A new fuel regression model, based on the mass/energy balance at the fuel surface, is implemented in the computational fluid dynamics software CEDRE. The modeling aims at generalizing a practical use of the fuel regression model to improve, by means of numerical simulations, the knowledge about aerothermochemical phenomena in hybrid rocket engines....
An experimental test campaign has been conducted by Safran and ONERA in order to generate a database on an annular effusion cooling system. Different effusion cooling patterns have been tested in various flow field conditions, representative of those encountered in real aeronautical combustors in terms of Reynolds number in the perforations, blowin...
A test series aimed at investigating wall temperatures and heat fluxes in a subscale rocket engine combustion chamber operated with oxygen and methane was achieved at the Mascotte test facility. A total of nearly one hundred and fifty stabilized operating points were reached, enabling to cover a wide operating domain, ranging from subcritical to su...
Even though the technology of cryogenic rocket engines is well mastered today, and has been applied successfully in many launchers all over the world, research activities on the various elementary or coupled processes involved in these complex systems are still relevant and useful for future developments, cost reduction, and knowledge improvement.T...
