RUAG Australia presents findings on additive metal technology solutions restoring load carrying capabilities for aircraft skin structures at the 18th AIAC conference at AVALON 2019

RUAG Australia’s internationally recognized authority on Supersonic Particle Deposition (SPD), Neil Matthews, is presenting the experimental results using SPD for repairs to restore the load carrying capacity of rib stiffened wing planks with simulated skin corrosion at the 18th Australian International Aerospace Congress (AIAC)....

The findings support the use of SPD technology, an additive metal manufacturing technology, as an innovative and reliable solution for restoring full structural functionality while potentially reducing the replacement times and costs associated with traditional approaches to skin corrosion repairs. The presentation takes place on Tuesday, 26 February 2019, during the 2019 Australian International Avalon Air Show week.

The study builds on the findings of a prior computational study into SPD repairs to corroded airframes. The experimental results reveal that SPD repairs to skin corrosion ensure the load carrying capability of the repaired structure to above proof load, by restoring the stress field in the structure. This is particularly important for aircraft that regularly operate under demanding conditions.

“This paper goes further in our efforts to provide proof that additive metal technology offers highly reliable repair methods to skin corrosion for maritime and military transport aircraft,” states Neil Matthews, Senior Manager Research and Technology, RUAG Australia.

“SPD technology also has the potential to provide significant cost savings, when compared to the complex, time-intensive and accepted common approach to these types of repairs to skin corrosion,” he adds.

The paper is the outcome of collaborative research with Monash University and is co-funded by the US Navy, Naval Air Systems Command (NASC).

Neil Matthews has won the AIAC Best Written Paper Award at the 2017 Australian International Aerospace Congress with another paper on SPD technology.

This year’s AIAC paper was previewed at the Applied Vehicle Technology Panel Research Workshop, sponsored by NATO’s Science & Technology Organization Collaboration Support Office on Corrosion Management, in Athens on 10 December 2018. The workshop, along with presentations from Australia’s Defence Science and Technology Group as well as RUAG’s collaborative partner, United States Naval Air Systems Command, was attended by over 150 representatives from NATO countries.
