基于Open VSP非定常/准定常涡格法的螺旋桨快速气动评估
Propeller rapid aerodynamic evaluation based on openVSP unsteady/quasi-steady vortex lattice method
摘要
Abstract
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.关键词
