Silent cleaning cartridge for small arms

FIELD: weapons. SUBSTANCE: invention relates to weapons, namely to small arms ammunition. A cleaning cartridge for small arms contains a bottle-type cartridge case with an igniter primer, a piston with the possibility of locking powder gases in the cartridge case, and a mechanical pusher of a thrown cleaning caliber projectile. The thrown cleaning projectile is made as a coil due to at least two annular grooves spaced as far as possible along its length. The cavities of the grooves are blocked by the crimped muzzle of the sleeve. The front groove is filled with cleaning fluid and the rear groove is filled with lubricating fluid. Sections of the caliber cylindrical surface of the projectile, separated by grooves, are made with unequal surface roughness and, accordingly, unequal abrasive properties in relation to powder deposits in the bore. EFFECT: ensuring prompt cleaning and improving the quality of cleaning and finishing lubrication of the barrel bore at the same time with the noiselessness of the cartridge during its use. 1 cl, 3 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 768 580 C1 (51) МПК F42B 5/24 (2006.01) F42B 14/04 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F42B 5/24 (2022.02); F42B 14/04 (2022.02) (21)(22) Заявка: 2021120207, 08.07.2021 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Семенов Александр Георгиевич (RU) Дата регистрации: 24.03.2022 Приоритет(ы): (22) Дата подачи заявки: 08.07.2021 (45) Опубликовано: 24.03.2022 Бюл. № 9 2 7 6 8 5 8 0 R U (54) Бесшумный очищающий патрон для стрелкового оружия (57) Реферат: Изобретение относится к вооружению, а канавка заполнена чистящей жидкостью, а задняя именно к боеприпасам стрелкового оружия. канавка заполнена смазывающей жидкостью.

Method of solid-propellant charges armoring

FIELD: weapons and ammunition. SUBSTANCE: invention relates to production of armored solid propellant charges, which coating prevents reserved surfaces burning. Heat-resistant fuel charge armoring is performed in two stages. At first stage on fuel cartridge surface glue EL-20 is applied by brush based on epoxy resin of ED-20 grade and low-molecular polyamide L-20 as adhesive interlayer, on which from above glass fabric or coarse calico impregnated with glue EL-20 is applied in two layers.

Gas generant formulation with reducing inflator particulate

인플레이터용 가스발생제는 차량 사고 발생 시 탑승자 보호를 위한 에어백을 팽창시키는데 필요한 화약조성물이다. 차량 충돌로 센서에 의해 감지된 전기 신호는 인플레이터의 점화기, 점화약 및 가스발생제의 순서로 점화 및 연소가 이루어지게 한다. 가스발생제의 연소에 의해 발생한 가스와 고온의 용융화합물은 필터를 통해 냉각되고 여과되어 에어백을 팽창시킨다. 고온의 용융화합물이 필터에서 효과적으로 냉각되고 여과되기 위해서는 슬래그로 전환되어야 한다. 본 발명에서는 슬래그형성제로 제올라이트(Zeolite) [Na 4 Al 4 Si 4 O 25 H 18 ] 또는 돌로마이트(Dolomite)[CaMg(CO 3 ) 2 ]를 사용하여 고온의 용융 화합물을 슬래그로 전환시키고 인플레이터 전개 시 에어백 내부로 배출되는 연소 잔사물의 양을 USCAR-24 기준치인 1g 이하로 만족시킴으로써 에어백의 손상을 막고 탑승자를 효과적으로 보호할 수 있다. A gas generating agent for an inflator is a gunpowder composition necessary to inflate an air bag for occupant protection in the event of a vehicle accident. The electrical signals detected by the sensors in the event of a vehicle collision ignite and burn in the order of the igniter, the igniter and the gas generator of the inflator. The gas generated by the combustion of the gas generating agent and the hot molten compound are cooled through the filter and filtered to expand the air bag. The hot molten compound must be converted to slag to be effectively cooled and filtered in the filter. In the present invention, zeolite [Na 4 Al 4 Si 4 O 25 H 18 ] or dolomite [CaMg (CO 3 ) 2 ] is used as a slag forming agent to convert a hot molten compound into slag, By satisfying the USCAR-24 standard value of 1g or less, the amount of burned residue discharged into the airbag can be prevented from damaging the airbag and effectively protecting the occupant.
