摘　　要：在总结国外关于丝电弧等离子体强化超声速点火和燃烧现状的基础上,分析了丝电弧等离子体强化超声速点火和燃烧的特点.基于等离子体点火强化超声速燃烧的基本原理,设计了4种丝电弧等离子体强化超声速点火和燃烧的电极布置方案,凹槽式燃烧室强化燃烧方案、平板式单排纵向放电强化燃烧方案、平板式双排横向放电强化燃烧方案和平板式多排纵向放电强化燃烧方案.对每种方案的优缺点进行了分析;设计了丝电弧等离子体强化超声速点火和燃烧的放电特性试验系统,并进行了初步的放电试验.Based on the analysis of research status of thread arc plasma assisted supersonic ignition and combustion, the characteristics of thread arc plasma assisted supersonic ignition and combustion were ana- lyzed. Based on the basic principles of plasma assisted ignition and combustion, four arrangement schemes of thread arc plasma assisted supersonic ignition and combustion were designed. The four schemes were recessed as- sisted combustion, flatbed single row vertical discharge assisted combustion, flatbed double transverse discharge assisted combustion, and flatbed multi-row vertical discharge assisted combustion. The advantages and disadvantages of each scheme were analyzed. The test system for the discharge characteristics of thread arc plasma assisted super- sonic ignition and combustion was designed, and a preliminary discharge experiment was conducted. At last, some discharge experiments were performed.
