A methodology for the integrated design of hypersonic vehicles has been presented in (1) and (2); it relies on nose to tail CFD simulations obtained using a domain decomposition method which integrates different flow solvers, chosen to adapt locally the modelization to the flow physics, with the objective of attaining the "just needed accuracy". We present here a progress report on an effort to validate this methodology, through an analysis of the sensitivity of the predictions of overall performances to the level of modelization, and through the rebuilding of the aerothermodynamic caracteristics of an "Integrated Validation Object", for which wind tunnel data must be available. The objective is to obtain a quantification of the uncertainties on the predictions of a vehicle's global performances, by transposing to flight conditions the results of the ground analysis.
