In order to meet the design requirements and goals of jet passenger aircraft in various aspects, the overall parameter optimization computing environment was developed. Based on the engineering algorithm, the analysis models of geometry, power, weight, aerodynamics, performance, stability and cost are researched and the corresponding calculation modules are developed. Through the integration of various professional analysis modules, the overall comprehensive analysis model of jetliners is established. Based on the optimization model of the overall parameters of jetliners, the integrated analysis model of jet airliner integrated with iSIGHT platform was established, and the optimization calculation environment of the parameters of jetliners was established. The typical example verifies the feasibility and effectiveness of the optimization of the overall parameters of the jetliner, which provides an effective tool for designers to quickly determine the overall parameters of the jetliner.
