1. A device for repairing erosion damage to a bore of a railgun with metal powder, said bore having a surface contour extending longitudinally of said railgun, said device comprising:
a housing having a configuration that conforms to the surface contour and an upstream face on a longitudinal end; a profilometer sensor mounted to said upstream face to measure depth of the erosion and indicate a divot in the bore that involves repair to match the surface contour; and a nozzle mounted to said upstream face to spray the metal powder from a reservoir within said housing in response to said divot indicated by said profilometer sensor. |
