Abstract
Current state of the art of numerical codes does not allow the aerodynamic and thermal design of hypersonic vehicles, as well as of space shuttles, by means of computer simulations only. The need arises for proper wind tunnel testing and detailed heat flux measurements. In this article significant results referring to flow visualizations and heat transfer measurements performed. with an infrared (IR) scanning radiometer in a blow-down hypersonic wind tunnel on simple and double ellipsoidal models are discussed. Comparisons of IR data with oil film flow visualizations, thermocouple measurements, and computational predictions are made.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
