Indraft Tunnel for High-Speed Aerodynamics Research

Abstract

The Stevens Shock Tunnel was supported by this DURIP. In this report, we present an optimization process for the design of converging-diverging nozzle contours and preliminary experimental results. The optimization is carried out in three steps: contour definition, inviscid optimization, and viscous optimization. Preliminary experiments are carried out to assess flow quality. Slight under-tailoring is observed in the reservoir pressure and the nozzle code somewhat under-predicts the Pitot pressure, and rectifying this discrepancy will be a focus of future work. A key positive takeaway from these experiments is the approximately 320~mm (12.5~inch) nominally inviscid core.
