| Abstract: | A rapid and simple mathematical model for turbines, which is based on the characteristic equations and is able to attain design precision, has been developed. The computer language Modelica and the editor Dymola were used for programming the models and also for simulating turbine performance. By a model simulation of an engine on system's level the effectiveness of the turbine model was verified. Results manifest that the formulated mathematical model can properly simulate turbine performance even in off-design modes of operation and at reduced flow. The composed turbine stage modules are distinguished by their typicality their independence, generality and link-up ability. They can meet the requirement for rapidly establishing dynamic models of aircraft power systems. Figs6 and refs 6 |
