Abstract

The efficiency of the structure of a civil aircraft may be gauged by the financial performance of the aircraft over its life span. In this thesis a method of structural design is proposed with the object of maximising the life-cycle profit for the airline operating the aircraft. In the formulation of the design process. original contributions have been made in various aspects of optimal cost design theory. The design process is applied to the optimisation of a specimen structure, which is representative of an idealised aircraft wing. The results of the analysis are of importance, since they indicate the manner in which the optimal configuration of a practical structure will vary with the individual characteristics of the aircraft design in which the structure is to be incorporated. The degree to which the optimisation process is degraded by those errors encountered in a practical environment is ascertained by means of sensitivity analyses.
