industry. The emergence of new technologies has allowed new actors to develop smaller and more_x000D_
cost-effective satellites to perform the same missions. However, due to the lack of operational dedicated_x000D_
launchers, microsatellites are often constrained to launch as secondary payloads alongside larger satellites._x000D_
Chemical propulsion in the aerospace sector is currently dominated by two rocket design paradigms,_x000D_
differentiated by the phases of the reactants used, solid in one case and either liquid of gaseous in the other._x000D_
Our partner Reaction Dynamics Lab has been pioneering a novel type of rocket propulsion technology,_x000D_
experimentally demonstrated recently using a static fire test. Hybrid rocket engines, where liquid or gaseous_x000D_
oxidizer are stored separately from the solid fuel, can bring key advantages with regards to safety without_x000D_
compromising performance. When solid fuels rubbers are used for the fuel matrix in hybrid rocket motors, the_x000D_
regression rate is very low compared to solid rockets. This drawback has been partially addressed by the_x000D_
introduction of the concept of liquefying solid fuels matrix. It is anticipated that the combustion efficiency of_x000D_
these motord will depend on the flow properties of the melted fuel, but the characteristics of this relationship_x000D_
remained to be identified. The investigation that will be supported by this grant is aimed at identifying the_x000D_
effects of the melted fuel rheological properties on the combustion efficiency of hybrid rocket motors., program purpose french : Access to space and suborbital flights are of critical importance to a broad range of fields of science and_x000D_
