This study aims to discuss and analyze Pressure Oscillations phenomena occurring during the quasi-steady state phase of Vega P80 Solid Rocket Motor. The experimental PO data are investigated, showing the key role played by hydrodynamic instabilities and thermoacoustic coupling due to aluminum combustion. The experimental P80 SRM PO envelopes are then reconstructed through a Q1D model named TAHR, showing the capability of the model to represent, with good correlation, the whole PO scenario and highlighting the possible role of aluminum combustion as the root cause for PO signature and levels dispersion.
