Windpower Engineering and Development
Using an FMEA approach to quantify value of an RTD. (Feb./2016)
Windpower Engineering and Development
Several years of monitoring drive train loads on a range of turbines show how frequently occurring wind events and those common to normal operations abuse drive trains and shortens gearbox life. (April/2015)
Windtech International
Although wind turbines have been around for decades, recent research has been focused on what occurs with a wind turbine under various wind conditions. New data shows how the entire drive-train sees an impact from these transient events. Drive-train torque monitoring on various turbine models has shown that an asymmetrical torque control device reduces the damaging loads and helps extend turbine life.

Bearing News
Modern Wind turbines are an important piece of our energy mix. Unfortunately, gearbox life issues have impacted their financial payback and axial cracks in have become the major cause of premature gearbox failures, shortening life to as little as 1-2 years. The root cause must be understood tosuccessfully find the solution. (February/2015)
Windpower Engineering & Development
Axial cracking in bearing races has become all too common in large megawatt turbines. This damage can shorten bearing life to as little as one to two years. Recent research suggests a root cause of axial cracking, making prevention and early detection possible. (2014/February)
Windpower Engineering and Development
Premature gearbox failures have plagued the wind turbine industry for decades, and only recently have the real culprits been identified. That information has led to a solution not as complex as imagined. (September 2012)
Windpower Engineering and Development
It’s not often that a technical conference leaves attendees with an ah-ha moment, but it happened at the recent Gearbox Reliability Collaborative sponsored by NREL at its offices in Golden, Colo. All presentations were good, but three in particular answered interesting questions raised by those preceding. AeroTorque (then PT Tech Windproducts) did just that! (Article by Paul Dvorak - May 2012)
Wind Systems Magazine
Searching for the root causes of White Etch Area damage and other failure modes. (2013/July)
