An improved reel take-up system for suppressing the aerial refueling hose whipping phenomenon (HWP) is proposed and analyzed. The conventional spring-loaded take-up system is improved by adding a rewinding acceleration changing rate limiter (RACRL), relying on a permanent magnet synchronous motor (PMSM). The effectiveness of this new reel take-up system is confirmed by the numerical simulation at various closure speeds. The results show that the new PMSM-RACRL reel take-up system successfully accomplishes the active control of tension oscillation and the suppressing of HWP with a straightforward strategy. The amplitude of tension oscillation is reduced to one-tenth of that without active control. It is also discovered that the reel take-up speed lagging behind the drogue closure speed is mainly caused by the oscillation of hose tension, and a maximum acceleration of the reel take-up system lower than the maximum closure acceleration of the drogue will inevitably cause the slack and whipping of the hose.

改进的卷取系统对空中加油软管-锥套动力学的主动控制

提出并分析了一种改进的用于抑制空中加油软管鞭打现象（HWP）的收卷系统。通过增加一个依靠永磁同步电机（PMSM）的收卷加速度变化率限制器（RACRL），改进了传统的弹簧式收线系统。这种新的卷取系统的有效性通过在不同闭合速度下的数值模拟得到证实。结果表明，新型 PMSM-RACRL 卷取系统成功地实现了张力振荡的主动控制和 HWP 的抑制，策略简单。张力振荡幅度减小到没有主动控制的十分之一。还发现卷取速度滞后于锥套闭合速度的主要原因是软管张力的振荡，
