A Local linear stability analysis (LST) is conducted on experimental boundary layer profiles in the fore position of the LSB. %G English %2 https://hal.science/hal-03773978/document %2 https://hal.science/hal-03773978/file/DMPE22027.1646229458.pdf %L hal-03773978 %U https://hal.science/hal-03773978 %~ ONERA %~ ONERA-MIP %~ FONISEN %~ FONISEN-X-OAD
