论文摘要
本文重点介绍了空气动力学的计算预测以及在其高产(HL)配置中,NASA共同研究模型(CRM)的流场特征非常接近地面。检查了带有Spalart-Allmaras(SA)湍流模型的Urans模拟,以了解生成的网格的质量,并将其与可用的风洞数据进行比较。在地面附近获得的模拟结果表明,飞机银行位置的纵向和侧向空气动力学特性发生了显着变化,这对于更好地理解在交叉条件下飞机着陆很重要。
This paper focuses on computational prediction of aerodynamic and the flow field characteristics for NASA Common Research Model (CRM) in it's High-Lift (HL) configuration in close proximity to the ground. The URANS simulation with the Spalart-Allmaras (SA) turbulence model is checked for the quality of the generated mesh and compared with the available wind tunnel data. The obtained simulation results in the immediate vicinity of the ground demonstrate significant changes in the longitudinal and lateral-directional aerodynamic characteristics in aircraft banked positions, which is important for a better understanding of aircraft landing in crosswind conditions.
