The R27-300 engine, that is mounted on the MiG-23 PD and the MiG-23S gives 5,200 Kgf of thrust and 7,800 Kgf with afterburner. It is a turbojet of this well-known designer.

-It has compressor air bleeding that "blew" the flaps in certain maneuvers. (The MiG-23PD also had two Koliesov RD-36-35 engines for vertical lifting).

-The engines of the R-29 and R-35 families (in addition to the R-27) are also from K. Khachaturov.

-The R27F2M-300 delivered 6,900/10,000 Kgf.

-The R29-300 delivered 8,300/12,200 Kgf.

-The R-35-300 delivered 8,550/13,000 Kgf.

-Khachaturov was a Chief of Design within the Mikulin and Tumansky offices (Today Soyuz/Tumansky).

-Khachaturov and Koptchyenko have worked together on the R-79 vectored-thrust turbofan that gave 12,400 Kgf, and 15,500 Kgf with afterburner.

From Appendix 6: Seen in a confidential document - Recently declassified - on a Khachaturov R-35 engine on a Mig-23 aircraft.

“R-35 Engine Installation”

-The engines such as R-27, R-29, R-35 or R-79 (and R-179) are due to this designer.

-We know that in Russia there is the OKB design office that designed the engine. Another company carries out the project and prepares it for production, and finally “others” build it. Thus we have that the same engine is manufactured by several builder brands.

-Even other engineers appear who throughout the history of the engine are making improvements. This case.

-The engines known as Khachaturov R-29-300 and R-29B-300 are due to this constructor, and have been seen in certain MiG-23 series (M, MF, MS, BN, etc.) Both engines are very similar.

“R-29-300”

-Khachaturov collaborated with Tumansky. The R-35-300 is also an engine product of this collaboration.

“Khachaturov/Tumansky, R-35-300”

-This engine in particular is exhibited at the Luftfahrtmuseum in Rothenburg, Germany. The engine is based on the R-29-300.

From Appendix 9: Within the Soyuz (Union) company he collaborated with Tumansky.

-The R-27M-300 engines with 10000 Kgf of thrust are attributed to them for the MiG-23S.

-With Tumansky he collaborated on the R-35-300 for the MiG-23 MF, ML and MLD.

-The R-29B, BS and PN for the Su22, MiG-23MF and MiG-27 was also in collaboration with Tumansky.

The R-79 and R-179 are considered to be a collaboration between Khachaturov and Kobchyenko.
