Abstract:

A windage shield for use with a pair of annular members oriented in an abutting end-to-end arrangement to define one boundary of a fluid flow path, each of the members having a radially extending flange at their respecting abutting ends for coupling the members to each other. The flanges are coupled by a plurality of circumferentially spaced bolts having a head and a nut which protrude into the fluid flow path. The windage shield comprises an annular ring having a first surface with a plurality of circumferentially spaced arcuate grooves formed therein. Each of the grooves is shaped to receive a preselected number of the bolt heads when the ring is positioned against a corresponding flange. A second surface of the ring opposite the first surface includes a plurality of apertures extending through the ring to the first surface with each of the apertures being located between a respective adjacent pair of the arcuate grooves. Each aperture has a countersunk portion on the second surface.
