| 摘 要： | 针对水上飞机水面起飞过程阻力峰值较大,提出一种可偏转机翼水翼型水上飞机,飞机水面滑行时偏转机翼割划水面产生水动升力将飞机抬离水面,空中飞行时偏转机翼根据飞行条件可偏转角度。采用空气动力和水动力耦合求解并结合动力学平衡方程方法分析了该布局水动特性并进行空中巡航气动特性分析,同时计算同尺寸双浮筒型水上飞机,比较两种构型水动与气动特性。数值计算结果表明,水面起飞过程中双浮筒型水上飞机总阻力峰值约为水翼型水上飞机偏转机翼布局的1.97倍；飞机空中飞行时,偏转机翼偏转角为0°时气动性能最优且所受阻力低于双浮筒型水上飞机,从而证明了水翼型水上飞机偏转机翼布局能够有效提高水上飞机的水动与气动性能。

| Abstract: | Aiming at the problem of big drag during takeoff for seaplane, a hydrofoil seaplane with deflectable wings is proposed. The hydrodynamic lift generated by deflectable wing cutting the water surface during takeoff is big enough to lift the aircraft off the water surface. The deflectable wing can deflect the angle according to flight conditions during the flight phase. Aerodynamic and hydrodynamic coupling solutions and dynamic equilibrium equations are used to calculate the hydrodynamic performance for hydrofoil seaplane, and the aerodynamic characteristics of air cruise are analyzed. At the same time, the calculation of the same size double-float seaplane is carried out, and the hydrodynamic and aerodynamic characteristics for two configurations were compared. The numerical results show that the peak value of total drag for double-float seaplane is about 1.97 times of that of the deflection wing for hydrofoil seaplane during takeoff. Aerodynamic performance of deflecting wing with 0° deflection angle is optimal and the drag is lower than that of double-float seaplane during flight, which proves that the deflection wing layout of hydrofoil seaplane can effectively improve the hydrodynamic and aerodynamic performance for seaplane. |
