Bladena, comprised of leading industry blade experts and structural/aeroelastic researchers, specializes in providing blade enhancement solutions to counteract cracking and other operational failures. Preventative measures include a patented technology known as the D-String.
Research shows that a significant number of turbine blade failures are bond line related, with trailing edge failures being the most common. These problems are caused by “breathing,” which refers to blade panel deformities induced by heavy loads being exerted during turbine operation. The load changes direction relative to the blade rotation and causes the blade shell panels to bow outward, which is also known as “breathing.” This effect has been identified in the more mature European market where industrial scale turbines have experienced longer fatigue life.
A standard installation of the D-String by Rope Partner certified WindCorps technicians requires 10 to 12 string systems fastened between trailing edge panels effectively stiffening and neutralizing the effect. This will drastically reduce, or eliminate, critical fatigue damage to the blade during operation.
“We announced our partnership at Wind Power 2013 and are already scheduling our first project with one of our clients. Rope Partner is honored to be selected as a partner by Bladena,” Stanfield said.
