The Rolls-Royce BR700 family of turbofan engines powers regional jets and corporate jets. The BR710 is a twin shaft turbofan, and entered service on the Gulfstream V in 1997 and the Bombardier Global Express in 1998.
The BR710 is typical of this configuration.

Bombardier Global Express

Bombardier Global 5000Bombardier Global 6000Global Express
The BR710 is a twin shaft turbofan, and entered service on the Gulfstream V in 1997 and the Bombardier Global Express in 1998.
Initially powered by two BMW-Rolls-Royce BR710s, it shares its fuselage cross section with the Canadair Regional Jet and Challenger 600 with a new wing and tail.

Gulfstream V

C-37AC-37C-37 Gulfstream V
The BR710 is a twin shaft turbofan, and entered service on the Gulfstream V in 1997 and the Bombardier Global Express in 1998.
Compared to the Gulfstream IV, the engines are changed from Rolls-Royce Tay to Rolls-Royce BR700-710A1-10 with increased thrust, higher bypass ratio, and Full Authority Digital Engine Controls (FADEC).

Another rerated version, with a revised exhaust system, was selected for the now cancelled Royal Air Force Nimrod MRA4s.
The rebuilt aircraft would have extended the operating life of the Nimrod fleet by several decades and significantly improved the aircraft by installing more efficient Rolls-Royce BR700 turbofan jet engines to almost double the flight range.

It was developed by BMW and Rolls-Royce plc through the joint venture BMW Rolls-Royce AeroEngines GmbH, established in 1990.
In 1990, BMW and Rolls-Royce established the BMW Rolls-Royce joint venture to produce the BR700 range of engines for regional and corporate jets, including the BR725 powering the Gulfstream G650, which received EASA Type Certification in June 2009.

The Rolls-Royce BR700 family of turbofan engines powers regional jets and corporate jets.
Rolls-Royce plc was revealed as the engine supplier for the Global 5500/6500 with the Rolls-Royce Pearl 15, an improved BR710 resembling the Gulfstream G650's BR725.

Gulfstream G650

G650Gulfstream 650650
The BR725 is a variant of the BR710 with a three-stage-axial flow low pressure turbine to power the Gulfstream G650.
It will have a MTOW of 107,600 lb (48,800 kg) and the 18,250 lbf (81.2 kN) turbofans should burn 2-3% less fuel than the G650's R-R BR725s.

Rolls-Royce has announced that it intends to offer the BR725 for the United States Air Force’s (USAF) B-52 Stratofortress re-engining, although a request for proposals has yet to be issued by the USAF.
Possible contender engines to replace the TF-33 including the General Electric TF34, the General Electric Passport, the Pratt & Whitney PW815 and the Rolls-Royce BR725.

The IP compressor booster stages supercharge the core, increasing core power and thereby net thrust.

Specific thrust

However, a larger fan is required, to keep the specific thrust low enough to satisfy jet noise considerations.

Axial compressor
