Plum Brook Station 42-Inch Hypersonic Tunnel Facility

The Direct Connect Combustion Rig, used for rocket-based-combined-cycle development testing, converted the HTF test section from an open-jet to a closed configuration that simulates only an engine’s combustion chamber. The smaller-diameter pipe is a dummy insert used for calibration. The model support and injection system used with open-jet testing is clearly visible over the tunnel.
