Abstract
Here, the project of a new experimental facility to be installed at the Aerodynamics Division of the Institute of Aeronautics and Space is presented. The new facility will provide means to perform experimental campaigns to analyze the flow behavior at different rocket nozzle concepts using cold gas. The cold gas flow will be obtained from a modification of the Pilot Transonic Wind Tunnel air system. The new installation will enable safer and cheaper experiments, since the cold gas experimental procedures do not demand fuel storage and burn and security measures are much less severe. Furthermore, experiments can be carried out with different types of sensors, typically used in wind tunnel tests, and the optical access is greatly improved enabling the use of optical techniques for the characterization of flow properties inside the nozzles, such as pressure (PSP) and temperature (TSP) sensitive painting.
