主动流动控制技术通过向流场主动施加能量实现对流动结构的动态调控与优化，为飞行器短距起降的高升力需求提供了全新技术方案。为评估主动流动控制技术在飞行器短距起降（STOL）场景下的实际效能，基于中国自主可控的合成双射流技术，设计了襟翼流动分离控制与机翼多级环量协同增升控制系统，集成于翼展5 m、起飞质量百公斤级飞行器平台并开展了飞行试验验证。2025年11月首飞试验结果表明：合成双射流增升控制系统显著提升了飞行器起降性能，起飞离地速度由26 m/s降至21 m/s，滑跑距离由156 m缩短至101 m，着陆接地速度由25 m/s降至20 m/s，着陆能量降低36%。此外，飞行器在非对称控制下产生3.8 （°）/s稳定滚转角速度，直接证明了合成双射流通过流场调控可有效产生非对称升力与滚转控制力矩，也进一步验证了合成双射流增升的有效性。研究实现了无源合成双射流增升技术在百公斤级中型无人飞行器平台上的飞行验证，为飞行器短距起降提供了一条自主可控、高效集成的创新技术路径。

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.
