Aeroelasticity in regard to aircraft structures is defined as the branch that investigates the phenomena that emerge due to the interaction of aerodynamic (in particular unsteady), inertial, and elastic forces emerging during the relative movement of a fluid (air) and a flexible body (aircraft). Aeroelastic phenomena may be divided according to ...

Abstract. Aeroacoustics is concerned with sound, generated by turbulent fluid motion or aerodynamic forces interacting with surfaces. Although no complete scientific theory of the generation of noise by aerodynamic flows has been established, most practical aeroacoustic analysis relies upon the socalled Acoustic Analogy, whereby the ...

Aeroacoustics is a branch of acoustics that studies noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces. Noise generation can also be associated with periodically varying flows. A notable example of this phenomenon is the Aeolian tones produced by wind blowing over fixed objects..
