A.M. Isayev KTDU-35 spacecraft propulsion system
A.M. Isayev KTDU-35 was the integrated main propulsion system for Soyuz spacecraft. NASA identifies KTDU-35 as the main propulsion system and describes the related SKDU assembly as a primary S5.60 engine with a backup S5.35 engine; this record preserves the integrated-system boundary and does not create separate component-engine identities.
