Example Embodiment

[0015] The present invention will be described with reference to the drawings.

[0016] Such as figure 1 Shown is a charge structure for high chamber pressure artillery, including cartridge 1, primer 2, black powder pack 3, single camphor-11A-8 / 1 propellant 4, single base 5 / 7 propellant 5, nitrocellulose Cardboard 6 and hard paper cover 7. The cartridge 1 is a truncated cone-shaped shell with an open upper part. The primer 2 is fixed on the bottom surface of the cartridge 1, and the black powder pack 3 is fixed on the upper part of the primer 2. Single camphor-11A- The 8 / 1 propellant 4 is set around the inside of the cartridge 1, the single base 5 / 7 propellant 5 is set in the center of the cartridge 1, and the nitrocellulose cardboard 6 is set on the single camphor-11A-8 / 1 propellant 4 and 5 of the single-base 5 / 7 propellant, and in close contact with the two, the cardboard cover 7 is set on the upper part of the single-base 5 / 7 propellant 5; the cartridge 1 is brass with a thic...

Abstract

The invention discloses a charging structure for a high chamber pressure artillery. The charging structure includes a cartridge case, artillery primer, a black fire cartridge bag, single camphor-11A-8/1 propellant powder, single base 5/7 propellant powder, a nitrocotton paper board and a hard paper cover board; the cartridge case is a conical bench-type shell body with upper part opened, the artillery primer is fixedly arranged on the bottom surface of the cartridge case, the black fire cartridge bag is fixedly arranged on upper part of the artillery primer, the single camphor-11-A-8/11 propellant powder is arranged on the periphery of the inner part of the cartridge case, the single base 5/7 propellant powder is arranged at the center part of the inner part of the cartridge case, the nitrocotton paper board is arranged between the single camphor-11A-8/1 propellant powder and the single base 5/7 propellant powder and is tightly contacts with the single camphor-11A-8/1 propellant powderand the single base 5/7 propellant powder, and the hard paper cover board is arranged on the upper part of the single base 5/7 propellant powder. The charging structure has the characteristics that the structure is simple, operation is convenient, and uniformity is good, the purposes that ignition, fire transmission and combustion performance are improved, thus the gas production rate of whole charged powder is improved are achieved, thus ballistic performance is greatly improved, and the initial speed of a pill is improved.

Description

technical field [0001] The invention belongs to the technical field of projectile high-speed penetration tests, relates to a high chamber pressure artillery charge structure, in particular to a high chamber pressure artillery charge structure. Background technique [0002] Projectile high-speed penetration test is an important method for warhead development and protection engineering design to study the damage of high-speed ground-penetrating weapons to deeply buried solid targets. High-speed projectile launch has high requirements for the charge structure of artillery. It is necessary to meet the rapid increase of the gun bore pressure so that the projectile can obtain a sufficient extrusion pressure, and ensure that the charge can continue to burn in the bore to meet the requirements of loading the projectile to the preset speed. It is difficult for the commonly used charge structure to meet these two requirements at the same time, which makes it difficult to achieve the i...
