  • Patent number: 10773794
    Abstract: A dynamic rotor-phasing unit can phase rotors in-flight for dynamic rotor tuning and in an idle state for aircraft storage. The input and output shafts can be clocked (e.g., rotated) from 0 degrees apart to in excess of 360 degrees apart or from 0 degrees apart to 140 degrees apart. Such rotation can minimize the footprint of an aircraft for stowing purposes, as the rotor blades can be folded to fit within a smaller area without disconnecting the drive system. Additionally, the unit can allow tiltrotor blades to be clocked during flight, which can allow the live-tuning of the aircraft's rotor dynamics. A fail-safe rotary actuator can rotate a stationary planet carrier to clock the input shaft and the output shaft. Alternatively, an actuator can position a slider housing to clock the input shaft and the output shaft.

    Abstract: A starter for an engine is equipped with a planetary gear train as a torque variator to change torque used to start the engine. The torque variator is capable of changing the degree of torque which is transmitted between a planetary carrier and an outer gear of the planetary gear train, thereby changing a ratio of speed of a sun gear to speed of the planetary carrier of the planetary gear train to increase or decrease the degree of torque required to start the engine. This ensures the stability in starting the engine, for example, in cold conditions and achieves a quick start of the engine as needed.

Through a cam roller contact point between the pusher shaft and the cam raceway on the plunger; the rotational motion of the pusher shaft is converted to linear and translational motion of the plunger. The translational motion of the plunger allows impulse jet energy to be rapidly released from a nozzle of the pump.

  • Patent number: 9970509
    Abstract: An Epicyclic gearbox comprising one central gear, one or more offset gears and two carriers, requires one less gear than a planetary gearbox. It lacks an orbit gear and its planets maintain a fixed orientation as they circulate around the sun. The present invention provides a lower reduction ratio, reduced pitch velocity, higher torque capacity, and lower production cost than a planetary gearbox. An all-pinion design allows it to be fitted with gears, cables, chains, belts, or any other type of engaging means. Its high efficiency and low noise make it well suited to high speed operation and overdrive applications.
