Development and simulation a forming process adequate for manufacturing microperforated outer skin for leading edges of HLFC wings with double curvature and variable micro-perforation density. Stretching and hot forming will be developed and compared with small-scale demonstrators, in order to define the more adequate technology for manufacturing of final demonstrators. Preliminary studies could consider also other alternative forming technologies proposed by partners. Chosen forming method will be simulated and validated with several large-scale demonstrators up to 5 meter long. Please refer to the full topic descriptions document published in this call.
