Atmospherical particles can be the main reason for boundary layer instability, leading to a laminar-turbulent transition on aerodynamically smooth bodies. On the height of about 20-30 km, the concentration of submicron particles is relatively high. Such particles are able to hit leading edges of an aircraft, exciting wave packets of first and/or second mode. During propagating downstream, these wave packets are growing, reaching critical amplitude and turning into turbulent spots. The article introduces the results of numerical computation of boundary layer receptivity to solid particles near the blunt leading edge of the plate in flow with Mach number 6.
