Description |
The Sikorsky R-6 was a light two-seater helicopter produced for the US Air Force and Navy by the American Sikorsky Helicopter company. It took its first flight in 1943. It’s most well-known variant, the R-6 A is known as the Hoverfly II. The first prototype in the series, the XR-6, was powered by a Lycoming O-435-7 producing 225 horsepower.The R-6 was created as a direct upgrade to the highly successful Sikorsky R-4. The R-6 has a completely redesigned, streamlined fuselage and a longer tail boom, all changes aimed at improving on the flight performance of the R-4.The main-rotor and transmission systems as well as several other components were however retained from the R-4.The fuselage is all-metal and has a large engine than the R-4. In the R-6A that engine was the 240 horsepower (180 kW) Franklin 0-405-9 piston engine.In total 225 R-6 series helicopters were built since its creation. The main users of the R-6A were the Unites States Navy and the Royal Air Force (RAF). The first units were delivered to the Air Force in late 1944, from where some were transferred to the US Navy. Originally 150 R-6 helicopters were meant for the RAF, but production problems prevented the full number from ever reaching their destination. The Hoverfly II remained in service with the RAF until April 1951.
