Abstract

Natural Laminar Flow (NLF) airfoils are shaped in such a way to delay as much as possible laminar to turbulent flow transitions in cruise in order to decrease viscous drag. NLF airfoils have better performance, lowering the fuel consumption and reducing carbon dioxide (CO2) emissions. The technological improvements of this topic are inspired through Hybrid Laminar Flow Control (HLFC) technology, under Clean Sky 2 platform. This will strengthen innovative advances in the next generation of aircrafts; overcoming the risks and the technologies eventually to join the next market window to replace the present fleet.The main objective described in this presentation is to simulate the manufacturing process of commercial aircraft leading edge by RTM and obtain reliable results of residual stresses and final distortions. This project has received funding from the Clean Sky 2 Joint Undertaking (JU) under grant agreement No 807097.
