This study examines how the aerodynamic performance enhancements in Micro Aerial Vehicles (MAVs) through the application of low-profile Vortex Generators (VGs) on rectangular wings. Computational simulations, employing the SST k-ω turbulence model at a Reynolds number of 100,000, were combined with the Response Surface Method (RSM) to determine the optimal VG configuration for enhanced performance at a 10° Angle of Attack (AOA). The results reveal significant improvements in boundary layer control, leading to delayed flow separation, increased lift, and reduced drag. Specifically, the optimized VG configuration reduced drag by 26% while moderately improving lift. These findings demonstrate the efficacy of VGs in enhancing MAV flight efficiency, offering a crucial solution for low-Reynolds-number aerodynamic challenges. This work contributes to the design optimization of MAV wings for better maneuverability and endurance.
