Abstract
A low-resistant bullet belongs to the field of ammunition used by weapon. An existing bullet head has a flat-bottom bullet tail, and the structure causes comparatively large flight resistance and reduces flight performance of the bullet head. The low-resistant bullet meets the principle of aerodynamics by adopting a pointed bullet tail, and ensures that gunpowder gas can effectively act on the bullet and produce enough thrust by additionally arranging a separated sabot, thereby improving flight performance of the bullet. The low-resistance bullet also has the advantages of simple structure, low cost and the like, and is mainly adaptable to bullets used by light weapons.
Description
Technical field
The utility model relates to a kind of weapons and ammunitions, particularly relates to a kind of bullet that can reduce flight resistance.
Background technology
Present employed bullet bullet afterbody is flat shape substantially, and adopting this structure mainly is the propulsive efficiency of powder gases in order to improve bullet and to move in gun barrel.But this structure can make bullet produce bigger eddy resistance when high-speed flight, influences the flying quality of bullet.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and a kind of bullet that can reduce flight resistance is provided, and improves the flying quality of bullet.
The lower resistance bullet comprises bullet, shell case, the fire in a stove before fuel is added, propellant powder, it is characterized in that: the head of bullet and afterbody are pointed; The bullet afterbody is equipped with at least two bullet holders.
Between described bullet head and the afterbody cylindrical section is arranged.
Described bullet holder inner surface and bullet afterbody fit tightly.
Described bullet depend on short round end to end the end place be concave panel.
The nonmetallic materials manufacturing is adopted in described bullet holder.
During the bullet emission, powder gases at first acts on the bullet holder.Because the bullet holder is subjected to the constraint of gun barrel wall in gun barrel, so the bullet holder can't break away from bullet, can only promote bullet and advance.When gun barrel was flown away from bullet and bullet holder, the bullet holder lost constraint, cooperated at centrifugal force, air drag, with bullet under the acting in conjunction of the external force such as component that the inclined-plane produces, and separated with bullet, and bullet then continues flight separately.
The utility model compared with prior art has the following advantages and good effect: because the bullet afterbody has adopted sharp structure, effectively reduce the eddy resistance that produces in-flight, improved the flying quality of bullet.The application of separate type bullet holder, but guaranteed that the powder gases useful effect is in bullet and produce enough thrust.The utility model is simple in structure, and is with low cost, is adapted to be mounted within on the various bullets to use.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
Fig. 2 is the structural representation of a kind of embodiment bullet of the utility model holder
Among the figure: 1, bullet 2, bullet holder 3, shell case 4, propellant powder 5, the fire in a stove before fuel is added
The specific embodiment
The lower resistance bullet comprises bullet 1, bullet holder 2, shell case 3, propellant powder 4, the fire in a stove before fuel is added 5, and the head of bullet 1 and afterbody are pointed, between a cylindrical section is arranged.The bullet afterbody is equipped with at least two bullet holders 2, forms an approximate circle cylinder.Bullet holder 2 is a concave panel near bullet tail end place, and bullet holder 2 inner surfaces and bullet 1 afterbody fit tightly.
During the bullet emission, powder gases at first acts on bullet holder 2. because bullet holder 2 is subjected to the constraint of gun barrel wall in gun barrel, therefore bullet holder 2 can't break away from bullet 1, can only promote bullet 1 advances. when gun barrel is flown away from bullet 1 and bullet holder 2, bullet holder 2 loses constraint, at centrifugal force, air drag, cooperate with bullet under the acting in conjunction of the external force such as component that the inclined-plane produces, separate with bullet 1,1 of bullet continues flight separately. because the head and the afterbody of bullet 1 are pointed, the aerodynamic principle, reduce the eddy resistance of bullet 1, improved the serviceability of ammunition.
