at the bottom of the recessed device in the end of the recessed howitzer in the end of howitzer of the present invention makes bullet, the low pressure strength of vortex weakens, and partial vacuum zone is filled by air, thereby improves the pressure of bullet bottom, and base drag is reduced, and then increases range.
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 the recessed howitzer in the end of howitzer of the present invention;
wherein: 1-fuse; 2-bursting charge; 3-body; 4-bearing band; The recessed device in 5-end; 6-groove.
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.
fig. 1 is the schematic diagram according to an embodiment of the recessed howitzer in the end of howitzer of the present invention.As shown in the figure: recessed howitzer comprises at the end of howitzer: the recessed device 5 in fuse 1, warhead and the end; The bottom of the recessed device 5 in the end has groove 6; Fuse 1 is arranged on the head of the recessed howitzer in the end; Recessed device 5 is arranged on the afterbody of the recessed howitzer in the end at the end, and groove 6 is towards the outside of the recessed howitzer in the end; Warhead is arranged between the recessed device 5 of fuse 1 and the end.
the ammunition that howitzer uses in the world now mostly is common howitzer, and range is nearer, can't meet some specific combat duty, and the recessed howitzer in the end of howitzer adopts the recessed structure in the end to gain the name because of it in the bullet bottom.The main body of the recessed howitzer in the end is similar to flat howitzer, has replaced gradually at present flat howitzer.The main feature of the recessed howitzer in the end is that range increases, and fire accuracy improves.Bullet after the gun muzzle that flies out, because of the recessed device in the end of bottom make bullet at the bottom of the low pressure strength of vortex weaken, partial vacuum zone is filled by air, thereby improves the pressure of bullet bottom, and base drag is reduced, and then increases range.
according to one embodiment of present invention, warhead comprises: body 3 and be arranged on the bursting charge 2 in body 3.The material of body 3 is the 58SiMn steel; Bursting charge 2 is the TNT explosive.Body 3 with the recessed device 5 in the end for being fixedly connected with; 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.
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 the recessed device 5 in the end and at the outer surface of body 3, bearing band 4 is set.According to an embodiment, body 3 has the dividing plate (or being the base plate of body 3) of isolation between the recessed device 5 of bursting charge 2 and the end, and bearing band 4 also can arrange the dividing plate place.
the head of the recessed device 5 in the end is threaded with body 3.The material of the recessed device 5 in the end is the 58SiMn steel.Fuse 1 is DRL12 or PML12 contact fuze.For the design feature of this bullet, also full bullet can be designed to recessed howitzer at the bottom of monoblock type, both recessed device has not been connected with body by screw thread at the end, but, when processing body 3, directly processes the recessed device 5 in the end, and the tail end of body 3 has groove.
according to one embodiment of present invention, the recessed howitzer in the end is to adapt to recessed howitzer at the bottom of 105 millimeters howitzers of 105 millimeters howitzers.Present stage, the recessed howitzer in the end of countries in the world equipments mostly was recessed howitzer at the bottom of monoblock type, multiplex on the howitzer of 122 millimeters above bores of bore, do not occur temporarily the recessed howitzer in the end on 105 millimeters bore howitzers.
at present, the ammunition that howitzer, particularly 105 millimeters howitzers use mostly is flat standard howitzer, plays shape poor, range closely and fire accuracy not high.At the bottom of 105 millimeters, recessed howitzer plays shape with crossing to optimize, and changes the bullet Mass Distribution, the range of bullet can be improved to 20%, and can further improve fire accuracy.And, in the raw-material selection of the recessed device of body and the end, for example the 58SIMN steel, to improve the intensity of body and the recessed device in the end, stop to occur that the recessed intensity of body and the end can not meet the situation that shooting requires.
recessed howitzer is simple in structure at this end, recessed device three parts in fuse, warhead and the end, consists of.Warhead is comprised of body and bursting charge, and body structure design adopts the structural design that bearing band is arranged on to body and the end dividing plate place between recessed, thereby has improved body intensity.
the recessed howitzer in this end is arranged on body and the end dividing plate place between recessed by bearing band, thereby has improved body intensity.Because of the growth of bullet, although end concave portion is arranged, bullet coyote hole length does not shorten, simultaneously, because bearing band is arranged on body and the end dividing plate place between recessed, body intensity is improved, can make to play the wall attenuate, thereby increase the dynamite charge amount, improved the power of bullet.
after adopting the recessed structure in the end, reach at the bottom of bullet, full bullet length can surpass the flat howitzer of spin stabilization formula.Due to the growth of bullet, bearing band plays bottom surface by close, thereby has increased guidance part, has improved the correctness of Projectile Motion in Bore, is conducive to improve the outer trajectory performance.The end recessed structural formula bullet Mass Distribution is more concentrated, the equator moment of inertia of bullet reduces with the ratio of polar moment of inertia, and the barycenter of whole bullet reach, behind Center of Pressure, move, make again turning torque in-flight reduce, the flight stability that these all are conducive to bullet, reduce air drag, improved the attack precision of bullet.
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.
