An experimental study of the noise of flow past a wing at low velocities
Abstract
The effect of the incoming flow velocity and turbulence on the spectrum and radiation pattern of wing noise is investigated experimentally. It is found that the incoming flow spectrum has only a slight effect on the continuous component of the wing noise spectrum. Various methods of modifying the tonal noise components and their characteristics are discussed.
