基于雷诺平均Navier-Stokes控制方程和非结构网格旋转/静止滑移面技术,开展了临近空间螺旋桨桨梢小翼构型气动布局与增效作用机理研究,采用静止与旋转域的多块网格布局策略及转/静滑移面技术,发展了高效的螺旋桨流场与性能分析方法;通过开展上翘小翼、上下翘小翼等多种桨梢小翼螺旋桨布局研究,初步建立了基础参数的性能影响规律,研究表明:桨梢小翼螺旋桨布局是临近空间工况环境提高气动效率的一种合理可行的技术途径。
Based on the Reynolds- Averaged Navier- Stokes equations and the sliding patched- zone interface technology, combined with the technology of the unstructured grid generation, the study of aerodynamic configuration and synergistic mechanism of proplet propeller is carried out in this paper. Applied to the multi- block grid technique with the static and rotating domain, The high efficient methods of the flow field and the performance of the proplet propeller is developed. The performance influence of the basic geometry parameters for the various proplet configurations are researched deeply. The test shows that the proplet propeller configurations is an reasonable and feasible way to improve the aerodynamic efficiency for near space airship.
