STATIC AEROELASTIC TRANSONIC ROLLING CAPABILITY OF A MODERN FLEXIBILITY WING

Resumo

© Proceedings of the International Forum of Aeroelasticity and Structural Dynamics 2022, IFASD 2022.This paper presents a static aeroelastic investigation of the rolling capability of a modern flexible wing with the objective of flight test campaign clearance. A conventional configuration transport aircraft was evaluated in transonic conditions between Mach 0.82 and 0.89. A fluid-structure interaction tool with aileron deflection was considered to simulate the wing flight deformed shape effect on rolling capability, also with the undeformed fluid dynamics simulation reference for comparison. The applied code E2-FSI, which couples Reynolds Average Navier Stokes (RANS) fluid dynamics and static structural analysis, was improved to consider the different positions of control surface. The numerical results were compared to wind tunnel test data, with and without linearized aeroelastic corrections. The comparison in terms of rolling coefficient and flow topology are presented. The improve in the method fidelity resulted in advanced understanding of extreme rolling condition.
