This paper presents a novel orthogonal octo-rotor Unmanned Aerial Vehicle (UAV) and addresses the aerodynamics of the UAV with varied rotor spacing by both numerical simulations and experiments. Compared with the traditional planar multirotor UAV. this novel orthogonal octo-rotor UAV features a compact structure with four horizontal main rotors for stability and thrust and four vertic... https://herbsdailyes.shop/product-category/sarsaparilla-smilax/
