    Abstract
    This paper presents the study of a concept of Ariane-5 evolution by means of replacement of two solid-propellant boosters EAP with two Liquid-propellant Reusable Fly-Back Boosters called “Bargouzine”. The main design feature of the reference RFBB is LOX/LH2 propellant, the  canard aerodynamic configuration with delta wings and rocket engines derived from Vulcain-2 identical to that of  the central core except for the nozzle length. After separation RFBBs return back by use of air breathing engines mounted in the aft part and than landing on a runway.
 
The aim of the study is a more detailed investigation of critical technology issues concerning reliability, re-usability and maintenance requirements. The study was performed in three main phases: system trade-off, technical consolidation, programmatic synthesis. The system trade-off includes comparative analysis of two systems with 3 and 4 engines on each RFBB and determination of the necessary thrust level taking into account thrust reservation for emergency situations. Besides, this phase contains trade-off on booster aerodynamic configurations and abort scenario analysis.
The second phase includes studying of controllability during the ascent phase and separation, thermo-mechanical design, development of ground interfaces and attachment means, turbojets engine analysis taking into account reusability.

The project also contains preliminary cost estimation and some programmatic aspects such as risk analysis and fleet size definition.
