摘　　要：等离子体点火与助燃技术是能源与动力领域的研究前沿。介绍了等离子体点火与助燃技术的研究背景和意义,分析了其基本原理,给出了常见的等离子体点火与助燃的类型,阐述了等离子体通过热强化、动力学强化与输运强化3种强化燃烧机制,利于点火助燃。针对国内外等离子体点火与助燃技术在航空发动机上的研究现状,提出了预燃式等离子体射流点火和旋转滑动弧助燃2种新型等离子体点火助燃方案,对等离子体点火与助燃技术在航空发动机上的实际应用进行了展望。Plasma ignition and assisted combustion technology is the frontier of energy power research field. The research background and significance of plasma ignition and assisted combustion were introduced. The basic principle of plasma ignition and assisted combustion was analyzed. The common type of plasma ignition and assisted combustion are introduced. Then three mechanisms of plasma ignition and assisted combustion are expatiated, which are thermal enhancement, dynamic enhancement and transport enhancement. Moreover, aiming at plasma ignition and assisted combustion using on aero-engine related research at home and abroad, two kinds of new type plasma ignition and assisted combustion solution are put forward. Finally, plasma ignition and assisted combustion application in aero-engine is discussed.
