Abstract
A self retracting screen for turbomachinery comprised of a number of interlocking wires, the wire ends being pivotally attached to the periphery of the normal inlet of the turbomachinery. Preferably, the wires are elliptical, or streamlined, in cross-section such that the major diameters of the elliptical cross-section of the wires when the screen is closed are substantially parallel to the turbomachinery inlet stream.
