Several breakdown scenarios to turbulence of a supersonic flat-plate boundary layer with and without an adverse pressure gradient (APG) at Mach 3 are investigated using Direct Numerical Simulations (DNS). The effects of APG on an oblique breakdown and on "classical" fundamental and subharmonic breakdown mechanisms are studied. For the Mach number under investigation the boundary layer is most unstable with respect to a first mode three-dimensional wave according to Linear Stability Theory (LST). Therefore, "oblique" secondary instability mechanisms were investigated where both primary and secondary disturbance waves are three-dimensional. These breakdown mechanisms are scrutinized in order to gain insight with respect to their relevance for practical applications.
