  • Gas turbine engine blade containment arrangement
    Patent number: 9169045
    Abstract: A gas turbine engine blade containment arrangement comprises a casing, a first layer of cellular material arranged within the casing, a septum layer within the first layer of cellular material, a second layer of cellular material within the septum layer, a strong and ductile layer within the second layer of cellular material and a layer of abradable material within the strong and ductile layer.
    Type: Grant

    Date of Patent: October 27, 2015
    Assignee: ROLLS-ROYCE plc
    Inventor: Daniel N. S. Clark
  • Characterisation of soft body impacts
    Patent number: 8280704
    Abstract: The fragmentation of a bird or similar soft body, following its impact on an angled target plate, is modeled by representing the body as a combination of fragments and slurry, their relative proportions depending on the severity and angle of impact. The method is particularly suitable for modeling the behavior of a bird striking an obscuring intake of a gas turbine engine.

  • Characterisation of soft body impacts
    Patent number: 8220309
    Abstract: An apparatus for characterizing the fragmentation of a body following impact with a surface, particularly the fragmentation of a bird following impact with part of an intake of a gas turbine engine, comprises a gun, a target plate, a soft recovery plate across which the body's trajectory can be tracked, and a soft recovery system, characterized in that damage to the body is caused substantially only by the impact on the target plate.

  • COATING OF METALLIC ARTICLES TO RESTRICT ICE ACCUMULATION
    Publication number: 20110070093
    Abstract: An anti-icing coated metallic substrate includes molecules of an anti-icing material chemically bonded to the metallic substrate. The substrate is suitably a metallic article, particularly a high-performance weight-critical rotor component such as an aircraft propeller blade or an air intake fan blade of a gas turbine engine.
