The Tumansky R-29 is a Soviet aircraft turbojet engine that was developed in the early 1970s. It is generally described as being in the "third generation" of Soviet gas turbine engines which are characterized by high thrust-to-weight ratios and the use of turbine air cooling.
R-29-300 Original variant. Used in the MiG-23MF and related variants.
R-29B-200 Simplified variant of the engine intended for the MiG-27.
R-29PN Advanced variant that replaced the -300 model on non-export aircraft.
