Abstract
The utility model discloses a base bleed grenade of a howitzer. The base bleed grenade of the howitzer comprises a fuse (1), a payload and a base bleed device, a gas hole (7) is arranged at the bottom of the base bleed device, base bleed powder (5) is arranged in the base bleed device, the fuse (1) is arranged at the head of the base bleed grenade, the base bleed device is arranged at the tail of the base bleed grenade, and the payload is arranged between the fuse (1) and the base bleed device. Gas generated through burning of the base bleed powder (5) is discharged through the gas hole (7). The base bleed device is arranged at the tail of the base bleed grenade. When the base bleed grenade is launched, flame of propellant powder lights a base bleed grain, and the grenade flies off a muzzle to obtain predetermined initial speed. Due to exhaust effect of the base bleed grain, pressure at the bottom of the grenade is increased in a grenade flying process, resistance at the bottom of the grenade is reduced greatly, and firing range is increased.

The accompanying drawing explanation
in order to be illustrated more clearly in the utility model embodiment 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 embodiment more of the present utility model, 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 utility model;
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 utility model is described more fully, exemplary embodiment of the present utility model wherein is described.Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.Below in conjunction with figure and embodiment, the technical solution of the utility model 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 utility model.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 an embodiment of the present utility model, 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 an embodiment of the present utility model, 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 an embodiment of the present utility model, be pressed with bearing band on the body of rifle cannon shell, 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 an embodiment of the present utility model, 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 utility model 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 utility model, 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 present utility model provides for example with for the purpose of describing, and is not exhaustively or by the utility model to be limited 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 utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment with various modifications that the utility model design is suitable for special-purpose.
