摘　　要：为了研究水池环境对水上飞机全机模型试验结果的影响,在该领域首次采用同一个水上飞机全机模型在两个拖曳水池进行系列全机模型试验,研究全机模型在两个拖曳水池的气动特性和水动特性,分析试验结果和环境差异。结果表明:拖曳水池环境对全机模型的气动特性有明显影响,但通过对全机模型在每个试验水池中的气动特性进行气动力补偿,进行自由拖曳试验时可最大程度地避免试验环境对水阻力结果的干扰,从而获得较为满意的水阻力试验结果;拖曳水池边界效应中,阻塞效应对全机模型的气动特性影响最大,阻塞比2.51%相对阻塞比0.67%时全机模型气动阻力系数大0.1~0.2,升力系数大至少0.2;进行气动力补偿时选用典型的高速滑行状态来计算,故仅在对应速度时补偿效果达到理论值,在其他速度会有一定偏离,导致试验结果也有一定的误差,但因误差较小,不会对试验结果造成明显的影响。研究成果可为中国水上飞机的模型水动试验和性能分析提供指导。In order to study the influence of the tank environment on the results of the seaplane model test,for the first time in this field,a series of whole aircraft model tests were conducted using the same seaplane model in two towing tanks to study the aerodynamic and hydrodynamic characteristics of the whole aircraft model in the two towing tanks,the test results and environmental differences were analyzed.The results show that the towing tank environment has a significant impact on the aerodynamic characteristics of the seaplane model,but by compensating the aerodynamic characteristics of the seaplane model in each towing tank during the test,the interference of the test environment on the water resistance results could be avoided,so as to obtain a more satisfactory water resistance test result.Among the boundary effects of the towing tank,the blockage effect has the greatest impact on the aerodynamic characteristics of the seaplane model.Compared with 2.51%relative blockage ratio 0.67%,the aerodynamic drag coefficient of the seaplane model is 0.1~0.2 larger,and the lift coefficient is at least 0.2.Because the typical high-speed coasting state is used for aerodynamic compensation to calculate,so the compensation effect is only achieved at the corresponding speed and produce some deviation at other speeds,resulting in a certain deviation in the test result,but it will not have a significant impact on the test result because the deviation is so small.The research findings provide guidance for model hydrodynamic tests and performance analysis of seaplanes in China.
