Our Invention Palm tree inspired blade design for horizontal axis wind turbines is this present invention provides a palm tree inspired blade for horizontal axis wind turbines, where in the turbine tower bends 50 to 80 degrees in stormy conditions without snapping to generate optimal power, as compared to the conventional horizontal axis wind turbines. Due to such chord length and airfoil twist resembling a palm tree leaf blade shape proposes an optimum blade design for the wind turbine in stormy weather conditions. The usage of ‘B-spline curves’ gives the entire blade system sheer strength and malleability of the tower to act like the palm tree stem inclement to withstand the stormy weather conditions without snapping. This bio-memetic concept of palm tree inspired blade design can improve the aerodynamic performance of the horizontal axis wind turbine blade system even in stormy weather conditions, without producing a lower maximum power co-efficient; hence maintaining the higher lift co-efficient even at crucial stormy weather velocities, without snapping or breaking the wind turbine controls.
