Research on propeller parameters and integrated design with aircraft

  • 摘要: 螺旋桨推进具备较高的推进效率和广泛的通用性。由于桨盘面积大、滑流范围广,螺旋桨与载机间的空气动力耦合关系更加紧密,需要将螺旋桨与飞机进行综合设计,迭代获取优化设计方案,从而最大化保证飞机的高性能和经济性。本文首先介绍了飞机总体设计对螺旋桨气动设计参数的影响,以及螺旋桨多目标优化综合设计的手段;然后,简述了螺旋桨布局选型对飞机总体设计的影响,介绍了共轴对转螺旋桨设计和分布式推进螺旋桨设计两种新形态的螺旋桨设计构型;最后,讨论了螺旋桨设计手段的发展,以及CFD方法在螺旋桨-飞机综合设计中的应用。本文可为螺旋桨飞机的相关总体设计和气动优化提供参考。

     

    Abstract: For aircraft, propellers have higher efficiency than other forms of propulsion and demonstrate wide-range versatility. The close aerodynamic coupling between the propeller and aircraft fuselage necessitates a comprehensive design of propeller-driven aircraft for better performance. This paper first introduces the requirements of aircraft design for propellers, such as but not limited to their diameters, blade numbers, and airfoil configurations, accompanied by the multidisciplinary optimizing design methods for propellers. Then, it examines the ramifications of propeller layout on aircraft design, focusing on two novel propeller configurations: co-axial counter-rotating propellers and distributed propellers. Furthermore, the evolution of propeller design techniques is traced, and the application of Computational Fluid Dynamics (CFD) in computational aeroacoustics, three-dimensional shape optimization, evaluation of aerodynamic interference, and comprehensive aircraft design is summarized. This paper will serve as a valuable reference for designing and optimizing propeller-driven aircraft.
