Design And Evaluation Of A High-Speed Aeroacoustic Wind Tunnel

 During cruise flight, the main source of acoustic noise radiation

within the aircraft cabin occurs as a result of structural

vibrations of the flexible fuselage panels due to the random

pressure fluctuation field imposed by the Turbulent Boundary

Layer (TBL) [1]. Conventional methods of describing these

interactions have relied on the use of various statistical semiempirical

models which predict the behavior of the TBL pressure

fluctuation spectrum. Each model however makes fairly

different predictions with regards to the spectrum in the various

frequency regions. There is therefore a need to not only

assess these inconsistencies with experimental methods, but

also to clarify the fundamental physical relationship between

the turbulent structures and the resulting fluctuation signature.

The present phase of this research initiative at Carleton University

involves the design and fabrication of the new High-

Speed Aeroacoustic Wind Tunnel (HSAWT), which is capable

of studying wall pressure fluctuation behavior at subsonic

flow speeds up to typical cruise flight conditions.
