|Bell Model 47J|
Proposed in 1956, the Model 47J was a four-seat utility version of the Model 47G. The 47J was powered by a 220hp derated Lycoming VO-435. The enclosed cabin had accommodation for the pilot seated centrally in front and three passengers on a cross bench aft. This bench could be removed to allow the installation of two stretchers. The port door could also be removed to permit the use of an internal electrically-powered hoist for rescue missions. Alternative skid or pontoon landing gear could be fitted and metal rotor blades were optional permitting a loaded weight of 1290kg. Larger capacity fuel tanks (182 litres) could also be installed providing an extended range of 400km. This model was also built under licence by Agusta with 152 aircraft built.

This is a modified Model 47G with a cabin for four persons: the pilot in front, and three passengers behind on a bench. The latter could be removed to make room for two stretchers and a detachable tip-up seat for a nurse. Among the fittings is an electric winch for use in rescue work. All the mechanical parts are the same as in the 47G-2.
One noteworthy feature is that the soldered-tube tail is replaced in the 47J by a monocoque beam. The central section is still made of tubes, but it is now streamlined, which makes this the second streamlined commercial model launched by Bell.
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.
