摘　　要：综合考虑飞机自身稳定性和操纵特性以及飞行员反应时间,提出了飞机遭遇尾流动态响应模型。研究了飞机遭遇尾流后的诱导速度场和诱导滚转力矩系数,通过试验模拟了遭遇尾流对飞机安全性的影响,以及纵向间隔和飞行速度对飞机遭遇尾流严重程度的影响,对飞机遭遇尾流严重程度进行了量化计算。In order to study the dynamic response and severity of the aircraft encountering the wake vortex.The stability and maneuvering characteristics of the aircraft and the reaction time of the pilot were considered.A dynamic response model of the wake encounter of the aircraft was proposed,which was mainly analyzed from the two aspects of the induced velocity field and the induced rolling moment after the aircraft encounter the wake vortex.The safety of the aircraft after the wake was analyzed,and the influence of the longitudinal interval and flight speed on the severity of the wake of the aircraft were calculated,and the severity of the wake encountered in the aircraft was quantified.The proposed method can be used to reduce the interval operation security risk assessment.
