The present work is to design a passive pitch-control mechanism for small horizontal axis wind turbine (HAWT) to generate stable power at high wind speeds. The mechanism uses a disk pulley as an actuator to passively adjust the pitch angle of blades by centrifugal force. For this design. aerodynamic braking is caused by the adjustment of pitch angles at high wind speeds. https://parisnaturalfoodes.shop/product-category/face-toner/
