777X DELAY

ON ENGINE ISSUES

A

pair of the engines were installed on the airframe

and started on May 29, but during the test, “an

engine gave us a signal about its health. We had an

anomaly in the compressor and we halted the run,”

GE’s Ted Ingling said in an interview.

The issue was with the engine’s 11-stage high-

pressure compressor section, but has nothing to do with overall

performance. “It is not an aerodynamic issue whatsoever.” said

Ingling.

The 777-9, which incorporates technology from the 787 and offers

greater cabin width and seating capacity, was scheduled to start its

flight test regime earlier this year. But launch customer Emirates

Airlines reports that the first flight has been pushed back until at least

end June. GE and Boeing agreed that the engines will be modified

before attempting the first flight.

GE says the GE9X engine is the most efficient turbofan it has

ever produced, with a 10 percent lower fuel burn over the GE90-

115B that powers the 777-300ER. The engine has the largest diameter

fan section GE has ever attempted, but with only 16 4th-generation

composite blades. It has an overall engine pressure ratio of 60 to 1, the

highest of any engine yet produced, according to GE.

THE LONG-AWAITED FIRST FLIGHT OF

BOEING’S 777X WILL BE DELAYED

FURTHER THANKS TO PROBLEMS WITH

THE AIRCRAFT’S GE9X ENGINES.

The GE9X engine is the biggest turbine engine in the

world, here being installed on the 777X for its flight test.

Aircraft Headsets

For over 50 years, Peltor has led development in protec-

tion and communication for anyone who spends time in

noisy environments. All headsets in the Aviation 8000

series have ambient noise compensated differential

microphones. The earphones have a broad frequency

range for good sound reduction in Fixed Wing Aircraft and

Helicopters.

Ground Power Unit

You can depend on Hobart for full support of your aircraft’s

power requirements AC or DC. Hobart has earned the rep-

utation of being the “standard” in the industry, trusted for

the superior power quality and excellent durability.

The Red Box RB Series

These man-portable GPU’s use the latest in dry lead acid

military / aviation technology which offers many valuable

features. Very rugged, they can be operated, stored

or transported in any orientation, even inverted. Safely

transported in aircraft, land or sea, they produce massive

power for comparatively low weight and small size. They

hold their charge for long periods when on standby or in

storage.

Eagle Tow Tug

Nothing moves you like an Eagle tug. Designed and built

to meet the varying demands of regional airlines, corporate

fl ight departments and military fl ight ops. The Eagle TT

series All-Wheel Drive aircraft tractors pack a lot of power

in a small package. The advantage of All Wheel Drive

provides safe controlled traction on all surface conditions.
