Acoustic and turbulent boundary-layer flow loadings over a flexible structure are used to study the spatial-temporal dynamics of the response of the structure. The stability of the spatial phase synchronization and desynchronization by an active exte

An investigation of the control of turbulent boundary-layer e ow over e exible and rigid surfaces downstream of a concave‐convex geometry has been made. The concave ‐convex curvature induces centrifugal forces and a pressure gradient that affect

Nonlinear response of a flexible curved panel exhibiting bifurcation to fully developed chaos is demonstrated along with the sensitivity to small perturbations from the initial forcing. The response is determined from the measured time series at two

The property of sensitive dependence on initial forcing may be used as an effective trigger of changes in a system response and, thus, used to redistribute energy favorably and efficiently. One unstable periodic orbit was selected from each experimen

The control of shock noise or screech from a jet near a flexible structure is discussed. The pressure from the supersonic jet consists of a shock with spiral and flapping nonaxisymmetric modes superimposed on broadband response. This shock induces a

Experimental data are presented to show evidence of chaotic response of two adjacent aircraft panels forced by a turbulent boundary layer and pure tone sound. The experiments are a simulation of boundary-layer and fan noise loads on a fuselage sidewa

We numerically solve a model of sound generated in an ideally expanded two-dimensional supersonic (Mach 2) jet. Two configurations are considered: 1) a free jet and 2) an installed jet with a nearby array of flexible aircraft type panels. In the late

Measurements are made of the response and acoustic radiation of a panel structure forced by a constantly accelerating subsonic turbulent boundary layer with superimposed pure-tone sound in a wind tunnel. Both panel loading and response exhibit convec

A model of a high subsonic jet with a nearby array ofexible, aircraft-type panels is studied numerically in two dimensions. The jet is excited by a limited duration, spatially localized starter pulse in the potential core. The long time evolution of
