At a ceremony in Washington DC, Airbus’ BLADE demonstrator program received the prestigious 2018 Aviation Week Laureates Award for Commercial, Technology. The panel of judges recognized the team for bringing to fruition the most extensive wing laminar flow demonstrator program ever undertaken for commercial aviation. The BLADE project – which stands for “Breakthrough Laminar Aircraft Demonstrator in Europe” – is part of the EU-sponsored Clean Sky program and is tasked with assessing the feasibility of introducing laminar flow wing technology on a large airliner. It aims to improve aviation’s ecological footprint, bringing with it a 50% reduction of wing friction and up to five percent lower CO2 emissions.
Axel Flaig, SVP of Research and Technology at Airbus said: “We are extremely honored to receive Aviation Week’s Laureates award for Technology. I am also proud of what our BLADE teams in Airbus and in our partner companies in Clean Sky have achieved. Together we continue to lead the way for the efficient future of commercial aviation.”
In September 2017 Airbus’ A340 laminar-flow “BLADE” test demonstrator aircraft (A340-300 MSN001) made its successful maiden flight and since then has been engaged in successful testing to explore the wing’s characteristics in flight. The aircraft, dubbed ‘Flight Lab’, is the first test aircraft in the world to combine a transonic laminar wing profile with a true internal primary structure.
On the outside the aircraft is fitted with two representative transonic laminar outer-wings, while inside the cabin there is a highly complex specialist flight-test-instrumentation (FTI) station. The extensive modifications to the A340-300 test-bed aircraft took place during the course of a 16-month working party in Tarbes, France, with the support of numerous industrial partners across Europe. In terms of the testing technology, notable ‘firsts’ included the use of infrared cameras to monitor the laminar flow transition points and the acoustic generator which measures the influence of acoustics on laminarity. Another first is the innovative reflectometry system which measures overall deformation in real-time during flight. To date the Flight Lab has performed 66 flight hours.
