    摘要: A Health and Usage Monitoring System (HUMS) utilizes a common architecture which permits OEM and rotorcraft operators to view and trend HUMS data for an entire aircraft fleet independent of aircraft model, HUMS vendor, or raw data format. The system operates through a web portal that provides users with comparative information on HUMS parameters relative to fleet statistics. The user may view HUMS data for the entire fleet or drill down to a particular HUMS acquisition on a specific flight. The web based format also facilities display and communication of warnings in a timely manner.

    摘要: A drive train assembly for a rotor assembly having ducted, coaxial counter-rotating rotors includes a sprag clutch, an engine coupling subassembly, a transmission coupling subassembly, and a drive shaft mechanically interconnected at the ends thereof to the engine and transmission coupling subassemblies, respectively. The drive train assembly is design optimized to maximize the functional capability of the sprag clutch, the engine coupling subassembly including an external crown spline coupling, internal spline coupling combination that is mounted in combination with the sprag clutch so that loads transmitted through the external crown spline coupling react through the center of the sprag clutch. Further, the drive train assembly is design optimized to maximize allowable axial, angular, and/or parallel misalignments between the engine and the rotor assembly as a result of the mechanical interconnection of the drive shaft to the external crown spline coupling, internal spline coupling combination of the engine coupling subassembly and to the external crown spline coupling, gear spline coupling combination of the transmission coupling subassembly. The drive shaft is configured as a torque tube having inside and outside diameters sized to provide torsionally soft drive shaft such that the drive shaft functions as a torsional spring to isolate spline coupling teeth, the sprag clutch, transmission gearing, and the rotor assembly from vibratory torque generated by the engine.

    摘要: A progressive clutch includes a centrifugal clutch 10 attached to a drive shaft and inserted into a clutch housing assembly 16 to engage with clutch material 28 during low rpm operation. As the rpm of the input drive shaft 2 increases, the centrifugal force on pellets 32 overcomes the force of compression springs 34, and extension springs 40 pull a pin engagement assembly 30 towards the clutch housing assembly 16 thus engaging pins 38 into elongated holes 42 to provide positive drive from the drive shaft 2 to the driven shaft 21.

    摘要: A method for reducing a nose-up pitching moment in an unmanned aerial vehicle during forward flight. The unmanned aerial vehicle includes counter-rotating rotor assemblies that are mounted within a duct. Each rotor assembly includes a plurality of rotor blades. The method involves adjusting the rotor blades to have substantially zero pitch. Then rotating the rotor assemblies to produce a virtual plane across the duct. The virtual plane is operative for substantially deflecting air passing over the fuselage away from the duct. In one embodiment of the invention, the method involves the further step of obstructing at least a portion of the bottom of the duct to inhibit air that is flowing across the bottom of the duct from passing into the duct.

    摘要: An unmanned aerial vehicle that includes a fuselage with a partial toroidal forward portion, and an aft portion. A duct is formed through the fuselage and extends from the top to the bottom of the fuselage. Two counter-rotating rotor assemblies are mounted within the duct for providing downward thrust through the duct. The rotor assemblies are supported by a plurality of support struts. At least one engine is mounted within the fuselage and engages with the rotor assemblies. A pusher prop assembly is mounted to the aft portion of the fuselage. The pusher prop assembly is designed to provide forward thrust along the longitudinal axis of the aircraft. The pusher prop assembly includes a drive shaft that is engaged with the engine. A plurality of propellers are attached to and rotated by the drive shaft. A shroud is mounted to the aft portion of the fuselage around the propellers and is operative for channeling the air passing through the propellers in a substantially aft direction. A pair of wings is removably attached to the sides of the fuselage. Each wing preferably includes a fixed portion and a pivotal flaperon portion hinged to the fixed portion. Directional vanes are preferably mounted to the shroud downstream from the propellers and control flow out of the shroud. Deflectors may be mounted to the bottom of the fuselage across a portion of the duct to control flow of air into the duct.
