A particularly investigation is carried out to the observibility of in-flight alignment using numerical simulation when the aircraft performs four kinds of basic maneuvre, namely linear acceleration, yawing, pitching and rolling. The thesis summarizes the two kinds of maneuvre. Simulation results show that the precision of transform alignment reach 5 minutes in 10 seconds if the aircraft performs two well-defined maneuvres.

首先本文采用数值分析的方法研究了直线运动、航向角运动、俯仰角运动和横滚角运动对传递对准系统可观性的影响规律；再结合飞机的实际运动，给出了空空导弹传递对准时的飞机飞行轨迹；"蛇形"飞行轨迹和摇摆运动飞行轨迹，仿真结果表明：按这两条飞行轨迹机动，在10s内传递对准精度可达到5′以下。

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.
