Abstract: The influence of the thickness and porosity of a passive porous coating on the development of natural disturbances in a hypersonic boundary layer has been studied for the sharp cone model at a Mach number of $\mathrm{M}_\infty$ = 6, zero angle of attack, and Reynolds numbers $\mathrm{Re}_{1\infty}$. It is established that there exists an optimum thickness of the passive porous coating that corresponds to the maximum stabilization of second-mode disturbances.
