The BR700 family meets the power requirements of regional aircraft with between 80 and 130 seats and those of ultra long-range business jets.

Both engine family members use the highly efficient BR700 engine core, suitable for high cyclic operation for thrusts between 14,000lb and 23,000lb. This core incorporates a ten-stage HP compressor, a low-emission annular combustor with 20 fuel burners and a two-stage shrouded high-pressure turbine. All stages are optimised to keep noise to a minimum.

The BR710’s low-pressure system features a 48-inch diameter fan driven by a two-stage low-pressure turbine and the BR700 core. The engine made its first run in 1994, right on schedule. Its first flight – powering the Gulfstream V – was in November 1995. Certification was in August 1996, again right on schedule. The BR710 also powers the Gulfstream G500 and G550. The first flight of the Bombardier Global Express took place in October 1996 followed by BR710 engine certification in January 1997.

The BR715 features a 58-inch fan and a two-stage booster driven by a three-stage low-pressure turbine. Its selection to power the Boeing 717 is due to its combination of high performance, environmental friendliness, low cost of ownership and low risk derivative technology approach.

Two-shaft, high-bypass-ratio engines
Both BR700 engine family members incorporate the BR700 core engine, with a ten-stage HP compressor, a single low emissions annular combustor with 20 burners and a two-stage shrouded HP turbine
Different thrust levels of the two engines are realised by adapting the LP systems
In the case of the BR710 the 48-inch diameter fan is driven by a two-stage LP turbine
The BR715 features a 58-inch diameter fan and a two-stage booster driven by a three-stage LP turbine
