Abstract: A clutch system configured to transmit torque between an input shaft and an output shaft. The clutch system may include a clutch and a lubrication supply system. The clutch may include: an input portion disposed at an end of the input shaft; an output portion disposed at an end of the output shaft; and a sliding component that slides axially between the input and output portions to engage the clutch. The lubrication supply system may include: one or more lubricant feeds for delivering a lubricant to the clutch; and one or more lubricant drains for draining the lubricant from the clutch. The one or more lubricant feeds may include one or more respective valves. The one or more valves each may be configurable between settings that vary an amount of the lubricant delivered to the clutch via the respective one of the one or more lubricant feeds.

Abstract: Various embodiments include apparatuses and systems for controlling rotational imbalance of a rotary element. In one embodiment, a rotational imbalance reduction apparatus includes at least one heating element for heating a location on a rotary element, a pulsing element configured to pulse actuate the heating element in synchronization with a multiple, fraction, or mixed fraction of the frequency of rotation of the rotary element, and a control system coupled with the pulsing element and the heating element, the control system actuating the heating element and the pulsing element to apply heat to the location of the rotary element in pulses synchronized with the multiple, fraction, or mixed fraction of the frequency of rotation of the rotary element.
