Results indicate the presence of shock-wave oscillations that induce unsteady loads and can cause serious damage to the aircraft. The work focusses on the onset of the bu\ufb00et unsteadiness and its control by means of passive control devices. Reynolds-averaged Navier-Stokes simulations using the Spalart-Allmaras turbulence model are considered with vortex generators fully resolved and included into the computational grid. It is shown how mechanical vortex generators modify the \ufb02ow \ufb01eld downstream of the shock location by suppressing separation and are thus able to delay bu\ufb00et onset.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/11\/IFASD-2015-088.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>S.
