  • Patent number: 10835977
    Abstract: A metallic structure defines ribs and a skin supported by the ribs. The ribs may be defined by metal strips and the skin may be attached to the ribs. Alternatively, the skin may be defined by a plurality of tiles and the ribs may be defined by flanges of each of the plurality of tiles that cooperate to define the ribs. Tiles may be attached to separate rib lattice. Structurally weak locations at nodes where ribs intersect may be reinforced. The components may be brazed together and the stiffness of adjacent locations in the structure adjusted in the brazing operation to reduce the difference in stiffness and to reduce resulting stress risers. The metallic structure may be armored using metal foam to absorb the energy of a projectile.

  • Patent number: 10836133
    Abstract: A honeycomb core for dimensionally stable components (e.g., a reflector) in sandwich construction with a plurality of cells with a triangular cell cross section made from carbon fiber reinforced plastic. The honeycomb core is assembled from flat laminate strips by plugging, wherein the laminate strips have slots running transversely to the extension direction respectively on their longitudinal side. The laminate strips are connected to one another in such a way that the slots of three laminate strips engage in a positive-locking manner in one another at a respective intersection point to form the corners of the cells of the honeycomb core.

  • Patent number: 10823413
    Abstract: A combustion chamber assembly comprises a combustion chamber and a plurality of nozzle guide vanes. Each nozzle guide vane comprises an inner platform, an outer platform and an aerofoil. The combustion chamber comprises an annular wall which includes at least one box like structure. An outer wall of each box has a plurality of apertures for the supply of coolant into the box and the interior of the box is divided into at least two regions. The upstream end of each box has apertures to supply coolant from a first region of its interior onto an inner surface of the inner wall to form a film of coolant. The downstream end of each box has apertures to supply coolant from a second region of its interior onto a surface of the inner or outer platform of the nozzle guide vanes to form a film of coolant.

  • Patent number: 10767363
    Abstract: An affordable Zero-Energy prefabricated modular building such as for housing, in which a Layered disposition of Envelope elements—including Structural Insulated Panels—in the wall, floor and roof sections of the building's thermal Envelope, provide a highly energy-efficient Building Envelope, which together with a modular building Support Structure including Aeriated Frames, and an adequately sized renewable energy power generator system, inexpensively achieves the energetic independence of the building. A method is disclosed for the adaptation of the building's design and construction to the bio-climatic conditions of its projected location, in which different possible configurations of the relevant elements of the Building Envelope, the building structure and the renewable power generator system are evaluated, discarding those configurations which don't meet the defined acceptable criteria for energy-efficiency, thermal isolation and water condensation risks.
