Publication number: 20200140069Abstract: According to one embodiment, a clutch may be coupled between a rotor system and a power train of a rotorcraft. The clutch may be operable to disengage the rotor system from the power train during operation of the power train. A clutch control system in communication with the clutch and include a rotorcraft condition sensor operable to sense an operating condition of the rotorcraft and a control unit operable to prevent the clutch from disengaging the rotor system from the power train if the operating condition of the rotorcraft fails to satisfy a predetermined criterion.Type: ApplicationFiled: August 13, 2019Publication date: May 7, 2020Applicant: Bell Textron Inc.Inventors: Ryan T. Ehinger, David Sembritzky, Carlos A. Fenny, Gary A. Cope, Charles J. Kilmain

Patent number: 10145464Abstract: A lubrication system includes a reserve housing configured to retain a lubrication fluid. A supply line in fluid communication with the reserve housing is configured to provide pressurized lubrication fluid to the reserve housing. An overflow tube has an overflow port, the overflow tube being configured to prevent the volume of the lubrication fluid from exceeding a certain amount. A metering jet is configured to allow the lubrication fluid to flow from the reserve housing onto a component, such as a bearing, in the gearbox at a predetermined rate. The metering jet provides flow of the lubrication fluid onto the bearing even when the supply line no longer provides pressurized lubrication fluid to the reserve housing.Type: GrantFiled: October 4, 2016Date of Patent: December 4, 2018Assignee: Textron Innovations Inc.Inventors: Scott D. Poster, David A. Elliott, Gary A. Cope
