Aerodynamic Noise and the Estimation of Noise in Aircraft
The Journal of the Acoustical Society of America, 1952Noise resulting from the flow of air over the fuselage of an airplane has been investigated and found to depend principally on approximately the fifth power of the indicated air speed. The resulting emperical relation of noise level to airspeed is found to be quite useful in estimating the noise in the frequency range above 600 cps, for airplanes ...

Journal of Fluid Mechanics, 1971
A symposium on aerodynamic noise was held at Loughborough University from 14 to 17 September 1970 under the sponsorship of the Royal Aeronautical Society and the British Acoustical Society. The objective of the meeting was to focus attention on unsolved theoretical and experimental problems which will require attention over the next few years.

Aerodynamics and Noise of Coaxial Jets
AIAA Journal, 1977The objective of this investigation was to develop a unified prediction method for estimating the aerodynamic and noise characteristics of jets issuing from nozzles of arbitrary geometric shapes. The method has been developed and demonstrated for dual-flow coaxial jets.

On the scattering of aerodynamic noise
Journal of Fluid Mechanics, 1971According to the Lighthill acoustic analogy, the sound induced by a region of turbulence is the same as that due to an equivalent distribution of quadrupole sources within the fluid. It is known that the presence of scattering bodies situated near such multipoles can convert some of their intense near field energy into the form of sound waves whose ...

On Noise of Aerodynamic Origin
The Journal of the Acoustical Society of America, 1953An attempt is made in this paper to classify noises of various aerodynamic origin by means of an efficiency of conversion from mechanical to acoustical energy, and also by means of representative spectra associated with corresponding characteristic frequencies.

The heading aerodynamic noise includes all cases where sound is generated by fluid flows. It includes aeolian harps, edge tones and related phenomena as well as vortex, boundary layer, wake and jet noise. In the strict sense it does not include propeller noise and the direct noise generated by; bodies in motion.
