What is the weight of a 777 engine?
Two engines are available for some 777s: Rolls-Royce and GE. These each have a “wet” installed weight and a “dry” installed weight, which you can get from the manufacturer’s sites. Refer to Tom Stagliano’s approximations; the GE90 weighs between 17,400 lb (7,893 kg) and 19,316 lb (8,762 kg).

How much does a 747 engine weigh in pounds?
The 747-100B has four engines, and for this little exercise, we will assume it is fitted with Pratt & Whitney JT9D-7A turbofans, which weigh in at 8,850 lb each, for a total of 35,400 lb.
Why are 777 engines so big?
The reason why: the new engines offer far greater fuel efficiency and much less noise thanks to composite 3D printed materials and larger fan blades. By reducing weight with previously unattainable materials, the engines are able to draw more air, which greatly improves the efficiency and noise part.
What is the weight of plane?
This includes the weight of the plane, which is about 41,000 kg (90,000 lbs), and the weight of the fuel which is about 18,000 kg (40,000 lbs). This leaves about 20,000 kg (45,000 lbs) for passengers, cargo, and crew.
How much does aircraft oil weigh?
Unless the specific weight for an item is known, the standard weights used in aircraft weight and balance are as follows: Aviation gasoline 6 lb/gal. Turbine fuel 6.7 lb/gal. Lubricating oil 7.5 lb/gal.
