Structural cover for gas turbine engine bolted flanges

摘要

A method enables a structural cover for a gas turbine engine (10) to be manufactured. The method includes forming a torroidial body (52) including an integrally-formed windage cover portion (70) and a seal flange portion (72), and forming a plurality of fastener openings (92) extending from a forward side (58) of the torroidial body to an aft side of the torroidial body (60), such that when installed in the gas turbine engine, the windage cover portion facilitates shielding the fastener openings from a gas flow path. <IMAGE>
