This paper studies optimal helicopter flight operations in the event one-engine failure. A three-dimensional point mass with a yawing motion of UH-60A has been used to study RTO and CTO from an elevated heliport or from a heliport, A first order dynamic of the OEI contingency power is considered. Flight after engine failure are formulated as nonlinear optimal control problems.

双发及多发直升机单发失效后，直升机飞行所需要的功率由剩余发动机提供，而在某些需要大功率的飞行状态时，如起飞状态、着陆状态等，剩余发动机提供的功率可能满足不了，这就需要对剩余发动机的可用功率进行合理利用。

In the condition of definitive structural parameter and part of operative parameter of impulse engine, the effect of controlling force of impulse engine on correct trajectory is analysed. The number of total layer, impulse of each impulse engine and fire interval are determined when the correct ability and flight stability are satisfiable.
