AI Technical Summary
Existing drones have bottlenecks in terms of payload capacity and energy efficiency. Multi-rotor structures have insufficient payload, while traditional helicopters are costly and structurally complex.
It adopts a tandem rigid rotor layout, combining a large main rotor to provide lift and rigid blades, and uses an auxiliary small propeller to achieve separation of attitude control and lift, and employs a closed-loop feedback control system for precise control.
It achieves high payload capacity and high-efficiency flight performance, has a simple structure and low cost, and possesses good maneuverability and stability, overcoming the shortcomings of multi-rotor and traditional helicopters.
