BR710

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.
