摘要： A multi-plate clutch is provided to couple a drive shaft from a gas turbine engine with a driven shaft of a lift fan. When disengaged the plates of the clutch can be physically separated. Plates of one shaft are coupled to the shaft with individual energy members that return the plates to a disengaged position. The plates of the other shaft can be coupled together with a travel member and/or lug key and energy devices between at least some of the plates.

摘要： A rotor aircraft has an engine, a propeller, wings, and a rotor. An electric motor is coupled to the rotor drive shaft for applying torque to the rotor drive shaft. The electric motor is sized to supply all of the torque to pre-rotate the rotor to a selected speed prior to liftoff of the aircraft. The wings are capable of providing substantially all of the lift required during forward flight at a cruise speed. The rotor being is capable of being trimmed to provide substantially zero lift and auto-rotate at cruise speed. Sensors sense flight conditions of the aircraft and provide signals to a controller that selectively causes the electric motor to cease applying torque to the rotor drive shaft during autorotation at cruise speed. The controller also causes the electric motor to apply torque to the rotor drive shaft if the sensors indicate additional rotor speed is needed.

摘要： A transmission system that is used in conjunction with a microturbine engine for propelling an aircraft body, such as a propeller-based fixed-wing aircraft or a rotor-based vertical lift aircraft, or for a wide variety of other applications. The output shaft of the microturbine engine preferably operates at a rotational speed in a range between 72,000 RPM and 150,000 RPM with an output power between 150 HP and 5 HP (and most preferably operates in an extended range between 50,000 RPM and 200,000 RPM with an output power between 200 HP and 5 HP). The two reduction stages provide a reduction ratio preferably having a value of at least 19, and most preferably greater than 24. The transmission system is of small-size preferably having a maximum diameter less than twelve inches. The two stages of the transmission system may comprise any one (or parts of) of a number of configurations, including an in-line lay shaft configuration, an in-line star-star configuration, an offset star-spur configuration, an offset compound idler configuration, an inline traction-internal gear configuration, and an inline traction-planetary gear configuration. Preferably, the input stage of the transmission system is self-equilibrating such that first shaft can be supported without bearings and is operably coupled to the output shaft of the microturbine engine by an outside diameter piloted spline coupling mechanism. For vertical lift applications, a single traction stage along with a bevel gear assembly or other shaft transmission mechanism can be used to provide the necessary RPM reduction.

摘要： A composite drive shaft in which the end adapters are captured in the composite material portion during the process of manufacturing of the composite drive shaft assembly is disclosed. The end adapters include lugs that protrude outward longitudinally to transmit torque, tensile, and compressive forces, and bending moments to the composite material portion and vice versa. To increase the load carrying capacity for axial force and bending moment, the end adapters may have at least one recessed circumferential groove. Before the manufacturing process, one or more bonding agents may be applied onto the interface of the end adapter to enhance the performance of engagement between the end adapters and the composite material portion. The composite material portion and end adapters are co-cured to produce a final drive shaft that requires no additional work for assembly.
