    Abstract: A cooled turbine blade having a base and an airfoil, the base including cooling air inlet and an internal cooling air passageway, and the airfoil including an internal heat exchange path beginning at the base and ending at a cooling air outlet at the trailing edge of the airfoil. The airfoil also includes a “skin” that encompasses a tip wall, an inner spar, a leading edge rib, and a leading edge air deflector. The leading edge rib is configured to form a leading edge chamber in conjunction with the leading edge of the skin. The leading edge air deflector is at least partially intersected by the inner spar.

    Abstract: An integrated compressor comprises an electric motor that is prone to windage losses, radial loads, and recirculation flows. According to a first feature, partial grooves or riblets may be formed on the surface of a motor stator that defines the radially outward boundary of the air gap between the motor stator and the motor rotor. These partial grooves or riblets may maintain low to moderate windage losses, while reducing radial loads in the motor. According to a second feature, a support structure may be designed with a nose portion that is configured to disrupt or otherwise reduce recirculation flows within the end-winding cavity housing the end-winding of the motor. According to a third feature, the spiral orientation of the top coil of the end-winding may be aligned with the rotation direction of the motor rotor to reduce recirculation flows within the end-winding cavity.

    Abstract: A pneumatically variable nozzle vane is disclosed that is capable of performing the same or similar function as a mechanically variable nozzle vane. Within its core, each pneumatically variable nozzle vane may comprise one or more cavities in fluid communication with one or more outlets to eject a gas from the nozzle vane into a flow path of working fluid through the nozzle. Each cavity may be shaped to match an internal pressure gradient to the external pressure gradient of the nozzle vane. The gas may be ejected as a curtain, substantially perpendicular to the flow path through the nozzle, to thereby manipulate the flow of a working fluid through the nozzle in a similar manner as a mechanically variable nozzle vane. In an embodiment, each nozzle vane may have two cavities supplying outlets on both the pressure-side and suction-side of the nozzle vane.

    Abstract: A system for coupling a first duct to a second duct configured for a gas flow with a gas turbine engine is disclosed. The system includes a first closed member and a second closed member. The first closed member is fixedly coupled to the first duct and defines an engagement surface. The second closed member is fixedly coupled to the second duct and defines a mating surface complementary to the engagement surface. The coupling of the first duct to the second duct includes one of the engagement surface and the mating surface complementarily receiving the other of the engagement surface and the mating surface such that a labyrinth interface is defined therebetween. Also, the first duct is sealed with respect to the second duct at the labyrinth interface such that a seepage of some of the gas flow through the labyrinth interface is restricted.

    Abstract: Large industrial machines, such as gas turbine engines, typically have a control room or control panel, acting as a single local control point from which the machine is operated. However, this prevents technicians from controlling the machine at locations that are distant from the control point, as may be necessary during servicing or operation. Accordingly, a system is disclosed that enables a wireless human-machine interface to be used to control the machine, in addition to a local human-machine interface. The system may ensure that only a single human-machine interface is able to control the machine at any given time, as well as prevent unauthorized devices from controlling the machine.
