MEFIA – Novel Physics Methodologies for Aerospace

Obiettivo

This project aims to implement innovative physical diagnostics developed by SUN-INFN (Second University of Naples - National Institute of Nuclear Physics) to measure the wearing of materials used in the aerospace field (e.g., Ablative, UHTC, components of the Plasma Wind Tunnel - PWT). The innovative physical technique (Surface Layer Implantation - SLI), using a beam of radioactive ions (7Be), allows to have information on the material wearing speed (recession rate) in a high-sensitivity (from microns to centimeters), not intrusive, remote and on-line way overcoming the techniques used in the current aerospace scenario. This new technique involves the implantation of radioactive ions at the CIRCE (Center for Isotopic Research on the Cultural and Environmental heritage) laboratory (SUN-INFN-INNOVA) and the measurement in the operating condition. The CIRCE, present in Caserta (Campania region), is the only laboratory where this methodology is available. Moreover stoichiometric and thermometric informations, in an emissivity free configuration, may be obtained respectively from the AMS and IBA and the DUAL COLOR techniques. The purpose of the activity is to develop an innovative method that allows simultaneously to get information on the wearing speed of materials (eg., TPS) - and on the temperature at which it occurs - to achieve in the future the use of the techniques in-flight.


Attività nel progetto CIRA

Another activity is to carry out a feasibility study for the development of a future laboratory system that will fulfill the following: One of the CIRA task is the use of internal CFD codes for the extraterrestrial reentry (e.g., Martians and Jovians) simulations. These codes are evaluated experimentally with great difficulty due to the lack of experimental systems. Nuclear diagnostic for spatial and pressure profile measurements, using small particle accelerators, on supersonic/hypersonic gas jets (e.g., hydrogen, helium and CO2) may be possible thanks to the INFN support, since such systems are present for measurements of nuclear reactions for astrophysical interest. Already small jet changes, at low enthalpy (cold jet), would make them useful for the validation of the CFD codes, comparing the experimental results with simulations and validating a numerical model that could be used in future analysis to predict both the actual conditions in the extraterrestrial reentry and failures of thermo-structural components with FEM analysis. In addition trying to get higher enthalpy (warm jet), would make possible the experimental characterization of TPS material of a few centimeters. This would allow on one hand to obtain the validation of thermo-structural FEM codes and on the other to obtain a laboratory instrument at variable gas, of daily use, for the development of diagnostics  (Nuclear, Optical, Spectroscopic, Thermographic) to be then used on the big plasma wind facility  like SCIROCCO/GHIBLI.
