“…The main focus of this atmospheric test has been to gather detailed flowfield information on the vortex dominated interaction of the high-lift wing with engine, pylon, and strake using surface and field measuring techniques such as oil flow, hot films, and three-component particle image velocimetry. A description of the results of the LSWT test is given in [9].…”

“…The present contribution describes results of test campaigns carried out in the ETW in both EUROLIFT projects on four complexity levels of the baseline aircraft configuration. Also being part of EUROLIFT II, selected results of a corresponding campaign in the LSWT of Airbus in Bremen are also included [9]. Special attention is paid to the scaling effects on the different configurations.…”

Within the European High-Lift projects I and II, extensive experimental and numerical investigations on the aerodynamics of high-lift configurations have been carried out. The studies are conducted using the KH3Y windtunnel model DLR F11, which is representative of a wide-body commercial aircraft. A step-by-step complexity increase up to a complete high-lift configuration, including pylon, nacelle, and nacelle strake, is carried out to identify and separate the lift and drag behavior for the components of the high-lift system and their Reynolds number dependency. The wind-tunnel data have been gathered in the European Transonic Wind Tunnel in Cologne in three different test campaigns. To include the complete analysis of the stall behavior for the different configurations of a complex three-dimensional tapered high-lift wing with nacelles extends the scope of a single paper. Therefore, the focus of the present contribution is laid on the detailed analysis of Reynolds number scaling effects with respect to lift curves and drag polars. The combined variation of the dynamic pressure and the total temperature in the European Transonic Wind Tunnel allows covering a Reynolds number range from Re 1:5 10 6 up to deep cryogenic conditions with Re 25 10 6. The final comparison of the four configurations reveals that the sequence of maximum lift values is maintained for the lowest and highest Reynolds number, although the increments between the configurations differ. The strongest increase in maximum lift is observed up to Re 5 10 6. In the intermediate range, 5 10 6 < Re < 15 10 6 , a highly nonlinear behavior of the maximum-lift values is observed, which requires further investigation.

“…Particle image velocimetry represents a suitable tool to provide 3-component velocity information in almost arbitrarily orientated cross-sections of the flowfield. The ability to observe relevant regions of the flowfield for these effects could be successfully demonstrated in the EC-project EUROLIFT II, where 5 sections perpendicular to the model longitudinal axis have been observed 48 . The wind tunnel tests were carried out on the DLR-F11 high lift configuration for low-Reynolds number conditions in the atmospheric wind tunnel of Airbus in Bremen.…”

“…The first one is the low speed wind tunnel of Airbus-Deutschland, B-LSWT. These low Reynolds-number tests under atmospheric conditions have enabled the use of various advanced flowfield measurement techniques like 3-component PIV to provide detailed insight into the dominant flow phenomena 15 . The second involved facility is the European Transonic Windtunnel ETW which is used to address Reynolds-number scaling effects by covering a broad range from low Reynolds-numbers up to flight conditions.…”
