The problem of supersonic flow past a flat plate bearing a triangular vibrator which begins to execute harmonic oscillations in the unperturbed boundary layer, is studied. Both the plate and vibrator are assumed to be thermally insulated. The size of the vibrator and the frequency of its oscillations are such that the flow can be described by the equations for a boundary layer with selfinduced pressure. The oscillation amplitude is assumed to be small, and this enables the equations to be linearized. The linear formulation is used to study the problem where the pressure reaches a steady-state periodic mode. The problem of the vibrator is used to solve the problem of the propagation of non-steady perturbations both upstream and downstream.
