Yakovlev Yak-60 is the possible designation for an experimental Yakovlev tandem-rotor heavy-lift helicopter design of the late 1960s. This design never progressed beyond the model stage.[1]
This heilocopter was designed in the late 1960s, and may have been a competing design to the Mi-12 heavy lift heilocopter. It featured two Mi-6 rotors in tandem, each driven by a pair of 6,500shp D-25VF engines, potentially giving it four times the payload capacity of the Boeing-Vertol Chinook. The cockpit would have been similar to that of the Yak-24. Compared to the radical Mi-12, the Yak-60 design was far more convential, though ultimately two Mi-12s were produced.[1]
The designation Yak-60 has been suggested based on an extant study model which has the number "60" painted prominently on its side.[1]
