摘要
利用结构网格计算流体力学(Computational fluid dynamics,CFD)的翼型气动特性分析方法开展旋翼翼型气动特性计算。通过RAE282,NACA0012,OA212,OA207等翼型压力分布、升力和阻力等特性计算结果与试验结果的对比分析,验证了计算方法的准确性,并进一步完成了HF系列旋翼翼型的气动特性计算。基于翼型的气动特性,采用时间步进自由尾迹的旋翼气动性能分析方法开展旋翼桨叶翼型的气动布局优化设计,对悬停和前飞条件下的旋翼开展计算分析,得到两种条件下的旋翼气动特性。而后通过本文建立的优化方法开展旋翼翼型布局优化设计。
The aerodynamic characteristics of the airfoil were calculated by using the aerodynamic characteristics of the computational fluid dynamics(CFD), and the results were compared with the experimental results of RAE282,NACA0012,OA212,OA207 and other characteristics. The accuracy of the calculation method was verified. Based on the aerodynamic characteristics of airfoil,the time step was incorperated into free vortex aerodynamic performance analysis method to carry out the rotor blade airfoil aerodynamic configuration optimization design. Hover and fly under the condition of the rotor were calculated and analyzed,and the rotor dynamic characteristics were obtained. Finally,the optimized layout of rotor airfoil was designed.
