Abstract

The paper examines the influence on optimal structuraldesigns of changing the finite element selection,the structural design criteria and the designconcepts for an unmanned air-vehicle wing. Thus,single and twin-spar designs are considered with anumber of composite design configurations. Theresults indicate that some of the design criteriahave little influence on the optimal designs whilstfinite element selection can be significant.
