Abstract
Official abstract text for this publication.
The present invention relates to a fire resistant fan casing for a gas turbine engine. The casing has a projection such as a reinforcing rib or a mounting pad. The projection comprises at least one shell portion formed of a fiber/plastic composite material encasing a core of fire resistant material such as a metallic material or a ceramic matrix composite material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gas turbine casing comprising: a radially-outwardly-extending projection, wherein the radially-outwardly-extending projection comprises at least one shell portion formed of a fibre/plastic composite material encasing a core of fire resistant material so as to maintain structural strength of the projection while improving fire resistance of the gas turbine casing. 2. The gas turbine casing according to claim 1 wherein the casing is an annular casing with the projection at least partly circumscribing the annular casing. 3. The gas turbine casing according to claim 1 wherein the fire resistant core is a metallic, metallic matrix composite, ceramic or a ceramic matrix composite core. 4. The gas turbine casing according to claim 3 wherein the fire resistant core is a titanium core. 5. The gas turbine casing according to claim 1 wherein the fibre/plastic composite material comprises carbon, glass, aramid or boron fibres and a bismaleimide (8MI), polyimide or epoxy resin. 6. The gas turbine casing according to claim 1 wherein the projection comprises a spacer portion spacing the shell portion from the casing. 7. The gas turbine casing according to claim 1 wherein the projection is a reinforcing rib. 8. The gas turbine casing according to claim 1 wherein the projection is a mounting pad. 9. A gas turbine engine comprising the gas turbine casing according to claim 1 .
