Disruptive research approach for GSI-model consolidation through on-ground and in-flight analyses (DRAGROUNDFLIGHT)
Abstract
Among all the phenomena studied in hypersonics, ablation has been, and still is, the subject of many investigations given its strong impact on the thermal management of vehicles. A state-of-the-art model, which represent a significant advancement for the type of experimental techniques used, the quality of the data obtained, and the multiscale numerical analyses employed, has been recently developed by a US team through the AFOSR Grant No. FA9550-17-1-0057 on Nonequilibrium Gas-Surface Interactions at High Temperature.Experimental data are the basic ingredients for the validation and calibration of computational models. However, full simulation of hypersonic flight conditions is still out of reach in today s high-enthalpy facilities. Therefore, developing innovative testing strategies, that rely on local duplication, extrapolation, or scaling of the particular phenomenon under investigation, is thus necessary to push the frontiers of knowledge.This project, entitled Disruptive research approach for GSI-model consolidation through on-ground and in-ight analyses (DRAGROUNDFLIGHT), aims to define and implement an innovative testing strategy for the calibration and complete validation of ablation models. We will prepare potential in-flight experiments on CubeSats in synergy with on-ground experiments, defined through numerical simulations and experimental measurements in the VKI inductively-coupled plasma torch Plasmatron facility. Both simulation and experimental data will be consistently linked through rigorous uncertainty quantification techniques.
