Disclosed is a process for producing a substantially shell-shaped component, from substantially carbon-fiber-reinforced synthetic material having at least one local reinforcing zone and at least one stiffening element, in particular a fuselage shell, a wing shell, a vertical stabilizer shell or horizontal stabilizer shell of an aircraft or the like. The process according to the invention comprises the following steps:

Process for producing a substantially shell-shaped component

A service apparatus for a transportation means comprises a first component in the form of an air shower with an air inlet and at least one air outlet, and a second component in the form of an illumination device. The first component and the second component are arranged essentially centrically in relation to each other, wherein one of the two components encloses the other component essentially in a ring-shaped manner. In this way an integral reading light with a forced-air nozzle, or an integral forced-air nozzle with a reading light, is implemented that uses little design space.

A method for fabricating a stringer-stiffened shell structure using fiber composite materials involves the following steps. A fiber reinforced skin member having a specified surface curvature is laid onto a correspondingly curved mold surface of a shell mold. Stringer core blanks are cut from a cured plate of fiber composite material, whereby each blank has a narrow edge with a curvature matching the curvature of the skin member. These stiff pre-cut blanks are arranged extending along and vertically protruding from the skin member, with the narrow edges of the blanks lying in contact along the skin surface. An auxiliary frame is placed around the perimeter of the shell mold, and the ends of the stringer core blanks are received in slots in the frame to hold the blanks in proper positions. Then, stiffening profile members are laid lengthwise along and against the stringer core blanks and the adjoining areas of the skin member, whereby these profile members are made of uncured fiber composite material so that they are easily deformable along the skin member and the stringer core blanks. The assembled structure is pressurized and cured so as to integrally bond the components to each other and fully cure and harden all of the components. A stiffening stringer of the finished structure is formed by a respective stringer core blank sandwiched between two adjoining stiffening profile members.
