摘要：The present invention relates to a method and a device for improving—at leastin part—the external ballistieds of primarily the type of artillery shells () that are fin-stabilised in their trajectory towards the target and thus have a slipping plastic drivingband () which, during firing of the said shell from a designated barrel, constitutes the
shell's direct contact with the inside of the barrel. The problem that it is the function ofthe present invention to resolve is that the slipping plastic driving band () normallydetaches immediately outside the muzzle of the barrel used for firing, thereby leaving anopen groove () that causes distrubing turbulence which is detrimental to the flight of thesaid shell. The solution to the problem herein proposed is based on a ring-shapedspring-loaded device () arranged between the driving band () and the bottom of thedriving band groove () and which device is held pressed against the bottom of the saiddriving band groove as long as the driving band () is in position but as soon as it detachesfrom the said driving band groove the said device deploys to re-assume a pre-determined original shape which completely fills the driving band groove () up to andlevel with the outer surface of the shell ().
