飞行中飞机加油门后的动态特点分析

The Analysis of Dynamic Characteristics in Flight after Advancing the Throttle

主要对飞机单纯加油门后的运动规律做了定量的理论计算，对这一长周期运动进行了一定的分析，得出了飞机在小速度时加油门后有三种可能的状态，即收敛、发散和中立稳定。并指出飞机加油门后的增速状态是暂时的，一般情况下增速之后，是一个高度与速度相互转化的振荡过程。同时还指出低空小速度时，在加油门后暂时的增速过程中靠拉杆争取高度是不安全的。

In this article, the author made quantitative calculation on the law of plane's motion. These analyses show, in the condition of low flying speed, three possible states of convergence, divergence and neutral stability may be engendered after merely advancing the throttle. As the result of this operation, a posture of acceleration is transient. That follows an oscillating transition process of altitude and velocity. In this process, it is not safe to pull back for a higher altitude.
