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
雙發及多發直升機單發失效后,直升機飛行所需要的功率由剩餘發動機提供,而在某些需要大功率的飛行狀態時,如起飛狀態、著陸狀態等,剩餘發動機提供的功率可能滿足不了,這就需要對剩餘發動機的可用功率進行合理利用。
