WASIS

The aim of this project is the development of a composite fuselage structure based on the lattice stiffening concept and optimizing geometrical and mass properties of transition zones of fuselage structural joints. The material to be utilised in order to develop an all composite fuselage structure is carbon fibre impregnated with an epoxy resin.

Objectives:
To make the step towards “Vision for 2020”, the WASIS project consortium is going to achieve several ambitious goals by applying an integral approach at all stages of the aircraft design and production process:

• To reduce composite fuselage section weight in comparison with respect to conventional stringer scheme section due to wafer structure development.
• To reduce aircraft fuselage weight due to structure integrity increasing and replacement of conventional joint units by innovative micro-fastener joining elements.
• To raise fuselage section safety in worst case situations in comparison with respect to conventional stringer scheme section due to wafer structure high damage tolerance.
• To reduce aircraft manufacturing costs due to application of fully automated manufacturing process for regular and non-regular wafer structure with openings and embedded micro-fastener joints
