If a turbine is more efficient than a propeller for planes producing wind force, why isn’t it used for wind energy the other way around?
In: Engineering
A propellor without power is a turbine if you blow on it. However, propellor blades are designed for high rotational speeds from the engine being on and also high air speeds from flying on a plane. On the other hand wind turbine blades are specially designed to have optimum aerodynamics at the rotation and air speeds involved with wind power. In fact turbine blades adjust their shape to do this better at a range of speeds. Propellers can do this too but designed for a much “higher speed” range of speeds.
