Abstract
The invention discloses a base bleed shrapnel of a howitzer. The shrapnel comprises a fuse (1), a fighting part and a base bleed device, wherein a gas hole (7) is arranged at the bottom of the base bleed device, a base bleed medicine (5) is arranged inside the base bleed device, the fuse (1) is arranged on the head portion of the base bleed shrapnel, the base bleed device is arranged on the tail portion of the base bleed shrapnel, and the fighting part is arranged between the fuse (1) and the base bleed device. During the flight course of the base bleed shrapnel, the gas generated by burning of the base bleed medicine (5) is discharged from the gas hole (7). According to the base bleed shrapnel, the base bleed device is arranged at the shrapnel tail, during emitting, base bleed grain is lighted by propellant powder flame, and projectiles fly out of a muzzle and get a preset primary speed. Due to the exhausting action of the base bleed grain, the pressure at the shrapnel bottom is increased during flight of projectiles, the resistance at the projectile bottoms is reduced greatly and the range is increased.

The accompanying drawing explanation
in order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
fig. 1 is the schematic diagram according to an embodiment of end row's howitzer of howitzer of the present invention;
wherein: 1-fuse; 2-bursting charge; 3-body; 4-bearing band; The agent of 5-bottom drainage drug; 6-end row's housing; 7-pore; 8-dividing plate.
The specific embodiment
with reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention wherein is described.Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.Below in conjunction with figure and embodiment, technical scheme of the present invention is carried out to many-sided description.
at present, the ammunition that howitzer uses mostly is common howitzer, and range is nearer, can't meet some specific combat duty.The principle of end row's howitzer is to increase a gas combustion apparatus at projectile tail, and the projectile tail rarefaction is filled in the combustion gas of discharging with it, effectively reduces the pressure differential of bullet and projectile tail, is that base drag reduces greatly, and then has improved range.The base bleed range expansion rate is in 25%～40% left and right.During emission, propellant powder flame ignition base bleed grain, the bullet gun muzzle that flies out obtains predetermined initial velocity.Due to the scavenging action of base bleed grain, bullet is increased in the flight course base pressure of being hit by a bullet, the bullet base drag reduces and then increases range greatly.
at present, base bleed grain has two kinds, composite medicine formulation and fireworks medicament type, composite medicine formulation base bleed grain combustion speed is told somebody what one's real intentions are, density is less, usually need independently igniter, these shortcomings are all not too favourable to the design of drag-reduction effect and general structure coupling, and there will be during release and taken out the phenomenon of going out near gun muzzle.Bottom row device is arranged housing and, with two kinds of forms of row's housing at the bottom of grate, arranges housing with the end of grate and there will be the situation that causes base bleed grain work failure because of phenomenons such as grate are cracked, come off when shooting at the bottom of monoblock type is arranged.
fig. 1 is the schematic diagram according to an embodiment of end row's howitzer of howitzer of the present invention.As shown in the figure: end row's howitzer of howitzer comprises: fuse 1, warhead and bottom row device.The bottom of bottom row device 6 arranges pore 7, and bottom drainage drug agent 5 is set in bottom row device.Fuse 1 is arranged on the head of end row's howitzer.Bottom row device is arranged on the afterbody of end row's howitzer.Warhead is arranged between fuse 1 and bottom row device.In the process of end row's howitzer flight, the gas that bottom drainage drug agent 5 burnings produce is discharged by pore 7.
according to one embodiment of present invention, bottom drainage drug agent 5 is fireworks medicament, and fireworks medicament adopts solid overall structure.Bottom row device comprises end row's housing 6, and the end material of row's housing 6 is the 58SiMn steel, and end row's housing 6 adopts monolithic construction.
according to one embodiment of present invention, warhead comprises: body 3 and be arranged on the bursting charge 2 in body 3, and body 3 is with end row's housing 6 for being fixedly connected with, and pore 7 is arranged the outside of howitzer the end of towards.The material of body 3 is the 58SiMn steel; Bursting charge 2 is the TNT explosive.Bursting charge 2 also can need according to fighting the high explosive of filling other types to kill and wound demolition effect to improve bullet.
according to one embodiment of present invention, on the body of rifle cannon shell, be pressed with bearing band, during emission, bearing band embeds rifling, makes the bullet High Rotation Speed, guarantees that projectile flight is stable.In the junction of body 3 and end row's housing 6 and at the outer surface of body 3, bearing band 4 is set.
according to an embodiment, body 3 has the dividing plate 8 that bursting charge 2 and bottom drainage drug agent 5 are separated, the i.e. base plate of body 3.In the position of dividing plate 8 and at the outer surface of body 3, bearing band 4 is set.The end one end of row's housing 6 is threaded with body 3.
according to one embodiment of present invention, fuse 1 is DRL12 or PML12 contact fuze.End row howitzer is to adapt to row's howitzer at the bottom of 105 millimeters howitzers of 105 millimeters howitzers.
the end of the present invention row's howitzer is simple in structure, fuse, warhead and bottom row device three parts, consists of.But fuse adapted DRL12/PML12 contact fuze, warhead is comprised of body and bursting charge, airframe material adopts the 58SiMn steel, and the body structure design adopts the structural design that bearing band is arranged on to the dividing plate place between body and end row, thereby has improved body intensity.
in the bottom row device design, fireworks medicament is used in the bottom drainage drug agent, and combustion speed is high, capacity is large, density is large, does not need independently igniter, and these characteristics are favourable to drag-reduction effect and the design of general structure coupling.And base bleed grain adopts solid overall structure, and adopt the section combustion system; End row's housing adopts monolithic construction, avoids occurring that because the grate design is unreasonable grate is cracked, obscission.Relative other long-range missiles, the simple in structure of howitzer arranged at the end of the present invention, as long as install exhaust apparatus additional in the bullet bottom, basically do not reduce the payload (warhead quality) of bullet, thereby can not make power reduce.Due to reducing of air drag, thereby increased range.
description of the invention provides for example with for the purpose of describing, and is not exhaustively or limit the invention to disclosed form.Many modifications and variations are obvious for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present invention and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment with various modifications that the present invention's design is suitable for special-purpose.
