Bullet bottom separation mass-reducing range-extending cannonball
Technical Field
The invention relates to the field of middle trajectory, in particular to a projectile with separated projectile bottom and reduced mass and increased range.
Background
The projectile bottom structure of the artillery projectile mainly has the main functions of bearing high overload during launching, protecting a projectile damage part from being damaged by high chamber pressure, and therefore, the structure is thicker and heavier; and the bullet bottom is also provided with a copper sealing bullet belt generally, and the mass of the bullet bottom becomes a negative mass which consumes the flying kinetic energy of the bullet when the bullet flies. That is, the projectile bottom does not play any positive role in the projectile flying process after the projectile leaves the bore, but rather reduces the flying speed of the projectile to a certain extent due to the weight of the projectile bottom. In order to pursue the end-point damage effect with a longer range, bottom row drag reduction and fixed emission range extension are common technical means, however, according to public data, the purpose of range extension achieved by a design method for reducing negative quality is not found.

In order to achieve the purpose, the invention provides the following scheme:
the invention provides a bullet bottom separation mass-reducing range-extending cannonball, which sequentially comprises a warhead, a solid engine and a separation bullet bottom mechanism; the solid engine comprises a solid engine shell, a solid engine cartridge, a spray pipe for spraying combustion products and a solid-state igniter; the solid engine cartridge is disposed inside the solid engine housing.
The separating bottom ejection mechanism comprises a bottom ejection, a bottom row shell and a bottom row igniter; the outlet of the spray pipe and the bottom row shell are both arranged in the bullet bottom; the bottom row shell is internally provided with a grain containing propellant; one side of the solid engine shell is fixedly connected to the warhead, and the other side of the solid engine shell is connected with the bottom end of the bullet bottom.
Preferably, the base row housing is disposed between the nozzle and the bullet base.
Preferably, the other side of the solid engine shell is sleeved or bonded at the bottom end of the bullet bottom.
Preferably, a bearing is arranged between the solid engine shell and the bullet bottom, and the bearing is fixedly arranged on the solid engine shell. In the process of launching the shell, the separation bullet bottom mechanism rotates at a high speed, and the bullet and the separation bullet bottom mechanism are connected through the bearing, so that the bullet rotates at a low speed under the action of inertia, the rotating speed of a bullet muzzle is effectively reduced, and the control on the bullet in the later period is facilitated. Preferably, the bottom end of the solid engine housing is in interference fit with the bottom end of the bullet bottom.
Preferably, the outer side of the bullet bottom is provided with a bullet belt which can bear high-temperature and high-pressure gas impact, the bullet belt is embedded into rifling during launching, gunpowder gas is sealed, the bullet rotates at a high speed, and stable flight of the bullet is guaranteed.
The invention discloses the following technical effects: the bottom discharge charge and the fuel gas generated by the charge of the solid engine are utilized to separate the bottom separating mechanism from the projectile, and the solid engine continues to push the rest of the payload to fly; the negative mass of the projectile in the flying process is effectively reduced by separating the projectile bottom mechanism, and the aim of further flying distance of the projectile under the same charging condition is fulfilled. The design method for separating the projectile bottom effectively reduces the negative mass of the projectile in the air flight process, is simple and convenient to realize, and has the advantages of safety, reliability and low use requirement.
