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 center, 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.
