Abstract: A method of using solid profile rods instead of the usual filament coils for additive manufacturing methods such as 3D printing for industrial applications such as aircraft manufacturing, and to enable a more rapid production of fiber-composite components. The additive manufacturing device, or the 3D printer which generates the component layer by layer, respectively, comprises a material magazine in which a plurality of profile rods are stored. The profile rods are pre-tailored and are adapted to the component layer by layer. The profile rods, when printing, are successively retrieved from the material magazine and, by way of an infeed installation, guided to the nozzle of the additive manufacturing installation and subsequently applied to the printing bed so as to form the component layer by layer.

Abstract: A component made of a fiber-reinforced plastic, having a first surface portion, a second surface portion and a transition portion, which is enclosed by the first surface portion and the second surface portion, wherein surface tangents to the first surface portion and the second surface portion are not parallel, at least in regions adjacent to the transition portion. The transition portion has a curvature adjoining the adjacent surface portions in a tangentially constant manner, wherein an arrangement of at least two layers made of a fiber-reinforced plastic extends from the first surface portion, over the transition portion, onto the second surface portion, and fibers at least of one of the layers run with an unchanging orientation on the first surface portion and the second surface portion and, on the transition portion, run in a laterally offset, inflected or curved manner along the running direction.

Abstract: An aircraft airflow modification device, comprising: at least one resiliently deformable base member; and at least one resiliently deformable flap member that extends from the resiliently deformable base member. Deformation of the resiliently deformable base member from a first state to a second state results in corresponding deformation of the resiliently deformable flap member from a first state to a second state.
