  • Casing made of organic matrix composite material that facilitates the discharge of smoke
    Patent number: 9920769
    Abstract: A gas turbine casing made of organic matrix composite material includes reinforcement densified by an organic matrix defines an inside volume. On its inside face the casing has a structural part with a first face facing the inside face of the casing, and an opposite second face defining a flow passage portion. Recesses opening out into the inside volume of the casing are present between the inside face of the casing and the first face of the structural part facing the inside face of the casing. In the event of a fire, the recesses allow gas coming from degradation of the resin of the casing to be discharged into the flow passage.

  • Method for mounting an acoustic panel in a housing of a turbomachine and turbomachine comprising an acoustic panel
    Patent number: 9657644
    Abstract: A method for mounting an acoustic panel on the inner surface of an annular housing of an axial turbomachine, the cylindrical acoustic panel comprising at least one longitudinal slot so as to define two opposing ends, the method comprising: bringing the two opposing ends closer together so as to reduce the cylinder radius of the acoustic panel; inserting the acoustic panel into the fan casing when the opposing ends are close together; deploying the opposing ends so as to increase the cylinder radius of the acoustic panel; and securing the acoustic panel to the housing by gluing.
