Abstract (en)
A variable-geometry fan, in particular for cooling the lubricant of an internal-combustion engine, comprising a hub (1) bearing a ring of blades (2) having an elastically deformable structure and incorporating laminas (11) made of a shape-memory alloy. The application of thermal energy to the laminas (11), so as to vary the geometry of the blades (2), envisages circulation of a hot fluid and of a cold fluid through internal ducts (9) of the blades (2).
