We'll print custom logos and turbofan engine product documentation in your language, and provide spare parts for easily worn down components. We also can design and deliver OEM/ODM samples in one month.

The General Electric GE90-115B engine is an advanced ultra high bypass turbofan engine that was developed especially for the twin engine Boeing 777 airliner. The GE90 is the ultimate turbofan engine and holds the Guiness World Record for the most powerful engine in aviation for thrust production. The engine is rated for 115,000 lbs. of thrust, though on the test stand it has been run up to 127,900 lbs. of thrust to demonstrate the incredible peformance/reliability margin and the potential for future growth. The GE90 also holds the record for the highest pressure ratio of any aviation engine in the world at 45:1. That means that the engine's compressors compress atmospheric air to approximately 45 bar, or to 661 psi before feeding that high pressure air into the burner. Along with tremendous power, the GE90 is the most efficient engine in the sky, with specific fuel consumption rivaling that of a typical large Diesel engine.

The turbofan engine is the modern engine for fighter planes. How do they work? Well, here it is. When air goes into the engine, it gets compressed. Then it meets with the fuel and a combustion, or small explosion happens. That gives about 85% of the thrust. The other 15% is the air blown by the fan like a propeller. colors: green: fans. orange: air to be combusted. blue: air to be blown. light blue: core
red: fuel. purple: combustion chamber. The fan turns at a maximum speed of only 2,550 rpm, but flows enough air in doing so to make tremendous thrust. Air from the fan can follow one of two paths. A vast majority of it enters the bypass duct, and travels around the core of the engine where it is exhausted out of the rear to provide thrust. The engine features a 9:1 bypass ratio, so 9 times more air travels through the bypass duct than actually enters the core of the engine.
