Tumansky RD-9B turbojet engine
Tumansky RD-9 was the first turbojet engine completely designed in USSR (previous engines were based on German and British designs). It was developed out of the Mikulin AM-5 with a new compressor with higher sub-sonic airflow. The engine completed testing in 1953 and qualifies for 5732 lb trust without afterburner. When Tumansky replaced Mikulin as the chief designer in the OKB in 1956, the engine was renamed RD-9.
[edit] RD-9 Versions
- RD-9A and RD-9AK - non-afterburning versions for Yak-25 and Yak-26
- RD-9AF-300 and RD-9AF2-300 - afterburning versions for Yak-27 and Yak-28
- RD-9B - afterburning version for early MiG-19
- RD-9BF-811 - afterburning version for late MiG-19
The RD-9B was also used in the civil east German jetliner project Baade 152 in 1958 and 1959. Here it was replaced when East German Pirna 014 engines were completed.
