The 100-seat Boeing 717-200 is powered by two Rolls-Royce BR715 turbofans.
The BR715 uses the same highly efficient BR700 engine core as the BR710, 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 100-seat Boeing 717-200 is powered by two Rolls-Royce BR715 turbofans
- BR715 emissions and noise levels are far below current regulations
- BR715 first run in April 1997, engine certificated August 1998, entry into service in mid-1999
- More than 300 BR715 engines delivered to customers worldwide
Selection of the BR715 engine 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 engine
- Both BR700 engine family members, the BR710 and the BR715, 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
- The BR715 features a 58 inch diameter fan and a two-stage booster driven by a three-stage LP turbine.
