Abstract:
Within the framework of the asymptotic theory of free interaction, the instability of the boundary layer over the compliant plate at supersonic speeds of the incoming flow with respect to non-viscous disturbances is studied. Unstable non-viscous disturbances are shown to exist only when the inertance of the plate is taken into account, and the damping of the plate plays a significant stabilizing role. Increasing the elasticity, bending stiffness, and longitudinal tension of the plate also stabilizes the flow.
