摘要

The present invention relates to a projectile (11) extending along an axis X between two ends (12, 13), the projectile being intended to be positioned in a barrel (18) of substantially cylindrical shape of axis X. According to the invention, the projectile (11) comprises: .cndot. a hollow part (14) at its centre, opening onto a first (12) of the two ends (12, 13) of the projectile (11) and intended to receive a compressed fluid, .cndot. a plurality of vents (15) passing through the projectile (11) from the hollow part (14) substantially perpendicular to the axis X and with a substantially radial outlet which is intended to expel the compressed fluid substantially at a tangent to the projectile (11). The invention also relates to the barrel (18) and to a launch device comprising a projectile (11) and a barrel (18) according to the invention.
