Top 15 things about World Largest Engine GE 9x for Boeing 777x

1.Crafting the GEnx jet engine is something of a puzzle—around 75,000 parts must come together just right to build the final product.

2. GE 9x Developed primarily for the new Boeing 777X, this behemoth is wider than the fuselage of a 737 jet and can generate more than 100,000 pounds of thrust

3. This giant orb controls the wind intake during simulations of engine distress. Called the turbulence control structure (TCS), it’s 30,000 pounds of aluminum and stainless steel.

4. Each of GE jet engines undergoes approximately 150 hours of simulated testing.

5. GE 9x undergone rigorous testing to simulate real world conditions, from frightening sand storms to ice slabs as thick as cutting boards.

6. The GE90 is the most powerful jet engine in the world, with the quietest rumble of any engine in its thrust class. Acoustic panels installed in the engine’s fan case, pictured here, help reduce its noise signature.

7. One of the ways we test whether a  jet engine is sturdy enough for flight is by putting it through rigorous testing to simulate real world conditions, from frightening sand storms to ice slabs as thick as cutting boards. Here’s a look at the GEnx engine installed for testing at GE facility in Winnipeg.

8. A look inside our  jetengine testing facility in Peebles, Ohio, where the walls of each of our testing cells are at least 20 feet thick. Built from special high-density concrete, made by vibrating the wet concrete down to squeeze out air and get rid of any weak spots, these testing cells are strong enough to simulate extreme conditions for GE jet engine.

9. The General Electric GE9Xis a high-bypass turbofan aircraft engine under development by GE Aviation for the Boeing 777X. Derived from the GE90

10. The first engine to test (FETT) completed its first test run in April 2016. With 375 cycles and 335 test hours.

11. GE 9x has the largest front fan at 134 inches in diameter with a composite fan case and 16 fourth generation carbon fiber composite fan blades

12. The GE9X went through icing tests in winter 2017. The FETT was finally used for 50 cold weathertest points such as ground fog or natural icing conditions,

13. The initial 777X flight-test engines will be shipped later in 2018 for an initial 777-9 flight in early 2019.

14. In 1995, the GE90 engine debuted aboard a British Airways 777 airplane along with commercial aviation’s first-ever carbon-fiber composite fan blades. Early GE90 engine models boasted outputs between 74,000 and 94,000 lbs. of thrust, and today it remains the world’s largest turbofan engine.

15. With the GE90, GE introduced the composite fan blade—the first-ever in commercial aviation. Measuring more than four feet long and weighing less than 50 pounds, the GE90 fan blade is made from carbon fiber and a toughened epoxy matrix that delivers double the strength and one-third the weight of titanium.
