Summary:A fastener shield (100) for use in a fluid flow path within a gas turbine engine for reducing fluid drag and heating generated by fluid flow over a plurality of circumferentially spaced fasteners. The fastener shield (100) has a radially-extending, downstream-facing mounting flange (104) with a plurality of circumferentially spaced bolt holes (106) positioned to receive respective engine mounting bolts (160) therethrough and to attach the mounting flange (104) to elements of the turbine engine. A curved, upstream-facing fastener shield cover (108) is positioned in spaced-apart relation to the mounting flange (104) for at least partially covering and separating an exposed, upstream-facing portion of the bolts from the fluid flow to thereby reduce drag and consequent heating of the bolts (160).
