摘要： A floor system for a cabin of a vehicle is proposed, the floor system including a floor panel having a bottom layer, a top layer and a continuous stiffening structure having an alternating arrangement of elongated first depressions and elongated protrusions arranged between the bottom layer and the top layer, an elongated cover component, and at least one seat rail component. The cover component has an upper surface, a lower surface, and an elongated second depression reaching from the upper surface to the lower surface and having a shape that corresponds to the shape of the first depressions. The cover component is configured to be mounted inside a first depression that is accessible through an elongated cutout extending along a depression of the stiffening structure. The at least one seat rail component is attachable to the cover component to provide a seat rail along the floor panel.

摘要： A method of forming a dry floor assembly includes cleaning an upper layer with methyl ethyl ketone (MEK) prior to bonding the upper layer to a carbon wicking layer. Said cleaning removes release agent from the upper layer. The method also includes bonding the upper layer to the carbon wicking layer after said cleaning.

摘要： An aircraft cabin floor arrangement includes two floor support part-structures, each having vertical support members, a beam member, cantilevering members and a seat rail. The beam member and the seat rail extend in a first direction with the seat rail being carried by the beam member. The cantilevering members cantilever in a second direction transverse to the first direction. The vertical support members extend in a third direction transverse to the first and second directions. The two floor support part-structures are each configured to be arranged along opposing side portions within an aircraft fuselage structure and are configured to transfer load from the cantilevering members and the beam member to the fuselage structure. The cantilevering members and the beam member are configured to carry a cabin floor configured to provide a load transfer in a plane direction of the floor and to contribute to a stiffening of the fuselage structure.

摘要： An aircraft-floor element comprising a first cladding element configure to be swung from a first position to a second position. In the first position, the first cladding element is arranged parallel to a main plane of the aircraft-floor element and on a side of the aircraft-floor element which is directed towards a passenger cabin. In the second position, the first cladding is arranged at an angle to the main plane of the aircraft-floor element, wherein it forms a cladding for a cargo space. An aircraft zone having an aircraft-floor element and an aircraft having such an aircraft zone are also disclosed.

摘要： A heatable floor panel for an aircraft, with a supporting level, a heat-generating level and a heat-conducting level. The heat-generating level comprises a fiber composite layer with fibers and with a matrix surrounding the fibers. The fibers are at least partially formed as conducting fiber, and the conducting fibers are formed as carbon fibers with an electrically insulating coating. The conducting fibers integrated in the floor panel in order to conduct a heating current through them. Due to the electrically insulating coating of the conducting fibers, leakage currents are avoided. The carbon fibers serve not only as heating elements, but, at the same time, also as reinforcing fibers of the fiber composite layer or of the floor panel.

摘要： An assembly method includes a succession of assembly steps of assembling fuselage components of the fuselage portion of the aircraft, for example the nose of the aircraft, to form a fuselage body, a mounting step of introducing, into the fuselage body thus formed, a floor module having at least a predetermined width, and which can be provided with items of equipment, and a fastening step of fastening the fuselage body to the floor module such that the floor module shapes the final shape of the fuselage body and the assembled fuselage portion is obtained, the floor module, which has at least a suitable predetermined width, making it possible, when it is incorporated into the fuselage body, to provide the fuselage body, which is slightly flexible, with its desired and definitive shape corresponding to the desired and definitive shape of the assembled fuselage portion.

摘要： A floor structure for an aircraft includes a rail that defines a recess having an opening and a bottom and designed to receive one or more attachment elements, a covering element arranged above a segment of the recess so as to provide a complementary bearing surface above the opening, and a cellular supporting structure having a first end that rests on the bottom of the recess, and a second end supporting the covering element. Thus, the covering element can be sufficiently thin to avoid or limit the formation of steps at the surface of the floor structure.

摘要： A fuselage for an aircraft includes a pressure deck assembly extending along a roll axis of the fuselage. The pressure deck assembly includes longitudinal beams and a pressure deck. The longitudinal beams extend lengths along the roll axis of the fuselage. The pressure deck extends between the longitudinal beams along the lengths of the longitudinal beams. The pressure deck is compliant along a pitch axis of the fuselage. The fuselage includes a bulkhead extending along a yaw axis of the fuselage. The bulkhead is joined to the pressure deck assembly at a corner joint. The fuselage includes a compression chord extending a length along the pitch axis of the fuselage. The compression chord is joined between the pressure deck assembly and the bulkhead at the corner joint such that the compression chord extends on an outside of the corner joint.

摘要： A method for producing a crossmember for a vehicle prepares a workpiece having different thicknesses and a preliminary contour from a metal sheet of uniform thickness by flat roll forming to achieve different local thicknesses. The method cuts out the workpiece, and bending roll forms the workpiece to form a crossmember with a cross section having at least two flanges opposite one another, and a web situated between said flanges. The distance between the flanges is not constant along a longitudinal extent of the crossmember, and a thickness profile at least of the web is determined by the flat roll forming. The local thicknesses and the preliminary contour are such that a geometrical shape of the crossmember corresponds to a predetermined geometrical shape with different thicknesses and heights of the web and differently shaped regions of the flanges along the longitudinal extent of the crossmember.

摘要： An aircraft flooring system is provided, made up of a low-weight carpet tile which functions both as a moisture barrier and as the loop part of a hook-and-loop system, for coupling to a hook part of a hook-and-loop system, which is bound to an aircraft floor. Specifically, a barrier backing within the carpet tile, comprising a nonwoven fabric portion, is able to act as the moisture barrier and the loop part, which allows for coupling of the carpet tile with the floor, without the need to add additional loops to the carpet tile, thereby realizing savings in material cost and weight.
