2 page booklet for ultralight helicopter XROE 1.


The Hiller ROE Rotorcycle was a single-seat ultralight helicopter designed in 1953 for a military requirement.[1] A total of 12 were produced for the United States Marine Corps. And in 1954, the Hiller Helicopters was selected by the US Navy`s Bureau of Aeronautics to build this design of a one-man, foldable, self-rescue and observation helicopter.[2] It featured a two-blade rotor system. Its original empty weight was 290 lb (132 kg).[3]
Development

The helicopter folded up and could be carried on a sled-like carrier by two people or could be air-dropped to pilots trapped behind enemy lines. The Marines did not accept the YROE due to its low performance, vulnerability to small-arms fire and the lack of visual references on the structure. This problem could cause the pilot to experience spatial disorientation at all but very low altitudes.[1] The YROE or ROE never saw military service.[4]

In 1954, the United States Navy′s Bureau of Aeronautics selected Hiller to build its proposed design of a one-man helicopter. The XROE Rotocycle completed flight testing in mid-1957.[5]

It was demonstrated at the Pentagon in Arlington, Virginia, for military and other government officials in early April 1958.[6]

Production was by Saunders-Roe, which made five for the United States Marine Corps and five for Helicop-Air of Paris.[7]

A Porsche engine of 62 hp (46 kW) developed for the YROE completed trials by 1961.[8]
