Embodiment 1

[0037] Such as figure 1 As shown, the present embodiment provides a warhead body parameter adjustment device. It includes a warhead shell 1, and is characterized in that it also includes a counterweight ring 2, a counterweight fragment 3, and a locking device 4;

[0038] The shape of the warhead shell 1 is a first cylinder, the first cylinder of the warhead shell 1 is a revolving body, the axis of the revolving body of the warhead shell 1 is parallel to the horizontal plane, and the left end of the warhead shell 1 has a second A conical boss, the side generatrix of the first conical boss of the warhead shell 1 is an arc, and the outer cylindrical surface of the first cylinder of the warhead shell 1 has a first annular groove, the warhead The left end face of the first annular groove of casing 1 is the first left end circular table surface, and the left end diameter of the first left end circular table surface of warhead housing 1 is smaller than the right end diameter, and th...

Embodiment 2

[0069] The difference between embodiment 2 and embodiment 1 is:

[0070] In this embodiment, the ratio of the depth of the second outer V-shaped groove of the weight ring 2 to the diameter of the second circular through hole of the weight ring 2 is 1:6;

[0071] In this embodiment, the included angle between the busbar of the circular table surface at the fourth left end of the locking device 4 and the axis of the rotating body of the locking device 4 is 80°;

[0072] In this embodiment, the ratio of the depth of the first annular groove of the warhead shell 1 to the diameter of the first cylinder of the warhead shell 1 is 1:13;

[0073] Process ten inventions, wherein the difference in the moment of inertia of the center of mass of the warhead shell 1 is between 2% and 3%, the adjustment of the moment of inertia of the center of mass through the present invention, and finally through instrument detection, ten of the mass of the present invention The difference in the moment ...

Abstract

The invention discloses a warhead projectile body parameter adjusting device. A fourth ring body of a locking device is located in a second annular gap of a counterweight ring; a fourth left end circular truncated cone surface of the locking device is in contact with a second ring body of the counterweight ring located on a left group and compacts the second ring body of the counterweight ring located on the left group; a fourth right end circular truncated cone surface of the locking device is in contact with a second ring body of the counterweight ring located on a right group and compacts the second ring body of the counterweight ring located on the right group. According to the warhead projectile body parameter adjusting device, the mass of the warhead is adjusted by adjusting the diameters of the tungsten fragments; the rotating inertia of the warhead is adjusted by adjusting the annular distribution diameters of the tungsten fragments; the mass center of the warhead is adjusted by adjusting the position of the locking device; three projectile body parameters of the warhead can be adjusted at the same time, so that the three projectile body parameters meet the design requirements at the same time; the projectile trajectory precision is improved; and the target hitting probability of the warhead is improved.

Description

technical field [0001] The invention belongs to the technical field of adjusting devices, and relates to an airframe parameter adjusting device, in particular to an airframe parameter adjusting device for a warhead. Background technique [0002] The detonation warhead is the most common type of warhead. After the warhead is charged and exploded, a large number of fragments and explosion shock waves are generated, causing damage to vehicles, personnel, missiles, radars and other targets. [0003] Improving the conversion rate of charge energy to kinetic energy of fragments is the key way to enhance the penetration power of fragments. Wang Weizhan and others reported in the document "Conversion Rate of Charge Energy of Explosive Warhead to Fragment Kinetic Energy" (Blasting Equipment, April 2017, Vol. 46, No. 2, Page 26): The density of the fragment material increases, and the The overall kinetic energy increases. Therefore, the shell is made of aluminum and the fragments ar...
