An optimal cost approach to aircraft structural design

Moden, D

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.
