Question
Why Blade Numbers are essential and needed to be considered in establishing the design of a wind energy conversion system (WECS) please answer at your own words and make it long essay if you can. Thank you so much!
Blade Numbers Single Blade Double Bladed Three Bladed resembles an airplane wing. hs The aerodynamic efficiency and cost of a wind turbine design often dictate how many rotor blades it has. While most horizontal axis wind turbine generators only have one, two, or three rotor blades, the ideal wind turbine design would have numerous thin rotor blades. More than three rotor blades are typically not needed. However, compact, fast-spinning multi-bladed turbine generators are available for household use. Nevertheless, adding more rotor blades results in just a minor improvement in rotor efficiency and increases the cost of the rotor.
