摘要

1. Improvements introduced in projectiles subcaliber in grenades training, consisting of a sheath inside which are arranged in axial prosecution percussion elements and deflagration, with ported projectile, characterized in that the stabilizing area ported projectile is provided one tracer and axial continuity with it a firecracker of powder deflagrará the end of the combustion liner. 2. Improvements introduced in subcaliber projectiles in training grenade, all according to the preceding claim, characterized in that the firecracker powder is black powder. 3. Improvements introduced in subcaliber projectiles in training grenade, all according to the first claim, characterized in that between the tracer and the elements deflagration continuity space through which the action of deflagration reaches the tracer. 4. Improvements introduced in subcaliber projectiles in training grenade, all according to the third claim, characterized in that the space is created by continuity at least one hole in the rear of the projectile ported and at least one hole with elements separation elements deflagration and ported projectile. 5. Improvements to subcaliber projectiles in training grenade, all according to the fourth claim, wherein the opening in the rear of the projectile turn makes ported nozzle. 6. Improvements to subcaliber projectiles in training grenade, all according to the first claim, characterized in that between the tracer and the firecracker powder washer with a hole regulating the deflagration firecracker is available. 7.
