| Abstract: | 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. |
