The development of disturbances in a supersonic wake (free viscous layer and regular wake) behind a flat plate, both in linear and in nonlinear phases of development was investigated. The influence of several factors (Mach and Reynolds numbers, temperature factor, thickness of a plate, length of its stern) on the wake stability was studied.
