Abstract

1369229 Gas turbine engine casings; compressor casings ROLLS-ROYCE (1971) Ltd 29 Sept 1972 [12 Oct 1971] 47345/71 Headings F1C F1J and F1T The invention relates to a means for reducing the damage which would result from the breaking- off of part of the rotor system of a rotary machine, the invention being described with reference to the fan assembly of a gas turbine ducted fan engine. The fan assembly comprises a rotor (20) having fan blades 24 which rotates within a fan casing 22. An annular recess 26 is formed in the inner wall of the fan casing around the fan blades and an annular axially-extending annular projection 28 is formed at the forward end of the annular recess to form a hook-shaped member with which a broken-off part of the rotor will engage.
