Technology update
GE90-94B makes first Boeing 777 flight
-
The Boeing 777-200ER (extended-range) aircraft completed its first
flight with the new GE90-94B engine.
|
The Boeing Co. has successfully completed the first flight of a 777-200ER
airplane powered by two General Electric GE90-94B engines. The company
used an Air France 777-200ER as a test bed for
the engine test.
Rated at 94,000 lb of thrust, the GE90-94B builds on the proven success
of the GE90 engine family, adding performance-enhancing technologies
such as the 3-D aerodynamic high-pressure compressor - also a key
performance improvement being incorporated in the GE90-115B, which is
currently under development. "Performance-enhancing technologies built
into the GE90-94B will improve fuel burn on the 777 by more than 1%,
and improve exhaust gas temperature margins as much as 20°C," said Chaker
Chahrour, General Manager of the GE90 project.
The GE90-94B engines have completed more than 1400 h of
testing and received FAA flight test certification in June.
