A method an apparatus for inducing spin, or rotation, in a dispersed payload of a non-spin guided projectile is taught. Rifling is applied to a cylindrical surface of a projectile casing. The rifling engages a member on a payload, which may be a bulkhead, as the payload is expelled from the projectile casing. The rotation imparted to the payload causes the dispersed projectile, grenades in the preferred embodiment, to form a spiral pattern that provides a more uniform coverage of the target area as compared to the prior art.
1. An apparatus for dispensing munitions from a non-spin stabilized projectile, comprising: a casing having a rifled cylindrical portion; a payload slideably located within said casing, said payload having a member engaging said rifled cylindrical portion, and a gas powered arrangement for expelling said payload from said casing thereby imparting rotation of said payload with respect to said cylindrical portion by said rifling and for directly expelling said munitions from said payload. 2. The apparatus of claim 1 wherein said arrangement for expe...
