The group of inventions relates to field of arm engineering, notably to the caseless ammunition and a mechanism that allows you to extract caseless ammunition reliably.
There are different constructions of caseless ammunition, when the bullet is inside the head space of the propellant charge, developed in Austria, 1983-1994, 1980-1986, France, Germany, 1974-1987, 1969-1975 the USA. The disadvantage of ammunition when a bullet is inside the head space is that there are complicated constructions of the weapon G11 Germany, the LSAT the USA, and there is also a possibility of self-ignition of ammunition in the chamber of weapon and magazines during the long shooting, insecurity of ammunition during transportation, loss of its features during long storage. Construction, when the propellant charge is in the bullet, that was developed in the USA for the weapon Volkanik 1860, Gyroyjet 1965-their disadvantages are the low power of the ammunition which is from 30 to 250 J, and the lack of precision of the weapon, large dispersion, low performance reliability, high cost of manufacturing.
From the prior art, caseless ammunition for firearms is known (Patent RU No. 2153145, IPC F42B 5/18, publ. Jul. 20, 2000 Bul. No. 20) which comprises a body, a core, a flammable material, where the core has contact surface with the flammable material, and has shape of cone or pyramid with an angle of 50-170° that directed to the axis of ammunition with its top to the rear part and the body in the rear part of the ammunition, which is perpendicular to the axis of the ammunition, has a turbine with 2-8 guiding elements, that is covered outside by a layer of tele flammable material, wherein its thickness 0.2-3 mm, herewith a turbine is made of a high-temperature material; it has a thickness of 1.5-4 mm and with the body and core reaches object of distinction.
The disadvantages of this solution are:
substantial body drag that occurs during the bullet flight, because of the conical shape of the body;
dining the combustion of the propellant turbine will be pulled out by high gas pressure to 300 kg/cm2 due to press fit holder and as a result it will remain in the chamber of the weapon that will not allow to send next ammunition;
absence of the primer of the igniter in ammunition and military weapons dependence on electric energy source reduces the reliability of the weapon, especially in case of bad weather conditions (rain, fog, snow).
Known artillery round (Patent RU No. 2135938, IPC F42B 5/18, publ. Aug. 27, 1999) comprises warhead with driving band filled with propellant charge, combustion chamber with a receiver separated by a horizontal perforated diaphragm with a membrane, gasket and a primer. The combustion chamber is made in the form of a bush permanently joined to the warhead body where gasket, made as plate spring, is positioned, horizontal perforated diaphragm is located at the bush end face above the receiver and the propellant charge is located between gasket and horizontal perforated diaphragm.
The disadvantage of this solution is that the artillery ammunition can be used only for grenade launchers of 20 mm and higher, using high pressure in the combustion chamber and low pressure in the receiver together with the volume of the grenade launcher in the breech assembly, for a grenade volume—creating a chamber of low pressure, and ammunitions is not acceptable for hand small arms.
In addition, manufacture of artillery ammunitions requires a high manufacturing complexity and precision of the components, that increases the cost and decreases the reliability of the construction.
Known cartridge (Patent RU No. 2113686, IPC F42B 5/18, publ. Jun. 20, 1998) comprises a bullet, a propellant charge of a flammable material and a primer-igniter in which the bullet is made in the form of a hollow cylinder, provided with a membrane-wad, which is connected with the primer-igniter by a rod, passing along the bullet axis, and the propellant charge is positioned in the bullet cavity behind the membrane.
The disadvantages of this solution are:
substantial body drag that occurs during the bullet flight due to projecting inner rear part of driving band; as a rim for holding the high forces, which arise from the membrane, on which high gas pressure influences, during the combustion of the propellant, should, at least, has a height equal two-three wall thicknesses of hollow thin wailed cylinder, that forms body drag in end surface of the rim and vortex flow occurs the rim, as a result bullet can start. tumbling;
during motion of the stabilizer and a membrane, that has a disc shape and which is connected by rod into the rear part of bullet, due to incoming air flow, it is necessary to manufacture membrane disc is equal to three or four thicknesses of the wall of the hollow thin-walled cylinder, otherwise during the combustion of the propellant membrane disc can deform and wedge in hole, formed by the rim, due to the high gases pressure, that will result in destabilization of a bullet flight. Meanwhile the disk of membrane, which is equal to three or four thicknesses of the wall of the hollow thin walled cylinder, with rod will have a weight comparable to the weight of bullet and dining moving to the rear part they will rapidly change gravity center of the system ‘bullet-membrane’, which can also lead to destabilization of the bullet flight;
protruding primer-igniter, which is put on the rod and located in the rear part of the ammunition, bulges out, as a result it is unsafe during the transportation and lysing of such ammunitions, and non-authorized accumulation and explosion of ammunition can occur;
manufacture of these ammunitions requires high complexity and precision of manufacture of components (hollow thin-walled cylinder with an internal projection, the disk, connected by the rod, primer-igniter, flat stabilizer, a film of binding glue-material) which increases the cost and decreases the reliability of the construction.
This solution is the first prototype of the proposed technical solution.
From the prior art, mechanism for extraction of ammunitions and/or cartridge cases in a weapon with convertible barrel is known (Patent U.S. Pat. No. 6,839,997 B2, the IPC F41A15/06, F41A3/00, publ. May 05, 1992). Device for removal of cartridges and/or cartridge casings in a drop-barrel weapon, with at least one cartridge ejector axially displaceable in a barrel part for removal of unfired cartridges and an ejector mechanism acting on the cartridge ejector for ejection of spent cartridge casings, comprising the ejector mechanism has a locking pin, displaceable in the cartridge ejector, for releasable locking of the cartridge ejector in the barrel part, and a guide pm arranged in the cartridge ejector that engages on the cartridge ejector via a compression spring arranged in the interior of the cartridge ejector and can be displaced by a tension slide arranged on the barrel part, the locking pin being displaceable via an ejector firing pin operated by a striking pin piece into an advanced position, in which the cartridge ejector is locked relative to the barrel part via a locking mechanism, and the locking pin having a front end pin, via which, during full pivoting of the barrel part, the locking pin is pushed back by the guide pin into its rear position, in which locking of the cartridge ejector is released relative to the barrel part by the locking mechanism.
The disadvantage of this solution is the presence of cylindrical components, that slides in the tube of the barrel, working in tight conditions, and as a result dust pollution or contamination of the mechanism leads to unavoidable wedging of the mechanism and impossibility to extract the case. Also, this solution does not have a method of automatic removal of the case from the gun barrel, what makes the mechanism inapplicable to the weapon with automatic or semi-automatic reloading.
Known the extractor unit with one part (US20050115127 A1, F41A15/14, publ. Jun. 2, 2005) which includes an elongate extractor body configured to be disposed in the opening of the slide such that the slide encloses the extractor body. The elongate extractor body includes a first end and a second end. The second end of the extractor body is resiliently biased in a direction toward a round of ammunition and includes a portion configured to engage a rebate on a round of ammunition. The disadvantage of this solution is the high probability of wedging or disruption to ammunition feed during shooting from the weapon, as well as a bore in the bottom of the case is required for this type of extractor What increases the cost of the ammunition.
known extraction mechanism for firearm (Patent U.S. Pat. No. 7,380,362 B2, MIIK F41A 15/00, F41A 15/10, publ. Jun. 3, 2008) which comprising an extractor arm pivotally mounted within a pocket in a firearm slide. The extractor arm includes a body portion and a hook portion, the body portion being disposed within the pocket and the hook portion extending out of the pocket from an opening proximate to the breech face. The disadvantage of this solution is the technologically complex components of the mechanism, which operates in tight space, sprigs, also the mechanism is not protected from contamination by the external environment, that leads to dust pollution and contamination of the mechanism components. All the above-mentioned factors result in the wedging of the mechanism.
When all kinds of small arms used during long-term firing it is desirable to delay the moment of self-ignition of ammunition in heated weapon. During transportation of bulk ammunition, especially on rough terrain, due to shattering picket bullet of ammunition may fire primer-igniter which is close to ammunition, and therefore it is required to make acute end of bullet with platform, and prima-igniter—with increased rigidity. The relatively blunt end of the picket bullet decreases the range ability and bullet penetrating power, so it is desirable to make a bullet with an point end, and a primer—with less rigidity.
During shooting from weapon in closed spaces and within flying vehicles there is a danger that different devices are hit and wedged by cases, ricochet of cases from helicopter rotors may injure soldier. Due to the ricochet of the case soldier can get a burn, if there are cases under the legs, they can cause loss of balance and fall. Besides, the case has ⅔ of the weight of the ammunition, and therefore it increases the weight of the carriable amount of ammunition, and there are additional mechanisms in the operation of the weapon, slots and windows for extraction of the case required and that drastically decreases the reliability of the weapon. It is desirable to take case away and simplified the extraction.
During usage of caseless ammunition with U-shaped chamber it is desirable to enhance power of ammunition and so doing to reduce the weight without changing its dimensions. When all kinds of small arms with open chamber are used, it is desirable to have extraction only in manual reloading, it is desirable to eliminate extraction during.
During shooting from the weapon additional mechanisms, slots and windows for extraction of case are required what drastically decreases the reliability of the weapon. It is desirable to simplify extraction for weapon with open chamber.
The aim of the first proposed invention is to delay the moment of self-ignition of ammunition in heated weapon, to enhance the power of the caseless ammunition and to reduce its weight without changing its dimensions, to protect the primer from accumulation by the front point end of the ammunition, to reduce the losses of the shell velocity, to increase the penetrating power.
The aim of the second proposed invention is to simplify extraction of the proposed ammunition. This objective is achieved in that extraction is simplified by means of expanding ring or magnetic extraction washer-marker in ammunition, since these parts participate in extraction on a one-off basis during shooting and they are simple.
Another aim of mentioned invention is to provide reliability of ammunition extraction This objective is achieved in that the extraction of the ammunition is actuated only in manual reloading, and during the shooting the extraction mechanisms are not actuated.

in the proposed caseless ammunition the igniting blocks are made completely combustible, for example, they are made of nitrocellulose-bases plastic. As a result weight of ammunition is reduced without changing its overall dimensions, and their power increases;
there is a gap between the primer and the anvil of the ignition unit of the caseless ammunition and the front acute end of the ammunition, and the front acute end cannot break the primer. The acute end of the ammunition makes it possible to reduce the air resistance on the whole flight trajectory, thereby it allows to reduce the losses of the shell velocity. Also acute end of ammunition increases penetrating power in soft jackets thanks to extension of cells of cloth, and in solid armored jackets thanks to concentration of stresses on considerably smaller area in front acute end;
the propellant is located inside the ammunition, thanks to this and the structural features of the weapon there is provided a new method of shooting. This makes it possible to develop the necessary energy for particular types of weapons. It also allows to have different kinds of weapons for one type of ammunition and one structure;
at the joint of the conical part and the cylindrical part with the smaller diameter on the front end of the firing pin, the inclined shelf is formed, which opens the expanding ring for mechanical extraction and the firing pin with the igniting block drops out of gear and a conical bugling on the bolt gets a gap with rear end of proposed ammunition;
conical section is formed on the front end of the firing pin, during magnetic extraction that conical section is beyond the magnetic extraction washer-marker of the igniter block, wherein the magnetized magnetic extraction washer-marker torns off from the firing pin and the conical bushing on the bolt gets a gap of certain thickness with the rear end of the ammunition. The thickness of the gap does not allow the rear end of the ammunition to engage the conical hushing during ejection beyond the weapon, what provides reliability of the loading cycle, reloading cycle.

In order to make a shot with the help of the claimed caseless ammunition, it is necessary to have a caseless weapon, which mast have at least such mechanisms as: rifled barrel with cartridge chamber, barrel box, bolt with obturator, firing mechanism with striker, hammer in cocked position, firing spring, trigger, spring-loaded sear.
Shot is made with the help of claimed caseless ammunition in such way: ammunition is inserted into cartridge chamber of caseless weapon and is locked by bolt with obturator, where the problem of gas obturation in the bolt is solved. When the trigger is pressed, the spring-loaded sear comes out of engagement with the cocked position of the hammer and the hammer vigorously rotates under the action of the firing spring and strikes the striker. Striker fires primer of igniter block in caseles ammunition by its pan, propellant ignites, gases of high temperature and pressure are formed during the ignition of propellant and igniter block, they force shell to fly out of the barrel, rifling, getting axial rotation of the shell which is needed for stabilization of shell flight. There is combustible washer-marker in front of the primer of igniter block and when the washer is being burnt, the released gases pushes the standard primer of igniter block out after the shell. Depending on the purpose, changing the shell, it is possible to achieve a wide variety of tasks in shooting; claimed for invention ammunition can be armor-piercing, tracing, training, etc. If the igniter block is non-combustible, a mechanism of the ejecting of the igniter block is necessary in the weapon.
