What engine is on the b787?
Rolls-Royce Trent 1000
The Rolls-Royce Trent 1000 is a high-bypass turbofan engine produced by Rolls-Royce plc, one of the two engine options for the Boeing 787 Dreamliner, competing with the General Electric GEnx.
What is the diameter of a 777 engine?
Massive General Electric turbofan on the Boeing 777-300ER This engine is the largest and most powerful turbofan built to date, being some 11 ft 3 in (3.43 m) in diameter.
What is Boeing equivalent thrust?
Note: Manufacturers often use their own arbitrary definitions of reference thrust. For example, the ‘Boeing Equivalent Thrust’ (BET) is defined as (sea-level ISA thrust at Mach 0.25) * 1.255. Such definitions are little more than rough ‘average’ thrusts for the takeoff run.
How much HP does a 747 have?
The power per engine for the two aircraft is seen to be 14 984 horsepower and 1646 horsepower for the 747 and Super Constellation, respectively….

How big is a 747 engine?
A Boeing 747 aircraft has a PW4000 engine with a 94 inch inlet diameter.
What kind of engine is the GEnx 2B?
Optimized for the Boeing 747-8 airplane, the GEnx-2B engine features a smaller fan, de-staged booster and de-staged low-pressure turbine. The GEnx-2B contains an identical core and similar materials as the GEnx-1B to provide synergies for mixed GEnx fleets.
How big is the fan on a GenX?
The 2,000th GEnx was delivered by November 2019, 15 years after the engine launch, as it logged 4.5 million flight cycles and 26 million hours among 60 operators. The GEnx is derived from the GE90 with a fan diameter of 111.1 in (282 cm) for the 787 and 104.7 in (266 cm) for the 747-8.
What are the advantages of the GEnx engine?
The GEnx engine represents a giant leap forward in propulsion technology, using the latest materials and design processes to reduce weight, improve performance and deliver a more fuel-efficient commercial aircraft engine.
Which is better GE CF6 or GEnx engine?
Based on proven GE90 architecture, the GEnx engine will offer up to 15% improved fuel efficiency and 15% less CO2 compared to GE’s CF6 engine.
