Bell H-13 Sioux#Operators

{{Expand section|Fill in some details on early development|date=March 2009}}

In 1947, the United States Army Air Forces (later the United States Air Force) ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux.Donald, David, ed. "Bell Model 47". The Complete Encyclopedia of World Aircraft. Barnes & Nobel Books, 1997. {{ISBN|0-7607-0592-5}}.

Initially, the United States Navy procured several Bell 47s, designated HTL-1, between 1947 and 1958. The United States Coast Guard evaluated this model, and procured two HTL-1s for multi-mission support in the New York Harbor. The most common U.S. Navy version of the 47 was designated the HTL-4, and dispenses with the fabric covering on the tail boom. The U.S. Coast Guard procured three HTL-5s in 1952 (similar to the HTL-4 but powered by a Franklin O-335-5 engine) and used these until 1960.{{cite book |last=Pearcy |first=Arthur |title=A History of Coast Guard Aviation |publisher=Naval Institute Press |year=1989 |isbn=0-87021-261-3}} The Coast Guard procured two of Bell's Model 47G and designated them HUL-1G in 1959.

The H-13 was one of the principal helicopters used by the U.S. Army during the Korean War, with the H-13D variant being the most prevalent. During the war it was used in a wide variety of roles including observation, reconnaissance, and medevac. From its role in medevac flights, it gained the nickname "Angel of Mercy". It was also used as an observation helicopter early in the Vietnam War, before being replaced by the Hughes OH-6 Cayuse in 1966.

The Bell 47 was ordered by the British Army as the Sioux to meet specification H.240, with licensed production by Westland Helicopters. In order to comply with the terms of its licence agreement with Sikorsky Aircraft, which prevented it building a U.S. competitor's aircraft, Westland licensed the Model 47 from Agusta, who had purchased a license from Bell.{{harvnb|James|1991|p=55}} the first contract was for 200 helicopters. The first 50 helicopters of the contract were built by Agusta at Gallarate in Italy followed by 150 built by Westland at Yeovil. The first Westland Sioux made its maiden flight on 9 March 1965.

The Sioux is a single-engine, single-rotor, three-seat observation and basic training helicopter. In 1953, the Bell 47G design was introduced. It can be recognized by the full "soap bubble" canopy (as its designer Arthur M. Young termed it),{{cite AV media |people=Arthur M. Young |title=Arthur Young on the Helicopter (Part 2) |medium=YouTube |language=en |url=https://www.youtube.com/watch?v=zrH3rU8lL3Q |archive-url=https://ghostarchive.org/varchive/youtube/20211215/zrH3rU8lL3Q |archive-date=2021-12-15 |url-status=live|access-date=April 8, 2016 |format=YouTube |time=10:15 to 11:45 |publisher=Arthur M. Young |quote="I thought the bubble was a great idea, and we tried it. 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." }}{{cbignore}} exposed welded-tube tail boom, saddle fuel tanks and skid landing gear. In its UH-13J version, based on the Bell 47J, it had a metal-clad tail boom and fuselage and an enclosed cockpit and cabin.

The H-13 and its military variants were often equipped with medical evacuation panniers, one to each skid, with an acrylic glass shield to protect the patient from wind.

The development of the Sioux was helped greatly by Bell's implementation of a short weighted gyro-stabilizer bar at 90° beneath and to the main rotor. It had streamlined counterweights at both tips and was linked so it determined which plane the rotor was in and kept it horizontal.{{Cite web |title=Bell-H13-Sioux {{!}} Aircraft {{!}} |url=http://www.fiddlersgreen.net/models/aircraft/Bell-H13-Sioux.html |access-date=2024-09-11 |website=www.fiddlersgreen.net}} The stabilizer, which was connected to the cyclic pitch control, acted as a hinged flywheel using gyroscopic inertia to keep the rotor blades in plane and independent of fuselage movement due to wind. It ensured that the system had enough inertia due to flight as well, so autorotation would function in case of engine failure.{{Cite web |title=Bell-H13-Sioux Aircraft|url=http://www.fiddlersgreen.net/models/aircraft/Bell-H13-Sioux.html |access-date=2024-09-11 |website=fiddlersgreen.net}}

A single 260 hp Lycoming VO-435 piston engine was fitted to the 47G variant. Fuel was fed from two high-mounted external tanks. A single two-bladed rotor with short inertial stabilizing minor blades was used on the Sioux.{{cite web |url=http://www.helis.com/database/model/277/ |title=westland sioux — Helicopter Database |access-date=2009-01-17}}

;YR-13:{{efn|In the military of the United States, the Bell 47 carried several designations prior to 1962. R-13 was the first designation by the United States Army Air Forces, while the Navy designated their training version as HTL. In 1948, the United States Air Force changed the designation to H-13 which was also adopted by the Army, adding the name Sioux. The Navy and Coast Guard designated utility models as HUL. In 1962, under a joint designation system created by the Department of Defense, the designations for all of the helicopters were changed to a mission symbol followed by the vehicle type designator creating a two-letter prefix (OH, UH, XH, etc.), but the Bell 47 retained its original series number, 13 and the Army's popular name. To denote different models, a letter suffix was appended to the designation.{{cite web |url=http://www.personal.psu.edu/users/d/o/dob104/aviation/us/index.html |title=U.S. Military Aircraft and Weapon Designations |author=Derek Bridges |access-date=2007-04-17 |archive-url=https://web.archive.org/web/20070306101712/http://www.personal.psu.edu/users/d/o/dob104/aviation/us/index.html |archive-date=6 March 2007 |url-status=dead }}}} 28 Bell 47A helicopters procured by the United States Army Air Forces for evaluation.

The H-13 has appeared, and played key roles, in many film and television productions. It has been associated with both the M*A*S*H TV series (1972–1983) and the film of the same name (1970), prominently featuring the H-13 in its opening credits, and played a central role in the series finale, which still holds the

record as the highest rated single episode broadcast in America.{{cite web |title=Top 100 Rated TV Shows Of All Time |url=https://tvbythenumbers.zap2it.com/reference/top-100-rated-tv-shows-of-all-time/ |website=TV by the Numbers |access-date=April 1, 2020 |archive-url=https://web.archive.org/web/20200319070342/https://tvbythenumbers.zap2it.com/reference/top-100-rated-tv-shows-of-all-time/ |archive-date=March 19, 2020 |date=March 21, 2009 |url-status=dead }}{{cite news| url=http://content.usatoday.com/communities/thehuddle/post/2010/02/saints-win-in-super-bowl-xliv-scores-highest-tv-ratings-since-1987/1 | work=USA Today | title=Saints' win over Colts in Super Bowl XLIV is most-watched television program ever | date=February 8, 2010}} The series helped popularize the H-13 as the helicopter most people now associate with the Korean War.{{cite web |last1=Hughes |first1=Kaylene |title=Army helicopters in Korea, 1950 to '53 |url=https://www.army.mil/article/177302/army_helicopters_in_korea_1950_to_53 |website=army.mil |access-date=1 July 2021}} The H-13 also played a key role in the Whirlybirds TV series (1957–1959).{{cite web |url=http://www.rotaryaction.com/m.html |title=M*A*S*H |publisher=rotaryaction.com |access-date=6 April 2016 |archive-url=https://web.archive.org/web/20160310172708/http://www.rotaryaction.com/m.html |archive-date=10 March 2016 |url-status=dead }}{{cite web|url=http://www.rotaryaction.com/pages/whirlybirds.html|title=Whirlybirds|publisher=rotaryaction.com|access-date=12 April 2016|archive-url=https://web.archive.org/web/20160313123735/http://www.rotaryaction.com/pages/whirlybirds.html|archive-date=13 March 2016|url-status=dead}}
