摘　　要：分析了在等离子助燃条件下,燃烧室进口前等离子体复合的机理,计算和分析了复合度、平衡常数随等离子体温度、压力和密度的变化。计算结果表明:在等离子助燃条件下离子复合可使燃烧室进口的初温升高,离子密度下降,从而对燃烧室助燃产生有利和不利的影响,这就需要从总体上考虑,通过调节温度、压力、离子浓度等达到燃烧室最佳燃烧效果。This article analyzes the mechanism of plasma compound before engine combustor with plasma assisted combustion, and calculates compound degree and equilibrium constant with plasma temperature, pressure and density variety. The results show that, with plasma assisted combustion, ions compound would make temperature hoist and density decline, and make good and bad effects on engine combustor assisted combustion, which should take these factors into account totally, Finally, the combustor will achieve the best effect of combustor assisted combustion through adjusting the temperature, pressure and density of plasma.
