Bell 47

May 20, 2023

This article is about the civil versions and operators of the Bell Model 47. For the military versions and operators, see Bell H-13 Sioux.

The 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 31 December 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. The Bell 47J Ranger is a modified version with a fully enclosed cabin and tail boom.

Design and development

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.

Engines were Franklin or Lycoming vertically mounted piston engines of 178 to 305 HP (150 to 230 kW). Seating varied from two (early 47s and the later G-5A) to four (the J and KH-4).

In April 2011 there were 1068 registered with the Federal Aviation Administration in the United States[5] and 15 in the United Kingdom.[6]

Bell 47s were produced in Japan by a Bell and Kawasaki venture; this led to the Kawasaki KH-4 variant, a four-seat version of the Model 47 with a cabin similar to the Bell 47J. It differed from the "J" in having a standard uncovered tail boom and fuel tanks like the G series. It was sold throughout Asia, and some were used in Australia.

In February 2010, the Bell 47 type certificates were transferred to Scott's Helicopter Services.[7] The sister company that was formed, Scott's - Bell 47, is in the process of starting production of a turboshaft powered version of the Bell 47, the 47GT-6, using a Rolls-Royce RR300 engine and with composite rotor blades, with deliveries planned from 2016.[8]

Operational history

 
Bell 47J Ranger

The Bell 47 entered US military service in late 1946, and operated in a variety of versions and under different designations for three decades. It was designated H-13 Sioux by the US Army, and during the Korean War, it served a variety of roles, including reconnaissance and scouting, search and rescue, and medevac.

The "Telecopter" was a Bell Model 47 rented by television station KTLA in Los Angeles, California. It was outfitted with a television camera and it made the world's 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 helicopter's cockpit 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.[9]

The National Aeronautics and Space Administration (NASA) had a number of Bell 47s during the Apollo program, used by astronauts as trainers for the lunar lander. Apollo 17 commander Eugene Cernan had a nearly disastrous crash into the Indian River in Florida in 1971, before his flight to the moon.[10] The 47 has also served as the helicopter of choice for basic helicopter flight instruction in many countries.

Records

  • 13 May 1949, a Bell 47 set an altitude record of 18,550 feet (5,650 m).[11]
  • 21 September 1950, first helicopter to fly over the Alps.[11]
  • 17 September 1952, Bell pilot Elton J. Smith set a world distance record for piston helicopters of 1,217 miles (1,959 km) by flying nonstop from Hurst, Texas, to Buffalo, New York.[11] As of 2018, this record still stands.[12]

It consisted of taking a large sheet of Plexiglas, and a plywood form, cut for the final dimension for the outside of the bubble, then heating the Plexiglas, putting it under the plywood form, letting air pressure come up through the middle, and it would blow just like a soap bubble. And, then we had a gauge saying how far to blow, and when it reached that point, we turned off the air pressure.
