摘　　要：为获取优化的实验尺度水下滑翔机水平机翼外形,基于CFD方法建立了滑翔机仿真模型。分析了平板机翼各参数间的关系,结合滑翔机特性,将机翼的表征量简化为安装位置、后掠角、展长、展弦比和根梢比等5个设计参数。通过对比分析各参数对升阻比的影响,提出了一种适用于实验尺度滑翔机的高升阻比水平机翼。仿真研究了设计的机翼对滑翔机运动的影响,结果表明,滑翔机各状态变量快速收敛,保证了滑翔机在水池环境中的稳态滑翔时间。To get a better wing designing for the laboratory underwater glider, a simulation model was made based on CFD. After the analysis of different parameters of the wing and the characters of glider, the five parameters as position, angle, length of the wing, aspect ratio, root shoot ratio are selected to be compared for the design. After the comparison, a plat wing with higher lift-drag ratio for the laboratory underwater glider was designed. The experiment with the new plat wing indicated that the new design worked better and guaranteed the stability of the underwater glider.
