Abstract (en)

[origin: FR2781843A1] The invention concerns a blade having an axial length L, expressed in metre, equal, by approximately 20 %, to the value of L0 given by the following formula (I): L0 = 0.426262 - 5.14288.D + 23.1798.D<2> - 44.2505.D<3> + 30.8841.D<4>, D being the blade diameter expressed in metre. 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.
