In this paper. the aerodynamic performance of a Hex-rotor unmanned aerial vehicle (UAV) with different rotational speeds (1500−2300 RPM) considering the horizontal airflow conditions is analyzed by both simulations and experiments. A low-speed wind tunnel experiments platform is applied to measure the thrust. torque. https://lecoureures.shop/product-category/course-a-pied-homme-vetements-cuissard/
