Rolls-Royce BR725 receives EASA cerfication
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 programme 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 programme."
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 Centre, Mississippi, USA as well as the altitude test bed at AEDC (Arnold Engineering Development Center) in Tullahoma, Tennessee, USA.
The G650 programme 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.
