INVISIBLE PROJECTILE Russian patent published in 2017 - IPC F42B12/00 F42B12/76 F42B15/00 F41H3/00 H01Q15/00 

FIELD: weaponry and ammunition supplies.

SUBSTANCE: projectile contains a body, detonator and explosive, while the body is made of ceramics, around which concentric layers of stretched parallely underlying fibers are wound. Layer by layer the fibers are oriented at an angle of 0°, +45, -45° to the longitudinal axis of the projectile, fastened to each other by means of a polymeric binder, the fibers have a cross-section in the shape of an equilateral triangle, with the cross-sectional area of the fibers reducing layer by layer in the direction of the axis of the projectile and adjacent fibres being in contact with each other through facing edges. The body can be made from quartz, nitride or oxide ceramic materials and glass or basalt fibers can be used.

EFFECT: creation of a projectile with sufficient strength and improved high-explosive fragmentation characteristics.
