Abstract: The effect of passive porous coatings of different lengths on the second mode of disturbances in a hypersonic boundary layer is considered. The experiments are performed in a flow with a free-stream Mach number $\mathrm{M}=5.8$ and five values of the unit Reynolds number around a sharp cone with an apex half-angle equal to $7^{\circ}$, which is aligned at a zero angle of attack. One half of the model surface along its generatrix is covered by a porous material, and the other part is a solid surface. Pressure fluctuations on the model surface are measured. It is found that application of a passive porous coating can either decrease or increase the amplitude of the second mode. The length of the passive porous coating corresponding to the maximum efficiency of its action on flow disturbances and the coating length that increases the amplitude of the second mode are found.
Keywords: experiment, hypersonic boundary layer, second mode of disturbances, passive porous coating.
