摘要
本文对涡轮基组合循环发动机(TBCC)中存在的控制问题进行了综合分析。在TBCC运行过程中存在很多过渡段,对这些过渡段的研究非常富有挑战性。TBCC在过渡段的性能,不仅与组成它的涡轮和冲压发动机本身型式及特征有关,还受到两类发动机之间相互关系及调节机构的影响。TBCC控制问题的关键在于保证过渡段稳态和瞬态的性能品质,具体涉及过渡段的燃料、温度控制,进气道和尾喷管喉部调节及阀门开度控制,以及飞行/推进综合问题等。
The control problem in Turbine-Based Combined-Cycle Engine（TBCC） is discussed in this paper.There are many transition phases during the operation of TBCC,which are challenging.The per-formance of the transition phases depend on not only turbine or ramjet engine themselves,but also the relationship of turbine/ramjet engine and the influence of governing mechanism.The key of control prob-lem in TBCC is to guarantee the steady-state and transient-state performance of transition phases,such as the control of fuel and temperature,the regulation of inlet and nozzle throat,the opening of valves,and flight-propulsion integration control at transition phases.
