摘要:

受吴仲华先生“叶轮机械三元流动理论”的启发，在前期压气机等离子体流动控制研究的基础上，进一步提出等离子体激励式压气机的概念，即将等离子体激励融入到S1，S2流面压气机气动设计之中，以释放常规压气机设计中失速裕度、负荷极限等因素的约束。本文旨在探讨等离子体流动控制在新一代高负荷压气机中应用的前景和研究趋势，通过原理论证与实例分析，首先阐述了等离子体激励式压气机的概念，然后梳理了压气机等离子体流动控制研究的若干进展，以论述等离子体激励式压气机设计的研究基础，最后给出了等离子体激励式压气机的典型技术路径和理论基础。

Abstract:

Inspired by the “Theory of Three-Dimensional Flow in Turbomachines” of Dr Wu Chung-Hua， and based on the previous researches on plasma flow control of compressors， the notion of plasma actuated compressor， which intends to combine the plasma actuation with the compressor aerodynamic design in S1/S2 stream surfaces， is proposed to release the restriction of stall margin and loading limit in traditional compressor aerodynamic design. This paper aims at discussing the prospects and research trends of the applications of plasma flow control in modern highly-loaded compressors. Through theoretical argumentations and case studies， the notion of plasma actuated compressor is introduced firstly， and then to discourse the research basis for the design of plasma actuated compressor， some research progress on the plasma flow control of compressor by the authors are listed. The results provide the typical technological routes and theoretical basis of the plasma actuated compressor.
