Design

Bell 47J Ranger

Early models were variable in appearance, with open cockpits or sheet metal cabins, covered or open structures, some with four-wheel landing gear. Model D and Korean War types settled to a more utilitarian style. The most common model, the 47G introduced in 1953, can be recognized by the full bubble canopy, exposed welded-tube tail boom, saddle fuel tanks, and skid landing gear. Later 47H and 47J Ranger models had a regular cabin with full cowling and monocoque tail boom. Engines were Franklin or Lycoming horizontally-opposed piston engines of 200 to 305 HP (150 to 230 kW). Seating varied from two to four. Many are still in use as trainers and in agriculture (as of 2005).

Initially, the US Navy procured several Bell 47s, designated HTL-1, between 1947 and 1958. The US Coast Guard evaluated this model, and procured two HTL-1s for multi-mission support in the New York Harbor. The most common US Navy version of the 47 was designated the HTL-4, and dispenses with the fabric covering on the tail boom. The US Coast Guard procured three HTL-5s in 1952 (similar to the HTL-4 but powered by a Franklin 0-335-5 engine) and used these until 1960.^[3]

The Coast Guard procured two of Bell's Model 47G and designated them HUL-1G in 1959.^[3]

The British version of the 47G, called by the British Army the Sioux AH.1, was built by Westland Helicopters for use by the Army Air Corps, who used it until the early 1980s.^{[citation needed]} The Sioux military version was often equipped with military evacuation panniers, one to each skid, with an acrylic glass shield to protect the patient from wind.

Bell 47 redesignations

The Bell 47 was designated under multiple systems, see United States of America military aircraft designation systems. It is best known as the H-13 Sioux, though it actually started as the YR-13 in 1946. It became the H-13 under the USAF, though the USN had called it the HTL. The United States Military Aircraft Designation System was first designed in 1919 when the US Armys Aeronautical Division became the United States Army Air Service. ...

In post-1962 US designations combinations with the number 13 are often skipped, but in the older system the R-13/H-13 shared the number with the X-13 Vertijet and XP-13 Viper (see List of military aircraft of the United States) The Ryan X-13A-RY Vertijet, Ryan Model 69, was an experimental Vertical Take-Off and Landing aircraft flown in the United States in the 1950s. ... The XP-13 Viper was a prototype biplane fighter designed by the Thomas-Morse Aircraft Corporation and delivered to the United States Army in 1929. ... This list of military aircraft of the United States includes prototype, pre-production and operational types. ...

In 1962 Army, Navy, and Air Force versions were redesignated under the new Tri-service system. Mainly, the H-13 based ones were converted to new standards which included a vehicle type designator and a mission symbol (2 letter prefix; OH, UH, XH, etc. This was a shift from the initial USAF 1948 system (with the numbered carried over from the USAAF/C system) and the USN 1922-1962 system to the new 1962 system.^[8]
