Current revision
The BR700 family of engines was developed by BMW and Rolls-Royce plc through the joint venture company BMW Rolls-Royce to power regional and corporate jets. Rolls-Royce took full control of the company in 2000 and is now known as Rolls-Royce Deutschland.
The company was established in 1990 and the first engine run (BR710) took place in September 1994.
BR710-48
The BR710, a twin shaft turbofan, entered service on the Gulfstream V in 1997 and the Bombardier Global Express in 1998. This version has also been selected to power the Gulfstream G550.
Another rerated version, with a revised exhaust system, will shortly enter service in the RAF Nimrod MRA4s.
Comprises a 48in diameter single stage fan, driven by a 2 stage LP turbine, supercharging a 10 stage HP compressor (scaled from the V2500 unit) and driven by a 2 stage, air-cooled, HP turbine.
BR715-58
Another twin shaft turbofan, this engine was first run in April 1997 and entered service in mid-1999. This version powers the Boeing 717.
A new spool, comprising a 58in diameter single stage fan, with 2 stage IP compressor driven by a 3 stage LP turbine, is incorporated into the BR715. The HP spool is similar to that of the BR710.
