Variable Structure Water-Air Amphibious Trans-media Vehicle Concept Design and Characteristic Analysis
摘要
As it is difficult to adapt a single unmanned platform to complex and changing mission types and working environments, this paper designs a variable structure water-air amphibious trans-media vehicle for reconnaissance and detection, as well as a simulation analysis of its hydrodynamic characteristics. This is followed by kinematic modelling and mathematical calculation analysis. Finally, the hydrodynamic characteristics of the fuselage of the vehicle are analysed, with respect to the hydrodynamic drag characteristics of the vehicle fuselage and the hydrodynamic drag of the vehicle at different wing folding angles. The paper finalises the design of a variable configuration water-air amphibious vehicle, while the specific effects of different wing folding angles on the hydrodynamic characteristics of the fuselage are compared through a combination of simulation and mathematical analysis.
