Development of laminar wing technologies to reduce the fuel consumption of commercial aircraft.

Commercial air transport is today facing very specific challenges: on the one hand, significant growth forecasts are announced (+4.5% annual growth for the next 20 years) which will result in production increases, and on the other hand, increasingly severe environmental constraints with stricter standards in terms of CO2 emissions, fine particles and noise pollution.

The objective of the LAWITECS project is to develop new wing leading edges for a medium-haul commercial aircraft such as the Airbus A320 in order to make the flow naturally more stable around the profile (NLF) and thus delay the laminar-turbulent transition of the boundary layer. This transition delay will thus have the effect of reducing the friction generated by the aircraft and consequently reduce its fuel consumption by around 5 to 12% (which typically represents a saving of around 1290 kg of fuel on a Brussels – Tel Aviv flight!).

Objectives and missions of Materia Nova

Within the consortium, Materia Nova is developing low-friction, erosion-resistant and easy-to-clean NLF-compatible coatings (roughness Ra < 0.5 μm).
