Engine Will Power The Gulfstream G650
Rolls-Royce has received type
certification for the new BR725 engine that will power the first
flight of the Gulfstream G650 business jet later in the year. Type
certification from the European Aviation Safety Agency (EASA) is
for thrust ratings of 16,100lbf (71.6 kN).
Since first engine run in April 2008, the BR725 has completed
all major development testing as well as accumulating almost 1,100
running hours and 3,500 engine cycles.
Dr Norbert Arndt, Director Engineering, Rolls-Royce Deutschland,
said: "The BR725 development program has progressed extremely
quickly and efficiently with a clear focus on technology and
delivering key milestones. Test results have been outstanding and
confirm all of our expectations. We are very proud to have achieved
this certification milestone on schedule. We are now looking
forward to first flight and the flight test program."
During development testing the engine demonstrated exceptional
performance operating at sea-level and altitude conditions. It also
proved its ability to cope with bird-strike, ice, hail and water
ingestion as well as passing the critical fan blade containment
test, during which a fan blade is deliberately released at maximum
speed. The fan blade containment test was performed in a new indoor
test bed at the company's Derby facilities.
Testing was undertaken at various Rolls-Royce locations in
Europe and the US, including Dahlewitz in Germany, Derby in the UK
and the Rolls-Royce outdoor jet engine testing facility, located at
NASA's John C Stennis Space Center, Mississippi, USA as well as the
altitude test bed at AEDC (Arnold Engineering Development Center)
in Tullahoma, Tennessee, USA.
The G650 program was launched in 2005 and Rolls-Royce was
selected to power this new business jet. Testing of first
development engines began in spring 2008. First flight test engines
were dispatched to Gulfstream from the Rolls-Royce Dahlewitz
facility earlier this year. First flight of the G650 is planned for
later this year, BR725 serial production is scheduled for 2010 and
the G650 is due to enter service in 2012.
Developed to rigorous standards, the BR725 has completed a
demanding development schedule hitting all milestones and
development gates as planned at the program outset. The BR725 is
the sixth new civil engine development program to come out of
Rolls-Royce on time and on budget in as many years.
