Tumański RD-9B

Country:USSR
Type:jet engine
Year:

A single-flow, single-shaft turbojet engine with a nine-stage axial compressor. It features a system controlling air bleed from the fifth compressor stage depending on its compression ratio. From the compressor, the air flows to ten combustion chambers housed in a common casing.

The two-stage axial gas turbine is followed by an afterburner chamber with a hydraulically regulated nozzle. The engine was developed in the early 1950s at the Mikulin Design Bureau as a lightweight, high-thrust powerplant for fighter aircraft.

It was also produced in the People’s Republic of China. It was used in the MiG-19S, MiG-19P, MiG-19PM and Yak-25 aircraft.

Technical data:

Maximum thrust without afterburner2600 kG
Maximum thrust with afterburner3250 kG
Cruising thrust1750 kG
Fuel consumption1470 kg/h at cruising thrust
