为研究非对称转捩对横向偏离稳定的影响,采用指定位置的强制转捩方法,对典型升力体外形进行非对称转捩的的数值模拟,包含全层流、全湍流及斜线转捩情况的计算与分析,得到非对称转捩对横向偏离稳定性影响的结论。结果表明:极端转捩会使飞行器航向稳定性变差,斜线转捩甚至会使飞行器航向稳定性的极性发生改变。
In order to study the influence of asymmetric transfer on the lateral deviation stability, numerical simulation of asymmetric transfer of the typical lift body shape is carried out by means of forcible transfer at the specified position, including full-layer flow, total turbulence and slanted transfer The calculation and analysis of the results show that the influence of asymmetric transition on the stability of lateral deviation is obtained. The results show that extreme swivel will deteriorate the heading stability of the aircraft, and the swerve transition will even change the polarity of the heading stability of the aircraft.
