  • Patent number: 6814098
    Abstract: A support structure for a C-ring includes a pair of circumferentially spaced holding members on catch plates. The holding members may be moved individually into the C-ring after the C-ring is mounted within an outer housing. The two holding members thus provide support to an inner periphery of the C-ring. A locking plate has support structure moved between circumferential ends of the housing members, thus providing effective support for the C-ring around its entire inner periphery. In this way, the two parts secured by the C-ring need not be moved relative to each other to insert the C-ring. The clearance or ability to move one of the two parts relative to the other which has been required in the past to mount a C-ring, is not necessary. This makes the inventive C-ring particularly useful for new applications, such as holding a porting sleeve within a valve housing.

  • Patent number: 6811376
    Abstract: A propeller control system provides for actuation through supply pressure only. A transfer bearing thereby requires only a single land. The supply pressure is metered at a pitch change valve within the rotating propeller shaft downstream of the transfer bearing to provide hydraulic pressure for actuation and control. A feather override mode is provided by energizing a feathering solenoid. The increased supply pressure changes the hydraulic force balance of the pitch change valve to allow the increased supply pressure into a Coarse Pitch chamber and simultaneously allow fluid within the Fine Pitch chamber to flow to drain pressure. The flow to drain changes the hydraulic balance on the Pitch Change Actuator Piston to drive a pitch link attached to each propeller blade and thereby change the pitch thereof towards coarse pitch.

  • Patent number: 6806589
    Abstract: A no break power transfer system that is particularly useful onboard an aircraft ensures that there is an appropriate frequency match between the outputs of different power supplies. A frequency adjuster between an auxiliary power unit and a load alters the frequency of power available from the auxiliary power unit before that power is supplied to the load. In one example, a controller determines when the frequency of output power from the main power supply does not match that from the auxiliary power unit. The controller controls the frequency adjuster to make an appropriate frequency change until there is a sufficient match. In one example, the frequency adjuster includes a rectifier that converts an alternating current output of the auxiliary power unit to a direct current output that is then converted by an inverter to provide an alternating current output having the appropriate frequency.

  • Patent number: 6789562
    Abstract: The subject invention is a valve for regulating the viscosity of fluid. The valve includes a housing defining a bore having a first inlet supplying “cold” hydraulic fluid at a first viscosity and a second inlet supplying “hot” hydraulic fluid at a second viscosity. A spool valve disposed within the bore has at least one land to proportionally control the flow of hydraulic fluid through the inlets. Hydraulic fluid from the first and second inlets mixes within the valve and exits the valve through an outlet at an optimum viscosity. A flow restrictor creates a pressure force on the spool valve that is proportional to the viscosity of the hydraulic fluid flowing through the outlet.

  • Patent number: 6776376
    Abstract: A flight control surface actuation system has a plurality of actuators attached to one or more summing levers. Each summing lever has an actuator output point that is attached to the flight control surface. The summing lever position corresponds with a sum of the positions of the actuators attached to it. If one of the actuators jams and becomes immovable, other actuators attached to the same summing lever as the malfunctioning actuator compensates for the malfunctioning actuator to bring the flight control surface to a neutral position. The summing lever makes it possible for flight control surface actuation systems to use actuators other than actuators having a bypass mode or any other features that prevent the actuators from jamming.

  • Patent number: 6769874
    Abstract: A permanent magnet alternator (PMA) includes a stator which rotates with a propeller shaft and a rotor which is mounted within the stator and rotates with a gas turbine engine output shaft. The rotor is driven at the relatively high speed of the turbine output shaft while the stator is driven at a relatively slow speed of the propeller shaft as reduced by an in-line gearbox. The great difference in speed between the propeller shaft and the turbine output shaft results in a compact PMA which provides significant electrical power output. As the stator of the PMA rotates with the propeller shaft, power is supplied directly to the rotating hub and blades without the heretofore necessary slip ring and associated electrical transmission components.
