Performance and Business Case Impact Assessment for Launch Systems Utilizing RDRE Propulsion

The AFRL has been examining the potential of Rotating Detonation Rocket Engine technology through both high-fidelity numerical simulations as well as ground test programs. To further understand the merits of this type of liquid rocket propulsion, an impact assessment was recently conducted to quantify the performance improvements and gains when a notional expendable launch system is retrofitted with RDRE engines. For this effort, optimal design parameters for the RDRE engine were selected that maximized the delivered payload to orbit. Additionally, the impact to the launch vehicle operator's business case and financial viability were assessed, treating items such as the RDRE engine cost parametrically.
