This 3D model was initially developed using Sketchup 15 before being converted into multiple 3D formats. The native file format is .skp, while the 3ds Max 2016 version was rendered with Vray 3.00 for use on a Boeing 747-400. The model draws inspiration from Airbus A330's fan, original pylon, and materials. It also utilizes WilliamT's original 744 engine. Originally designed for L-1011-1, Rolls-Royce's RB211 engine was enhanced to provide greater thrust by redesigning the fan and IP compressor, reaching 50,000 lbf (220 kN). The upgraded version, designated RB211-524, launched on October 1, 1973, and powered new L-1011 variants as well as the Boeing 747. Despite failed attempts to sell the engine to Boeing in the 1960s, the -524 version offered significant improvements over the Pratt & Whitney JT9D, leading Boeing to offer the RB211-524 on the 747-200. British Airways was the first airline to order this combination, which entered service in 1977. Rolls continued to develop the -524, increasing thrust through the -524C (51,500 lbf/229 kN) and -524D (53,000 lbf/240 kN), certified in 1981. Notable airlines using this engine include Qantas, Cathay Pacific, Cargolux, and South African Airways. When the larger Boeing 747-400 was launched, additional thrust was needed, leading to the -524G (58,000 lbf/260 kN) and -524H (60,600 lbf). These were the first versions to feature FADEC, with the -524H also offered as a third engine choice on the Boeing 767. The first of these entered service with British Airways in February 1990.
