Patent
Hamilton Sundstrand | Date: 2016-01-12

A method includes receiving torque data of a powder recoater operatively connected to an additive manufacturing system. The torque data includes torque data of the recoater when the recoater traverses a build area. Receiving torque data includes receiving force data from a plurality of load cells, each load cell operatively associated with a blade segment of a recoater blade assembly. The method also includes determining a quality of one or more of an additive manufacturing process and/or product based on the torque data.

An aircraft control system includes a propeller shaft assembly. Also included is first rotor operatively coupled to the propeller shaft assembly, the first rotor having a first plurality of blades mounted thereto, the first blades disposed at a substantially identical nominal pitch during rotation of the first rotor, the first rotor rotatable in a first direction. Further included is a second rotor operatively coupled to the propeller shaft assembly and rotatable in a second direction, the second rotor having a second plurality of blades mounted thereto, wherein a pitch of the second blades cyclically changes during rotation of the second rotor, the first rotor and the second rotor disposed and rotated proximate a fixed wing of an aircraft about a common axis extending parallel to a longitudinal axis of the aircraft, cyclically changing the pitch of the second plurality of blades generating a moment for controlling the aircraft.

A method 100 includes receiving 101 torque data of a powder recoater (201) operatively connected to an additive manufacturing system (200). The torque data includes torque data of the recoater (201) when the recoater traverses a build area (205). The method also includes determining 103 a quality of one or more of an additive manufacturing process and/or product based on the torque data.


Patent
Hamilton Sundstrand | Date: 2017-05-17

A method 100 includes receiving 101 an image from an optical imaging device (207) disposed in operative communication with an additive manufacturing machine (200), wherein the image includes at least part of a build area (205) of the additive manufacturing machine, determining (103) a reflectance of at least a portion of the build area based on the image to create reflectance data, and determining (105) a quality of one or more of an additive manufacturing process and/or product based on the reflectance data. The method can further include converting the image to greyscale if the image is not in greyscale.


Patent

A power distribution system includes an electrical contactor arrangement. The electrical contactor arrangement includes a first contactor post, a first contactor lead, and a second contactor lead. The first contactor post extends from a first bus bar. The first contactor lead extends from the first contactor post. The first contactor lead is at least partially received within a contactor housing. The second contactor lead is spaced apart from the first contactor lead and extends from the first contactor post. The second contactor lead is at least partially received within the contactor housing.


Patent

An embodiment of a gear pump arrangement includes a first gear (48) defining a first set of teeth; and a second gear (50) defining a second set of teeth, the first set of teeth and the second set of teeth being in meshed communication such that fluid is pumped in response to rotation of the first gear and the second gear, at least one of the first set of teeth and the second set of teeth having at least one gear tooth passageway through each tooth thereby fluidically connecting opposing faces of the tooth.


Patent
Hamilton Sundstrand | Date: 2017-09-20

A gearbox mounting link between a gas turbine engine structure and a gearbox mounting location comprises an engine attachment piece (104) rotatably secured to the gas turbine engine structure. The engine attachment piece comprises first and second plates (114, 116) extending in parallel planes and separated by a gap. A gearbox attachment piece (106) is situated between the parallel plates and secured to the gearbox (12). A breakable primary retention fastener (110) extends snugly through the parallel plates and the gearbox attachment piece, thereby rigidly retaining the gearbox with respect to the gas turbine engine in two degrees of freedom so long as the breakable primary retention fastener remains intact. A durable secondary retention fastener (112) extending snugly through the parallel plates, and extends with clearance through the gearbox attachment piece via an oversized fastener passage, thereby constraining the gearbox attachment piece if the breakable primary retention fastener breaks.
