Yakovlev Yak-60

From Wikipedia, the free encyclopedia

This article is about a conjectural designation for a helicopter project. For the Yakovlev izdeliye 60 (изделие, "item") reconnaissance drone, see Yakovlev Pchela.

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]

Development

This helicopter was designed in the late 1960s, and may have been a competing design to the Mi-12 heavy lift helicopter. 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 conventional, 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]
