本文简要介绍了“智能”发动机部件的概念，并讨论了目前处于研究阶段的这一概念的各种应用。然后通过回顾燃气轮机压缩系统旋转失速和喘振气动不稳定性的动态控制来说明智能发动机研究的跨学科性质。已经证明，这些不稳定性可以通过主动反馈控制来稳定。基于这项研究，基本的跨学科问题得到了发展，包括非定常流体力学的识别，选择合适的信号和波发射器来实现反馈，以及实现发动机部件的实际控制技术。
This article briefly describes the concept of “smart” engine components and discusses various applications of this concept that are currently in the research phase. The interdisciplinary nature of smart engine research is then illustrated through a review of dynamic control of aerodynamic instabilities in gas turbine compression systems rotating stall and surge. It has been demonstrated that these instabilities can be stabilized by active feedback control. Basic interdisciplinary questions have evolved based on this research, including identification of unsteady fluid mechanics, choosing suitable signals and wave launchers for implementing feedback, and enabling technologies for real-world control of engine components.
