Numerical simulation of chemical erosion in Vega solid-rocket-motor nozzles
The erosion of rocket-nozzle ablative thermal protection materials during the solid-rocket-motor burning time
needs to be accounted for to get reliable performance predictions, especially for long-duration firings and/or small
nozzles (that is, upper stages). This work numerically investigates the erosion behavior as a function of chamber
conditions for the nozzles of the Vega launch vehicle solid rocket motors: Zefiro 9, Zefiro 23, and P80. This study has
