A direct time domain approach which is composed of a free flying finite element structure coupled to an unsteady potential flow method was implemented. This method is used to investigate the impact of fixed-axis and mean-axis boundary conditions. Furthermore the impact of quasisteady and unsteady aerodynamic modeling to the aircraft response is investigated. A modal truncation method is introduced which is based on the significance of modes in characteristic loadcases. Moreover a fast time capable reduced order model is generated from the original model allowing fast time simulations with similar accuracy.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/11\/IFASD-2015-068.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>K.
