S; Ms. Devadarshini P; Mr. Balachandar R; and Mr. Prajith V on October 13, 2026, for A Vertical-Axis Wind Turbine System With Passively Adaptive Flapping Blades And Phase-Controlled Return Stops.
Inventors include Mr. Babu T; Dr. Rajesh S; Dr. Parswajinan C; Ms. Janani G; Ms. Jayapradha S; Mr. Hitesh Kumar P; Mr. Yuddeesh A. S; Ms. Devadarshini P; Mr. Balachandar R; and Mr. Prajith V.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A vertical-axis wind turbine system includes a vertical rotor shaft (100), radial support arms (120) and circumferentially distributed blade assemblies (110). Each assembly includes a blade panel (130) mounted about an offset, substantially vertical pivot (140), a passive biasing element (150), a deployed-position stop and a return stop (160). Aerodynamic hinge moments generated during rotation cause the panel to assume a torque-producing deployed orientation during a favorable sector and a reduced-projected-area orientation during a return sector. The stops bound blade travel and the biasing element promotes repeatable return to the deployed orientation. Adjustable stops, resilient contact inserts and an optional damping element (170) can reduce oscillation and impact loads. The system can be fabricated using conventional sheet, hinge and support-arm components and may drive an electric generator without individual powered blade-pitch actuators.
