Research on the Motion Characteristics of Trans-Media UAV Out of Water

In order to explore the motion characteristics of the trans-media unmanned aerial vehicle (UAV) dehydrated from the water surface into the air, this paper establishes a physical model and numerical simulation, and deeply analyzes the water movement process of the trans-media UAV from three aspects: dehydration characteristics, flight attitude control and motion stability, revealing its complex motion behavior characteristics. In the part of design and construction, the structural characteristics and basic design principles of trans-media UAV are discussed in detail. In the physical model part of the water outlet process, the complex phenomenon of trans-media UAV dehydration is emphatically discussed, and the trajectory of UAV is deduced by using advanced formulas. In the study of water outlet characteristics, the attitude control stability of UAV in the air is analyzed, and the restrictive effect of aerodynamic factors on UAV movement is revealed. The experiment simulation results show that the UAV is influenced by the coupling of hydrodynamic and aerodynamic forces on the water surface during the dehydration process, and its water outlet angle and speed have an important influence on the subsequent flight. In addition, the trans-media UAV can effectively control its attitude and enter the air stably after it leaves the water, which is of positive significance for promoting the development of UAV technology in the trans-media environment.
