Description

Bayraktar UAV Aerodynamic CFD Simulation, ANSYS Fluent Training

Introduction

An unmanned aerial vehicle from Turkey is called the Bayraktar. It is a long-lasting, medium-altitude drone. It can be used for surveillance and reconnaissance.

It has a top speed of more than 220 kilometers per hour. The drone has a fuel capacity of 300 liters. The range can go up to 300 km. 5.48 kilometers is the operational altitude. The greatest height is 7.62 kilometers Maximum loitering time for this drone is 27 hours.

In this simulation, a Bayraktar UAV with one propeller rotating around the horizontal axis is modeled using ANSYS Fluent software. The device is moving at a speed of 140 km/h.

The geometry of the present model is three-dimensional and has been designed using Design Modeler software. We do the meshing of the present model with Fluent Meshing software. The mesh type is Polyhedra, and the element number is 1,199,753.

Methodology: Bayraktar UAV CFD Simulation

The Multiple Reference Frames (MRF) method is used to model the rotational motion of the propeller.

Conclusion

Following the completion of the simulation process, vectors and contours for variables like pressure, velocity and turbulent intensity were acquired. The vortexes behind the propeller are visible, as evidenced by the velocity contours. Good dynamic stability is obtained as a result of the Reverse V- tale opposition to the vortexes.

In the static pressure parameter case, as it was predictable, the UAV’s front surfaces endure the highest pressure. The maximum static pressure is applied to the propellers’ edges, which tells us about the necessity of the manufacturing focus on this component.
