abstract = {Active flow control, which dynamically manipulates flow structures by injecting energy into the flow field, presents an innovative strategy to fulfill the high-lift requirements for aircraft operating under Short Takeoff and Landing (STOL) conditions. To assess its practical efficacy, this study developed an integrated control system that combines dual synthetic jet actuators-designed to control flow separation on control surfaces-with a multi-stage circulation control system aimed at augmenting wing lift. This system was deployed on an aircraft platform featuring a 5 m wingspan and a takeoff mass of 100 kilogram class for flight testing. The flight test in November 2025 results revealed that the dual synthetic jet lift-enhancement system significantly improved takeoff and landing performance: the takeoff rotation speed decreased from 26 m/s to 21 m/s, the ground roll distance was reduced from 156 m to 101 m, and the landing touch-down speed declined from 25 m/s to 20 m/s, and the landing energy was lowered by 36%. Furthermore, the achievement of a stable roll rate of 3.8 (°)/s through asymmetric actuation directly demonstrates the capacity of system to generate asymmetric lift and rolling control moments via precise flow manipulation. This work represents the first flight validation of a passive dual synthetic jet lift-enhancement technology on a medium-scale aircraft platform, thereby offering an innovative, efficient, and independently controllable technical approach for advancing aircraft STOL capabilities.}
