Abstract
Official abstract text for this publication.
The invention relates to a projectile ( 6 ) provided with a slipping rotating band ( 1 ) which is designed for firing from a weapon system with a rifled barrel. The rotating band ( 1 ) comprises an inner ring ( 2 ) and an outer ring ( 3 ) that seals against the barrel. The outer ring is fitted on the outer surface of the inner ring and the inner ring is slippably fitted on the projectile. The rotating band ( 1 ) is configured to remain fitted on the projectile ( 6 ) from launcher to target by virtue of the fact that the inner ring ( 2 ) is made of fibre-reinforced polymer composite or particle-reinforced polymer composite, or fibre-reinforced metal matrix composite or particle-reinforced metal matrix composite. The invention also relates to a slipping rotating band ( 1 ) and to a method for producing a slipping rotating band ( 1 ) in which the outer ring ( 3 ) is affixed to the inner ring ( 2 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A projectile which comprises a slipping rotating band designed for firing from a weapon system with a rifled barrel, which rotating band comprises an inner concentric ring and an outer concentric ring that seals against the barrel, which outer ring is fitted on the outer surface of the inner ring and which inner ring is slippably fitted on the projectile, the outer ring, which seals against the barrel, is affixed to the inner ring, and the inner ring sl…
