  • Publication number: 20200307773
    Abstract: A tiltrotor controls shield having a blade or wire substructure under a fragile spinner fairing improves bird strike durability. The present disclosure discloses a spinner wind fairing with a shield structure disposed thereunder for providing protection to the proprotor assembly components. The shield structure can segment a projectile, such as a bird, that penetrates the spinner fairing into a series of smaller and lower energy elements spread across a wider area, such that the rotor components can withstand the impact of the smaller elements without damage.

  • Patent number: 10620237
    Abstract: A power supply is described having a current measurement circuit connected between a supply voltage terminal and an output voltage terminal of the power supply. The current measurement circuit comprises a set of two or more sense resistors in a parallel configuration, first and second ones of the sense resistors having different impedances. Switching circuitry is provided, which is responsive to a control signal to connect one or more of the sense resistors between the supply voltage terminal and the output voltage terminal. A controller is operable to generate the control signal in dependence on a measured current level across the set of sense resistors. In this way, by switching the resistors in and out of the circuit, the voltage drop across the measurement circuit can be kept to a desired range.

  • Publication number: 20190300151
    Abstract: A light weight hybrid torque transfer joint trunnion has an integral metal hub spline fitting oriented on a center axis. This integral metal hub spline fitting may be made of steel, aluminum, titanium, or the like and may be generally cylindrical. The integral metal hub spline fitting defines an integral central internally-splined mast or driveshaft coupling opening centered about the center axis. A composite material body centrally retains, and is cured to, the metal hub spline fitting. Torque transfer joint link attachment pins extend from the composite material body and are rigidly linked to the metal hub spline fitting. In an example constant-velocity joint, a plurality of pivoting linkages may each be rotatably coupled to the torque transfer joint link attachment pins, and each of the plurality of pivoting linkages may, in turn be secured to a rotor yoke configured to mount a plurality of rotorcraft blades.

  • Publication number: 20170256015
    Abstract: To improve pricing models for location based services, established geocoding/reverse geocoding services are used to enrich the locations defining the price item (start location, multiple end locations) and the pick-up/drop-off location with geocoding information like zip codes, coordinates and geographic boundaries. A multi-step matching algorithm then uses the geocoding values to determine 1) if there is a match between locations and 2) how good of a match there is. The match is measured by its “order.” For example, if the places are identical, they have a matching order 0, identical coordinates a matching order 1, matches based on zip codes have a matching order 2, matches based on geographic boundaries have a matching order 3, etc. Other sub-criteria, such as the number of zip codes or the size of an area, may also serve as tie-breaker. The order of the match may then be used to establish the correct predictive pricing model.
