<p>A swept blade design for the low pressure compressor rotor or fan of a ducted fan gas turbine engine has a leading edge which is inclined relative to an axial direction of airflow through the rotor stage. The sweep angle varying with blade, span height from the rotor axis has a negative or forward sweep near the rotor hub, changing to a positive or rearward sweep as span height increases, changing again near the tip to negative or forward sweep. <IMAGE></p> |
