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。 It mainly makes a quantitative theoretical calculation of the movement law of the airplane after simply filling the throttle and analyzes the long-period movement to some extent. It is concluded that there are three possible states of the aircraft when the throttle is operated at a small speed: convergence, divergence Neutral and stable. And pointed out that the growth rate of aircraft after the accelerator is temporary, under normal circumstances after the growth rate is a high degree of mutual transformation of speed and oscillation process. At the same time also pointed out that when the low-altitude small speed, the fuel tanker in the temporary growth rate by rod for height is not safe.
