摘　　要：根据水上飞机起飞滑行阶段的受力特点,借鉴高速艇阻力性能预报和分析方法,提出考虑水上飞机机翼气动布局影响的半理论半经验公式方法,并采用该方法对水上飞机在静水中中高速滑行时的阻力性能进行估算。以某船身式水上飞机模型为算例,计算其航行姿态、气动阻力、水动阻力和总阻力。将计算结果和模型试验数据进行比对,结果表明,计算模型的气动阻力和水动阻力的计算值随着宽度弗劳德数变化的基本规律与试验结果基本一致。Based on the force characteristics of seaplane at takeoff, a method of combining the theoretical analysis and empirical formula was employed to study the resistance performance of the seaplane of medium and high speed, considering of the aerodynamic distribution effect from the aerofoil and airscrew. The aerodynamic drag, calm water resistance and total resistance of a sample seaplane model were calculated, and the comparison between the calculations and experiments showed that the calcula- tion values of the aerodynamic drag and calm water resistance were consistent with the experiments in the variation trend along with the Froude number.
