  • Publication number: 20240109640
    Abstract: A thermal and acoustic insulation system for an aircraft, to be received between an inner surface of an aircraft primary structure, such as an aircraft fuselage structure, and a surface of a panel arrangement delimiting an aircraft cabin, the surface facing away from the aircraft cabin, comprises an insulation package and at least one sensor adapted to measure a level of humidity present in the insulation package. The insulation package comprises a core layer having a thermal and acoustic damping performance, and a packing layer enclosing the core layer. The packing layer is provided with a plurality of normally closed and selectively openable drainage openings which are actuatable to change between their normally closed state and an open state.

  • Publication number: 20240109642
    Abstract: A multifunctional thermal and acoustic insulation system having a multilayer structure and a plurality of functional components formed integrally and non-exchangeably with the multilayer structure. The multilayer structure has a thermal and acoustic damping performance and comprises, in a stacked arrangement, a continuous first outer layer, a core layer and a continuous second outer layer. The core layer is between the outer layers so that the outer layers cover the core layer at least on opposite sides thereof. Functions of the functional components are related to at least one of the thermal and the acoustic damping performance of the multilayer structure and the functional components are provided on a first outer layer side of the core layer and/or on a second outer layer side of the core layer.

  • Patent number: 10860298
    Abstract: A computer-implemented method for editing one or more properties of one or more model elements in a block diagram of a technical computing environment. The model elements include blocks and variables in blocks, wherein one or more properties are assigned to each model element. The technical computing environment has a model editor, a data definition tool and a code generator. A processor of a host computer opens a block diagram in the model editor, displays a list of model elements present in the block diagram, receives a selection of one or more model elements, highlights the selected model elements, receives an edit command to set a new value for a chosen property of the selected model elements, and sets the chosen property to the new value. A non-transitory computer readable medium and a computer system is also provided.

  • Patent number: 9023260
    Abstract: A molded part and a method for producing the molded part. The molded part is rotationally symmetrical or at least partially annular in cross section and formed by a plasticized polymeric mass containing fibers being injected through an injection opening into a cavity of a molding tool. Once the polymeric mass has solidified, the molded part is removed from the tool. Injection into the cavity takes place through at least two injection openings in such a way that the fibers are aligned predominantly in the main stress directions of axial tension and torsion in the molded part.
