Oxygen Rich Staged Combustion (ORSC) engine cycle is being evaluated
as part of the Next Generation Launch Technology (NGLT). RS-84
engine is a candidate propulsion system for the ORSC cycle. The
RS-84 utilizes liquid oxygen and RP-1 as propellants. The RS-84
will be designed to be 65% throttleable, have a 100 cycle life
at the full powerlevel condition, while exhibiting low maintenance.
Key components of the RS-84 engine system are the subscale oxygen-rich
(Ox-rich) preburner and the main injector using LOX/RP-1 propellants.
A key objective is to demonstrate operational characteristics
of oxygen rich staged combustion subsystem to reduce risk for
full scale design and development. A full-scale "Battleship"
Preburner will be designed and tested at E1 after the sub-scale
