Aerothermodynamic Simulation Calculation of a Certain Turboprop Engine
摘要
Abstract
In order to study the aerothermodynamic process of a certain turboprop engine, the value of aerothermodynamic parameters and overall performance parameters between each component in gas path was calculated and the relationship between them was analyzed to provide a theoretical basis for engine design. Aerothermodynamic calculation study is per⁃formed focusing on the gas path structure of a certain turboprop engine, the main operating parameter data of engine design point given by design manual were used to do aerothermodynamic calculation, comparing the value of calculated overall en⁃gine performance parameters with the value of overall performance parameters given by design point to verify the effective⁃ness and accuracy of the simulation algorithm. Focusing on the error generated by the results of aerothermodynamic calcu⁃lation, the coupling coefficient of component characteristics and the impact on engine performance of air entraining and other factors, which were needed to consider for algorithm optimization, were preliminary analyzed and verified.关键词
