Engine Developed For The Dreamliner Approved For Extended Twin
Engine Operation
The Trent 1000 engine, developed for the Boeing 787 Dreamliner
by Rolls-Royce, has been granted Extended Twin Engine Operations
(ETOPS) approval by the FAA. This important milestone means that
the Trent 1000 is the first engine for the 787 to have ETOPS
certification, a critical step towards entry into service.
ETOPS regulations cover the design, specification and operation
of twin engined aircraft on routes where an aircraft will be more
than one hour's flying time on one engine from a suitable and
available airfield. The Trent 1000 has been granted 330 minutes
ETOPS approval. This allows more direct routings, shorter flight
times and thereby reduced fuel consumption.
Rolls-Royce has now delivered Trent 1000 engines to Boeing to
support 787 Dreamliner test flights for ETOPS approval of the
engine/aircraft combination. At the same time, the company has
delivered engines for the first All Nippon Airways (ANA) 787
Dreamliner, to go into passenger service later this year.
"ETOPs approval marks a major milestone for the Trent 1000
program, setting new industry standards," said Rolls-Royce, Trent
1000 Program Director Simon Carlisle. "We have produced the
quietest and lightest engine for the aircraft, with the lowest fuel
burn over the lifetime of an engine, contributing to the 787's
target of delivering 20 per cent less CO2 than previous generation
aircraft. We now look forward to supporting Boeing's own ETOPS
programme and to powering the 787 Dreamliner's entry into service
with All Nippon Airways."
The Trent 1000, which ran for the first time in 2006, was
granted FAA certification in August 2007, and has amassed more than
10,000 hours of ground and flight tests. The engine powered the 787
Dreamliner's first flight in December 2009 and has since powered 80
per cent of all test flights. The engine powers five out of the
seven aircraft in the 787 flight program. The Trent 1000 also
recently passed 2,800 hours of flight testing, accounting for the
majority of the 787 Dreamliner flight test program.
