APPARATUS Multinozzle-Duct Pilot Model The test apparatus was a 1/3-scale model of a proposed full-scale tunnel. It consisted of three nozzles, used to expand the flow, followed by a constant- area duct. The basic geometry and dimensions of the model apparatus are shown in figure 1.

A pilot multinozzle and duct were tested at ambient enthalpy to evaluate the suitability of such apparatus for testing thermal protection system panels mounted in the sidewalls of the duct downstream of the nozzle array.
