摘要
能量角概念已经应用在民航飞机的空速保持和飞机着陆进近阶段产生低能量告警信号等方面.介绍了能量角的定义,利用能量角概念设计的空速保持控制算法的原理,以及利用能量角产生低能量告警信号的方法.作为能量角概念的进化,还形成了基于总能量控制的飞行控制系统.与传统飞控系统相比,基于总能量控制的飞行控制系统具有架构简单、易于移植、飞机速度控制和高度控制耦合小的优势,其应用还有进一步拓展的可能.
Abstract
The concept of energy angle has been utilized for airspeed controlling of civil aircraft and trigging low energy warning signal when aircrafts approach the airports.The definition of energy angle is introduced,and the principle of airspeed control and the method utilizing energy angle to trig low energy warning signal are presented.The flight control system based on Total Energy Control System(TECS) is the evolution of concept of energy angle.Compared with traditional flight control system,TECS based flight control system has the advantages as follows: simpler configuration,convenient emigration,and less couple of speed control and altitude control.It is also possible to broaden the application of energy angle concept to more areas.
