AI Technical Summary
Existing cross-medium UAV propulsion systems suffer from structural redundancy, excessive energy consumption, and efficiency imbalance. A single thruster is inefficient in different media, while two independent propulsion systems increase weight and volume and become a useless burden in a certain medium.
It adopts a design that combines a shaftless ducted propeller and a variable-form cycloidal propeller. The inner and outer rotors are coaxially nested. By switching between the unfolded and folded states of the cycloidal propeller, it can adapt to the power requirements of different media underwater and in the air, realizing the embedded integration of the power unit and reducing space and weight.
It improves the propulsion efficiency and maneuverability of cross-medium UAVs underwater and in the air, reduces energy consumption, and enables surfacing, diving, and underwater turning functions, thereby enhancing maneuverability and mission payload capacity.
