N2 - This paper describes an updated nozzle centerbody, which acts as both a flow terminator and a debris blocker in the Stevens Shock Tunnel. A redesigned centerbody that slides on linear bearings was implemented to reduce tunnel turn-around time, increase plugging-time control, and improve shot-to-shot consistency in the facility. Pressure traces for shock tunnel experiments using the new centerbody design are presented to demonstrate comparable behavior to the previous version. Design features are discussed, and the new centerbody design will be further evaluated in future experimental work. A preliminary computational fluid dynamics analysis is also presented to explore and describe the plugging action of the debris blocker.
