In recent years, the use of unmanned aerial vehicles has increased rapidly. These vehicles have instant detection, tracking and destruction capabilities in military operations. In addition, when compared other conventional aerial vehicles, in the case of the vehicles down, any loss of driver life can be accounted for the most important factor in the view of widespread use of this vehicle. It is very important to make aerodynamic analyzes of unmanned aerial vehicles swarming behavior and to identify reliable zones for vehicles. It should be determined at what speeds and closeness of the flying vehicles along the specified routes the vehicles should be located within the frame. In this study, the models of an unmanned aerial vehicle and propellers of an UAV were designed with computational fluid dynamics. Especially turbulence, pressure, and speed changes have been investigated. Moreover, the range of interaction distance that they can create on each other is determined and reliable regions are determined.

The ancient Mediterranean genus Scorzonera L. is a member of the family Asteraceae, subfamily Liguliflorae, tribe Cichorieae. About 160 species of the genus are widely distributed in Eurasia, Central Asia and Africa. Turkey is considered as a diversity centre for the genus with its 52 species, 31 of which are endemic (Altınordu et al. 2015; Coşkunçelebi et al. 2015). Some Scorzonera species have been used as a vegetable (raw or cooked).
