The BELL 47 Helicopter Family - Models A thru K
The Bell 47 went through many incarnations in it's illustrious history, fulfilling both civilian and military needs. My research is certainly not perfect but I have endeavored to be as accurate as I can. This page will be updated as needed over time. The production figures shown are for US models only. I hope you enjoy this brief basic rundown of the Bell 47 Helicopter family.

MODEL 30 : The Beginning
Bell's first helicopter was invented and built by Arthur Young. The Model 30 had a 2-bladed rotor with perpendicularly- mounted stabilizer bar. Without the bar, movement of the rotor mast, mounted directly to the rotors, would cause the plane of rotation of the rotors to change, thus producing instability. Centrifugal force of the stabilizer bar, linked directly to the rotor, isolated the rotor from the movement of the rotor mast which was attached to the rotor hub by a universal joint. Arthur Young's patent was later assigned to Bell Aircraft Company. In November 1941, Young joined Bell Aircraft and agreed to build 2 helicopters to demonstrate the concept. In December 1942, the first of 3 prototypes, Ship 1, was built at the Gardenville, NY plant. By July 1943, Ship 1 had reached speeds of over 70 mph. Soon after, Ship 1 was damaged during a power- off landing because of poorly designed landing gear. It was rebuilt as Ship 1A with raised a tail-rotor and modified landing gear to permit the aircraft to remain in nose-up position for power-off landings. Ship 2, a 2-passenger version with enclosed cockpit, became the next test vehicle. By 1944, the Model 30 was considered ready for public display and was featured in a Buffalo Sunday newspaper. In July of 1944, it made it's public debut before a crowd inside Buffalo Stadium.

In early 1945, work began on Ship 3 designed with the best elements of Ships 1 and 2. Four-wheel landing gear worked better on take-offs and landings, different body shape with the instrument panel in the middle and almost no floor gave unobstructed vertical vision, and later a bubble canopy gave undistorted vision. It launched on April 20, 1945 and was an immediate success. With room for 2 passengers, no obstructive body or windshield, and only a small instrument column between pilot and passenger, the pilot had uninterrupted view up and down. The Model 47, based on this design, made it's first flight on December 8, 1945. On March 8, 1946, it received CAA Type Certificate H-1 and was the first American commercial helicopter. The Bell 47 has since been produced by more countries than any other helicopter in the world.

The first Bell 47s led to the pre-production military Model 47A and then came the commercial Model 47B. Later came the 47B-3, 47D, 47D-1, 47E, 47G, 47G-2, 47G-3, 47G-4, 47G-5, 47H-1, 47J, and 47K, which includes scores of military designations.

MODEL 47 A / YR-13
Improvements and refinements to the pre-production Bell 47s led to the military Bell Model 47A (US Navy HTL-1, US Army Air Force YR 13). They were equipped with a 178 hp Franklin 6V4-178-B3 piston engine, 4 wheel landing gear, covered tail boom, optional two piece bubble, dual controls/pilot left side.

178 hp Franklin 6V4-178-B3 piston engine. Interestingly, Larry Bell did not like the bubble canopy and open tail boom. His vision was for the helicopter to look like a car. It was a bubble canopy version, however, where the Model 47 became the first commercially certified helicopter in the world, May 8, 1946.

Evolving from the B-3, the Model 47 D was equipped with a 200 hp Franklin O335-3 engine, 4 wheels landing gear until 1951 when they were replaced with the familiar skids setup. The 47D-1 came during production with a larger 3 person capacity cabin to compete against other helicopters looking for buyers. During the Korean war, someone thought of using the helicopter to lift wounded soldiers from the front lines and delivering them directly to the hospitals. This prompted the Army to order many more H-13s for years to come. The Army had a tradition to sometimes use the names of Native American tribes and the H-13s were named "Sioux". The name did not catch on all that well but the nickname "Angel of Mercy" certainly did as these ships ferried wounded troops to safety.The field hospitals were called MASH units, acronym for "Medical Army Surgical Hospital", and the H-13s became the image of Army aviation and troop rescue. Many will remember the scenes of the H-13s in the opening credits of the tv series, M*A*S*H.
The military 47D/H-13 models were as follows:

MODEL 47 G, G-2, G-3, G-4, G-5
The model 47G utilized all of the design improvements that had shown themselves from the years before. It was the first helicopter that was designed and built at the Fort Worth plant in Texas and was produced with constant improvements well into the 1970's. The 47G also was the first 47 design to be produced outside the United States. In 1954, Augusta in Italy began producing Bell 47s under license until 1979. Other countries to do so were Kawasaki in Japan from 1954 to 1976, and Westland in England from 1965 to 1969. Through this time period, the 47G is most recognizeable from earlier models by the dual saddle gas tanks, curved lower cabin opening, and rear synchronized elevator at the rear of the tail boom. The 47G became famous as the helicopter flown in the late 50s television show, Whirlybirds, along with it's 47J sister ship, and made the Bell 47 helicopter an American icon.

MODEL 47 H Bellairus
Introduced in 1955, this was a deluxe version of the 47G. It had a 200hp Franklin 6V4-200-C32AB engine, fully clad fuselage and an enclosed sound-proofed cabin which could accommodate one pilot and two passengers, modified landing skids, and contoured 35 US gallon fuel tanks. The cabin had leather upholstery throughout as well as a leather covered dashboard grouping all electrical controls. There was a luggage compartment in the metal switches and carburetor enclosed tail attempt to sell a luxury type helicopter for government boom section. This was an dignitaries and result was too small of an interior to adequately serve the businessmen. The end purpose for which it was intended.
