  • 摘要:

    针对单发、全发失效(OEI/AEI)后提升倾转旋翼机安全性的需求,基于最小化回避区思想分析预测倾转旋翼机的高度-速度低速回避区。首先,引入混合操纵模型,建立倾转旋翼机发动机失效后增广的二维纵向刚体飞行动力学模型,基于最优控制理论将倾转旋翼机低速回避区边界转化为安全着陆问题;然后,构建倾转旋翼机发动机失效后安全着陆飞行的连续非线性最优控制模型,采用间断有限元法(DPG)和非线性规划算法进行求解;最后,以XV-15为研究对象,验证了算法的准确性,并研究了不同飞行重量、操纵要求下,倾转旋翼机的单发、全发失效的高度-速度低速回避区,分析了倾转短舱对低速回避区的影响,给出了XV-15单发失效的垂直起飞最大安全重量。
