Aeroservoelasticity (LARCASE)

Several large-scale projects were carried out at the LARCASE at ÉTS in numerical studies and experimental tests for morphing aircraft using three equipments. In this article, these projects are explained. First, two projects have been carried out at LARCASE on morphing wing studies in collaboration with industrial and research institutes teams.

The determination of loads acting on the aircraft is one of the main tasks during aircraft development. The knowledge of loads is important for aircraft design, e.g., for the sizing of the airframe structure, as well as for certification. The definition of realistic load assumptions is important, as well as the generation of loads from simulation and experiment.

Aeroelasticity and Structural Dynamics

Cédric Liauzun, Nicolas Piet-Lahanier (ONERA)

The fourteenth issue of AerospaceLab Journal is dedicated to aeroelasticity and structural dynamics. Aeroelasticity can be briefly defined as the study of the low frequency dynamic behavior of a structure (aircraft, turbomachine, helicopter rotor, etc.) in an aerodynamic flow. It focuses on the interactions between, on the one hand, the static or vibrational deformations of the structure and, on the other hand, the modifications or fluctuations of the aerodynamic flow field.
