Abstract: An integrated design parameter selection method and software for the airplane/engines with high maneuverability were developed. Determining design merits and constraints including flight performance constraints and engine component design constraints on the basis of the mission requirements for fighter, the integrated selection and optimization of airplane/engine design Parameters were conducted. The software consists of airplane geometry and weight, airplane aerodynamics, engine uninstalled and installed performance, engine weight and overall dimension, flight performance and optimization modules.The software has been applied to the concept demonstration for the existing airplane/engine modification, analysis and study of the integrated design for future airplane/engines with high maneuverability. borne examples are presented. It is shown with experience that the calculating results were reasonable, accuracy and the executing time were suitable to concept demonstration and preliminary design for airplane/engine system.
