Multiple double-row, four-point bearings of three different sizes are tested on four different test rigs, and the friction torque at different bending moments and axial loads of the bearings are measured, resulting in significant discrepancies in the torque of identically sized bearings.

The friction torque of rotor blade bearings is a required parameter for the design of pitch actuators and may provide information about continued degradation and impending failure of the bearing. The torque is heavily influenced by the operating conditions and external loads acting on the bearing. Test results for real-size bearings under realistic loads are […]

With the Corlacky Hill Wind Farm in northern Ireland, the RES Group reveals why Lidar is widely trusted for wind resource assessment.

Our ability to harness the power of the wind plays a pivotal role in the transition to a greener and more sustainable future. Staring down the pressing challenges of our changing climate, environmental degradation, and the transition away from our reliance on depleted fossil fuels, wind power represents one of the most scalable and cost-effective […]
