More Than 750 GE90, GEnx Turbofans Ordered
General Electric told Aero-News Friday that 2005 has been a
record-breaking year of sales for GE's newest large commercial
engines, the GE90 and GEnx, with more than 750 engines ordered.
The GE90 engine family has sold more than 240 engines in 2005,
according to General Electric, including a record 225 of the higher
thrust GE90-115B engines. Boeing selected the GE90-115B engines as
the exclusive powerplants for the fast-selling 777-300ER, 777-200LR
and the 777 freighter. The value of the GE90 engines sold this year
exceeds $4.5 billion.
In its first year on the market, more than 525 GEnx engines have
been selected to power the Boeing 787 and 747-8, as well as the
Airbus A350. The GEnx engine is the best selling engine on the 787
and A350 aircraft and was selected by Boeing as the sole powerplant
for the recently launched 747-8 aircraft. The value of the GEnx
engines sold now exceeds $6 billion.
In 1995, GE introduced the GE90 series of engines into airlines
service, and the engines have logged more than 6.5 million flight
hours. The GE90-94B engine, in particular, has an outstanding
in-flight shutdown rate of 0.003 per 1000 engine flight-hours, well
below the current 180-minute ETOPS requirement of 0.020 per 1000
In 2004, the GE90-115B entered service on a Boeing 777-300ER
aircraft at an unprecedented 115,000 pounds (512 kN) thrust. To
date, the GE90-115B engine has completed more than 160,000 hours
and 22,000 cycles with no engine removals and no in-flight
shutdowns--a remarkable achievement for an entry into service of a
new jet engine. Delivery of the first 777-200LR aircraft is
scheduled for early 2006.
The GEnx is based on the architecture of the highly successful
GE90. It will succeed the CF6 engine family, which is GE's most
reliable and best-selling engine on wide-body aircraft.
The GEnx provides
significantly better fuel burn and payload performance than GE's
CF6 engines. It is the world's only jet engine with a front fan
case and fan blades made of composites, which provides for greater
engine durability, weight reduction and lower operating costs.
The fan blades will utilize GE90 composite technology that has
performed remarkably well on GE90 engines, with no in-service
issues for more than decade. The GEnx will operate with 18 fan
blades -- half the number of blades on the venerable CF6 -- at
noise levels lower than any large GE commercial engine currently in
service. The GEnx also features a new combustor for efficient fuel
mixing before ignition, resulting in significantly lower NOx
Testing on the GEnx engine for the Boeing 787 is scheduled to
start in early 2006, with engine certification planned for mid-2007
and entry into service scheduled for 2008.
The certification schedule for the GEnx engine for the A350
includes engine certification in 2007, flight tests in 2009 and
aircraft/engine certification in 2010.
