Abstract

The invention concerns a blade having an axial length L, expressed in meters, equal by approximately 20%, to the value of L given by the following formula (I): L =0.426262−5.14288.D+23.1798.D −44.2505.D +30.8841.D , D being the blade diameter expressed in meters. The invention enables to substantially reduce the blade axial space requirement, for a given diameter and for obtaining the desired performance.
