本文描述了风洞支撑系统对亚音速过失速条件下CRM飞机外形尾流和相关力的影响。分别使用有和没有支撑杆的CRM进行了,和的非定常尺度分辨模拟。在这些条件下,观察到支杆的主要局部效应,导致支杆附近的局部流动方向发生显著偏转。支腿的形状导致水平尾翼附近的向下偏转,降低了该表面的有效迎角和升力系数。这导致总升力系数减小,机头下仰力矩显著减小。机翼压力分布只受到微弱的影响。
This work describes the influence of the wind tunnel support system on the wake flow and associated forces acting on the CRM aircraft configuration in post-stall conditions at subsonic Mach numbers. Unsteady scale-resolving simulations at,andwere carried out using the CRM with and without a support sting, respectively. A predominantly local effect of the sting was observed at these conditions, causing significant deflection of the local flow direction near the sting. The sting’s shape causes downward deflection near the horizontal tailplane, decreasing that surface’s effective angle of attack and its lift coefficient. This results in a reduced overall lift coefficientand a significantly reduced nose-down pitching moment. The wing pressure distribution is only weakly affected.
