The invention provides an improved method (100) for manufacturing a stiffener structure for an aerospace structural component (19) and an improved stiffener structure (10).
Abstract:
A panel for a surface covering system of a plurality of like panels, the panel comprising: a base layer; a first joint extrusion attached along a first edge of the base layer; a second joint extrusion attached along a second edge of the base layer, opposite the first edge; a covering layer covering at least part of the first joint extrusion and at least part of the second joint extrusion; wherein the first extrusion is configured to join to a second extrusion of an adjacent like panel, and the covering layer substantially conceals the first extrusion and the second extrusion when installed.
Abstract:
A corrugated metal plate comprises a plate configured to define a series of crests and troughs, where the plate has longitudinal edges extending parallel to longitudinal axes of the crests and the troughs and transverse edges extending orthogonally to the longitudinal axes of the crests and the troughs. The corrugated metal plate further comprises at least one of: at least one longitudinal flange extending from each longitudinal edge, and at least one transverse flange extending from each transverse edge.
Abstract:
The present invention relates to an improved composite panel which may be used to form an item such as a door (10). The composite panel includes at least one corrugated panel (12) located within a space defined by a second member (16). The second member (16) includes a back panel (16A), a peripheral edge(16B) and a front edge (16C). The space is bounded, at least in part, by the back panel (16A), the peripheral edge (16B), and the front edge (16C). The composite panel has particular, but not exclusive, application in the building and construction industry.
Abstract:
A building component (10) has first and second parallel and spaced apart edges (12) and (4,) a first panel portion (16) and first and second members (18) and (20). The first and second members (18) and (20) are located on the same side of the first panel portion (16). The members (18) and (20) extend along the first and second edges (12) and (14). A second panel portion (42) is demountably connected to the first panel portion (16) in a face to face relationship. This creates a plurality of cavities (44) within the building component (10). A plurality of holes (26) is formed in the component (10) to enable passage of services such as electricity, gas and water through the component (10).
Abstract:
A composite panel system comprises a floor, a wall panel and a roof panel which are fabricated with a structural frame; a mesh for bracing the structural frame; and a foam for bonding a cladding material to the mesh and frame to create a strong lightweight panel.
Abstract:
Systems, methods and devices for use with unmanned aerial vehicles (UAV). A central controller is coupled to the autopilot system for a UAV. Navigation is implemented by using two GPS antennas and obtaining a difference between the locations from these two antenna to arrive at a high precision bearing or direction of travel. This single GPS derived bearing is used to trigger all the various subsystems on the UAV for imaging or mapping. Areas and locations to be mapped and imaged are determined by geolocation and mapping and imaging equipment are triggered based on the single GPS signal derived from the two GPS antennas. To reduce vibration effects on navigational and imaging or mapping equipment, these are positioned as close as possible to the vehicle's center of gravity and are deployed in a shielded box on vibration isolation mounts.
