摘　　要：为研究自由涡轮式涡轴发动机的稳态特性,建立了基于部件法的涡轴发动机稳态特性计算模型,编制了计算程序,并指出了涡轴发动机各部件在共同工作时需要满足的平衡关系,同时建立了求解稳态特性计算模型的非线性方程组。然后利用编制的稳态特性计算程序,计算了某涡轴发动机在考虑使用限制时的最大状态特性和不同高度下的节流特性。通过对计算结果对比分析,研究结果表明:建立的计算模型是合理的,可作为深入研究自由涡轮式涡轴发动机稳态特性的工具,具有一定的工程应用价值。For studying the steady-characteristics of turbo-shaft engine with free turbine, based on component modeling, its mathematical model is built in this paper, and the corresponding program is developed. The balance that all components work in together need to fulfill is indicated. At the same time, the non-linear equations are built. Using the corresponding program, the maximal-state characteristics and throttle characteristics of certain turbo-shaft engine at different altitudes are computed. After analyzing the computing results, it shows that the computing model built in this paper is reasonable. It can be treated as a good tool to study the steady-characteristics of turbo-shaft engine, so there is a splendid applied-value.
