It then delivers this compressed air to the combustion system. The compressor comprises the fan and alternating stages of rotating blades and static vanes. Advanced aerodynamics Rotors and stators embody an aerodynamic design to maximise the efficiency of the compression process. The evolvement of aerodynamic design has been made possible by the continued development of computational fluid dynamics allowing accurate modelling of the airflow. Ice protection The Trent 1000 anti-icing function is designed to prevent ice formation due to water freezing as it hits cold metal. The core engine section stators (ESS) warm-air, anti-icing bleed (delivered from the Intermediate Pressure compressor) is switched on automatically only when needed, such as during descent – controlled by rating, altitude, ambient temperature, and forward speed – and on the ground during taxi in cold conditions such as freezing fog. The heated ESS removes the requirement for most fan anti-icing procedures.
