## Analysis on stability and structure computation of helicopter with slung-load

• 摘要: 针对特定的直升机吊挂载荷飞行任务,给出了吊挂几何构型的计算方法,计算了吊挂的几何参数和绳索内力,并在此基础上分析了飞行速度和吊挂重量对几何构型的影响.针对特定的飞行任务,考虑吊挂的几何尺寸和详细构型,在已有模型的基础上进行了改进和配平计算,配平结果与以前的结论吻合得很好,证明模型可用.计算并分析了不同速度、吊挂参数下系统的平衡和稳定特性.结果表明:带吊挂飞行的直升机,速度增加可以改善横向的螺旋不稳定,但对纵横向的周期模态都会产生不利影响.
