Seats number and design range,as direct reflection of marketing orientation,are the key parameters of a civil aircraft.The current global large airliner market is dominated by Boeing and Airbus,including narrow body aircraft,wide body aircraft and super large aircraft,among which the wide body aircrafts have a large scope of design range,Both Airbus and Boeing have settled the new generation of wide body aircraft as the remote type.However,the controversy of the development of medium and short range wide body aircraft has never stopped.As Airbus has launched the A330Reginal project,the profit of medium and short range wide body aircraft becomes hot debate.In view of this,large airliner with certain seats level is selected in this paper to analyze the combined impact of design range on wing,engine,aerodynamic performance,characteristic weights,fuel efficiency and the operating cost,the influence of design range on civil aircraft overall design is also illuminated.Finally the benefit and losses due to design range variation are concluded in the technical prospective.
Key words： airliner; civil aircraft; design range; overall design; synthesis optimization; parametric
