Contratto CIRA Università degli studi “Roma Tre“ - Relazione 4: BL properties in the experimental flow conditions – Data reduction, wall pressure fluctuations properties at transonic and supersonic flow conditions”

The present report concerns mainly with the analysis of the experimental data obtained in the supersonic and transonic wind tunnel facilities where the measurement campaigns have been carried out. A selected set of the most relevant results obtained from the post-processing of the experimental data is presented and discussed along with the main properties of the boundary layer obtained on the launcher model from the numerical simulations. The selected results presented here allows for a preliminary estimation of the most relevant effects of the main governing parameters on the spectral quantities of interest and of relevance for the successive theoretical developments. Thus, the bases for the analytical modelling and for the full scale extrapolations are also given here but the details on those topics and the extrapolation results are left for the successive (last) report.
