在起飞、爬升、巡航、下滑着陆和其它飞行过程中,发动机油门位置要根据不同飞行情况加以改变。对一个给定的飞行任务,发动机油门位置的变化方式可以有一个最有利的组合以使一架给定的飞机的飞行性能最佳。这一最有利的组合即称之为发动机最佳工作方案。本文给出了一种快速的发动机最佳工作方案的优选方法。 作为一例,我们将这里提供的方法用于优选高空无人驾驶侦察机的最大航程。用本方法的计算结果表明,和发动机工作方案选择不当的情况相比,航程可以增加(6～9)％本文还讨论了大气温度改变和发动机转速调节精度对最佳工作方案的影响。
During take-off, climb, cruise, landing, and other flights, engine throttle positions vary depending on the flight. For a given mission, the engine throttle position can be varied in the most advantageous combination to maximize the flight performance of a given aircraft. This most advantageous combination is called the best engine work plan. This paper presents a quick and optimal method of engine optimization. As an example, we will use the method provided here to optimize the maximum voyages of an altitude unmanned reconnaissance aircraft. The calculation results of this method show that the range can be increased by 6 ~ 9% compared with the improper selection of engine work program. The paper also discusses the influence of the change of air temperature and the accuracy of engine speed regulation on the optimal work plan.
