Device and method for manufacturing a fiber-reinforced composite fuselage shell for an aircraft

摘要

A device and a method for manufacturing a fiber-reinforced fuselage shell for an aircraft, which fuselage shell for the purpose of reinforcement comprises several stringers that are spaced apart from each other, wherein the device includes a base frame comprising several supporting walls of different lengths for forming a curved mounting surface for the fuselage shell to be manufactured, wherein several actuators that extend radially outwards and that are longitudinally adjustable are affixed to the mounting surface, at the distal ends of which actuators in each case mold channels for receiving the stringers are attached, which mold channels are interconnected by means of flexible intermediate elements and/or further mold channels for forming a vacuum-tight closed mold surface.

1. A device for manufacturing a fiber-reinforced fuselage shell for an aircraft, wherein the fuselage shell comprises a plurality of stringers spaced apart from each other, the device comprising:
a base frame for forming a load-bearing, rigid, substructure with an outwardly-curved mounting surface for the positive-rigging of a fiber-reinforced fuselage shell to be manufactured; a plurality of actuators affixed to and extending radially outwards from the outwardly-curved mounting surface and being longitudinally adjustable; a plurality of mold channels attached at the distal ends of the plurality of actuators and configured for receiving the plurality of stringers; wherein the plurality of mold channels are interconnected by at least one of a plurality of elastic belts and additional mold channels for forming a vacuum-tight closed mold surface, wherein the plurality of elastic belts are arranged along longitudinal edges of the mold channels; and wherein the plurality of actuators are hingeably mounted, by associated joints, on the outwardly-curved mounting surface.
