Lift fan clutch plate to reduce instability

A clutch for a lift fan comprises at least one output shaft lug key positioned in a keyway of at least two output clutch plates and extending axially from one to the other of the two output clutch plates. The output shaft lug key couples the rotation of the output clutch plates to the rotation an ou...

Beschreibung
Zusammenfassung:	A clutch for a lift fan comprises at least one output shaft lug key positioned in a keyway of at least two output clutch plates and extending axially from one to the other of the two output clutch plates. The output shaft lug key couples the rotation of the output clutch plates to the rotation an output shaft and allows axial movement of the two output clutch plates relative the output shaft lug key. The width of an inner surface of the output shaft lug key varies along the axial length as a function of the proximity to a home axial position of each of the output clutch plates when in the disengaged position.
