RD-0155 engine history
The engine RD-0244 (+4 x = RD-0245 RD-0243) is the main engine of the first stage of the SLBM R29RM (Shtil). It uses UDMH/N2/O4 as fuel.
This single-chamber RD-0244 engine was used as a demonstrator RD-0244KD in 1999 for the future dual-chamber engine RD-0155 on the basis of Kerosene/LOX.
Obviously, the new engine RD-0155 was tested in 2003 for the first time successfully.
This new engine consists of two chambers: A fixed inner chamber and a gimbaled outer chamber. Chamber pressure in the fixed chamber 180 kg/m2 (=17.65 MPa); in the gimbaled chamber 160 kg/m2 (=15.69 MPa).

Data:
Single-chamber engine RD-0244 (UDMH/N2O4): 618.3 kN (s.l.), 682.5 kN (vac), Isp 288.4/321.6 sec, mix 2.6, chamber pressure 275 at or kg/m2 (=26.97 MPa)
Demonstrator RD-0244KD (Kerosene/LOX): 689.4 kN (vac), Isp 332.3 sec (vac), mix 2.7, chamber pressure 235 at or kg/m2 (=23.05MPa)
Dual-chamber engine RD-0155K (Kerosene/LOX): 786.5 kN (s.l.), 881.6 kN (vac), Isp 297/333 sec, mix 2.6, chamber pressure 180 at or kg/m2 (=17.65MPa)
Dual-chamber engine RD-0155V (Kerosene/LOX): 929.2 kN (s.l.), 1098.3 kN (vac), Isp 291/344 sec, mix ?, chamber pressure ?
