摘要

The forward block of a vehicle consists of a heat exchanger and a fan, which is driven in rotation around a longitudinal axis (A). The fan blades (111) extend radially from the fan hub, towards the exterior. At least one part (119) of at least one blade is mobile relative to the hub and can move between a primary position, where the full transverse surface is reduced and a second position, where the full transverse surface is larger.
