Also in Poland we had a project of a helicopter with tandem rotors. In 1952-1953 a study of a helicopter designated GIL-3 (where "GIL" stood for "Główny Instytut Lotnictwa" or "Main Aviation Institute") was prepared. It was to have an engine developing 870 shp (the type had not been specified) and its payload should have been around 800 kg. No further works were undertaken however and the design team led by Bronisław Żurakowski concentrated on a single-rotor helicopter project, the GIL-4 that later became the BŻ-4 Żuk.

Best regards,
Piotr

Thanks for information Petrus, a totally new project to me.

Another family are the Filper Beta Models

Thanks also Martin, the Flippers are interesting because of their layout with the crew at the back.

Regards Bailey

My dear Bailey,

I have not tracked down an IH-50 as yet. AISA's projects are hard to get information on. Attached is a poor quality drawing of the IH-51, from the same source as the one of the IH-49 above.

Thanks for the Molyneux link.

Regards Bailey.

Rotorcraft XH-011 Dragonfly
which were all built

Depending on your definition, you could also include the Chrysler and Piasecki "flying jeep" designs with tandem shrouded rotors or even the Bensen prop copter.
