  • Gas turbine engine casing
    Patent number: 5273393
    Abstract: A gas turbine engine is mounted from a pylon. The gas turbine engine has an annular fan casing which is provided with a composite containment ring. A plate is attached to the underside of the pylon, the ends of which extend radially inwards towards the fan casing. The plate acts to direct the containment ring, as it distorts under the impact of a blade, away from the pylon. The plate reduces the amount of interaction between the containment ring and the pylon so minimising any damage to the pylon and the associated aircraft structure.
