatter or sticking due to high forces which are required to extricate the sprag clutch from a relatively high racked-in load.
