Inspection of Composite Turbine Blades with Ultrasonic Phased Array Technology
Ultrasonic phased array can be used to inspect wind blades with low-frequency probes to detect and size small flaws and defects such as wrinkles, delamination, disbonds, and more.
1. Introduction In-service wind turbines operate in harsh environments. While the wind blades are subjected to a high-level of stress, other components of wind turbines are also exposed to difficult conditions. To help ensure the integrity of wind turbines when in-service, it is important to apply efficient and reliable nondestructive testing methods. This paper focuses […]
New high-performance main bearing solutions for wind turbines
A new bearing design is able to perform under high-thrust loads while still maintaining its excellent misalignment characteristics.
Today’s modern wind turbines can produce more than 7 MW of electrical power per unit — with offshore prototypes capable of achieving an output of as much as 12 MW — making these majestic machines an indispensable source of energy to help mitigate the detrimental effects of climate change. Consequently, ensuring that wind turbines operate […]
