On the generation of side-edge flap noise
TL;DR: In this paper, a theory for estimating the noise generated at the side edges of part span trailing edge flaps in terms of pressure fluctuations measured just inboard of the side edge of the upper surface of the flap was proposed.
Proceedings ArticleDOI
Aircraft Flap Side Edge Noise Modeling and Prediction
TL;DR: In this article, a model for aircraft flap side edge noise prediction is presented, which is based on the theory of aerodynamic sound generation, relating the noise spectrum to the surface pressure statistics on the surfaces of the flaps in the vicinity of the side edges, the characteristic length and time scales in the flow, and the Greens function that accounts for sound-flow coupling and propagation/scattering effects.
Dissertation
Caractérisation des sources de bruit aérodynamique à basses fréquences de dispositifs hypersustentateurs
TL;DR: In this article, the authors present an experimental analysis of a maquette d'aile bidimensionnelle, a ete menee sur a 1/11eme, representative of a section de voilure reelle, composed of a bec de bord d'attaque and a volet of bord de fuite simple.
Proceedings ArticleDOI
Development of an empirical prediction model for flap side-edge noise
TL;DR: In this article, a series of aero-acoustic tests were performed to investigate the characteristics of the flap tip cross-flow velocity and side-edge noise in low-noise aircraft.
Proceedings ArticleDOI
Local dynamics and acoustics in a simple 2D model of airfoil lateral-edge noise
TL;DR: In this article, a model of the edge vorticity was proposed, in which the time-averaged edge vortex was represented by a single line vortex perpendicular to the plane of the flow and the potential flow was idealized by potential flow around a square comer.
