- Yakovlev Yak-60
Yakovlev Yak-60 is a conjectural designation for a Soviet tandem-rotor heavy-lift helicopter design of the late 1960s. This designation has been suggested by noted aviation author
Bill Gunston based on the fact that an extant study model has the number "60" painted prominently on its side.It was planned to use four 6,500shp
D-25VF engines, each pared in tandem with rotors from theMil Mi-6 . The aircraft is said to have a cockpit similar in layout to that of theYak-24 and have over four times the payload of the Boeing-Vertol Chinook. The Yak-60 never made it to mockup stage and only a model exists.References
