飞机结冰是影响飞机飞行安全的重要因素之一,研究结冰对飞机气动性能的影响具有重要意义。应用多块结构化网格生成方法,通过求解雷诺平均N-S方程分别对翼型及DLR-F4翼身组合体干净外形和三种不同带冰外形的流场进行计算,分析不同冰型对翼型及翼身组合体绕流流场及气动特性的影响。
Aircraft icing is one of the important factors that affect the flight safety of aircraft. Studying the influence of icing on the aerodynamic performance of aircraft is of great significance. The multi-piece structured grid generation method is used to calculate the clean shape of the airfoil and DLR-F4 wing-body assembly and the flow field of three different ice-shape configurations by solving the Reynolds-averaged Navier-Stokes equations. And wing body flow around the body and aerodynamic characteristics of the impact.
