Aerodynamic design of a folded kruger device for a hlfc wing

Abstract

This work presents the design of a folded Krüger device under realistic geometrical requirements for a wing with hybrid laminar flow control (HLFC). A focus is laid on the investigation of the trade-off between space allocation of the retracted Krüger and the aerodynamic high-lift performance. The results reveal that the Krüger device is able to replace a reference slat device in relation to its aerodynamic high-lift performance. Further on the reduction of the allocation space influences the high-lift performance unfavorably.
