  Improved stud configurations for attaching laminated wood wind turbine blades Technical Report Faddoul, J R In order to improve joint strength for bonded studs in laminated wood structures (wind turbine blades) a series of designs was developed and ://   [14] J. Faddoul, "Improved stud configurations for attaching lamin ated wood wind turbine blades," in DOE/NASA/, NASA TM 09, ed: NASA: National Aeronautics and Space Administration, Improved stud configurations for attaching laminated wood wind turbine blades. A series of bonded stud design configurations was screened on the basis of tension-tension cyclic tests to   Wind turbine rotor blades are a high-technology product that must be produced at moderate cost for the resulting energy to be competitive in price. This means that the basic materials must provide a lot of long-term mechanical performance per unit cost and that they must be efficiently manufactured into their final form, including the cost of

  Bearing in mind the number of load cycles of a wind turbine as estimated above it is worth noting that the industry standard in fatigue life experimental validation is limited to 2–5 million cycles for blades, and 10 million cycles for coupons; this is a small fraction of the actual number of fatigue cycles sustained by the ://   Typically, wind turbine blades require repair after each 2–5 years, thus, creating the permanent factor of costs increase for wind energy industry. The wind operations and maintenance (O&M) market is expected to reach $ billion by for. The blades of the turbine vibrate individually—the energy associated with those vibrations cannot be used. Finally, the turbine uses some of the electricity it generates to run pumps for gear lubrication, and to run the yaw motor that moves the turbine blades into the most favorable position to catch the 32 33RADIATION TECHNOLOGIES: VIEW FROM RUSSIA Conventional X-ray tubes are still commonly used to image small objects and penetrate through steel that is up to 10 cm thick. Electron linear accel- erators with energies of 1 to 9 MeV are effectively used to scan denser objects such as turbine blades, engines or heavy cast- ://
