  • Publication number: 20100158700
    Abstract: A turbine blade assembly includes an airfoil, a platform, and a first cover plate. A center flow path extends through the platform in communication with an internal cooling circuit of the airfoil, which extends from a first side of the platform. A second side of the platform is located opposite the platform from the first side. An edge of the platform extends between the first and second sides and, a first passage is formed between the first and second sides and includes a first inlet and a first outlet. The first passage extends from the center flow path toward the platform edge, and a first groove is formed on the second side of the platform and extends from the first outlet of the first passage toward the edge of the platform. The first cover plate is disposed over the second side of the platform covering the first groove.

  • Publication number: 20090148305
    Abstract: A turbine blade includes a convex suction side wall, a concave pressure side wall, a tip wall, an internal cooling circuit, and a plurality of tip edge channels. The tip wall is recessed from a first tip edge of the suction side wall and a second tip edge of the concave pressure side wall to define a suction side wall tip section and a pressure side wall tip section, and the suction side wall tip section is shorter than the pressure side wall tip section. The internal cooling circuit is formed at least partially between the convex suction side wall, the concave pressure side wall, and the tip wall. The plurality of tip edge channels formed through the first tip edge of the convex suction side wall extend to the internal cooling circuit. Methods of manufacturing turbine blades are also provided.

  • Patent number: 7433398
    Abstract: The invention provides a DMT or OFDM equalization system that deals with each tone not only separately, but also globally, which provides better overall performance. In the inventive system, only M+T variables are required to be determined, where M is the number of tones and T represents the number of SIRF taps. The invention defines a matrix R, in which optimal coefficients are found as the eigenvector corresponding to the smallest eigenvalue of the matrix R. The dynamic range of all variables is limited in a system in accordance with the present invention, which provides ease of hardware implementation. Furthermore, the inventive system retains the advantages of per-tone equalization by providing a smoother signal-to-noise ratio (SNR) distribution function versus synchronization delay. In addition, no effort is wasted on the equalization of unused tones, because it is unnecessary to determine the coefficients for unused tones.

  • Patent number: 7309663
    Abstract: The present invention provides an asymmetric porous PTFE membrane for clothing having little change over time and conventionally known properties of a porous PTFE molded article such as water permeability resistance, air permeability, sealing properties and electric properties, in which durability and water vapor permeability are improved by strengthening adhesion strength with fabric. Specifically, the present invention relates to an asymmetric porous PTFE membrane for clothing comprising a dense skin layer and a continuously foamed porous layer, wherein (1) the contact angle of water to the surface of the skin layer is 120 to 140°; and (2) the diffuse reflectance of light of the skin layer is 91 to 94%.
