Russian manned spacecraft module. Operational. First launch 2002.10.30. Further improvement of Soyuz T PAO service module with pressure-fed main engines and unitary RCS/main engine propellant feed system. Equipment-engine section.
The new KTDU-80 propulsion system, developed from a NII Mash experimental thruster, included four spherical tanks with a total of 880 kg propellant. The variable thrust engine could achieve three different thrust levels through adjustment of four valves: 6000 N, 0.7 N, 0.3 N. Specific impulse varied from 326 - 286 sec according to setting.
RCS Coarse No x Thrust: 16 X 98 N. RCS Fine No x Thrust: 8 X 98 N. RCS Coarse Backup No x Thrust: No separate backup translation engines.. Electric System: 0.60 average kW.
