Design and experiment of gaseous hydrogen/oxygen engine igniting with electric spark igniting in vacuum

  • 摘要: 为研究某大推力氢氧发动机真空羽流效应,设计采用火炬点火方式的60N缩比氢氧发动机.通过球头密封声速喷嘴组件控制流量,使真空下每个声速喷嘴组件减少3个密封面.进行真空点火方案设计,从理论上证明电火花点火的可行性.设计试验系统并进行地面及真空环境下的热试车,试车结果表明:燃烧室压力达到额定压力为0.6MPa时,发动机热防护结构良好,试验系统设计合理,真空电火花点火方案可行,为进行真空羽流效应研究奠定基础.
