ABSTRACT:
An improved windage shield is provided for use with turbomachinery members partially defining an internal flow path wherein the members are connected by a fastener which protrudes beyond one of the members. The windage shield comprises a portion which is captured between the fastener and one of the members and a cylindrical section which extends downstream of the members to form a smooth cover for isolating the members from the internal fluid flow. The protruding fastener end is recessed into, and generally flush with, the captured portion of the windage shield.
