  • An integrated performance computing model for aircraft/engines was studied,and a visual software based on the model was further developed.The model consisted of engine's uninstalled performance computing model,inlet and nozzle/aftbody performance characteristic transferring model,engine's installed performance computing model and flight performance computing model.Using inlet and nozzle installation methods(INSTAL),the installed engine performance was calculated in conjunction with uninstalled engine performance and installed performance characteristics of the inlet and nozzle/aftbody which had been obtained through inlet and nozzle/aftbody installation transferring program.Based on above study,the aircraft performance was calculated as well.The software was applied to estimate integrated performance of a certain aircraft.The results show: (1) comparing with the empirical formula method, the degree of closeness between the estimation of installed engine performance using INSTAL and the data from designer is increased in general, and it can be increased by 13% in maximum; (2) the calculating results are reasonable with short executing time and high accuracy.
