Abstract
The evolution of adaptive shock control bump (SCB) design has seen the system flexibility
increase to a point where the aerodynamic loading can affect the deformation of the
plate. By studying the effects of a flexible plate subject to transonic flow the fluid structure
interaction can be investigated. In this study an array of thin plates (0.4 and 0.6 mm)
with different aspect ratios (1 and 1.33) are exposed to a Mach 1.4 normal shockwave.
PIV is used in combination with Schlieren imaging to provide a detailed view of the flow
curvature surrounding the plate as well as the global shock structure. A technique that
extracts the plate deformation from the PIV images is also presented which provides fluid
and structural information for each test. The relationship between plate and flow angle
is discussed as well as the effect of plate stiffness and free stream influence of each plate
configuration.
