mills were characterized by asymmetry since half of the rotor was screened with a wall. The Chinese windmills (approx. 1000 A.D.), also built with a vertical axis, used the braided mats as sails with no screening wall and therefore they had the typical advantage of vertical axis windmills for omni-directionality which

TSR x 60 / (6.28 x R), Cp = Rotor efficiency, N = Efficiency of driven machinery, A = Swept rotor area (m2), V = Wind speed (m/s) TSR = Tip Speed Ratio, R = Radius of rotor, Rotor efficiency can go as high as Cp = 0.48, but Cp = 0.4 is often used in this type of calculations. This concept works without transmission. If a transmission

CHAPTER 7 Design and development of small wind turbines

Design and Development of Small Wind Turbines 263 can be put into three categories: rotor aerodynamics, rotor overspeed control, and rotor manufacturing considerations. 1.2.1 Rotor aerodynamics In the early days of grid-connected wind turbines, rotors were usually "stall-con-trolled", i.e. maximum power was limited via aerodynamic stall.
