TY  - JOUR
AB  - This paper investigates geometrically-nonlinear aeroelastic effects on an industry-level aircraft configuration. Results are obtained via a new approach that uses geometrical informationto compute nonlinear effects and seamlessly integrates with conventional, linear aeroelasticload packages. The starting point is a generic finite-element model and frequency-domainaerodynamic influence coefficient matrices, and the resulting system includes control inputs,longitudinal trim, or gust disturbances in time domain, which can be employed separately orin combination to obtain a nonlinear dynamic model for loads and stability analysis. Theaeroelastic response of a long range aircraft is studied, highlighting the difference betweenlinear and nonlinear approaches in the calculations of the aircraft flying equilibrium, dynamicperturbations, and variations to the flutter boundary. Results justify the need for geometrically nonlinear analysis in the production environment of airplanes with ultra high aspect ratiowings.
