The Tumansky R-29 is a Soviet aircraft turbojet engine that was developed in the early 1970s.[1] 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.[2]
Variants
R-29-300 Original variant. Used in the MiG-23MF and related variants.[3]
R-29B-200 Simplified variant of the engine intended for the MiG-27.[3]
R-29PN Advanced variant that replaced the -300 model on non-export aircraft.[3]
R-29BS-300 Variant with modified gearbox. Used in several export variants of the Sukhoi Su-17.[3]
