结合工程设计经验和工程计算方法,针对飞行器动导数计算方法展开研究.基于求解准定常欧拉方程发展了一种适合于亚跨超声速状态下,任意气动外形气动导数的高效计算方法,并将计算结果与一般非定常方法的求解结果以及国际标准实验数据进行了对比,研究结果表明该方法结果可靠、效率较高.
A high efficient method for computing dynamic derivatives of aircraft based on quasi-steady CFD method
This article considers the experiences of engineering design and engineering calculation method, based on the quasi-steady Euler equations to solve arbitrary aerodynamic shape which can be fit for subsonic flow, transonic flow and supersonic flow with high efficient. Compared to the calculation results of the general method with unsteady solution and experimental data, the results show that the method is reliable and efficient.
