Systems driven HLFC design

Atkin, C.J. & Backer Dirks, T. (2015). Systems driven HLFC design. Paper presented at the 50th 3AF International Conference on Applied Aerodynamics, 30 Mar - 01 Apr 2015, Toulouse, France.


The paper presents an aerodynamic study carried out in parallel with the EU AFLoNext project to assess the issues involved in combining hybrid laminar flow control (HLFC) technology for drag reduction with wing ice protection systems (WIPS). The paper describes the selection of appropriate test cases in the literature which are representative of wings designed for HLFC system and the progression from an initial baseline HLFC chamber layout to layouts driven by practical constraints such as WIPS requirements and aircraft structure. The resulting HLFC system is a compromise between all concerned systems. Conclusions are drawn about design driven not purely by performance but by the ability to physically implement the system on a commercial aircraft.
