Development of a Fast Conceptual Parameter Analysis Tool for Passenger Aircraft

In order to apply computers to airliner conceptual design, an engineering method based airliner conceptual multi-parameters synthesis analysis platform is developed, namely CTAP (Civil Transport Analysis Platform). Modules including propulsion, stability&control and landing gear were developed; several modules including geometry, aerodynamics, performance and weight were updated; a new function was added which can proceed conceptual parameters sensitivity analysis based on surrogate model; engine database was built; content and format of input as well as output was re-organized; a new function was added which can display 3D configuration of airliner; a series of user interface was developed.
