Abstract: A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments includes at least one shell member defining an airfoil surface. The rotor blade also includes pin joint(s) for connecting the first and second blade segments at the chord-wise joint. The pin joint(s) includes pin joint tube(s) received within the pin joint slot(s). The pin joint slot(s) are secured within a bearing block. Further, a gap is defined between the pin joint slot(s) and the bearing block. Moreover, the rotor blade includes a shim within the gap between the pin joint slot(s) and the bearing block so as to retain the pin joint slot(s) within the bearing block. In addition, the shim is constructed of a liquid material that hardens after being poured into the gap.

Abstract: A method and portable device for modifying or coating a surface of turbine components in the field includes an ESD torch electrically connected with ESD equipment. The ESD torch includes an inert gas source, vibration source, and electrode disk of conductive material. The electrode disk is disposed within the ESD torch, shielded by an inert gas and coupled with the vibration source. The electrode disk is rolled over the surface, which actuates the electrode disk and deposits the conductive material from the electrode disk onto the surface of the workpiece to form the compositionally controlled protective coating. The compositionally controlled protective coating deposited by the electrode disk forms a metallurgical bond with the surface of the workpiece to prevent erosion of the workpiece.
