Goto Bell Helicopters

he Bell 47 is a single rotor single engine light helicopter manufactured by Bell Helicopter. It was based on the third Bell 30 prototype, which was the company’s first helicopter designed by Arthur M. Young. The 47 became the first helicopter certified for civilian use on 8 March 1946.[1][2] The first civilian delivery was made on December 31, 1946 to Helicopter Air Transport.[3] More than 5,600 Bell 47s were produced, including those under license by Agusta in Italy, Kawasaki Heavy Industries in Japan, and Westland Aircraft in the United Kingdom

Design

Early models varied in appearance, with open cockpits or sheet metal cabins, fabric covered or open structures, some with four-wheel landing gear. Later model D and Korean War H-13D and E types settled on a more utilitarian style. The most common model, the 47G introduced in 1953, can be recognized by the full “soap bubble” canopy,[4] exposed welded-tube tail boom, saddle fuel tanks and skid landing gear.

The later three-seat 47H had an enclosed cabin with full cowling and monocoque tail boom. It was an attempt to market a “luxury” version of the basic 47G. Relatively few were produced.

Deployment

The “Telecopter” was a Bell Model 47 rented by television station KTLA in Los AngelesCalifornia. It was outfitted with a television camera and it made the worlds first flight by a television news helicopter on July 3, 1958, with its inventor, John D. Silva, aboard. When the television station reported it was receiving no video, Silva exited the helicoptercockpit to climb onto its landing skid while it hovered at 1,500 feet (457 m) so he could investigate the microwave transmitter bolted to its side, where he discovered a vacuum tube had failed due to vibration and hot weather. After Silva fixed the problem overnight, the Telecopter made the world’s first successful television news flight on July 4, 1958.
