General Electric GE90: Meaning (information, definition, explanation, facts)

General Electric GE90 is a family of high-bypass turbofan engines built by General Electric for the Boeing 777. It has thrust range between 74,000 to 115,000 lb (329 to 512 kN). It was first introduced in November 1995 on British Airways' 777. It is only available on the 777. The engine is one of three options for the 777-200, -200ER, and -300, and the exclusive engine of the -200LR and -300ER.

The GE90 are physically the biggest engines in aviation history. They are also the most powerful, as GE90-115B holds the world record for the biggest thrust rating, 127,900 lb (569 kN), though is rated at 115,300 lb (513 kN). The engine diameter is larger than that of a Boeing 737 fuselage.

They can only be airfreighted by Antonov An-124 Ruslan, presenting unique problems if a 777 is stranded due to emergency diversions. As a consequence, it incurs high preventive maintenance costs to minimise such risks.
