20160047355 | METHODS OF MANUFACTURING AN IMPREGNATED METAL INSERT - Method of manufacturing an impregnated metal insert for a wind turbine blade root, the insert comprising an outer surface and an open end adapted to receive a fastening element for attachment to a wind turbine rotor hub, wherein the method comprises covering the insert outer surface with one or more resin pre impregnated fibre layers, and heating for curing such that a resin impregnated fibre layer adheres to the outer surface of the insert. The disclosure is further related to the method of manufacturing a portion of a wind turbine blade. | 02-18-2016 |
20160053619 | CMC BLADE WITH INTEGRAL 3D WOVEN PLATFORM - A method of forming a component for use in a gas turbine engine includes the steps of forming an airfoil/root assembly; creating a platform assembly structure having an opening; inserting the airfoil/root assembly into the opening; and bonding the platform assembly structure to the airfoil/root assembly to form the component. | 02-25-2016 |
20160076374 | LASER NET SHAPE MANUFACTURED COMPONENT USING AN ADAPTIVE TOOLPATH DEPOSITION METHOD - A laser net shape manufactured BLISK, compressor blade, turbine blade or turbine component including a plurality of overlapping predetermined variable bead widths of a material defining a first material layer, a plurality of overlapping predetermined variable bead widths of a material deposited on top of the first material layer, forming a second material layer; and additional material layers deposited on top of the first material layer and the second material layer. The variable bead width of the deposited material is controlled to maintain the approximately constant percent of bead width overlap. A first 2 to 100 deposited powder layers are deposited by a first laser power and the remaining powder layers are deposited by a laser power that is ramped down over the course of depositing the remaining powder layers. In addition, disclosed is A BLISK, compressor blade, turbine blade or turbine component formed by a method. | 03-17-2016 |
20160115939 | SYSTEM AND METHOD FOR CONTROLLING BONDING MATERIAL IN A WIND TURBINE BLADE - A wind turbine blade includes a first shell member including a first mating surface along a first edge of the wind turbine blade. Also, the wind turbine blade includes a second shell member including a second mating surface along the first edge of the wind turbine blade, wherein the second mating surface is opposite to the first mating surface. Further, the wind turbine blade includes a bonding material disposed between the first mating surface and the second mating surface and configured to bond the first mating surface to the second mating surface. Moreover, the wind turbine blade includes a constrainer positioned at a desired bond line and coupled to one of the first mating surface and the second mating surface, wherein the constrainer is configured to restrict the bonding material from migrating into an interior cavity of the wind turbine blade. | 04-28-2016 |
