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.

A windage shield for use in a fluid flowpath within a gas turbine engine to reduce fluid turbulence in a region of a first and second member and a fastener, each member having a generally radially extending flange connected together by the fastener, wherein an end of the fastener protrudes axially beyond said first member in the upstream direction, said windage shield comprising: (a) a radially extending portion captured between the fastener and the first member; (b) a recessed region within said radially extending portion wherein the upstream protruding end of said fastener provides a generally flush interface between the protruding end of said fastener and surrounding surfaces adjacent said upstream end; and (c) a cylindrical section extending axially from said flange and extending downstream of said first and second members.
