This 3D model, initially developed using Sketchup 8, has been converted to various 3D formats. The native file format is .skp. It was designed for application on Boeing 747-400 and made use of materials from Airbus A330, including a fan, pylon, and original materials. Additionally, it utilizes an engine originally created by WilliamT for the 744 model. The RB211 engine was initially designed for L-1011-1 but was later enhanced to provide greater thrust through redesigns of its fan and IP compressor, increasing its power to 50,000 lbf (220 kN). This led to the development of the RB211-524 version that debuted in October 1973. Rolls-Royce offered this engine for the Boeing 747, and British Airways was the first airline to order it. The -524C increased thrust further to 51,500 lbf (229 kN), followed by the 53,000 lbf (240 kN) -524D certified in 1981. Notable airlines that utilized this engine include Qantas, Cathay Pacific, Cargolux, and South African Airways. In response to the requirement of more thrust for the Boeing 747-400, Rolls-Royce introduced the -524G with 58,000 lbf (260 kN) and later the -524H with 60,600 lbf (FADEC-equipped). The -524H was also offered for the Boeing 767, with the first one entering service in February 1990.
