Comparison of the Results of Tests on A300 Aircraft in the RAE 5 Metre and the ONERA F1 Wind Tunnels.

Abstract

Studies of the A300 Airbus aircraft have been carried out in the pressurized low-speed wind tunnels at RAE and ONERA. Initially comparison of the results obtained in the two facilities, with the same model mounted on an identical three-strut support, showed discrepancies which in the case of lift coefficient amounted to about 2.5%. A detailed comparison of all of the procedures used in processing the measurements led to a series of modifications in data reduction techniques in the two facilities. When these modifications are all taken into account, the results on lift and drag on the A300 which have been provided by the two tunnels now show good agreement confirming the accuracy of the measurement techniques and the broad framework of the corrections. Keywords: Aerodynamic lift; Aerodynamic drag; Aerodynamic characteristics. (sdw)
