Abstract
A rotating screen, for use with a centrifugal fan of an engine, includes a hub having a rotational axis and a plurality of blades extending radially outwardly from the hub. Each of the blades includes a root adjacent the hub, a tip, a leading edge extending between the root and the tip, and a trailing edge extending between the root and the tip. The blades also include an airfoil shape. The rotating screen also includes a band concentric with the hub and interconnecting the tips of the respective blades.
