PPRIME Institute and CNES have initiated research activities to investigate the propulsion behaviour of liquid storable propellants, and the related phenomena: atomization of propellants, ignition ability, combustion stability, propulsion efficiency. For this purpose, a specific facility " PERGOLA " has been designed with high modularity, allowing physical diagnostics in a pressurized combustor featuring relevant flow conditions (a few hundred g/s, 5 MPa). The first results demonstrate the capability of PERGOLA facility and characterize the behaviour of a reference storable bipropellant system: ethanol and hydrogen peroxide. The overall combustion performance is also characterized in terms of stability, characteristic velocity and efficiency.
