MFG Energy Services recently teamed with WINDprove (Davis, CA) and CNT Metal Solutions (Spring Valley, CA) on a funded research project to develop an innovative method for replacing the aluminum root of the V-47 turbine blade with a fiber glass insert using bonded studs. After 14 or so years of field service, many of these workhorse turbines are experiencing blade root problems.

The team’s innovative approach involved fabricating a replacement root insert (developed at MFG Texas) and a portable boring machine for removing the original root insert and creating a surface to receive the new root. Successfully proven in the shop, the solution is now trailer-mounted for field service.

The innovation promises to add years of productive life to V-47’s.
