Aeroacoustic Measurements on the BNF Model

Ahlefeldt, Thomas and Kröber, Stefan and Spehr, Carsten (2013) Aeroacoustic Measurements on the BNF Model. AFDAR Workshop on "Application of advanced flow diagnostics to aeronautics", 06. -07. Feb. 2013, Braunschweig, Germany.

Full text not available from this repository.


In order to alleviate cities and their citizens from aircraft noise, an aircraft model has been designed within the Ger-man research project ‘Bürgernahes Flugzeug (BNF)’ (trans-lated: citizen friendly aeroplane) [1, 2, 3, 4]; it will be opti-mized to enable quiet, efficient, short take-off and landing. This work presents aeroacoustic measurements performed on a BNF half model by means of a microphone array. The focus of the aeroacoustic measurements lies on the noise generated by an active Coanda flow control system used here.
