Abstract RU 2527250 C2

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to artillery, ammunition, particularly, to reduction of base drag of projectile or bullet. Body has one channel connecting lateral surface and body bottom part. Said body features, primarily, ogival or sharpened nose. Proposed method consists in creating rarefaction body bottom part with suction of medium, including the boundary layer, from body bottom part via said channel.

EFFECT: reduced base drag.
