摘要
Abstract
A trans-media unmanned aerial vehicle (UAV), flying near water surface, cannot obtain steering force by conventional air rudder, which results in difficult steering and poor maneuverability of the UAV. A slide jump steering method of the UAV on water surface and a dynamic model of slide jump steering flying of the UAV are hence proposed in this paper on the basis of the aerodynamics, the classic potential flow theory, and the two-element plane sliding theory. The slide jump steering characteristics of the UAV and the influencing factors are simulated with the model and analyzed in detail. Moreover, some approaches for inhibiting UAV roll are given. Simulation results show that the water-entry angle and the fixed rudder angle of the UAV impose significant effects on its posture and trajectory pattern in the process of slide jump steering. This study may provide theoretical and calculation foundation for the UAV's conceptual overall design, trajectory planning, flight reliability design and flight control system design.关键词
