Description
Technical field
The invention belongs to bullet equipment technical field, be specifically related to a kind of bottom deflation type caseless cartridge.
Background technology
There is shell-type bullet since appearance, employ for many years, but improve extremely limited.There is the maximum drawback of shell bullet to be that the existence of shell case adds the fault rate of firearms, also add the weight of firearms and size and production difficulty, the ammunition carrying amount of combat troop is restricted, affects fighting capacity.Because there are all deficiencies of shell bullet, a lot of country has all carried out the research of caseless cartridge.For ensureing caseless cartridge use safety, moistureproof thermal insulation, moth-proof and mould-proof, anti-aging, wear-resisting durable, a lot of experiment group carries out experiment for a long time, but up to the present, the ripe and caseless cartridge only having the G11 rifle of Germany supporting that equips our troops of small lot of Technical comparing.The advantage of G11 is that the height that the little weight of high firing rate and burst firing precision and accuracy and caseless cartridge and size are brought takes bullet amount.But shortcoming also clearly, it is exactly the overheated spontaneous combustion problems brought of firearms after sustained fire.Shell case is sent out in conventional gun attack rear can absorption portion heat, bore is heated up comparatively slow, and has the existence of shell case, also play buffer action.Even if G11, also spontaneous combustion problems to be solved by rotary firebox type gunlock and high ignition temperature propellant.The reason that G11 only equips our troops on a small quantity is exactly still lack confidence to ammunition cooling.Nineteen fifty-nine, the U.S. starts a series of caseless cartridge Test And Research Work, but result is all unsatisfactory, finally confirms in 1974 that spontaneous combustion problems can't resolve and be abandoned.China also once developed caseless cartridge, but because great number of issues stopped development in 1973 years.
Summary of the invention
The object of the present invention is to provide a kind of bottom deflation type caseless cartridge, after solving existing caseless cartridge sustained fire, cause the overheated problem causing bullet spontaneous combustion of rifle body.
The technical solution adopted in the present invention is: bottom deflation type caseless cartridge, comprise the bullet that sets gradually from top to bottom by first, play core, piston cylinder, connecting rod and projectile tail, the outside of piston cylinder is sheathed with spring, the arranged outside of connecting rod has columnar body, inwall one circle along body is provided with baffle plate, the upper end of body is connected by the lower end of first with bullet, and the one end playing core is positioned at piston cylinder; One end of spring is positioned at the downside on edge on piston cylinder, and the other end is positioned at the upside of baffle plate, and the bottom of projectile tail is provided with the fire in a stove before fuel is added and fills chamber, and the outside of projectile tail is provided with vent; Form propellant powder between body and connecting rod, projectile tail and fill chamber, the fire in a stove before fuel is added is filled in chamber and is filled with the fire in a stove before fuel is added, and propellant powder is filled inside, chamber and is filled with gunpowder.
Feature of the present invention is also,
The lower end of piston cylinder and the both sides being positioned at connecting rod are provided with passage.
Vent is provided with two, and lays respectively at the both sides of projectile tail, and vent is filled chamber respectively and filled chamber with propellant powder and be communicated with the fire in a stove before fuel is added.
The invention has the beneficial effects as follows: remain without medicine shell when bottom of the present invention deflation type caseless cartridge is launched, simplify corresponding firearms structure, reduce firearms weight.Solve the easy spontaneous combustion of traditional caseless cartridge, duds rate is high, and the problem of moisture-sensitive, environment for use is extensive.The percussion of projectile tail can increase bullet lethality.Body is long-pending to be reduced with weight, increases allowance of ammunition.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in detail.
The invention provides a kind of bottom deflation type caseless cartridge, as shown in Figure 1, comprise the bullet that sets gradually from top to bottom by first 2, play core 1, piston cylinder 5, connecting rod 6 and projectile tail 7, the outside of piston cylinder 5 is sheathed with spring 9, the arranged outside of connecting rod 6 has columnar body 3, inwall one circle along body 3 is provided with baffle plate 4, and the upper end of body 3 is connected by the lower end of first 2 with bullet, and the one end playing core 1 is positioned at piston cylinder 5; One end of spring 9 is positioned at the downside on edge on piston cylinder 5, and the other end is positioned at the upside of baffle plate 4, and the bottom of projectile tail 7 is provided with the fire in a stove before fuel is added and fills chamber 11, the outside of projectile tail 7 is provided with vent 8; Form propellant powder between body 3 and connecting rod 6, projectile tail 7 and fill chamber 12, the fire in a stove before fuel is added is filled in chamber 11 and is filled with the fire in a stove before fuel is added, and propellant powder is filled inside, chamber 12 and is filled with gunpowder.
As shown in Figure 2, piston cylinder 5 lower end and the both sides being positioned at connecting rod 6 are provided with passage 10.
As shown in Figure 3, vent 8 is provided with two, and lays respectively at the both sides of projectile tail 7, and vent 8 is filled chamber 11 respectively and filled chamber 12 with propellant powder and be communicated with the fire in a stove before fuel is added.
During use, bottom deflation type caseless cartridge enters chamber thorax, the fire in a stove before fuel is added is filled the fire in a stove before fuel is added of filling in chamber 11 and is pulled the trigger and fill gunpowder in chamber 12 by vent 8 propellant powder that ignites, the powder burning that propellant powder is filled in chamber 12 produces high temperature and high pressure gas, because projectile tail 7 cannot move backward by firearms restriction, gas just promotes body 3 and moves to muzzle direction, relative to body 3, piston 5 moves downward, spring 9 is caused to be compressed, when spring 9 is compressed to mechanical balance, piston 5 stops moving downward, now, projectile tail 7 no longer contacts with body 3, combustion gas is released, under the effect of high-pressure gas, bottom deflation type caseless cartridge opens projectile tail 7 and tells motion to muzzle.When caseless cartridge moves near muzzle, air pressure declines, and spring 9 resets, and pulls piston 5 and projectile tail 7 to make it to reset.After reset, body 3 is complete, at utmost can reduce the impact of air on trajectory and range etc.During bullet hit, bullet is a significant slowdown by first 2 and bullet core 1, and projectile tail 7 moves forward due to inertia, rush broken body 3 and piston 5 and even play core 1 and bullet by parts such as first 2, produce the fragment of some, disperse in objective body, great damage is caused to target, make it to lose fighting capacity.
Due to the existence of body 3, the gunpowder that propellant powder can be allowed to fill in chamber 12 is in a relatively stable interference-free environment, reduce spontaneous combustion and duds probability, occupation mode is roughly the same with conventional bullet, and the design of movable projectile tail 7 also add failing of bullet and power.
By the way, bottom of the present invention deflation type caseless cartridge, causes the overheated problem causing bullet spontaneous combustion of rifle body after solving existing caseless cartridge sustained fire.Bottom of the present invention deflation type caseless cartridge remains without medicine shell when launching, and simplifies corresponding firearms structure, reduces firearms weight.Solve the easy spontaneous combustion of traditional caseless cartridge, duds rate is high, and the problem of moisture-sensitive, environment for use is extensive.The percussion of projectile tail can increase bullet lethality.Body is long-pending to be reduced with weight, increases allowance of ammunition.
