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

The fourteenth AerospaceLab Journal issue 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.
