This 3D model was originally created with Sketchup 13 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 whoever made the JT8D-17, I took the fan from that. I presume that there is an original author but I did not find him anywhere. Modeled entirely from scratch except the fan. The Pratt %26 Whitney JT8D is a low-bypass {0.96 to 1} turbofan engine, introduced by Pratt %26 Whitney in February 1963 with the inaugural flight of Boeing's 727. It was a modification of the Pratt %26 Whitney J52 turbojet engine, which powered the US Navy A-6 Intruder attack aircraft. The Volvo RM8 is an afterburning version that was license-built in Sweden for the Saab 37 Viggen fighter. A fixed version for powerplant and ship propulsion is known as the FT12. Eight models comprise the JT8D standard engine family, covering the thrust range from 12,250 to 17,400 pounds-force [62 to 77 kN] and power 727, 737-100/200, and DC-9 aircraft. More than 14,000 JT8D engines have been produced, totaling more than one-half billion hours of service with more than 350 operators making it the most popular of all low-bypass turbofan engines ever produced. The JT8D-15 was primarily used on the Dassault Mercure.
