In the framework of the weakly nonlinear stability theory investigates soft and hard product of the periodic fluctuations in a supersonic boundary layer at Mach number M = 2. The model includes the effects of blooming (the product of the stationary secondary harmonics and the generation of perturbations of the double frequency). It is shown that in the framework of this model on the lower branch of the neutral curve appear region subcritical growth. This effect directly connected with the influence of compressibility. Keywords:
boundary layers, compressible flow, hydrodynamic stability, weakly nonlinear theory.
