This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 Thanks to Maberick Mocha, AirbusA330, WilliamT, and me of course.While the 747-100, which was powered by Pratt %26 Whitney JT9D-3A engines, offered enough payload and range for US domestic operations, it was marginal for long international route sectors. The demand for longer range aircraft with increased payload quickly led to the improved −200, which featured more powerful engines, increased MTOW, and greater range than the −100. A few early −200s retained the three-window configuration of the −100 on the upper deck, but most were built with a ten-window configuration on each side. The 747-200 was produced in passenger {−200B}, freighter [−200F], convertible {−200C}, and combi [−200M] versions. The 747-200B was the basic passenger version, with increased fuel capacity and more powerful engines; it entered service in February 1971. In its first three years of production, the −200 was equipped with Pratt %26 Whitney JT9D-7 engines {initially the only engine available}. Range with a full passenger load started at over 5,000 nmi [9,300 km] and increased to 6,000 nmi {11,000 km} with later engines. Most −200Bs had an internally stretched upper deck, allowing for up to 16 passenger seats.
