How much thrust does the GEnx produce?
The engine’s maturation program will accumulate more than 15,000 cycles by entry into service and 50,000 cycles total. With a range of thrust from 53,000 to 75,000 lbs, this GEnx engine will power all versions of the 787 Dreamliner with a common bill of material.
How much thrust does a 787 engine have?

How much thrust can a jet engine produce?
According to the Air Force, each engine can generate between 25,000 and 29,000 pounds of thrust. In this way, it can accelerate quickly even when climbing.
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.
What is the takeoff thrust rating of the genx1b?
57,400 lbf

How much thrust does a Dreamliner have?
Boeing 787 engines Boeing has selected two engine types, the General Electric GENX and the Rolls-Royce Trent 1000, each type developing 55,000lb to 70,000lb thrust. Each of the three planned 787 models uses the same engines. Both engines fit to a standard engine interface allowing interchangeability.
How much thrust does a mini jet engine produce?
Its advantage is its compact design, low weight with a thrust of up to 1,500 N, and low fuel consumption in the given power category.
At what Mach number is the highest specific thrust?
The highest burner exit temperature yields always the highest specific thrust. For the two lower Mach numbers of 1.2 and 1.8 a compressor pressure ratio of more than 30 yields the lowest specific fuel consumption. At the flight Mach number of 2.4 there is a SFC optimum with respect to pressure ratio around 20 to 22.5.
How much thrust does a GEnx engine produce?
The GEnx was expected to produce thrust from 53,000 to 75,000 lbf (240 to 330 kN) with first tests commencing in 2006 and service entry by 2008 (delayed by 787 deliveries). Boeing predicts reduced fuel consumption of up to 20% and significantly quieter engines than current turbofans.
What is a GE ENX engine?
The GEnx is the fastest-selling, high-thrust jet engine in GE Aviation history with more than 1,300 engines on order. In addition to powering the four-engine Boeing 747-8, the GEnx engine is also the best-selling engine for the Boeing 787 Dreamliner.
What is the difference between the GEnx and the Trent 1000?
The GEnx and the Rolls-Royce Trent 1000 were selected by Boeing following a run-off between the three big engine manufacturers. The GEnx uses some technology from the GE90 turbofan, including composite fan blades, and the smaller core featured in earlier variants of the engine.
What kind of engine does Boeing use in the GEnx?
The GEnx and the Rolls-Royce Trent 1000 were selected by Boeing following a run-off between the three big engine manufacturers. The GEnx uses some technology from the GE90 turbofan, including swept composite fan blades and the 10-stage HPC featured in earlier variants of the engine.
