Abstract (en)

A projectile propulsive device for propelling a projectile under the action of fluid under pressure comprises a barrel (11) having an axial bore in which a projectile (53) to be propelled is in use located, and a pressurised fluid supply for supplying fluid under pressure to the bore of the barrel (11) through a supply aperture (30) in the barrel (11) whereby in operation fluid under pressure from the supply flows through the supply aperture (30) to act on the base of the projectile to bring the projectile in the barrel to a predetermined axial velocity. To impart spin to the projectile (53), fluid under pressure from the supply is directed into the bore of the barrel (11) through the supply aperture (30) tangentially or partially tangentially with respect to the bore of the barrel (11).
