  • Patent number: 9777632
    Abstract: Splitter apparatus for gas turbine engines are disclosed. An example splitter apparatus may include a splitter including an annular outer wall substantially defining a convex leading edge; an annular splitter support positioned radially within the outer and including a forward end disposed substantially against a splitter inner; and an annular first bulkhead spanning between the outer wall and the splitter support. The outer wall, the splitter support, and the first bulkhead may define a generally annular splitter plenum. The forward end of the splitter support may include spaced apart, radially oriented metering slots. The outer wall may include an inner portion disposed radially inward from the splitter inner surface extending aft and including spaced-apart exit slots. The splitter plenum, the metering slots, and the exit slots may conduct airflow from the plenum, through the metering slots against the splitter inner surface, and through the exit slots.

  • Patent number: 9777633
    Abstract: Systems and methods for adjusting airflow distortion in a gas turbine engine using a secondary airflow passage assembly are disclosed. A gas turbine engine can include a compressor section, a combustion section, and a turbine section in series flow and defining at least in part an engine airflow path. A casing can enclose the gas turbine engine and be at least partially exposed to a bypass airflow. The gas turbine engine can further include a secondary airflow passage assembly comprising a door and a duct, the duct defining an inlet located on the casing, the duct defining an outlet in airflow communication with the engine airflow path, the duct comprising an airflow passage extending between the inlet and outlet. The door can be moveable between an open and closed position to allow a portion of the bypass airflow to flow through the airflow passage to adjust airflow distortion.

  • Patent number: 9777637
    Abstract: The fuel flow rate to a gas turbine is measured using an inert gas. The inert gas is injected into the fuel flow and the concentration of the inert gas in the fuel/inert gas mixture is later measured. The concentration of the inert gas in the fuel/inert gas mixture is then used to calculate the mass flow rate of the fuel.

  • Patent number: 9777704
    Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine that controls pitch bearing load distribution. The assembly includes a rotor blade having a body shell extending between a blade root and tip, a pitch bearing at an interface between the blade root and a hub of the wind turbine, and plurality of blade bolts coupling the blade root to the hub through the pitch bearing. The pitch bearing includes an outer bearing race and an inner bearing race rotatable relative to the outer race. Thus, in one embodiment, the blade bolts couple the blade root to the hub through the inner race of the pitch bearing. Further, each of the blade bolts has a first end and a second end defining a length therebetween and at least two of the blade bolts have varying lengths so as to distribute loads experienced by the pitch bearing.
