Abstract

Loads and aeroelasticity together influence the aircraft design and thus should be integrated in the early aircraft design. This paper presents the automated loads process, for determining the loads and load conditions, to be integrated in a multidisciplinary design process. The presented loads and sizing process comprises the load case definition, parametric modeling, loads analysis and structural sizing including aeroelastic constraints. The parametric approach set-up aeroelastic models that account for realistic constructions of an aircraft to be used for structural static and dynamic analysis. A case study is presented applied to a wide body aircraft configuration including aeroelastic assessment. The impact of aileron reversal constraint sizing in the loads and sizing process are shown. The identified critical manoeuver and gust loads are presented.
