ruag australia wins aiac best written paper award

March 12, 2019

RUAG Australia has proven that  the  use  of  Supersonic  Particle  Deposition  (SPD),  an  additive  metal  manufacturing technology, is a reliable solution for restoring full structural functionality to maritime and military  aircraft  skin  structures.  This  process  was  set  forth  in  the  Best  Written  Paper winning  entry  at  the  18th  Australian  International  Aerospace  Congress  (AIAC).  Entitled “Additive  Metal  Solutions  to  Aircraft  Skin  Corrosion”,  the  paper was  presented  by  RUAG Australia.

The findings  in  the  RUAG  Australia  paper  reveal  that  SPD  repairs  to  skin  corrosion  restore the stress field in the structure and ensure that the load carrying capability of the repaired structure is above  proof  load.  This  makes  the  technology  particularly  applicable  to  maritime  and  military aircraft,  whose  regular  operating  conditions  include  high  stress  performance  and  harsh environmental factors. 

The  research  results  also  show  that  SPD  technology  has  the  potential  to  reduce  the  costs  and replacement times associated with traditional approaches to aircraft skin corrosion repairs. In fact, the incidence of component repair, or replacement, is a critical issue for this category of aircraft.

The associated costs are seen to rise in conjunction with the intensity of the damage, the industry-accepted repair method and/or the turnaround times for accessing spares, when repair has been generally viewed as a non-viable solution.

“SPD  offers  highly  reliable,  cost  effective  and  time-sensitive  repair  solutions  to  complex  skin corrosion issues,” states Neil Mathews,  Senior Manager Advanced Technology and Engineering Solutions, RUAG Australia, and presenter of the Best Written Paper. “As our research continues to progress, and advancements in the scope of SPD applications expand, additive metal technology proves its very real advantages over traditional repair methods,” 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).
