3. Results and Discussion 3.1. Geometric Models and Flow ParametersCFD simulations performed in Star CCM+ generate the property tables for the lift coefficient and the drag coefficient against the angle of attack and Mach numbers for NACA 2411 airfoil. This airfoil was selected due to its high lift-to-drag ratio and broad applications in earlier research for multirotor studies.

1. IntroductionTraditionally, computational fluid dynamics (CFD) simulation and wind tunnel experiments have been the main methods for obtaining the external flow field of obstacles. However, these methods are associated with substantial costs and time requirements. With the development of the computer science field, deep learning has seen rapid growth in applications such as speech recognition [1], image recognition [2], and natural language processing [3] in recent years.
