An experimental investigation was carried out to understand the effects of LEP (leading-edge protuberance) blades on structural characteristics VAWTs. A series experiments were performed VAWTs with straight and for a wide range wind velocity (6 m/s 20 m/s) pitch angles (−20° 20°), excitations VAWT structure measured using triaxial accelerometer in each case. The raw acceleration data extensively processed time frequency domains identify variation excitation caused by unsteady aerodynamic loads structure. Understanding changes their impact is essential. current study examines how influences However, great deal observed blades, so replaced various modified which similar set out. presents better performance (self-starting, stall-mitigating) 3 2 significant reduction due load aerodynamics along- across-wind directions.
