20 meters. On a wind turbine blade with a radius of 85 meters, a torque with a diameter of 20 meters is required to successfully drive the 85 meter blade. Therefore, the torque of a blade with a radius of 85 meters is 20 meters. Wind turbines are electrical equipment that convert wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current.
This fan blade is approximately 70 meters long.
According to the official wind turbine website, the main blade shapes of wind turbines are 126, 110, 114, etc., and the corresponding blade sizes are now 68m, 54m, 56m. the largest wind turbine blade diameter exceeded 70 meters, the equivalent of the wingspan of a Boeing plane.
This fan blade uses wind energy to produce electricity. The design of the wind turbine blade directly affects the conversion efficiency ofe wind energy and directly affects its annual energy production. use.
