Abstract
A yoke assembly for an aviation flight simulator capable of generating the appropriate control signals and mechanical responses for realistic flight simulation, including trim adjustment. In a preferred embodiment, the assembly comprises a rotatable and axially movable yoke shaft extending in an axial direction; a pair of sliding blocks mounted to be movable in the axial direction; a first spring rotationally coupling the yoke shaft with a first sliding block for simulating the rotational restoration force on an aircraft yoke; a second spring axially coupling the yoke shaft to the second sliding block for simulating the axial restoration force on an aircraft yoke; and adjustment means for adjusting the axial position of the second sliding block for simulating the effect of trim adjustment of an aircraft.
