Five stages of blisks optimize the weight of the BR725 high-pressure compressor, while 3D aero optimization and the introduction of elliptical leading edges lead to higher efficiency. The BR725 combustor is based on proven BR715 design, which is renowned for its low emissions and long life. The high-pressure turbine features two shrouded stages and profiled end walls. Via active tip clearance control cruise fuel burn can be improved.
