Description
The BR710 is a two-shaft, high-bypass-ratio engine
with a one-stage low pressure (LP) compressor and ten-stage
high pressure (HP) compressor, driven by a two-stage
HP turbine and two-stage LP turbine respectively. The
engine features a single low emissions annular combustor
with 20 burners.
The BR710 is part of the BR700 family which the BR715
also belongs. Both engine family members use the highly
efficient BR700 engine core, suitable for high cyclic
operation for thrusts between 14,000lbf and 23,000lbf.
All stages are optimised to keep noise to a minimum.
The BR710 is well suited to a range of operating environments
from hot and high airport operations to maritime patrol,
and has proven excellent performance characteristics
accross the board.
One of the military applications for the BR710 is the
BAE SYSTEMS Nimrod MRA4 which builds upon the trusted
partnership of the Rolls-Royce Spey engine in the Nimrod
MR2. Due to the harsh operating conditions this engine
will face in-service, the BR710 has been fully marinised
to prevent wear and corosion.
In addition to the Nimrod MRA4, the BR710 also powers
the Gulfstream C-37 (military version of G550), operating
in a military role.
The BR710 engine made its first run in 1994, right
on schedule. Its first flight – powering the new
Gulfstream V (G550) – was in November 1995. Certification
was in August 1996, again right on schedule. The first
flight of the Bombardier Global Express took place in
October 1996 followed by BR710 engine certification
in January 1997.
Due to their outstanding performance, BR710 powered
aircraft have established many world records in the
field of speed altitude. Long life on wing, low fuel
burn and excellent environmental performance lead to
low operating costs with maximum reliability.
