Manufacturing of Integral Stiffened Skin Panels

Project description

High-quality, environmentally friendly aircraft cargo doors

Exorbitant manufacturing costs and environmental pollution are the two main challenges facing metallic aircraft cargo doors. The EU funded MISSP project aims to solve these by developing cheaper and greener structures for all stiffened skin panels. Harnessing advanced materials, manufacturing techniques, and design concepts, MISSP will tackle the industry’s pressing challenges head-on. Through the replacement of chemical milling with flat mechanical machining and the integration of components to reduce assembly processes, this project will offer a paradigm shift in manufacturing. Comprising three pivotal technical work packages, followed by a comprehensive cost and performance analysis, MISSP promises a transformative solution. The project will pave the way for high-quality, environmentally friendly aircraft cargo doors that will revolutionise the industry.

Objective

MISSP (Manufacturing of Integral Stiffened Skin Panels) project aims at proposing new manufacturing concepts for metallic aircraft cargo doors. The main objective of this project will be to develop cheaper and greener structures as an alternative to CFRP doors but also applicable for any stiffened skin panel structure. This will be made possible by the use of advanced materials, manufacturing techniques and design concepts. Expensive and polluting chemical milling operations shall be replaced by flat mechanical machining, while multi-parts riveted components shall be replaced by more integrated structures reducing the number of parts and the time-consuming mechanical riveting assembly processes
The project will be divided into 3 main technical work packages, followed by a cost and performance analysis. The first work package shall focus on the manufacturing of the external door skin with the aim of replacing the chemically milled pockets by mechanically machined ones. Both stretch-forming on tailored tool blocks and high energy hydroforming alternative will be investigated. In the second work package, stringers shall be integrated to the Al-Mg-Sc 5028 skin by flat welding (FSW or LBW) followed by creep forming. Finally, the third package shall be dedicated to the manufacturing of an integral structure, drastically limiting the number of assembly operations. To this aim, an innovative solution is proposed: a plate shall be deformed by high energy hydroforming and subsequently machined into the final cargo door integral structure.
To support the advanced manufacturing technologies proposed in this challenging project, use shall be made of numerical modelling that will help designing appropriated tools and optimizing process parameters to achieve high quality demonstrators that shall be delivered to the topic manager.
