@Regranned from @popularmechanics - The GE9X, the biggest aircraft engine in the world (fan diameter: 11' 2' nacelle diameter: 14' 6') was recently mounted on GE's 747-400 flying testbed to begin flight tests before the end of the year. The engine will ultimately be used to power Boeing's 777X family. GE had to shift the engine forward and up to. The Boeing 777 is a large twin engine jet transport designed for regional and extended range service. The primary electrical system is a 3-phase, 4-wire, constant frequency 400 Hz, 115/200 Volt system, which has been the industry standard on commercial jet transports since the Boeing 707 (and maybe before, but that's as far back as I go). Boeing 777 Each engine on the 777 has a diameter approximately the size of a 737’s fuselage All of the engines on the Titanic delivered around 46,000 horsepower combined. Just one of the GE units on the 777 puts out over 111,000 horsepower During certification testing in 2002, the GE90-115B engine (777-300) set a world-record.

The GE90: A technology pioneer

In 1995, the GE90 debuted aboard a British Airways 777 aircraft, along with commercial aviation’s first ever carbon fiber fan blades.

The GE90 engine family powers all Boeing 777 models. It is the exclusive powerplant on the Boeing 777-300ER, -200LR, and Freighter. The engine has accumulated nearly 100 million flight hours and 14 million cycles since entering service.

Safran Aircraft Engines of France, Avio Aero of Italy and IHI Corporation of Japan are all revenue-sharing participants in the GE90 program.

Composite fan blade

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.

The GE90 fan blade’s uniquely curved design makes it larger, lighter and more aerodynamic than traditional titanium blades for reduced engine weight and lower fuel burn. Plus, the aerodynamic design allows the GE90 fan blade to pull large amounts of air into the engine, making it quieter and more efficient while generating unrivaled thrust.

A later variant, the GE90-115B fan blade, was introduced into New York’s Museum of Modern Art in 2007 as a perfect example of cutting-edge engineering, design and beauty.

Thrust

During certification testing in 2002, the GE90-115B engine set a world-record 127,900 lbs. of thrust. The GE90-115B ran for approximately 60 hours at triple red-line conditions (maximum fan speed, core speed and exhaust gas temperature) to evaluate the engine at its operational limits and demonstrate its capability beyond the most extreme operating conditions. It took GE another 15 years to break the record, which they did at 134,300 lbs. of thrust with the new GE9X engine.

TRUEngine designation for the GE90

Available for the GE90 engine family, the GE TRUEngine program helps operators maximize operational reliability by maintaining all engine components to GE maintenance standards and recommendations. The TRUEngine designation can also result in as much as 50% higher engine residual value and enable easier evaluation of engine configuration, asset value and market attractiveness.

The program is voluntary, there’s no cost to participate, the TRUEngine designation is fully transferrable, and operators can use any MRO shop for their overhauls.

GE90 Engine Models

GE90-94B Engine

Rated at 94,000 lbs. of thrust, the GE90-94B engine builds on the proven success of the early GE90 engine models and powers the Boeing 777-200 and 777-300 aircraft.

GE90-115B Engine

Boeing 777 Motor Price

After being selected by Boeing to develop an engine with 110,000 to 115,000 lbs. of thrust, GE delivered the GE90-115B engine, which now powers the longer-range Boeing 777-200LR, 777-300ER and 777 Freighter aircraft.
