Abstract
The utility model belongs to a bullet which can save material and can stably fly. The bullet is characterized in that the bottom of the bullet is provided with a concave cavity; the bottom of the cavity is positioned at the center of gravity of the bullet or the front end of the center of gravity; the concave cavity can be used as partial charge chamber, which can shorten the chamber length of a charge cartridge and a shooting tool, and material can be saved; armament gas in the after-effect period acts on the bottom of the cavity to lead the bullet to stably fly.
Description
The utility model belongs to that a kind of have can be for the bullet of rifle or big gun emission universal architecture, exactly is a kind of material but also bullet that can stabilized flight not only saved.
Present its cartridge case of bullet that uses and to penetrate the tool cartridge chamber long relatively; It is poor that bullet is launched the thorax rear stability.
The utility model purpose provides a kind of concave bottom cavity bullet, makes it can save material, again can stabilized flight.
The utility model purpose is achieved in that in the bullet bottom to be had in the structure of a cavity, is arranged on the center of gravity place or center of gravity (bullet direction) front end of bullet at the bottom of the chamber with cavity.Even have one to cross at the bottom of the chamber and bullet is truncated into two partly perpendicular to the plane of bullet axle: solid part and cavity partly, when being arranged on the bullet center of gravity at the bottom of the chamber, two partly quality equate; When the center of gravity front end, solid part quality is less than cavity part quality at the bottom of the chamber.This structure bullet is identical if compare the axial distribution of its quality with isometrical isometric common bullet.
Because above feature is arranged, the cavity of bullet can be used as the some of propellant powder coyote hole, thereby suitably shortens the length of propellant powder cartridge case and emission tool under the situation that does not change chambervolume, to save whole weapon material.
Because above feature is arranged, after bullet was launched thorax, the impulsive force of after effect period powder gases acted directly at the bottom of the chamber of bullet cavity again, with flight stability in the middle trajectory of guiding bullet before breaking away from the powder gases effect.
Owing to adopt such scheme, can when saving material, improve self stability, curved cavity is simple, and is applied widely.
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing
Accompanying drawing is the utility model embodiment sectional side elevation
Among the figure 1, at the bottom of the bullet 2, cavity 3, chamber
In the bottom of bullet 1 cavity 2 is arranged among the figure, there are two kinds of embodiments 3 position at the bottom of the chamber: one is at the center of gravity place of bullet; It two also can be at the front end of bullet center of gravity (bullet direction).
