Improving hybrid laminar-flow control wing structures with reduced drag
Controlling the flow of air around an aircraft by making that flow laminar can reduce fuel consumption and cut emissions by up to 10 %. In Clean Sky’s Hybrid Laminar Flow Control (HLFC) demonstrator, part of the turbulent airflow around the aircraft is sucked through microperforations on its skin, creating a more stable aerodynamic flow. To reduce HLFC complexity and control suctions, Clean Sky uses variable pitch microperforations along the outer skin of wings. This allows a much easier integration of HLFC systems inside the small space of the leading edge. The EU-funded MICROFORM project will develop a suitable forming process for manufacturing real-scale HLFC wing structures made of thin titanium sheets with variable pitch microperforation. Furthermore, it will conduct simulations to minimise the initial design and manufacturing costs of these large structures.
