  • Patent number: 8786117
    Abstract: A sensor assembly for use with a wind turbine rotor blade is provided. The sensor assembly includes an air data probe including a base shaft, a tip, and a rod portion extending therebetween, wherein the rod portion is fabricated from a composite material. The sensor assembly includes a receptacle configured to couple within the leading edge of the rotor blade for receiving the base shaft therein such that the tip extends a distance from the leading edge when the base shaft is received within the receptacle.
    Type: Grant

  • Patent number: 8430628
    Abstract: A pressure balance seal includes a sealing surface facing an inward radial direction, and a stator interface comprising at least one surface interfacing with a stator. The pressure balance seal further includes a friction reducing feature. The friction reducing feature includes a cavity on the sealing surface. The cavity is configured to receive a fluid such that a normal force acting on the pressure balance seal is counterbalanced by a force generated by a pressure of the fluid.

  • Publication number: 20120087808
    Abstract: The present disclosure is directed to liquid ring compressors that can be employed to remove liquid from a wet gas and/or to compress a wet gas. In one embodiment, a liquid ring compressor includes a shaft, a main body inner casing disposed about the shaft to form a chamber between the shaft and the main body inner casing, and an inlet configured to remove a portion of liquid from a wet gas and to direct the wet gas into the chamber. The liquid ring compressor also includes an impeller rotatably disposed within the chamber and configured to direct a remaining portion of the liquid in the wet gas out towards the main body inner casing to form a liquid ring within the chamber to compress the wet gas.

  • Patent number: 8135245
    Abstract: A fiber optic sensing system comprises a housing disposed in a flow path, and a fiber optic sensor. The fiber optic sensor comprises an optical fiber secured in the housing, a Bragg grating, a light source for transmitting light to the optical fiber, and a detector for detecting light filtered by the Bragg grating of the optical fiber and monitoring wavelength changes of the detected light. The fiber is substantially perpendicular to the flow path. The housing defines an opening at an upstream side to allow flow through the flow path to exert a pressure on the optical fiber and cause a deformation of the Bragg grating.
