New composite fuselages manufacturing processes

Abstract

The present document describes a new concept of composite fuselages manufacture, oriented towards the minimization of manufacturing costs through the generation of a monocoque fuselage structure, that allows to reduce the number of rivets and also the components joining operations, by means in addition of a process that avoids the use of molds, finally producing a lightweight and adaptable structure. The process in turn facilitates a high level of automation in the manufacture of composite fuselages and opens the door to a greater acceptance of this application in the aeronautical sector. The document outlines the design of the manufacturing process and the implementation of that particular production process for the manufacture of a real-scale concept demonstrator within the MTorres facilities, showing the reduction of the production cycle and the general manufacturing costs based on the simplification of the structural design and the integration of components into just one piece. Other additional variables that can benefit the reduction of costs and cycle times of the production process are also evaluated.
