Abstract
The aim of this paper is to investigate the vortex-sound modelling and its impacts on AGAR model prediction capabilities, considering the available validation perimeter i.e. P80 and POD-Y SRMs. AGAR model parameters can be related with ballistic properties and geometrical quantities, reducing the model calibration requirements and therefore improving its prediction capabilities. This activity represents, thus, a further step in the consolidation and validation of the AGAR model for the characterization of pressure oscillations in aft-nocyl SRMs which is fundamental for both the in operation launch vehicle, i.e. VEGA, and the future ones, i.e. Ariane 6 and VEGA-C/VEGA-| File | Dimensione | Formato | |
