PROJECTILE AND BARREL INTENDED TO ACCOMMODATE SUCH A PROJECTILE

摘要

A projectile extending along an axis X between two ends, the projectile being positioned in a barrel of substantially cylindrical shape of axis X is provided. The projectile comprises: a hollow part at its centre, opening onto a first of the two ends of the projectile to receive a compressed fluid, a plurality of vents passing through the projectile from the hollow part substantially perpendicular to the axis X and with a substantially radial outlet to expel the compressed fluid substantially at a tangent to the projectile. The invention also relates to the barrel and to a launch device comprising a projectile and a barrel.

主权项

1. A projectile extending along an axis X between two ends, the projectile being positioned in a barrel of substantially cylindrical shape of axis X, the barrel comprising a first of two helical-connection elements, comprising:
a hollow part at its centre, opening onto a first of the two ends of the projectile to receive a compressed fluid, a plurality of vents passing through the projectile from the hollow part substantially perpendicular to the axis X and in a direction that has a radial component, to expel the compressed fluid substantially at a tangent to the projectile, a second of two helical-connection elements which is fixed in the hollow part of the projectile, the first and the second helical-connection elements forming a combined-movement mechanism to simultaneously generate a rotation about the axis X and a translation along the axis X of the projectile with respect to the barrel.
