| Abstract: | In the present study, we examined, both experimentally and theoretically, the influence of surface permeability on the stability
and laminar-turbulent transition of supersonic boundary layer at free-stream Mach number M∞ = 2. A satisfactory agreement was obtained between the data calculated by the linear theory of stability and the data obtained
in experiments with natural disturbances performed on models with different porous inserts. |
