摘　　要：研究了非平衡等离子体助燃的机理,并用最小Gibbs自由能理论对注入粒子后甲烷的燃烧进行了计算。对注入不同量粒子后燃烧温度和燃烧产物的分析证明,等离子体所具有的化学动力学特性可以加快反应的进行,增加燃烧温度和降低燃烧污染物的排出,从而验证了等离子体在航空发动机燃烧室中助燃的可行性。The mechanism of non - thermal equilibrium plasma assisted combustion is recommended. In this paper the assisted combustion effect of methane is calculated by using the Gibbs free energy theory. Based on the analysis of the burning temperature and the combustion products after the injection of various quantity particles, the chemical kinetic characteristic of plasma can expedite the process of reaction, increase the burning temperature and re- duce the ejection of the pollutant, which verifies that the use of plasma to assist combustion in aero engine combustion chamber is feasible.
