摘要
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。
The icing problem affects the flight safety of aircraft,exploring the icing effect on aerodynamic performance for aircraft is very important.In the research,three different ice shapes are constructed：sharp-angled ice,blunt nosed ice and double horn ice.The multi-block technology was used to generate grid,the flows of icing models are simulated numerically by solving the Navier-Stokes equations.The results calculated are in good agreement with experimental data and show that our method is correct for the icing research.
