  • Casing assembly
    Patent number: 12292002
    Abstract: There is provided a casing assembly for a gas turbine engine comprising: a casing and electrically conductive intumescent material extending around the casing. The intumescent material is being activatable in response to electrical current to expand. The casing assembly comprises an electrical activation line extending around the casing to activate the intumescent material. The activation line extends in a pattern such that an activation area which circumscribes the activation line has an axial extent of at least 50% of the casing and a circumferential extent of at least 50%, to thereby activate the intumescent material at multiple locations over a corresponding area of the casing.
