The three-stream adaptive cycle design can direct air to the bypass third stream for increased fuel efficiency and cooling or to the core and fan streams for additional thrust and performance. The engine thrust has not been disclosed, although it is speculated by aviation reporters to be in the 35,000–40,000 lbf (156–178 kN) thrust class. [2]
lh 2 / lox The Exploration Upper Stage (EUS) is a rocket stage under development that will be used for future flights of NASA 's Space Launch System (SLS). Used on SLS Block 1B and Block 2, it will replace the SLS Block 1's Interim Cryogenic Propulsion Stage .
The development of the engine started at Ivchenko-Progress of Zaporizhzhia, Ukraine in 1999. The engine was originally intended for the Yakovlev Yak-130 trainer aircraft. An afterburning version, the AI-222-25F (from Russian/Ukrainian term "Форсаж") is also available with thrust vectoring.
The results from the test firings of test motors SL-1 and SL-2 showed a maximum thrust value of 3.5 million pounds (15.7 meganewtons) and a burn time of 114 seconds. The firings used six tons of PBAN propellant a second, producing a column of white-hot fire visible in Miami 31 miles away. [ 8 ]

The engine was developed in the second half of the 1970s by the then Soviet Ivchenko-Progress design bureau. [2] It is manufactured by the Motor Sich factory in Zaporizhzhia , Ukraine . It was the first engine in the USSR that could deliver more than 20,000 kgf (~196 kN or ~44,000 lbf) of thrust. [ 3 ]
Produced by Volvo Aero, the RM12 is a derivative of the General Electric F404J. The fan was completely redesigned with thickened first stage blades which deform (causing the thrust loss) but do not fracture or cause downstream damage to pass more flow for higher thrust and to be more tolerant of a bird-strike.
