AI Technical Summary

Technical Problem

Multi-rotor drones have low aerodynamic efficiency and short endurance, while helicopters have complex control mechanisms and are difficult to maintain.

Method used

It adopts a heterogeneous multi-rotor layout with a coaxial main rotor and two vector slave rotors. The large coaxial main rotor provides lift, while the two vector slave rotors independently provide control torque. Functional decoupling is achieved by adjusting the tilt angle and speed of the vector slave rotors.

Benefits of technology

It improves aerodynamic efficiency, enhances endurance, simplifies mechanical structure, and improves handling performance and maintainability.
