  • Publication number: 20200308970
    Abstract: A compressor section includes a shroud surface and a rotor with a blade tip that opposes the shroud surface. The rotor is configured to rotate within the shroud about an axis of rotation. Moreover, the compressor section includes a serration groove that is recessed into the shroud surface. The serration groove includes a forward portion with a forward transition and a forward surface that faces in the downstream direction. The forward transition is convexly contoured between the shroud surface and the forward surface. The serration groove includes a trailing portion with a taper surface and a trailing transition. The taper surface tapers inward as the taper surface extends from the forward surface to the trailing transition. The trailing transition is convexly contoured between the taper surface and the shroud surface.

  • Publication number: 20200158128
    Abstract: A rotor for a compressor includes a hub and a plurality of airfoils having a root, a tip opposite the root and a span that extends from 0% at the root to 100% at the tip. Each of the airfoils is coupled to the hub at the root and is spaced apart from adjacent ones of the airfoils over the span by a throat dimension. The throat dimension has a maximum value at a spanwise location between 60% of the span and 90% of the span of the adjacent ones of the airfoils, and at 10% of the span of the adjacent ones of the airfoils above or below the spanwise location of the maximum value, the throat dimension is less than 97% of the maximum value. The throat dimension at 5% of the span of the adjacent ones of the airfoils is less than 70% of the maximum value.

  • Patent number: 10524366
    Abstract: A polymer film is applied onto a surface of a laminated printed circuit board subassembly having vias. Holes are created in the polymer film to access the vias while the polymer film remains covering adjacent areas. The polymer film with holes allows placement of hole-fill paste in the vias while preventing unwanted hole-fill paste placement or migration to adjacent areas. After filling the vias with hole-fill paste, the hole-fill paste is preferably at least partially hardened or cured, and the polymer film is preferably removed, facilitating further assembly of a printed circuit board without unwanted hole-fill paste in other areas which could be difficult to remove, The invention includes improved processes for fabricating printed circuit boards, and is particularly useful for irregular circuit boards and rigid flex circuit boards. The invention also includes covered laminated printed circuit board subassemblies, covered with a removable polymer film.

  • Publication number: 20190360297
    Abstract: A radially expandable backup ring (50) with relatively rigid segments (56) and relatively resilient segments (58) that are integral with one another to circumferentially urge the relatively rigid segments (56) together when the backup ring (50) expands. The backup ring (50) may radially expand to reduce or eliminate a radial gap between the backup ring (50) and a radially inwardly facing surface of a corresponding cased wellbore (22) to prevent or minimize axial extrusion of a corresponding sealing member (32), such as a compressible packer seal of a cased-hole retrievable packer assembly. The relatively resilient segments (58) allow the backup ring (50) to elastically expand and retract to prevent axial extrusion of the sealing member (32). The relatively rigid support segments (54) may be axially aligned with a corresponding relatively resilient segment (58) of the backup ring to prevent axial extrusion of the sealing member (32) through the corresponding relatively resilient segment (58).

  • Publication number: 20190331247
    Abstract: A method and system are provided for supplying back-up electric power to an electric actuator powered by a supply of main electric power, and to interrupt or to replace a control signal supplied to the actuator so that the actuator can be reverted to a fail-safe mode, condition or position when there is a failure or disruption of the main electric power or when the control signal is not within the accepted pre-determined standard or range for the control signal.

  • Patent number: 10384803
    Abstract: Lighting components for illuminating an aisle portion of a cabin floor of an aircraft, and aircraft and passenger seats for an aircraft including the same are disclosed. Said lighting components are configured to illuminate at least a portion of the aisle, between adjacent passenger seats positioned on either side of the aisle. The lighting components are configured to direct light towards the cabin floor using a specially designed housing and reflector surface that are designed to illuminate objects in the aisle, while minimizing light pollution in the cabin and detection by passengers on board the aircraft. Said lighting components are optionally mounted on one or more passenger seats, and/or may be integrally formed with a passenger seat. Lighting components include a curved reflector surface configured to reflect light from a light source positioned within the housing such that it is directed towards the aisle to create the desired illumination.
