The ability of the Hybrid VTOL UAV to operate for both hovering and level flight makes it highly appealing. A transitional flight is one in which both the rotors and the forward propeller are active and the interaction between the rotors and the main wing takes place. This phenomenon, which ...
The side by side coaxial VTOL system can utilize variations of the optimum specifications of a coaxial rotor such as the distance between propellers, the diameter of each propeller, and the pitch of each propeller without having to consider an imbalance in torque between the top and bottom propel...
Subsequently, multi-objective optimization and similarity conversion are executed in conjunction with parameter requirements of different modes of the UAV, effectively enhancing landing adaptability and stability of the tail-sitter VTOL UAV.QI Hao
It can to meet many of the requirements of vertical take-off and landing (VTOL) unmanned aerial vehicles (UAVs) for applications in reconnaissance and surveillance. To achieve innovative multi-rotor VTOL UAV dynamics and stability, performance enhancements are required. This is achieved by increasing...
