基于射流控制的分布式推进无人机纵向稳定性控制方法
By combining jet control technology with tail array, jet parameters are adjusted in real time to counteract the pitching moment problem during the take-off and landing of the UAV, thus solving the longitudinal static stability problem of the distributed propulsion UAV during the take-off and landing phase and achieving stable flight in the low-speed range.

AI Technical Summary
Distributed propulsion short takeoff and landing (STOL) drones experience excessive pitching moment due to the slipstream lift effect during takeoff and landing, leading to loss of longitudinal static stability and posing risks of pitch oscillation and stall, thus affecting flight safety.
By employing jet control technology, jet parameters are adjusted in real time through tail jet array and closed-loop control to counteract the excessive nose-up moment caused by slipstream. A mapping relationship is established between longitudinal moment coefficient and velocity, angle of attack, and jet parameters, thereby achieving active control of tail aerodynamic characteristics.
It precisely counteracts the pitch-up moment caused by the slipstream, ensuring that the drone maintains a stable attitude in the low-speed range, improving longitudinal static stability, adapting to drones of different shapes and sizes, and is easy to modify without requiring major reconstruction of the fuselage structure.
