allllllllrighty, then! I got bored and decided to start on my United heavies build. the reason why there's black paint on the 747 is because I decided to possibly build it with the windows open. I may change my mind. and I had forgotten to do the 777's inside black, again, I may not do the windows open. dunno what I was thinking. guess I just wanted something to do, and didn't care how I did it. lol. but anyways. some days you just get bored and do little things to other kits like assemble the wings or fuselage and stuff. lol
The engines on this 777 and 747 are both Pratt Whitney PW4000s. the reason they're different sizes is because they're of different models. the engines on the 747 are the PW4056, and the ones on the 777 are PW4090. correct me if I'm wrong. hehe. the 747 engines were made by Contrails, and the 777 engines were made by Bra.Z.
The PW4000 is divided into three distinct families based on fan diameter.
The first family is the 94 inch (2.4 m) diameter fan with certified thrust ranging from 52,000 to 62,000 lbf (230 to 275 kN). It powers the Airbus A310-300, A300-600 aircraft, Boeing 747-400, 767-200/300 and McDonnell Douglas MD-11 aircraft and is certified for 180-minute ETOPS if used in twinjets. These models include the PW4052, PW4056, PW4060, PW4062, PW4062A, PW4152, PW4156A, PW4156, PW4158, PW4460, and PW4462.
The second family is the 100 inch (2.5 m) diameter fan engine developed specifically for Airbus Industrie's A330 twinjet. It has certified thrust from 64,500 to 68,600 lbf (287 to 305 kN). Models are numbered PW4164, PW4168, and PW4168A. The launch of the Advantage70 program was announced at the 2006 Farnborough Airshow with a sale to Kingfisher Airlines.[1] This package will increase certified thrust to 70,000 lbf (311 kN,) reduce fuel burn by about 1%, and reduce maintenance costs by around 15%.[2]
The third family is the 112 inch (2.8 m) diameter fan engine developed specifically for Boeing's 777 where it was the launch engine. It has certified thrust from 86,760 to 99,040 lbf (386 to 441 kN). Model numbers are PW4074, PW4077, PW4077D, PW4084, PW4084D, PW4090, and PW4098. It entered service in June 1995 with United Airlines, and was the first jet engine to enter service with 180-minute ETOPS certification. It can power all the 777 versions except the 300ER and 200LR.
The PW4000 features advanced technology materials and Full Authority Digital Engine Control (FADEC), for good fuel economy and reliability.
