Abstract:

In order to improve the quality and efficiency of civil aircraft conceptual/preliminary design, the implementation of fuselage section and cabin design in a computer aided aircraft conceptual/preliminary design system is studied. The coordinates of  fuselage like components are defined. The parametric modes of section, cabin floor, furnishment, cookroom, washroom, cloakroom, emergency exit, port, dummy plate, seat and baggage rack are presented. The data structure and defining logic representing the cabin and section are designed.A prototype system for the fuselage section and cabin design is constructed. Automatic adjustment for the cabin is implemented, which is the basis for multidisciplinary design optimization that takes into account such factors as weight, aerodynamics and structure. Finally, several instances are given to illustrate that the methods of cabin design and automated adjustment are effective.
