摘　　要：为了突破传统空中加油稳定伞对于加油机飞行速度和高度的限制,设计了一种加装气动弹性支架的可变阻尼稳定伞。通过流固耦合(FSI)数值模拟,得到不同工况下的片状弹簧变形与稳定伞伞面形状,通过计算流体动力学(CFD)得到稳定伞气动力的变化趋势。根据气动力结果计算软管的拖拽形状及锥套下沉量。仿真结果表明:所设计的可变阻尼稳定伞的阻力变化量和锥套在空中位置变化范围分别降至传统稳定伞的70%和60%,能够实现阻力的自适应控制,拓宽了传统结构稳定伞适用的速度、高度范围。To break through the restrictions imposed by traditional paradrogue on the speed and altitude of the tanker aircraft, a variable damping paradrogue with aero-elastic structs was designed. The flaky spring deformation and canopy configurations were obtained by fluid-structure interaction(FSI) analysis, and the trend of paradrogue drag was investigated by computational fluid dynamics(CFD). The hose configuration and the paradrogue draught position were simulated. Results demonstrated that the magnitude of the drag and draught position variation of this design was reduced to 70% and 60% of the traditional type respectively. This design can generate self-adaptive drag, and limit the paradrogue movement, so it is applicable at a broader range of speed and altitude.
