7 September 1965: First flight of the prototype Bell Model 209 attack helicopter. Test pilot William Thomas (“Bill”) Quinlan was in command. The duration of the flight was twelve minutes.

The Model 209 was a private venture, built in just seven months and rolled out at Fort Worth, Texas, 2 September 1965. The prototype aircraft combined the drive system, rotors and tail boom of the production UH-1C gunship with a streamlined fuselage which placed the two pilots in tandem.

The prototype was equipped with retractable landing gear which gave the 209 increased speed, but the expense and complexity were enough that this feature was not included on production aircraft.

This helicopter would be developed into the famous AH-1G Huey Cobra.

The second prototype, AH-1G 66-15246, was used by the Army for flight testing at Edwards Air Force Base, California, from 3 April to 21 April 1967.

66-15246 had an overall length of 52 feet, 11.65 inches (16.146 meters) with rotors turning. The fuselage was 44 feet, 5.20 inches (13.433 meters) long, and it was 3 feet, 0 inches (0.914 meters) wide. The HueyCobra had a short “stub wing” with a span of 10 feet, 11.60 inches (3.343 meters). Its angle of incidence was 14°. The wing’s area was 27.8 square feet (2.6 square meters). 66-15426 had an empty weight of 5,516 pounds (2,502 kilograms) and maximum gross weight of 9,500 pounds (4,309 kilograms).

The two-bladed Model 540 “door-hinge” main rotor was 44 feet, 0 inches (13.411 meters) in diameter. The blades had a chord of 2 feet, 3 inches (0.686 meters) and 10° negative twist. The main rotor turned counter-clockwise when viewed from above. (The advancing blade is on the helicopter’s right.) Normal rotor r.p.m. (power on) was 314–324 r.p.m., and power off, 304–339 r.p.m. The minimum transient rotor speed, power off, was 250 r.p.m.

The two blade tail rotor assembly had a diameter of 8 feet, 6 inches (2.591 meters) with a chord of 8.41 inches (0.214 meters). There was no twist. It was mounted on the left side of the pylon in a pusher configuration and turned counter-clockwise as seen from the helicopter’s left. (The advancing blade is above the axis of rotation.) The tail rotor pylon was cambered to allow aerodynamic forces in forward flight to “unload” the tail rotor.

The AH-1G was powered by a Lycoming LTC1K-4 (T53-L-13) turboshaft engine rated at 1,400 shaft horsepower, though it was derated to the helicopter’s transmission limit. The T53-L-13 is a two-shaft free turbine with a 6-stage compressor (5 axial-flow stages, 1 centrifugal-flow stage) and a 4-stage axial-flow turbine (2 high-pressure stages, 2 low-pressure power turbine stages). The T53-L-13 is 3 feet, 11.9 inches (1.217 meters) long, 1 foot, 11.0 inches (0.584 meters) in diameter and weighs 549 pounds (249 kilograms).

The speed of the Cobra was effected by the armament configuration, whether “clean,” light or heavy scout, or “heavy hog.” At 5,000 feet (1,524 meters), the cruise speed in the clean configuration was 138.0 knots (158.8 miles per hour, 255.6 kilometers per hour); light scout, 134.0 knots (154.2 miles per hour, 248.2 kilometers per hour); and heavy hog, 127.0 knots (146.2 miles per hour, 235.2 kilometers per hour). The maximum airspeed in level flight was 149.0 knots (171.5 miles per hour, 276.0 kilometers per hour); 144.0 knots (165.7 miles per hour, 266.7 kilometers per hour); and 136.5 knots (157.1 miles per hour, 252.8 kilometers per hour), respectively.

The limiting airspeed (VNE) was 190 knots (KCAS) (219 miles per hour, 352 kilometers per hour) below 3,000 feet (914 meters) density altitude.

In autorotation, the airspeed for the minimum rate of descent was 74.0 knots (85.2 miles per hour, 137.1 kilometers per hour) with the main rotor turning 294 r.p.m., resulting in a rate of descent of 1,750 feet per minute (8.89 meters per second).

The basic armament for the AH-1G Cobra was an Emerson M28 turret which could be equipped with one or two General Electric M134 Miniguns, or a combination of a Minigun with a Philco Ford M129 automatic grenade launcher, or two grenade launchers. Each Minigun was supplied with 4,000 rounds of 7.62 NATO ammunition, while a grenade launcher had 300 rounds of 40 × 53 millimeter high-velocity explosive ammunition.

Four hardpoints on the stub wing could be loaded with M18 7.62 NATO Minigun pods; XM35 pods, containing a short-barreled General Electric XM195 20 millimeter Gatling gun (a variant of the M61 Vulcan); rocket pods with seven or nineteen 2.75-inch unguided rockets.

The prototype Cobra, Bell Model 209 N209J, is in the collection of the U.S. Army Aviation Museum, Fort Rucker, Alabama, as is the second prototype, 66-15246.

27 August 1990

Bell 206B JetRanger N16933, destroyed on impact, 27 August 1990. All five aboard, including famed guitarist Stevie Ray Vaughan, were killed. (NTSB)

27 August 1990: Four Bell JetRanger helicopters operated by Omniflight Helicopters Inc., arrived at a golf course near Elkhorn, Wisconsin, to pick up various musical artists after a concert at the Alpine Valley Music Theater and to return them to Chicago. They departed at 0040 hours, CDT.

The number three helicopter, Bell JetRanger III (Model 206B-3) serial number 2338, civil registration N16933, was piloted by Jeffrey William Brown of East Chicago, Indiana.

A last minute addition to the passenger complement was electric blues guitarist Stevie Ray Vaughan. Another passenger, Vaughan’s brother, Jimmie Vaughan, switched places with him and boarded a different aircraft.

A first-quarter Moon rose at 12:12 a.m. CST. It was very dark, with thick, patchy fog. The temperature/dew point spread was such that the pilots had to continually wipe heavy condensation from the windshields. Another of the Omniflight pilots later said that the stars were visible when looking up, but that horizontal visibility was variable, with a maximum of about one mile.

Brown, who was not familiar with the area, took off and after about 300 yards, his helicopter banked sharply to the southeast and disappeared into the fog.

The JetRanger impacted a 150-foot hill (45 meters), 0.6 miles away (1 kilometer). It was completely destroyed. All on board were killed. In addition to Brown and Vaughan, the others were Bobby Brooks, Nigel Browne and Colin Smythe, members of Eric Clapton’s tour.

Although the weather was such that the pilot could have reasonably expected to encounter instrument meteorological conditions, Brown did not have an Instrument-Helicopter rating and the Bell 206-series helicopters were not certified for instrument flight.

Below is the accident summary from the National Transportation Safety Board:

NTSB Identification: CHI90MA244 .

13 August 1976: At the Bell Helicopter facility at Arlington, Texas, the prototype Model 222 twin-engine helicopter, registration N9988K, made its first flight. During the 42-minute flight, test pilots Donald Lee Bloom and Louis William Hartwig flew the aircraft through a series of hovering maneuvers and transitions to forward flight. A Bell spokesperson described it as, “One of the most successful prototype flights we’ve ever had.”

The Model 222 (“Two Twenty-Two”) was Bell Helicopter’s first completely new helicopter since the Model 206 JetRanger series. Classified as a light twin, the aircraft was originally powered by two Lycoming LTS101-650C-3 turboshaft engines. The two-blade main rotor was similar in design to that used on the AH-1 Cobra attack helicopters. The first four prototypes were built with a T-tail configuration, but problems discovered early in the test program resulted in a change to the arrangement used in the production version.

The Bell 222 is used as an executive transport, a utility transport and an aeromedical helicopter. It can carry a maximum of ten persons, and is operated with either one or two pilots. The 222 is certified for Instrument Flight Rules. The standard aircraft has retractable tricycle landing gear but the Model 222UT replaces that with a lighter weight skid gear.

The Bell Model 222 is 47 feet, 6.16 inches (14.482 meters) long with rotors turning. The helicopter has a maximum height of 14 feet, 7.25 inches (4.451 meters) with the forward main rotor blade against its droop stop. The height from ground level to the top of the vertical fin is 11 feet, 0.56 inches (3.367 meters). The helicopter’s maximum width is 11 feet, 4.0 inches (3.454 meters). The empty weight is 4,555 pounds (2,066 kilograms), and the maximum gross weight is 7,848 pounds (3,560 kilograms).

The 222’s main rotor mast is tilted 5° forward and 1° 15′ to the left. This contributes to a higher forward air speed and counteracts the helicopter’s translating tendency in a hover.

The two-bladed, underslung, semi-rigid main rotor system rotates counter-clockwise as seen from above (the advancing blade is on the right.)and turns 324 r.p.m at 100% NR. The main rotor has a diameter of 39 feet, 9.0 inches (12.116 meters). The blades have a chord of 2 feet, 4.6 inches (7.264 meters) and are pre-coned 3° 30′. The two-bladed tail rotor is positioned on the left side of the tail boom and turns clockwise as seen from the helicopter’s left (the advancing blade is below the axis of rotation). The tail rotor’s diameter is 6 feet, 6.0 inches (1.981 meters). The blades’ chord is 10.0 inches (0.254 meters).

The Bell 222 was originally powered by two Lycoming LTS101-650C-3 engines. The LTS101 is a compact, light weight, turboshaft engine. The 2-stage compressor section has 1 axial-flow stage and 1 centrifugal-flow stage. The turbine section has 1 high-pressure gas generator stage and 1 low-pressure free power stage. The LTS101-650C-3 was has a maximum continuous power rating of 598 shaft horsepower (446 kilowatts at 49,159 r.p.m. (N1) at Sea Level, and 630 shaft horsepower (470 kilowatts) at 49,638 r.p.m. for takeoff (5-minute limit). The output shaft (N2) turns 9,545 r.p.m. With one engine inoperative (OEI), the -650C-3 is rated at 650 shaft horsepower (485 kilowatts) at 50,169 r.p.m. (30-minute limit), and a maximum 675 shaft horsepower at 50,548 r.p.m. N1/9,784 r.p.m. N2 (2½-minute limit). The LTS101-650C-3 is 1 foot, 10.6 inches (0.574 meters) in diameter, 2 feet,7.3 inches (0.795 meters) long, and has a dry weight of 241 pounds (109 kilograms).

The Bell 222 has a maximum speed of 130 knots. Its hover ceiling is approximately 9,000 feet (2,743 meters). The service ceiling is 12,800 feet (3,901 meters). The maximum range is 324 nautical miles (373 statute miles/600 kilometers).

During early production, problems were experienced with the LTS101 engines, which were also used on the Sikorsky S-76 and the Aérospatiale AS-350D A-Star. This seriously hurt the reputation and sales of all three helicopters. Bell Helicopter’s parent corporation, Textron, bought the Lycoming factory and modernized it in order to improve the engine. (The engine is now owned by Honeywell Aerospace.) Operators began to replace the two Lycoming engines with a pair of Allison 250-C30 turboshafts, and eventually Bell Helicopter modified the aircraft, marketing it as the Model 230. A four-bladed variant with a longer cabin is called the Model 430.

After the test program was completed, the first prototype, N9988K, was used as a static prop on the popular television series, “Airwolf.”

Donald Lee Bloom

Donald Lee Bloom was born in Tulsa, Oklahoma, 23 April 1932. He was the son of Fred Miles Bloom, a telegraph operator for the Standard Oil Company, and Georgia Randolph Bloom.

Don Bloom attended the University of Houston as a Naval Reserve Officers Training Corps (NROTC) midshipman. He graduated in 1955. Bloom was commissioned as a second lieutenant, United States Marine Corps, 15 September 1955. He was assigned to pilot training at NAS Pensacola, Florida.

Lieutenant Bloom was promoted to the rank of first lieutenant, 15 March 1957. He married Miss Anne Marie Carruthers in Los Angeles, California, 5 September 1958. They would have four children, Susan, Stacy, Robert and Todd.

Lieutenant Bloom was released from active duty in 1960, and joined the Kaman Aircraft Corporation as a test pilot. In 1961, began his 29-year career as an experimental test pilot with the Bell Helicopter Company.

In 1984 the Society of Experimental Test Pilots gave its Iven C. Kincheloe Award to Don Bloom for his experimental research into the Loss of Tail Rotor Effectiveness (LTE).

After flying as a test pilot on 187 projects, Don Bloom retired from the Bell Helicopter Corporation in 1990 as Senior Experimental Test Pilot. He then worked for the Federal Aviation Administration Southwest Region as its Designated Engineering Representative Flight Test Pilot, testing aircraft for government certification. During his aviation career, Bloom flew over 14,000 hours in 102 different aircraft.

In 2011, the Federal Aviation Administration presented its Wright Brothers Master Pilot Award to Don Bloom.

Donald Lee Bloom died 18 July 2017 at Grapevine, Texas. He was buried at the Dallas-Fort Worth National Cemetery, Dallas, Texas.

Louis William Hartwig was born at Sherman, Iowa, 26 July 1922. He was the son of Lawrence C. Harwig and Alta May Gaughey Hartwig. He attended Bowie High Schoo in Bowie, Texas.

Lou Hartwig enlisted in the United States Army 8 September 1942. (s/n 17119277) He was assigned to the 304th and 902nd Field Artillery Battalions, 77th Infantry Division.

Lou Hartwig married Miss Katherine Elizabeth Healzer, a school teacher, at Rustburg, Virginia, 19 February 1944. They would have a son, Ronald.

Hartwig was deployed to the Pacific theater of operations, 24 March 1944. He flew a Piper L-4 Grasshopper as an artillery spotter at Guam and Okinawa. He was discharged from his enlistment 18 June 1944, and commissioned a second lieutenant, 19 June 1944 (s/n O-1821011). Lieutenant Hartwig returned to the United States on 21 November 1945. He was released from active duty 24 January 1946.

Lou Hartwig was one of the early students of the Bell Aircraft Corporation’s helicopter flight school at Niagara Falls Airport, New York. The school was for experienced pilots only, and required 10–15 days to complete. Each student received a minimum 22½ flight hours in a Bell Model 47. The cost of the course was $600. Hartwig was then employed as an agriculture “crop dusting” pilot in California.

While spraying insecticide in a field near Sacramento, California, Hartwig was overcome by the poisonous chemicals and lost consciousness. The helicopter struck power lines and crashed. Hartwig was thrown from the cockpit. Crash investigators described the accident as “unsurvivable.” He spent the next 11 months in hospital.

Lou Hartwig was a test pilot for the U.S. Navy’s HSL-1 ASW helicopter. (Bell Aircraft Corporation)

The Bell Helicopter Company hired Hartwig as a test pilot on 15 February 1955. One of his first projects was flight testing the Model 61, the only tandem rotor helicopter ever produced by Bell. It was used as an anti-submarine warfare helicopter by the U.S. Navy, designated HSL-1.

On 31 January 1961, Hartwig set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers Without Payload, when he flew a Bell Model 47J Ranger at an average speed of 168.36 kilometer per hour (104.61 miles per hour).¹

On 2 February 1961, Lou Hartwig flew a Bell Model 47G, N967B, to set three more FAI world records: Distance in a Closed Circuit Without Landing, 1,016.20 kilometers (631.44 miles); ² Speed Over a Closed Circuit of 500 Kilometers Without Payload, averaging 119.07 kilometers per hour (73.99 miles per hour); ³ and Speed Over a Closed Circuit of 1,000 Kilometers, 118.06 kilometers per hour (73.36 miles per hour.⁴ The Model 47G had been modified with an additional fuel tank from the earlier Model 47D-1, and curved landing skids from the Model 47J.

1 August 1977: Francis Gary Powers, a pilot and news reporter for KNBC Television (Channel 4) in Los Angeles, California, was flying the company’s “Telecopter,” a camera and transmitter-equipped Bell Model 206B Jet Ranger, N4TV. He and a cameraman, George R. Spears, had been reporting on the aftermath of the disastrous Sycamore Canyon Fire in Santa Barbara County and were returning to their base, the KNBC Heliport at the television studios near the Ventura Freeway in Burbank.

At approximately 12:35 p.m., PDT, (19:35 UTC), the JetRanger was eastbound, about 1 mile southwest of Van Nuys Airport (VNY). Powers called Van Nuys Tower and requested to land there as the helicopter was low on fuel. The last transmission was: “TV Four just lost—”

Francis Gary Powers was a highly-experienced airplane pilot. At the time of the crash, Powers had 7,193 total flight hours, with 381 hours in the Bell 206. He had attended the Bell 206B Pilot Transition Training Course at the Bell Helicopter Training School, Fort Worth, Texas.

When TDiA attended the Bell Helicopter Training Academy in 1981, the crash of Power’s JetRanger was discussed by the school’s instructors in great detail. The high-profile accident involving Bell’s leading civil product had been thoroughly investigated by the National Transportation Safety Board (NTSB) and by Bell’s own experts.

(TDiA requested the official NTSB accident investigation report nearly three years ago, and though the request received immediate acknowledgement, the report has not yet been provided.)

Powers, returning from covering the fire in Santa Barbara for Channel 4 News, flew past the Santa Barbara Municipal Airport (SBA), Oxnard Airport (OXR), and Camarillo Airport (CMA), all of which were almost directly along his course, and all of which could have provided fuel for the Bell 206.

Powers passed those airports, but just a few miles short of his destination, 1 mile (1.6 kilometers) to the southwest of Van Nuys Airport (VNY), the busiest general aviation airport in the United States, the helicopter’s turboshaft engine stopped because of fuel starvation. The JetRanger crashed in an open field. Both Powers and his cameraman, George Robert Spears, were killed.

Examination of news photographs of the wreck show that the JetRanger was completely destroyed on impact. It appears to have struck the ground in a nose-down attitude. Surprisingly, damage to the main rotor assembly is slight, with no twisting, tearing, or failure of the doublers at the blade root, as are commonly seen.

An engine failure over a large, level open space, should have resulted in no damage to the aircraft or injuries to its occupants. The autorotation characteristics of the Bell 206-series helicopters are excellent, among the best of any helicopter. The extent of the damage to the airframe, though, when compared to the relatively slight damage to the main rotor assembly, convinces TDiA that the helicopter was not in autorotation, but in free fall. The main rotor blades were not turning within the autorotation r.p.m. range of 355–440 r.p.m.

There are reports that Powers turned the helicopter away from a group of children playing in the open field, but this would not have been possible with the main rotor turning at the very low rotational speeds demonstrated by the lack of twist damage.

Francis Gary Powers at Milligan College, 1949.

Francis Gary Powers was born 17 August 1929 in Letcher County, Kentucky. He was the son of Oliver Windfield Powers, a mortarman in the coal industry, and Ida Melinda Ford Powers.

Powers attended Milligan College at Elizabethton, Tennessee, from 1947 to 1950. He studied biology. He was a member of the school’s pre-med club, and was junior class manager of the intramural council. He was also on the varsity track team.

Francis Gary Powers entered United States Air Force in 1950, trained as a pilot and was commissioned in 1952. He flew the Republic F-84G Thunderjet fighter bomber with the 468th Strategic Fighter Squadron, 506th Strategic Fighter Wing, at Turner Air Force Base, Albany, Georgia. He received special training in delivery of the Mark 7 tactical nuclear weapon at Kirkland Air Force Base, Albuquerque, New Mexico.

In 1956, 1st Lieutenant Powers was released from the U.S. Air Force to participate in the Central Intelligence Agency’s Project Aquatone. He was now a civilian government employee, although he was promised that he could return to the Air Force and that he would keep his seniority and would be promoted on schedule.

Francis Gary Powers gained world-wide notoriety when the Lockheed U-2A he was flying,  “Article 360,” (USAF serial number 56-6693) was shot down over Russia, 1 May 1960. Powers was captured and held prisoner at the notorious Lubyanka Prison where he underwent 62 days of interrogation at the hands of the Komitet gosudarstvennoy bezopasnosti (the Committee for State Security, or simply, the KGB). Powers was placed on trial in Moscow and was convicted of espionage. He was sentenced to prison for ten years.

After almost two years, he was exchanged for William August Fisher, (AKA Rudolf Ivanovich Abel, Vilyam Genrikhovich Fisher) a long-time Soviet intelligence officer that had been caught in the United States in 1957. [This story was recounted in the recent motion picture, “Bridge of Spies,” which starred Tom Hanks. The film received six Academy Award nominations in 2015.]

After his release from the Soviet Union, Powers was employed as a test pilot for Lockheed, 1962–1970. He then became an airborne traffic and news reporter for several Los Angeles-area radio and television broadcast stations.

Gary Powers and his first wife, Barbara Gay Powers, divorced in 1963. He then married Claudia Edwards Downey at Fauquier, Virginia, 26 October 1963. This was also her second marriage. They would have a son, Francis Gary Powers II. (Mrs. Barbara Powers remarried in 1964.)

On 24 November 1986, the Distinguished Flying Cross was awarded posthumously to Powers “For Extraordinary Achievement While Participating in Aerial Flight 1 May 1960.” After reviewing his record at the request of his son, Francis Gary Powers, Jr., on 15 February 2000, the U.S. Air Force retroactively promoted him to the rank of Captain, effective 19 June 1957, and further credited his military service to include 14 May 1956–1 March 1963, the time he was with the CIA. The award of the Prisoner of War Medal was also authorized.

On June 15, 2012, General Norton Schwartz, Chief of Staff of the Air Force, awarded Captain Francis Gary Powers the Silver Star (posthumous).

George Robert Spears was born at Chicago, Illinois, 17 July 1934, the fourth of five children of William E. and Nora Neelom Spears. He married Annette A. Montalbano in Chicago, 26 May 1956. They had three children and lived at Northridge, California. He had worked for KNBC since June 1976.

N4TV was built as a Bell Model 206A JetRanger, serial number 433, at Hurst, Texas, in 1969. It was first owned by the Los Angeles, California, independent television station KTLA (Channel 5), and registered N555TV. The helicopter was later upgraded to the Model 206B standard with the installation of a more powerful Allison 250-C20 engine. When purchased by KNBC, a National Broadcasting Company affiliate, 433 was reregistered N4TV.

The Bell Model 206B JetRanger is a 5-place, single-engine, light civil helicopter based on Bell Helicopter Company’s unsuccessful OH-4 entrant for the U.S. Army’s Light Observation Helicopter (LOH). It is flown by a single pilot in the right front seat. Dual flight controls can be installed for a second pilot. The helicopter is 39 feet, 8 inches (12.090 meters) long, with rotors turning. On standard skid landing gear, the overall height is 9 feet, 4 inches (2.845 meters). The main rotor has a diameter of 33 feet, 4 inches (10.262 meters) and turns counterclockwise (as seen from above) at 394 r.p.m. (100% NR). The empty weight is approximately 1,700 pounds (771 kilograms), depending on installed equipment, and its maximum gross weight is 3,200 pounds (1,451.5 kilograms).

The 206A was powered by an Allison 250-C18 turboshaft engine rated at 370 shaft horsepower at 6,016 r.p.m., and derated to 317 s.h.p., the transmission’s limit. The later 206B and 206B-2 had a 400 horsepower 250-C20 engine, and 206B-3s had 250-C20B, -C20J or -C20R engines installed, which produced 420 shaft horsepower. The helicopter’s transmission, however, is limited to 317 horsepower input.)

The JetRanger has a maximum speed of 150 miles per hour (241 kilometers per hour). Its best rate of climb is at 60 miles per hour (97 kilometers per hour) and best glide distance is at 80 miles per hour (129 kilometers per hour). The service ceiling is 13,500 feet (4,115 meters) and maximum range is 430 miles (692 kilometers).

Note: The Model 206A-1 was adopted by the U.S. Army as the OH-58A Kiowa. Though very similar in appearance to the Model 206A and 206B, the OH-58A differs significantly. Few of the parts are interchangeable between the types.

Between 1967 and 2010, Bell Helicopter built 4,491 JetRangers and 2,275 OH-58 Kiowas. Nealy 1,000 more were built under license by other manufacturers.

12 July 1957: President Dwight D. Eisenhower was the first United States president to fly in a helicopter when a U.S. Air Force H-13J-BF Sioux, serial number 57-2729 (c/n 1576), flown by Major Joseph E. Barrett, USAF, departed the White House lawn for Camp David, the presidential retreat in the Catoctin Mountains of Maryland. Also on board was a U.S. Secret Service special agent. A second H-13J, 57-2728 (c/n 1575), followed, carrying President Eisenhower’s personal physician and a second Secret Service agent.

The helicopter was intended to rapidly move the president from the White House to Andrews Air Force Base where his Lockheed VC-121E Constellation, Columbine III, would be standing by, or to other secure facilities in case of an emergency.

Major Barrett had been selected because of his extensive experience as a combat pilot. During World War II, he had flown the B-17 Flying Fortress four-engine heavy bomber. During the Korean War, Barrett had carried out a helicopter rescue 70 miles (113 kilometers) behind enemy lines, for which he was awarded the Silver Star.

The two helicopters were manufactured by the Bell Helicopter Company at Fort Worth, Texas, and delivered to the Air Force at Wright-Patterson Air Force Base on 29 March 1957. The presidential H-13Js were nearly identical to the commercial Bell Model 47J Ranger. The H-13J differed from the civil Model 47J by the substitution of main rotor blades of all-metal construction in place of the standard laminated wood blades.

Capable of carrying a pilot and up to three passengers, the Ranger was constructed with an enclosed cabin built on a tubular steel framework with all-metal semi-monocoque tail boom. The main rotor diameter was 37 feet, 2.00 inches (11.328 meters) and tail rotor diameter was 5 feet, 10.13 inches (1.781 meters), which gave the helicopter an overall length of 43 feet, 3¾ inches (13.185 meters) with rotors turning. The height (to the top of the centrifugal flapping restraints) was 9 feet, 8 inches (2.946 meters). The helicopter had a maximum gross weight of 2,800 pounds (1,270 kilograms).

The main rotor, in common to all American-designed helicopters, rotates counter-clockwise as seen from above. (The advancing blade is on the helicopter’s right.) The anti-torque (tail) rotor is mounted to the right side of an angled tail boom extension, in a tractor configuration, and rotates counter-clockwise as seen from the helicopter’s left. (The advancing blade is above the axis of rotation.)

The main rotor is a two-bladed, under-slung, semi-rigid assembly that would be a characteristic of helicopters built by Bell for decades. The main rotor system incorporates a stabilizer bar, positioned below and at right angles to the main rotor blades. Teardrop-shaped weights are placed at each end of the bar, on 100-inch (2.540 meters) centers. The outside diameter of the stabilizer bar is 8 feet, 6.781 inches (2.611 meters). (A similar system is used on the larger Bell 204/205/212 helicopters.)

The H-13J was powered by an air-cooled, normally-aspirated 433.972-cubic-inch-displacement (7.112 liter) AVCO Lycoming VO-435-A1B (O-435-21) vertically-opposed 6-cylinder direct-drive engine. The VO-435 had a compression ration of 7.3:1. It was rated at 220 horsepower at 3,200 r.p.m., maximum continuous power, and 260 horsepower at 3,200 r.p.m. for takeoff. The VO-435-A1B weighed 393.00 pounds (178.262 kilograms).

Engine torque is sent through a centrifugal clutch to a 9:1 gear-reduction transmission, which drives the main rotor through a two-stage planetary gear system. The transmission also drives the tail rotor drive shaft, and through a vee-belt/pulley system, a large fan to provide cooling air for the engine.

Fuel was carried in two gravity-feed tanks, mounted above and on each side of the engine. The total fuel capacity was 34.0 gallons (128.7 liters)

Cruise speed for the H-13J was 87–98 miles per hour (140–158 kilometers per hour), depending on gross weight, and its maximum speed was 105 miles per hour (169 kilometers per hour). The helicopter had a hover ceiling in ground effect (HIGE) of 8,100 feet (2,469 meters). The service ceiling was 15,000 feet (4,572 meters).

Both H-13J Sioux served as presidential aircraft until 1962. They were redesignated UH-13J and continued in use for VIP transportation until 1967.

Bell UH-13J-BF Sioux 57-2729 is in the collection of the Smithsonian Institution National Museum National Air and Space Museum, Steven V. Udvar-Hazy Center, while its sister ship, 57-2728, is at the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio, along with Columbine III.
