The original R179-300 was developed for the Yak-41 and was considerably weaker than this. The improved variant proposed for the S-32 had a specified reheat thrust of 20000 kg or so, but there is no proof that this engine ever made it beyond the concept stage. For the eventuel S-37 Sukhoi opted for the same AL-41F engine as used by/proposed for the MiG MFI. This was the only new engine that progressed to the prototype stage. At the end only the 1.44 and flying testbeds were fitted with this engine. To cut it short a paper project isn’t of relevance here.
Yak-141, R79-300 power 15500 kg
Yak-41M, R79M-300, power 17500 kg
S-37 and T-60S bomber / “izd.54S” R179-300 power 21000 kg.
WK-21 for easy supersonic passenger aircraft, without afterburner, power 12000 kg.
WK – 21 Conversion engine version R179 – 300 without afterburner. Power – 12000 kgs. Bypass ratio m = 0,81. Is almost identical consumption on two types of cruising flight regimes – subsonic and supersonic. Promising for use on supersonic passenger aircraft, a new generation with a takeoff weight of 40 to 110 tons.
WC-21 and R-179-300 showed one or two times in the show “Motor” in Moscow. No other information.
