The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777, with thrust ratings from 81,000 to 115,000 pounds-force (360 to 510 kilonewtons).
Derived from the General Electric GE90 with a larger fan, advanced materials like ceramic matrix composites (CMCs), and higher bypass and compression ratios, it was designed to improve fuel efficiency by 10% compared to the GE90. It is rated at 110,000 lbf (490 kN) of thrust, which is 5,000 lbf (20 kN) less than the GE90 highest thrust variant ...
GEnx on 747-8I prototype. As of 2016, 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, [1] including swept composite fan blades and the 10-stage high-pressure compressor (HPC) featured in earlier variants of the engine.
* Note: two versions: one contained a 16-cylinder 7HDL, co-developed by GE and the German firm Deutz-MWM, rated at 6000 HP; the other a 16-cylinder 7FDL rated at 4390 HP. The units equipped with the 7FDL were a sub-version AC6000 "Convertible" and were produced to get the type into operation while the 7HDL was developed.
The General Electric CF6, US military designations F103 and F138, is a family of high-bypass turbofan engines produced by GE Aviation. Based on the TF39, the first high-power high-bypass jet engine, the CF6 powers a wide variety of civilian airliners. The basic engine core also powers the LM2500 and LM6000 marine and power generation turboshafts.
However, the GE/PW engine increased its share of the A380 engine market to the point where, as of September 2007, it will power 47% of the super-jumbo fleet. This disparity in sales was resolved in a single transaction, with Emirates ' order of 55 GP7000-powered A380-800s, comprising over one quarter of A380 sales (as of September 2007).
N747GE is a Boeing 747 aircraft that was used by General Electric Aircraft Engines (now known as GE Aerospace) as a testbed for several of the companies jet engines between 1992 and 2017, including the GE90 for the Boeing 777, at the time, the world’s largest jet engine.
The 280 cm (110 in) fan has 26 wide chord titanium fan blades. [10]The Trent 800 is an axial flow, high bypass turbofan with three coaxial shafts. The fan is driven by a 5-stage axial LP turbine (3300 rpm), the 8-stage IP compressor (7000 rpm) and the 6-stage HP compressor (10611 rpm) are each powered by a single stage turbine.
