Description
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.
