Airbus Defence and Space is partner of a consortium which, as part of the Clean Aviation Strategic Research and Innovation Agenda (SRIA), is responsible of the engineering solution of a short-range (500-1000 km) Hybrid-Electric Regional Aircraft, one of the new aircraft architectures that will thrust the aviation towards 2050 climate neutrality. This paper summarises the aircraft architecture solution and the aeroelastic challenges\/technologies that will be developed during the different phases of the project. Some of the technologies developed for supporting the design of the HERA aircraft are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The Hybrid-Electric Regional Architecture (HERA) aircraft will include distributed propeller-type propulsion with inertia and aerodynamic impacts on wing component that<br>shall be considered thru high-fidelity simulations. These simulations are performed using a Fluid-Structure Interaction (FSI) procedure based on MSC.Nastran coupled with<br>different High-Fidelity aerodynamics solvers. A graphical workbench DYNFSI is being developed to increase robustness and enhance the user experience when calculating 1-way or 2-way unsteady aerodynamics.<br>2.The rigid-body response of the aircraft will be improved by introducing the Integrated<br>Flexible Aircraft Model (IFAM), with improved coupling between flight mechanics and<br>aeroelastic formulation, all integrated in the industrial procedure of Airbus Defence and<br>Space (using DYNRESP software) to calculate Dynamic Loads.<br><\/li>\n<\/ol>\n\n\n\n<p>The Structural Dynamics and Aeroelasticity in the HERA project are described with emphasis on the previous two points and future activities (LCOs\/flutter suppression activities, wind-tunnel tests, digitalization of methods and tools, etc.)<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/03\/170.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Emilio Santos, Alan Serena, Mordechay Karpel, Felix Arevalo, Hector Climent<\/b><\/p>\n<p>DOI Number: https:\/\/doi.org\/10.82439\/ceas-ifasd-2024-170<\/p>\n<p>Conference number: IFASD-2024-170<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3028,3022],"tags":[3118,3120,3119],"class_list":["post-19295","post","type-post","status-publish","format-standard","hentry","category-events","category-computational-aeroelasticity-1-ifasd-2024","category-ifasd-2024","tag-clean-aviation","tag-distributed-propulsion","tag-hybrid-electric-regional-architecture","category-993","category-3028","category-3022","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19295","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=19295"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19295\/revisions"}],"predecessor-version":[{"id":20341,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19295\/revisions\/20341"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=19295"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=19295"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=19295"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
