The 7th European Union (EU) Research and Development (R&D) framework programme included Clean Sky Joint Undertaking (JU) as a public-private initiative. The Clean Sky goal was to develop new technologies to achieve more environmentally friendly aircraft, carrying out all the steps to reduce the environmental impact of commercial transport aircraft. This was translated into integrating, demonstrating, and validating technologies capable of reducing CO2, NOx and noise emissions between 20 to 30% compared to the benchmark aircraft of 2010. Clean Sky 2 (CS2) has been the successor programme within the 8th EU R&D program H2020 and has had an additional objective to those of the original Clean Sky: to keep on develop new technologies for reducing environmental footprint and a strong aeronautical industry and supply chain in Europe to compete globally. Aernnova has been a partner of Clean Sky and CS2 during the last fourteen years and have dedicated numerous resources for the development, design, manufacture, and validation of laminar wing like type surfaces. The challenges have included natural laminar flow and hybrid laminar flow control technology demonstrators. Aernnova, together with partners, have integrated new solutions in ground and fly demonstrators go answer the technological challenges and a further step in its commitment to play a leading role towards a low-emission and competitive aeronautical industry. This contribution summarizes these developments and demonstrators.
