Development of SmarT Eco-friendly anticontamination technologies for LAminaR wings

Descripción del proyecto

Una tecnología anticontaminación inteligente para el flujo laminar en aeronaves

La reducción de la resistencia aerodinámica de las aeronaves es importante para disminuir su consumo de combustible y para aumentar el rendimiento global. La industria aeronáutica está buscando métodos para garantizar el flujo laminar y reducir los riesgos asociados a las turbulencias. Los restos de insectos sobre las alas representan una importante preocupación operativa debido a que afectan al flujo laminar. El proyecto financiado con fondos europeos STELLAR busca desarrollar aplicaciones de limpieza y anticontaminación que sean eficaces y permanentes a partir de conocimientos precisos sobre las características de los restos de los insectos. El proyecto investigará la transformación bioquímica de la hemolinfa (el líquido equivalente a la sangre de la mayoría de los insectos) durante el vuelo, además de evaluar su impacto sobre el exterior de las aeronaves. Por otra parte, identificará las propiedades de las superficies que atraen la mayor parte de las adhesiones de restos de insectos.

Objetivo

The aircraft industry is facing issues with the increase of drag directly impacting the fuel consumption of the fleet. Achieving natural laminar flow requires high surface quality. Tiny air flow disturbances at the surface can indeed cause an early transition from laminar to turbulent flow. The accumulation of insect debris on the leading edge of laminar wings has been recognized as one of the most significant operational concerns associated with laminar flow. The main objective of STELLAR is to develop efficient and durable anticontamination coating and cleaning solutions designed following a deep understanding of the insect residues properties. Hence, STELLAR project seeks to gain insight on the understanding of the biochemical transformation of hemolymph during flight phases and the consequent physico-chemical modification and interaction with the aircraft surface. In order to meet these goals, the project consortium gathers cutting edge multidisciplinary knowledge and the needed facilities to provide a deep understanding of the insect contamination issues. STELLAR approach has the potential to significantly enhance the current understanding of the key issues and highlight which surface characteristics have the greatest influence on insect residue adhesion. From this approach, new coating and cleaning solutions will be developed. The knowledge acquired and the coating and cleaning solutions developed will be evaluated through large scale tests: 1) wind tunnel tests will allow the simulation of the extreme conditions occuring during flights and 2) real aircraft tests, including short flight tests (on test aircraft) and long flight tests (on commercial aircraft), operating at higher altitudes will allow a full validation of the new solutions developed by the STELLAR project.
