Mechanical Design and Evaluation of a Bionic Aerial-Aquatic Vehicle

This study designs a variable configuration for a bionic aerial-aquatic cross-media vehicle, providing a crucial platform support for the research of cross-media key technologies. Utilizing computational fluid dynamics (CFD) simulation technology, the aero-dynamic characteristics of the prototype at different speeds were analyzed, and the final prototype was successfully developed and tested in flight experiments. The experimental results demonstrate that the aerial-aquatic vehicle can complete the transition between the aerial and aquatic navigation modes through the deformation ability. The maximum flight speed in the air reaches 104 km/h, and when the cruise speed is greater than 54 km/h, the lift-to-drag ratio is greater than 18.623, indicating a good aerodynamic characteristic.
