Fluid-Structure simulations are performed on a single gore of a flight-scale ADEPT decelerator configuration to study interactions between turbulent wake and carbon cloth at supersonic Venus entry conditions. Three areas of the geometry are examined; the center of the gore(acreage), the shoulder where the flow is turned, and the trailing edge of the gore. Fully coupled fluid-structure interaction (FSI) simulations are performed at Mach 1.5. Results are provided showing that large scale motion of the acreage is highly damped, that the shoulder of the gore has a tendency to sharpen due to the strong pressure gradient of the turning flow, and that the trailing edge undergoes small amplitude displacements due to pressure variations, accompanied by low amplitude buzz in the range of 70-80 Hz.
