Testing the High-Lift Common Research Model at the ONERA F1 Wind Tunnel

This paper presents the main features and outcomes of the wind tunnel testing of the High-Lift Common Research Model in the ONERA F1 pressurized low-speed wind tunnel. Two complementary test campaigns were carried out in 2022 and 2023, both using a full-span model, with variations in model configuration, angle of attack, angle of sideslip, Mach number, and Reynolds number, and including force and moment, pressure, wing deformation, and flow visualization data. The main elements of the test methodology are reviewed to better assess the quality of the database in terms of uncertainty, repeatability, and wall and support corrections. A selection of results is presented regarding longitudinal and lateral characteristics, the buildup of the landing configuration, Mach and Reynolds number effects, and flap-setting effects. A special focus is placed on the data that were used in the fifth High-Lift Prediction Workshop.
