Abstract
An embodiment of the bomb casing (1) defines a generally conical nose portion (2) and a cylindrical body portion (3). At least one, and more preferably both, of the generally conical nose portion (2) and/or the cylindrical body portion (3) are formed from an additive manufacturing process, which is preferably cold-gas dynamic spraying of metal particles onto a support member. In one embodiment, the generally conical nose portion and cylindrical body portion are integrally formed.
Claims5
A process for additively manufacturing bomb casings defining a generally conical nose portion and a cylindrical body portion, the process including using cold-gas dynamic spraying equipment configured for spraying of metal particles entrained within a gas stream emanating from at least one nozzle to additively manufacture at least one of the generally conical nose portion and/or the cylindrical body portion of the bomb casing, wherein the metal particles as deposited onto a support member form interlaced layers extending in a circumferential direction, wherein a separation distance between adjacent layers is defined by a spray path overlap of the nozzle during cold-gas dynamic spraying of the metal particles forming the adjacent layers and wherein the spray path overlap between adjacent layers is between 30% and 60% of a spray path overlap that would result in minimal overlapping of the two adjacent layers.
