Abstract
In the present work a numerical study of pressure oscillation frequencies and amplitudes in Ariane 5 MPS P230 boosters will be presented.

Numerical results have been compared and validated against experimental data, showing in all cases an impressive numerical accuracy. In the case of numerical simulation performed on P230 SRM pressure oscillation amplitude shows a difference lower than 5% when compared with averaged flight data.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
