Abstract
A clutch for a lift fan with input and output shafts on a common rotational axis, connected by disc shaped output clutch plates oriented normal to the axis. A keyway extends radially inward from a mouth at an outer diameter of each output clutch plate to a seat at an inner diameter of the respective clutch plate. At least one output shaft lug key may be positioned in the keyway and extends axially from one output clutch plate to the other output clutch plate, which couples the rotation of the output clutch plates to the rotation the output shaft and allows axial movement of the two output clutch plates relative the output shaft lug key, the output shaft has an outer radial surface and an inner radial surface. At least one input clutch plate positioned axially between the two output clutch plates and rotationally fixed to the input shaft.
