Abstract
Fan section comprising: a ratio of the product of the average axial chord of the blade by the axial chord at the blade root to the product of the square of the blade height (47) by the axial chord at the blade tip (21), is greater than or equal to the difference between the product of the maximum speed and the value 2.501 x 10⁻³ s/rad and the value 1.7148 x 10⁻¹, and a ratio of the axial chord at the blade root to the product of the square of the average axial chord by the blade height and by the axial chord at the blade tip, is greater than or equal to the difference between the product of the maximum speed and the value 0.2515 s/rad and the value 52.701.
