N2 - In summer 2005, based upon the DMA's validated experience on the ignition transient of solid propellent rockets simulation and analysis, a brand new solution to control pressure oscillations at ignition was proposed for the solid rocket motors of the new VEGA Launcher of the European Space Agency. This solution, based upon the utilization of Helium instead of Nitrogen as a chamber pressuring gas, was presented and discussed for the first time during the last JPC in Tucson (AIAA-2005-4165). Being deeply analyzed and evaluated together with ESA, ELY and AVIO specialists, the proposed solution has been finally implemented in the Zefiro9-DM0 motor successfully tested in the Salto dl Quirra inter-force missile test centre in Sardinia on December 21st 2005. Test's results and experimental measurements have clearly confirmed what was predicted, not only validating Helium pressurization as a solution able to completely solve the ignition pressure oscillations issue, but also further enhancing the confidence on the prediction capabilities of the solid rocket motors Internal ballistics simulation models developed by the DMA.
