Abstract

It is proposed to solve the problem of designing a fan rotor manufactured from a thin metal disc in such a way that it can be manufactured cost-effectively and at the same time produce a greater air output whilst causing less noise. This is achieved by a special shape of the fan blades. <IMAGE>
