Company installs the world's largest onshore wind turbine with mind-blowing feature: 'Set two new global records'

With 430-foot blades and an 885-foot rotor, a new wind turbine in China is set to power 160,000 households annually.
Chinese company Sany Renewable Energy, which installed the 15 MW unit at a plant in Tongyu, Jilin province, says it's the world's largest onshore wind turbine to date.
"This remarkable achievement set two new global records for the largest single-unit capacity and the largest rotor diameter for onshore turbines," Sany said via LinkedIn.
According to Interesting Engineering, the turbine's massive blades result in a greater swept area and capacity, but they also pose a challenge — as blade length increases, greater stiffness and strength is required to avoid issues like stall, classical vibration, and even blade breakage. Sany addressed these concerns by utilizing an aerodynamic design that enhances the blade's overall absolute thickness and improves its structural integrity.
