Substitution of the similarly powered Avco Lycoming VO-435 resulted in the Model 47G-2 (H-13H). A 179kW VO-435 engine brought the changed designation Model 47G-2A, followed in 1963 by the wider cabin Model 47G-2A-1 with improved rotor blades and increased fuel capacity. Other engine installations included a 168kW supercharged Franklin 6VS-335-A (Model 47G-3); 209kW turbocharged Avco Lycoming TVO-435 (47G-3B); and normally aspirated Avco Lycoming VO-540 and VO-435 engines in the three-seat utility Model 47G-4 and Model 47G-5 re spectively. A two-seat agricultural version of the latter was known as the Ag-5, and a civil version of the USAF's H-13J VIP transport was marketed as the Model 47G-4 and Model 47G-5 respectively. ![]() Bell 47G-2 Wing Ding

In August 1964 it was reported that the British Army was buying 150 Bell 47G three-seat, similiar to the US Army OH-13S Sioux, but with 270 hp Lycoming TVO-435 engines. The first 50 were to be built in Italy by Agusta, and the next 100 by Westland Aircraft in Britain. The unit cost was about $50,000.
![]() 1959 Bell 47J
The 1959 version of the Bell 47J Ranger had a modified tail-rotor control to simplify maintenance. Larger drag-links are required for the metal blades of the main rotor. B 1959, over 2000 Bell 47s had been built.
The 47J "Ranger" is the first helicopter to have crossed the Andes by way of the Christo Paso. This flight was made at a height of 5180m, with a total weight of approximately 68kg below the helicopter's own maximum gross weight. HUL-1 is the U.S. Navy designation.
The Agusta-Meridionali EMA.124 Bell 47 derivative had three-seats, an open frame rear fuselage, skid u/c and one 305hp Textron Lycoming VO-540-B1B3 piston engine. Intended for production by Elicotteri Meridionali SpA, one prototype, I-EMAF, was built, first flown on 28 May 1970.
Kawasaki in Japan received a licence in 1953, and the Kawasaki-Bell 47G3B-KH-4 first flew as a type in 1962. Being a development of the Bell 47G3B by Kawasaki, the type features a four-seat cabin layout, modified instrument and control systems, and a 260 hp Lycoming.
