  • Publication number: 20200018190
    Abstract: A turbine blade includes an airfoil that has a tip region that extends from the leading edge toward the trailing edge, and the tip region is bounded by a wall that extends at a positive angle. The leading edge has a leading edge cooling circuit that is defined from the platform to a tip flag channel, and the leading edge cooling circuit is in fluid communication with the tip flag channel. The pressure side includes at least one tip dust hole defined through the wall proximate the pressure side, and the at least one tip dust hole has an inlet and an outlet. The airfoil has at least one rib defined on the wall that extends at a second angle, and the at least one rib merges with at least one flow scoop to direct the particles and a portion of the cooling fluid into the inlet.

  • Publication number: 20180297267
    Abstract: A system for manufacturing a cylindrical, nanoimprint lithography master includes, in one embodiment, a flat master coated with a first layer of compliant photopolymer material, a cylindrical master with an outer sleeve formed from a second layer of compliant photopolymer material, and a light source. The cylindrical master is disposed in tangential contact against the flat master such that the first and second layers of compliant material exhibit 5%-20% compressive strain within the region of contact. Through such pressure, the feature pattern in the flat master is imprinted into the first layer of material. Light from the light source is acutely focused into a narrow curing zone within the contact region. Curing causes the first layer of photopolymer material to bond to the outer sleeve. Through geometric matching and synchronized movement between the flat and cylindrical masters, the cylindrical master can be patterned about its periphery without creating a seam.

  • Patent number: 9410702
    Abstract: Disclosed in various exemplary embodiments are turbine engine combustors with effusion and impingement cooling and methods for manufacturing the same. In one exemplary embodiment, disclosed is a combustor for a turbine engine that includes an annular liner portion including a first metering hole positioned on a cold side annular surface of the annular liner portion and an impingement chamber positioned in the annular liner. The impingement chamber connects to an entry hole on the cold side annular surface and includes a cooling air outlet passageway that is angled with respect to a hot side annular surface of the annular liner portion and that connects to an exit hole positioned on the hot side annular surface of the annular liner portion. The first metering hole is connected to the impingement chamber. The cooling air outlet passageway directs the air onto the hot side annular surface and spreads the airflow axially and laterally parallel to the hot side annular surface.

  • Patent number: 8720745
    Abstract: A product dispensing system includes a partially-open container for retaining a supply of the product, a mechanism for dispensing a quantity of the product from the container, and a remotely-activated security device for selectively restricting the dispensing of product from the container. In one embodiment, the security device is in the form of a spherical enclosure that is mounted over the inlet port for a draw tube of the dispensing mechanism. In use, the security device includes an activation mixture, such as an expandable adhesive, that transitions the security device between a first state and a second state in response to an application of certain non-mechanical stimuli, such electromagnetic energy of a particular profile, the security device restricting the passage of the product through the draw tube when disposed in the first state and permitting the passage of the product through the draw tube when disposed in the second state.
