摘要： A method of forming a wind turbine blade is provided which includes upper and lower blade mold halves, and a shear web having at least one aperture formed therein. A plurality of bulkheads are attached to the shear web and the shear web can be lifted and rotated, without need for a complex gantry/galactica apparatus, to be placed inside the lower blade mold. The upper mold half can then be closed with the shear web and bulkhead(s) disposed within the blade interior. A heating fluid can be pumped into the interior to pass through the bulkheads, circulating around the shear web and exiting the blade root with the assistance of a sump to pull the cold air outside the blade.

摘要： A method of manufacturing a casting is provided and includes establishing desired dimensions of a nominal casting, executing a casting process to produce multiple actual castings with each of the multiple actual castings having respective dimensions that differ from each other and from the desired dimensions of the nominal casting and engaging one or more tools to adaptively machine, without rigidly-programmed toolpaths, each of the multiple actual castings to reduce the respective differences between the actual dimensions of each of the multiple actual castings and the desired dimensions.

摘要： The invention relates to a method for establishing a sectional or modular wind turbine blade. The method comprises the steps of transporting at least two blade sections of said wind turbine blade and a mobile factory for joining blade sections to a location at or in proximity of a wind turbine site, positioning said blade sections with two blade section ends facing each other and supported on a platform in said mobile factory, moving said platform in relation to the ground at the location for levelling said platform, aligning said blade section ends in relation to each other, and establishing said sectional or modular wind turbine blade by joining blade sections in an area of connection at said blade section ends.
The invention also relates to a system for establishing a sectional or modular wind turbine blade and a mobile factory for joining sections of a wind turbine blade.-

摘要： A method for modifying an aperture in a component, a system for modifying flow through a component, and a turbine component are disclosed. The method includes providing a substrate having at least one aperture having an electrically-conductive surface, providing a deposition device including an ESD torch, the ESD torch including an aperture penetrating electrode including a conductive material, inserting the aperture penetrating electrode at least partially into the aperture, and generating an arc between the aperture penetrating electrode and the electrically-conductive surface to deposit electrode material within the aperture. The system includes the ESD torch removably supported in an electrode holder. The turbine component includes at least one aperture having an electrospark deposited material along an electrically-conductive surface, the electrospark deposited material providing modified fluid flow through the turbine component.

摘要： A method of forming a gas turbine engine component according to an example of the present disclosure includes, among other things, forming a plurality of internal channels in a main body between one or more internal ribs, and forming a weld pattern in an external surface of a cover skin. The weld pattern is based on at least a geometry of the one or more internal ribs. The method includes positioning the cover skin along the main body to enclose the plurality of internal channels, and welding the cover skin to the main body along the weld pattern subsequent to the positioning step.
