Special Issue Information

Dear colleagues,

The use of additively manufactured metals by the aerospace industry has enjoyed a continuous, fast growth over the past ten years. In effect, this has substantially increased the research and development activity across a wide array of topics, such as:

  • Development of new aerospace metal alloys for fabrication via additive manufacturing (AM) methods (laser powder bed fusion, direct energy deposition, jet binding, fused filament fabrication, etc.);
  • Characterization of the mechanical and physical properties of aerospace AM alloys;
  • Modelling and prediction of the mechanical performance of aerospace AM alloys (static strength, high and low cycle fatigue, anisotropy, etc.);
  • Design and optimization of the mechanical properties, geometry, and weight of aircraft and spacecraft parts fabricated via metal AM;
  • Qualification and certification of AM alloys and parts for use in aircraft and spacecraft;
  • Development and optimization of metal AM methods aiming to improve quality and productivity in aerospace manufacturing;
  • Development of metal AM solutions for the sustainment of civil and military aircraft.

This Special Issue on “Metal Additive Manufacturing for Aerospace Applications” aims to identify key advances achieved by the research and industry community in the various fields associated with these topics. Original research papers and comprehensive reviews, including case studies on aerospace applications, are welcomed.

We are looking forward to receiving your submissions.

Additive manufacturing (AM) technology has a potential to improve manufacturing costs and may help to achieve high-performance aerospace structures. One of the application candidates would be a wind tunnel wing model. A wing tunnel model requires sophisticated designs and precise fabrications for accurate experiments, which frequently increase manufacturing costs. A flutter wind tunnel testing, especially, requires a significant cost due to strict requirements in terms of structural and aeroelastic characteristics avoiding structural failures and producing a flutter within the wind tunnel test environment. The additive manufacturing technique may help to reduce the expensive testing cost and allows investigation of aeroelastic characteristics of new designs in aerospace structures as needed. In this paper, a metal wing model made with the additive manufacturing technique for a transonic flutter test is studied. Structural/aeroelastic characteristics of an additively manufactured wing model are evaluated numerically and experimentally. The transonic wind tunnel experiment demonstrated the feasibility of the metal AM-based wings in a transonic flutter wind tunnel testing showing the capability to provide reliable experimental data, which was consistent with numerical solutions.

Additive manufacturing (AM) technology has undergone an evolutionary process from fabricating test products and prototypes to fabricating end-user products—a major contributing factor to this is the continuing research and development in this area. AM offers the unique opportunity to fabricate complex structures with intricate geometry such as the lattice structures. These structures are made up of struts, unit cells, and nodes, and are being used not only in the aerospace industry, but also in the sports technology industry, owing to their superior mechanical properties and performance. This paper provides a comprehensive review of the mechanical properties and performance of both metallic and non-metallic lattice structures, focusing on compressive behaviour. In particular, optimisation techniques utilised to optimise their mechanical performance are examined, as well the primary factors influencing mechanical properties of lattices, and their failure mechanisms/modes. Important AM limitations regarding lattice structure fabrication are identified from this review, while the paucity of literature regarding material extruded metal-based lattice structures is discussed.
