The Bristol 192 Belvedere was a heavy tandem helicopter made by the Bristol Aircraft Company . After Westland took over the Bristol helicopter division in 1961, the machine was marketed as the Westland Belvedere .
development
Based on the 173 model , the Belvedere had two rotors connected by a long shaft so that the helicopter could continue to fly if one engine failed. The first prototype made its maiden flight on July 5, 1958. He still had three-bladed rotors made of wood, which were replaced by four-bladed metal rotors from the fifth prototype.
The Belvedere was originally intended as a ten-seat, fast liaison helicopter. The Royal Air Force was interested in a transport helicopter that could transport up to 18 fully equipped soldiers or two and a half tons of cargo and therefore initially ordered 22 machines. The order was later expanded to 26 belvederes . The machines were used in different units from 1961 to 1969. In addition to the 72nd Squadron in RAF Odiham , this also included squadrons overseas, the 26th Squadron in RAF Kormaksar and the 66th Squadron in RAF Seletar .
A civil version as an intercity shuttle aircraft for 23 passengers was planned, but was not built.
