NK-8 and D-30 jet engines are early LOW-BYPASS Soviet turbofan engines for passenger jets, which were developed and used in 1960.
They're all low-bypass early turbofan engines developed by USSR in 1960s, with similar tech and performance with American JT3D and JT8D engines.
NK-8 and D-30 engines were used on Soviet 1970s jets, including Tu-134, Tu-154 and IL-62.
They've been replaced by better engines, such as AL-31 for military use, and PS-90 new generation high-bypass engines for subsonic aircrafts.
Nowadays, they're out-of-date after 60 years, like their American competitors, JT3D and JT8D engines.
In this thread, there're 1960s Early Soviet Turbofan tech Engine NK-8 and D30 maintenance manuals and illustrated parts catalogue ( IPC ).
