Researchers can use mathematical models to predict how an aircraft will behave under rapidly changing conditions. Different propulsion systems such as kerosene, hydrogen or electricity, and light and strong materials such as composites reinforced with carbon fibre can be investigated using these models. \u201cAs a passenger, you don\u2019t notice that the aircraft\u2019s wings and fuselage are made of composites that are lighter&nbsp; than aluminium, so that the plane uses less fuel and flies more economically and cleanly. Taken together, though, these developments make a big difference for our climate and environment. It\u2019s great to be part of that; there are more than seven hundred of us at NLR working every day on improving aviation.\u201d<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link advgb-dyn-aaa6122c\"><a href=\"https:\/\/innovationorigins.com\/nl\/demonstraties-met-e-vliegtuig-op-aruba-dit-is-de-toekomst\/\" class=\"vlp-link\" title=\"Demonstraties met e-vliegtuig op Aruba: \u2018Dit is de toekomst\u2019\" rel=\"nofollow\" target=\"_blank\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><img decoding=\"async\" src=\"https:\/\/innovationorigins.com\/app\/uploads\/2022\/11\/NLR-Pipistrel-op-Aruba_nov-22_05.jpg\" style=\"max-width: 150px; max-height: 150px\" \/><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">Demonstraties met e-vliegtuig op Aruba: \u2018Dit is de toekomst\u2019<\/div><div class=\"vlp-block-1 vlp-link-summary\">Op Aruba vinden er deze week demonstratievluchten plaats met de PipiStrel Velis Electro, het elektrisch aangedreven onderzoeksvliegtuig van Koninklijke NLR.<\/div><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\">Bringing different disciplines together<\/h2>\n\n\n\n<p>Optimum use of composites for aircraft parts is complicated. A composite always consists of two or more materials. \u201dThese can be &nbsp;a thermoplastic matrix and carbon fibres, for example,\u201d explains Jos. \u201cThermoplastics, unlike thermosetting materials, melt when heated. The ultra-strong carbon fibres are embedded in that thermoplastic, so to speak, as long strands in a specific orientations.\u201d An aircraft wing, for instance, is made of very thin composite layers (only a few tenths of a millimetre thick) stacked on top of one other to form a sheet just a few millimetres thick.<\/p>\n\n\n\n<p>One technique for bonding these types of thermoplastic-carbon composites is welding with electromagnetic induction. The carbon fibres in the material conduct electricity very well, but the matrix material \u2013the thermoplastic \u2013 has a high electrical resistance. \u201dBecause the fibres conduct, you can heat the matrix using an induction mechanism. The orientation of the fibres is critical for this. In those stacked layers of composite, there are fibres in all kinds of orientations affecting the distribution of heat within the material. So you\u2019re dealing with very complex phenomena on a very small scale.\u201d<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>\u201c<\/em>It\u2019s a huge challenge, but I love it when it works out in the end.<em>\u201d<\/em><\/p>\n<cite>Jos Vankan<\/cite><\/blockquote>\n\n\n\n<p>This research project lasted five years and expanded our knowledge about using composites in the production processes of fuselage or wing materials. \u201cWhen you\u2019re doing research involving a range of disciplines such as electromagnetics, mechanics, materials science and manufacturing engineering, you really have to understand each other well. That\u2019s a huge challenge, but I love it when it works out in the end.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Hybrid configuration<\/h2>\n\n\n\n<p>On behalf of NLR, Jos is also involved in hybrid electric propulsion projects, in which aircraft use different energy sources and drive mechanisms simultaneously or in series during the flight. The combination of energy sources should make it possible to optimise overall energy efficiency and reduce fuel consumption.&nbsp;\u201cSuppose you house batteries in the wings instead of in the fuselage. How far can you fly then and with how many passengers? What is the impact of using a slightly different engine? We can use models to predict the answers to these questions as best we can.\u201d<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link advgb-dyn-949add52\"><a href=\"https:\/\/ioplus.nl\/archive\/en\/for-electric-aviation-the-entire-ecosystem-must-be-involved\/\" class=\"vlp-link\" title=\"For electric aviation, the entire ecosystem must be involved\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">For electric aviation, the entire ecosystem must be involved<\/div><div class=\"vlp-block-1 vlp-link-summary\">While power plants and heavy industry are making ever greater strides in the transition to a carbon-free sector, aviation is struggling. <\/div><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\">From fundamental to practically-oriented research<\/h2>\n\n\n\n<p><a href=\"https:\/\/www.nlr.org\/wp-content\/uploads\/2023\/07\/Jos-eigen-foto-scaled.jpg\"><\/a>Rewind to 1996: Jos has just completed his PhD on the microstructure of biological material at Maastricht University and TU Eindhoven. He is sending dozens of job applications to companies where he hopes to do practically-oriented research \u2013 Philips, DSM, KNMI\u2026 they were all part of the equation. It was quite a quest because the job market at the end of the nineties was totally different to the job market now.&nbsp;Until he gets a response from NLR. \u201cI didn\u2019t have much to do with aviation until then,\u201d Jos confesses with a smile. Yet it turns out to be a golden match because, twenty-five years later, he\u2019s still walking around the Netherlands Aerospace Centre corridors in Amsterdam. He is not the proud type and above all wants to do his job well. \u201cIn that respect, I\u2019m more of a down-to-earth North Hollander than an ambitious Limburger,\u201d he concludes with a grin. He moved to the Amsterdam area in 1996 for his job at NLR. It was a minor culture shock, but now he feels at home.<\/p>\n\n\n\n<p>Sustainable, greener aviation has been a leitmotif throughout his career. So the idea that the industry has only recently started looking at how to fly more economically and efficiently is a misconception the researcher wants to dispel. \u201cOver the last fifty years, the amount of kerosene required by an aircraft has fallen drastically. The industry has made huge strides. I sometimes miss that nuance. The tone in public discourse is that aviation is polluting and harmful. But it\u2019s not so much that flying is polluting: travelling very quickly a very long way is polluting, whether by plane or otherwise.\u201d<\/p>\n\n\n\n<p>As it has over the past fifty years, the aviation engineer expects the industry to become even more energy-efficient in the next half century. However, the more economical, cleaner and more efficient aviation becomes, the more difficult further improvements become. \u201dIt\u2019s a big challenge, one that the whole industry is working very hard on. I enjoy playing my part in that.\u201d<\/p>\n\n\n\n<p><em>Next episode (August-September 2023): Ellen van Leeuwen, principal engineer, on her drive for data for noise regulations for the Dutch Royal Air Force<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jos Vankan is a principal scientist at the Royal Netherlands Aerospace Centre (NLR).
