  • Publication number: 20130098491
    Abstract: Pressure compensation device (100) deployed in an element that contains a flammable substance that compensates pressures between interior (101) of the element and exterior atmosphere (102) in which said element is deployed, by means of a continuous primary circulation (300) of air through primary channel (103) in said device (110) that communicates interior (100) and exterior (102) of the element, further comprising a secondary channel (104) integrated in the device (100) itself, communicating interior (102) and exterior (102) of the element, comprising said secondary channel (104) in the interior zone of the element a sheet (105) such that, in the event primary continuous circulation (300) of air through primary channel (103) is interrupted, said continuous circulation continues through secondary circulation (400) of air to interior (101) of the element, this secondary circulation (400) of air being capable of breaking sheet (105) of secondary channel (104).

  • Patent number: 8424806
    Abstract: Aircraft component with panels (11) stiffened with stringers (15) configured with a central section (17) and some feet (19) in which there are zones of potential intersections or interferences of said stringers (15) with spars (25) and ribs (27), in which the configuration of the ends of the stringers (15) affected by said intersections or interferences includes a first section (41) in which the height of the central section (17) of the stringer (15) is reduced until it disappears and the width of the feet (19) is increased until it reaches a predetermined width A and a second section (43) with some extended feet (23) of said predetermined width A and no central section (17), including in said first section (41) the mechanical means (31) for binding the end of the stringer (15) to the skin (13). The invention also relates to a method for manufacturing said panels (11).

  • Patent number: 8276848
    Abstract: Rib structure for a torsion box of an aircraft wing or a horizontal stabilizer. The structure comprises a center element which extends between the front spar and the rear spar of the torsion box, a series of vertical stiffening elements arranged between an upper skin and a lower skin of the torsion box. The vertical stiffening element consists of a first lateral wing which extends in the direction of said front spar and a second lateral wing which extends in the direction of said rear spar. These lateral extensions emerge from respective opposite sides of the vertical body and are attached side to side to the center element of the rib.

  • Patent number: 8141820
    Abstract: An aircraft manhole including a skin panel of an aircraft structure, wherein an outer door and an inner door of the aircraft manhole are positioned on the skin panel. The aircraft manhole further includes stringers installed on the skin panel positioned on and attached to the skin, and fixing edges partially projecting through the manhole on the side for positioning the outer door and the inner door. The aircraft manhole also includes reinforcements arranged between the outer door and the inner door of the manhole that are attached to the skin, the reinforcements forming the fixing edges on one of its sides, and a cavity arranged in the skin to allow installing the outer door, thus maintaining the aerodynamic surface of the assembly as well as its tightness.
