摘要：提出了一种可变形仿生飞翼布局水空跨介质无人机并对该无人机的气动和水动特性进行计算,绘制了该无人机3种空中飞行速度和3种水下速度的升力和阻力曲线。分析结果发现:该无人机通过变形可具备较好的水中和空中航行能力。在空中的升阻比可达12,且可通过在水下翻转的方式抵消正浮力,速度为10 m/s时减阻3.8%。合理设计了兼顾空中飞行和水下航行的组合式操纵面,利用Simulink分别建立了该无人机在空中和水下的动力学模型。所设计的无人机在空中能够通过升降舵和两组副翼的联动控制高度以及航向,在水下能够通过升降舵和由副翼组成的开合式翼控制深度和航向,证明了该方案的可行性。
This paper propose a new Deformable Bionic Flying-wing Aerial-aquatic Unmanned Vehicle(DBFAUV) and calculates its aerodynamic and hydrodynamic data. The lift and drag curves of the DBFAUV at three air speeds and three underwater speeds are drawn. The analysis results show that the DBFAUV can achieve a good navigation ability in water and air through deformation, and its lift-to-drag ratio can reach 12 in the air. It can further counteract the positive buoyancy by overturning underwater to obtain the effect of drag reduction. When the speed is 10 m/s, the drag reduction effect can reach 3.8%. A combined control surface considering both air flight and underwater navigation is then designed. The dynamic models of the UAV in the air and underwater are established by using Simulink. The simulation shows that the UAV designed in this paper can control height and heading in the air through the linkage of an elevator and two sets of ailerons, and can control depth and heading under the water through the elevator and open-and-close wings composed of ailerons, which proves the feasibility of this scheme.
