发动机双发失效空滑策略研究

Research on Dual Engine Failure Gliding Strategy

双发失效是飞机在发动机试飞中可能遇到的最大风险。通过提前规划双发失效后的垂直、水平路径,让飞行机组在遇到双发失效特情时能按照预先规划的路径飞行,遵循最有利的能量使用,减轻机组在特情时的负荷和避免做出不良决策,以期降低双发失效风险带来的影响。

Dual engine failure is the worst hazard of engine flight test. This paper talks about planning of vertical flight path and horizontal flight path. Flight crew will follow the planed path and make full use of energy to lower the workload and avoid bad decision when encountered dual engine failure case.
