| 摘 要： | 建立了直升机单发失效后增广的纵向三维刚体飞行动力学模型,通过选择合适的目标函数、路径约束和边界约束,将自转着陆问题表示成非线性最优控制问题,使用非线性规划方法求解得到自转着陆的最优轨迹和操纵.以UH-60直升机为例,首先计算了自转着陆距离最短的最优解,并与二维点质量模型进行对比.结果表明三维刚体模型在旋翼转速、旋翼拉力...

| Abstract: | This paper studies the trajectory optimization of helicopter autorotation landing in the event of one engine failure by applying the nonlinear optimal control theory.An augmented longitudinal three-dimensional rigid-body flight dynamic model of a helicopter is first presented.By selecting the appropriate objective function,path constraints and boundary constraints,the trajectory optimization problem of helicopter autorotation landing is then formulated into a nonlinear optimal control problem,which is furth... |
