A permeable barrel for accelerating a projectile is provided. The barrel includes a plurality of holes through which gas can be injected to generate a gas cushion for the projectile. The gas cushion prevents any contact between the projectile and the barrel walls. Also the gas cushion helps to keep the projectile centered in the barrel throughout its travel.
