Abstract :Propulsion systems are one of the most important components of aircraft that affect their performance. While designing the propulsion system, researchers need to design the position of the propulsion system according to the requirements of the aircraft as well as the choice of materials to be used. In this research, the effects of propeller effects on aerodynamic forces, aerodynamic performance and moment coefficients of a delta wing with NACA 0012 geometry and sweep angle of 50 degrees in tractor and pusher configurations were investigated and compared with no propeller (base) configuration. The tractor configuration provided the highest lift. Sharp stall phenomenon is not observed in pusher configuration. When the drag coefficients are examined, it is seen that the drag of the tractor configuration is higher up to 21 degrees, after 21 degrees the drag coefficient of the pusher configuration increases, but still the aerodynamic performance (L/D) of the tractor configuration is higher than the pusher configuration at 12 degrees where they have the maximum L/D ratio. In the pusher configuration, which reattach the separated flow to the surface, the static stability has slightly increased instability, while in the tractor configuration, abrupt changes are seen depending on the stall angle, which requires more attention to the controller design in UAV design.
