Design Concepts for Stabiliser Leading Edges with HLFC Technology and Bird Strike Resilience

Kurzfassung

Laminar technology provides tools to reduce the specific fuel burn of aircraft. Promising results give the hybrid laminar flow control (HLFC) technology. Together with efficient flying, bird strike tolerance is mandatory for safety reasons. The current work considers HLFC in horizontal stabiliser leading edges with a multi-chambered structure. The bird strike simulation accompanied manufacturing and engineering studies. The developed design was confirmed by testing of a demonstrator. Based on the results validation methods were used to improve the modelling & simulation. The work has received funding from the Clean Sky 2 Joint Undertaking (JU) under grant agreement No 945583 (ECHO, HLFC-WIN). The JU receives support from the European Union's Horizon 2020 research and innovation programme and the Clean Sky 2 JU members other than the Union. Furthermore, the work has received institutional funding of DLR under the aeronautical research programme.
