Abstract
The invention concerns a blade having an axial length L, expressed in meters, equal by approximately 20%, to the value of L0 given by the following formula (I): L0=0.426262−5.14288.D+23.1798.D2−44.2505.D3+30.8841.D4, 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. The invention is useful for cooling a motor vehicle engine.
