AI Technical Summary
The wing deployment drive mechanism of large-wingspan lifting body UAVs occupies too much space, which increases aerodynamic drag, reduces lift-to-drag ratio, and limits endurance.
Design a side wing deployment drive mechanism for a UAV with locking function. By integrating a locking function module into the deployment function module, the rotational deployment of the side wing and the position locking after deployment are realized. A double torsion spring parallel structure is adopted to improve the output torque and realize the locking function in a limited space.
The deployment and locking of the wing were achieved within a limited space, reducing aerodynamic drag, increasing lift-to-drag ratio, extending flight time, and improving the reliability of the locking function.
