AbstractIn the framework of Advanced Space Transportation Systems Studies sponsored by CNES in 2006, a study called “BARGOUZIN” was performed by a joint team led by ASTRIUM ST and TSNIIMASH. Beyond these leaders, the team comprised MOLNIYA, DASSAULT AVIATION and SNECMA as subcontractors.The “BARGOUZIN” concept is a liquid fuelled fly-back booster (LFBB), mounted on the ARIANE 5 central core stage in place of the current solid rocket booster. The main originality of the concept lies in the fact that the “BARGOUZIN” features a cluster of VULCAIN II engines, similar to the one mounted on the central core stage of ARIANE 5. An astute permutation strategy, between the booster engines and central core engine is expected to lead to significant cost reductions. The following aspects were addressed during the preliminary system study:engine number per booster trade-off/abort scenario analysis,aerodynamic consolidation,engine reliability,ascent controllability,ground interfacesseparation sequence analysis,programmatics.These topics will be briefly presented and synthesized in this paper, giving an overview of the credibility of the concept.
