At the weekend I was visiting an aviation museum, and in one of the exhibits was a photograph of a rather unique looking helicopter. The photo was taken at an airshow, and behind it was a Su-27. The helicopter also looked Russian.
The helicopter had a body similar to a chinook. It had two rotors, however unlike the chinook they were placed either side of the body on supports. Below each set of rotors where 2 sets of engine intakes, suggesting perhaps 4 engines total.
Does anyone know what kind of helicopter this was?
