EFFECT OF PROPELLERS NUMBERS AND HORIZONTAL DISTANCE IN DESIGN OF VTOL

Nowadays, unmanned aerial vehicles with vertical take-off and landing (VTOL) capabilities are increasing. One of the reasons is that these vehicles can take off and land even in difficult conditions and does not need any runway. In design stages of unmanned aerial vehicles, certain design criteria are taken into consideration. VTOL vehicles, which are divided into tilt-wing or tilt rotor, used in areas such as operation areas, efficiency and cost advantage. In this study, CFD analysis is performed to determine the optimum configuration of the VTOL vehicle by considering the horizontal distance between the propellers and the number of propellers of a tilt-wing unmanned aerial vehicle. For this aim, effect of aerodynamic parameters such as thrust, velocity etc. of propellers are investigated. As a result of this study, the suitable propeller position on the wing and number of propellers for the VTOL vehicle are determined.
