Special Issue Information

Dear Colleagues,

The over 30-year old additive manufacturing (AM) technology has re-emerged in recent years as one of the top ten disruptive technologies of this decade and as a core component of the industry 4.0 technology ecosystem. Known also as 3D printing, additive manufacturing has had a profound impact on design and production capability and is expected to revolutionize the global manufacturing landscape. The technology that was introduced as a prototyping solution for the manufacturing sector has matured enough to produce 3D-printed engines (GE Aviation), 3D-printed fuel nozzles (CFM’s LEAP engine), a 3D-printed subscale submarine, and other applications impacting significantly the aerospace and defence sectors.

In recent years, modern additive manufacturing has grown exponentially in terms of what can be achieved. In 2016, the AM industry reached the US$5.1 billion mark and is estimated to generate US$21 billion revenue worldwide by 2020 with a 34% CAGR (compound annual growth rate) by 2022.  In the aerospace industry, there is evidence that the technology has moved from prototype to certified and expected changes in products through the use of AM will create opportunities for innovation and revenues.

Additive manufacturing faces significant challenges to its wider adoption in the industry; challenges exist in complex geometry parts printing, part qualification and certification, material and machine selection, economic advantages, health and risks, tracking parts to ensure regulatory compliance, and part size and material limitation.  These are only 7 challenges experienced by the technology. To harness the potential of this technology and enable its wider acceptance in the industry, it is of significant importance to understand the growing importance of additive manufacturing in this digital age. This Special Issue addresses the fundamental aspects of the technology and how it is changing (its impact on) the aerospace and defence landscape. In addition, it welcomes submissions (reviews or otherwise) on the broader range of topics including (a) health and safety, (b) materials, (c) design optimization, (d) modelling and simulation, (e) supply chain, (f) quality assurance and control, (g) cybersecurity, (h) and in-service support.

This paper introduces a numerical tool developed for the design and optimization of axial-symmetrical hybrid composite/metal structures. It is assumed that the defined structures are produced by means of two different processes: Additive Layer Manufacturing (ALM) for the metallic parts and Filament Winding (FW) for the composite parts. The defined optimization procedure involves two specific software: ANSYS and ModeFrontier. The former is dedicated to the production of the geometrical and FE models, to the structural analysis, and to the post-process, focusing on the definition of the Unit Cells for the modelling of the metal part. The latter is dedicated to the definition of the best design set and thus to the optimization flow management. The core of the developed numerical procedure is the routine based on the Ansys Parametric Design Language (APDL), which allows an automatic generation of any geometrical model defined by a generic design set. The developed procedure is able to choose the best design, in terms of structural performance, changing the lattice metallic parameters (number of unit cells and their topology) and the composite parameters (number of plies and their orientation). The introduced numerical tool has been used to design several hybrid structures configurations. These configurations have been analysed in terms of mechanical behaviour under specific boundary conditions and compared to similar conventional metal structure. Full article
