Image method ideal vortex model is used for the analysis of how ground effect impacts wingtip vortex and airflow downwash angle.
计算结果给出了地效飞行器气动性能随飞行高度和迎角的变化规律;采用镜像法理想涡模型分析了地面效应对翼尖涡位置和气流下洗角的影响;详细阐明了地面效应对诱导阻力的影响规律。
The measurements of the separated vortex field and forces for drag plate show that the nose up pitching moment is produced due to the large induced downwash angle from the separated vortices of drag plate at the tail.
在ＮＨ－２风洞中对某机放减速板产生较大抬头力矩的机理进行了研究，通过减速板分离涡场的测量和测力试验表明，抬头力矩主要是由减速板分离涡在平尾处产生较大的诱导下洗角所致，诱导下洗角沿机身轴线向后逐渐减小，减速板前移可以消除抬头力矩。
