The feasibility of laminar flow control technology for future wing is bound to the development of a leading edge high-lift system that complies with the requirements on smooth surfaces to enable maintaining the laminar boundary layer flow. Classical leading edge high-lift devices like slats are not suitable as they introduce disturbances in the very sensitive upper surface leading edge area. Within the European AFLoNext (Active Flow, Loads & Noise Control on Next Generation Wing) project, a full scale HLFC leading edge demonstrator was designed and built that incorporated the vented foldable bull nose Krueger. In summer 2018 this demonstrator was wind tunnel tested in the CIRA Icing Wind Tunnel facility. Within this test the aerodynamic design was verified. Additionally, it was tested whether the Krueger device would need a distinct de-icing system. The contribution summarizes the design of the Kruger device together with the findings from the full-scale wind tunnel test of the Krueger flap configuration.
