The Simulation of Aircraft Gas Turbine with Dymola Modelica
Guang Meng · Thermal Turbine · 2004
According to modular modeling means, the gas turbine is divided into two parts: the flow model and the volume model. The flow (model) is the res1ult of a modeling abstraction, where the volume is neglected. The volume model mainly indicates duct connecting. It can be thought that storages of the mass and the energy are modeled in the control volume, whereas the flows of the mass and the energy are modeled in the flow model. In order to get simulation models, the Dymola Modelica is introduced to program models and the Modelica is an object-oriented and non-casual language for modeling of the larger, multi-domain system. In the paper, the aircraft gas turbine models are programmed and the extensible gas turbine libraries are constructed based on the Dymola Modelica. On the basis of gas turbine models and other models, a double tools turbofan engine with switch reluctance generator model is constructed. The rational simulating results are obtained and the method is verified to be reasonable. The developed simulation tools based on the Dymola Modelica can be used in other power systems
