针对螺旋桨飞行器概念设计阶段的快速迭代需求，涡格法等低可信度气动评估方法是较为合适的选择。为获得合适的计算参数及定量误差，基于螺旋桨标模研究了NASA开源飞行器设计工具（Open vehicle sketch pad，OpenVSP）非定常涡格法（unsteady vortex lattice method，UVLM），并首次给出了多重参考系准定常涡格法（multiple reference frame quasi-steady vortex lattice method，MRF-VLM）的计算特性。采用 APC电动螺旋桨标模分析了计算收敛性和误差特性，获得了兼顾计算稳定性和效率的网格/迭代参数设置。与试验数据对比表明，在合适的网格和迭代参数下，上述两种方法在低桨距角和中等前进比工况下推进效率计算误差分别在6.1%和3.6%以内，精度满足概念设计阶段要求，且4线程并行的MRF-VLM计算仅需4 min，效率更高。NACA 5868-9螺旋桨标模算例进一步验证了MRF-VLM方法的计算可信度。以上研究结果能够为OpenVSP涡格法可靠工程应用提供参考。但由于涡格法的线化势流理论局限性，上述两种方法在高桨距角和高低前进比下无法准确模拟较强的流动非线性，计算精度有待改善。

In response to the need for rapid iteration in the conceptual design stage of propeller aircraft， low-fidelity aerodynamic evaluation methods， such as the vortex lattice method was a more suitable choice. In order to obtain suitable computation parameters and quantitative errors， the NASA OpenVSP unsteady vortex lattice method （UVLM） was studied using the propeller standard model， and the computation characteristics of the multiple reference frame quasi-steady vortex lattice method （MRF-VLM） were presented for the first time. The computational convergence and error characteristics were analyzed using the APC electric-propeller standard model， and the grid/iterative parameter settings that take into account both computational stability and efficiency were obtained. The comparison with experimental data shows that with appropriate grid and iterative parameters， the computation errors for the propulsion efficiency of the above two methods are within 6.1% and 3.6% respectively， under conditions of low pitch angle and medium advance ratio. The accuracy meets the requirements of the conceptual design stage， and the MRF-VLM computation with 4-thread parallel processing takes only 4 minutes， which is more efficient. The case of NACA 5868-9 propeller standard model further verify the computational reliability of the MRF-VLM method. The above research results can provide a reference for the reliable engineering application of OpenVSP VLM. However， due to the limitations of the linearized potential flow theory of the VLM， the above two methods can not accurately simulate the strong flow nonlinearity under high pitch angle and high/low advance ratio， and the computation accuracy needs to be improved.
