Abstract: Aircraft
design is a complex large-system engineering
involved in interactions of multidisciplinary and multi-technology fields.
Top-level/detail design technology of
aircraft is an important matter of comprehensive technology adopted by
the modern countries develops advanced aeronautical/astronautical vehicle systems and is
the developing trend of future aircraft design. Based on traditional QFD (Quality function deployment) method, the fuzzy quality function deployment (FQFD)
theory and the step-by-step hierarchy structure in aircraft top decision
are studied. The fuzzy model for computing competitive factor in
evaluation is presented. The greatest characteristic lies in the
proposed hierarchical structure of house of quality for aircraft
top-level design and applying the method of FQFD to aircraft top-level
design. An example, in which the key technologies decision for
improving the performance and affordability of a
fixed-wing aircraft is studied proves the feasibility of the proposed
method. The method has very strong applicability in
aeronautical/astronautical vehicles as aircraft and spacecraft, etc.
Key words: Aircraft
