The Airbus A380 double deck airliner was first introduced in 2005. Passenger capacity for this massive jet liner is approximately 555 and it was designed to make the Boeing 747 obsolete. There are many model variants of the A380, and the engines are either Rolls-Royce Trent 900 series turbofans or Engine Alliance GP7000 turbofans.
General Trent 900 Specifications
The Trent 900 series turbofan engine is a three-stage high bypass ratio engine that is 179 inches long, and 116 inches in diameter. The dry weight for this engine is 6273kg. The thrust to weight ratio is 4.93-to-5.63, depending on the engine variant.
Trent 900 Variants Thrust Specifications
The Trent 970 has 31.8kgf (pound-force) of thrust and is used in the A380-841. A380-842 models use Trent 972 engines that produce 32.7kgf of thrust. The Trent 977 engines used in A380-843F produce 34.9kgf of thrust. Finally, Trent 980 engines used in A380-843F aeroplanes with higher thrust specifications, produce 36.3kgf of thrust.
General Engine Alliance GP7200 Specifications
The EA GP7200 engine is the engine line produced for the A380. GP7270 and GP7277 are the two main variants used in the Airbus A380.
