Abstract:
The invention relates to a fan, in particular for an aircraft cooling unit, comprising a wheel ( 128 ) and a shaft line ( 136 ) for driving the wheel about an axis (A), said wheel including a hub ( 138 ) supporting an annular row of blades ( 140 ), and means ( 142 ) for connection to said shaft line that are housed inside said hub. The fan is characterized in that the connection means include at least one meltable safety element ( 158 ) designed to be broken and to rotationally disengage at least a portion of the connection means from the shaft line when a torque for driving the wheel that is transmitted by the shaft line exceeds a specific threshold.

Claim (Index 1):
A fan, in particular for an aircraft cooling unit, comprising a wheel and a shaft line that drives the wheel about an axis (A), said wheel comprising:\n a hub carrying an annular row of blades, and means for connection to said shaft line, which are housed inside said hub, said connection means comprising a bush comprising an internal bore configured for receiving said shaft, said bush being located approximately in a plane (P, P\u2032) transverse to said axis or is traversed by said plane, which passes approximately through said blades, wherein said connection means comprise at least one fusible safety element which extends or is arranged around said axis (A) and which is configured to break and rotationally disengage at least one part of said means of said shaft line when a drive torque of the wheel transmitted by said shaft line exceeds a certain threshold, said at least one fusible element having an elongated shape, its extension axis being parallel to said axis (A).
