Description

Oblast tehnike u koju spada pronalazakFIELD OF THE INVENTION

Pronalazak se odnosi na uredaj prilagodljiv svim projektnima i municijama, kao što su artiljerijski projektili, kod kojih se javlja aerodinamički otpor zadnjeg dela, i ima za zadatak da smanji taj otpor, kako bi se u znatnoj meri povecao domet oruda i preciznost gadanja (medunarodna patentna klasifikacija: F 42B 5/00, F 42B 13/267).The invention relates to a device adaptable to all projectiles and ammunition, such as artillery projectiles, in which aerodynamic rear resistance occurs, and is intended to reduce that resistance in order to substantially increase gun range and precision (international patent classification: F 42B 5/00, F 42B 13/267).

Uredaj prema pronalasku sadržan je u zasebnom pakovanju, odvojenom od municije koju oprema, snabdeven svim sistemima i sredstvima neophodnim za dejstvo. Neposredno pre ispaljivanj može se montirati ili ne, zavisno od udaljenosti cilja koji se gada, na koji način se rešava problem diferencijalnog dometa. Tako uredaj prema pronalasku predstavlja pravi kit koji se može u svakom momentu staviti na svaku municiju pripremljenu na vrlo jednostavan način za prijem uredaja.The apparatus according to the invention is contained in a separate package, separate from the ammunition provided by the equipment, provided with all systems and means necessary for the operation. Immediately before firing, it may or may not be mounted, depending on the distance of the target being targeted, which solves the differential range problem. Thus, the device according to the invention is a real kit that can be attached to any ammunition at any time prepared in a very easy way to receive the device.

Tehnički problemTechnical problem

Tehnički problem koji je rešen ovim pronalaskom sastojao se u torne da se ostvari uredaj sa smanjenje otpora municije koji se lako može staviti na postojeci projektil kako bi znatno povecao domet oruda, pri čemu se projektil može, ako se želi smanjenje dometa, ispaljivati i bez uredaja.The technical problem solved by the present invention consisted in towers to create an ammunition-reducing device that could easily be mounted on an existing missile to substantially increase the range of a tool, whereby the projectile could be fired without the device if desired. .

Stanje tehnikeThe state of the art

Da bi se povecao domet kod gadanja projektnima kao što su zrna izbacivana iz artiljerijskih oruda, mogu se koristiti dva načina:There are two ways to increase the reach of projectiles such as grains thrown from artillery shells:

- primena dodatnog potiska,- application of additional thrust,

- primena generatora gasova, poznatog kao base bleed.- the application of a gas generator, known as base bleed.

U slučaju dodatnog potiska, potisno punjenje je smešteno u komoru unutar projektila. Sagorevanjem u potisnoj komori izaziva se dodatno ubrzanje projektila na njegovoj putanji. Nedostatak ovoga uredaja leži u torne da ubrzanje na početku putanje osetno umanjuje preciznost gadanja. Ovome se pridodaje i znatno povečanje mase projektila, tako da dobitak na dometu nije u srazmeri sa dodatnom potrošnjom energije. Osim toga, kako se dužina projektila ne može neograničeno povecavati iz balističkih razloga i zbog problema pri skladištenju, neizbežno je da sedodavanje potisnog punjenja vrši na štetu korisne zapremine projektila.In the case of additional thrust, the thrust charge is housed in a chamber inside the missile. Combustion in the thrust chamber causes additional projectile acceleration in its trajectory. The disadvantage of this device lies in the towers that the acceleration at the beginning of the trajectory significantly reduces the precision of shooting. This is compounded by a significant increase in projectile mass, so the gain on range is out of proportion to the extra power consumption. In addition, since the length of the projectile cannot be increased indefinitely for ballistic reasons and due to storage problems, it is inevitable that sedentary charge loading does not adversely affect the useful capacity of the projectile.

3.3.

Drugi uredaj sastoji se od generatora gasova smeštenog u komori u osnovi projektila. Ovaj generator gasova stavlja se u pogon pomocu odgovarajučeg upaljača, na samom početku leta projektila. Gasovi proizvedeni delovanjem ovog generatora izlaze kroz otvor izveden na komori za sagorevanje u osnovi projektila. Izbacivanje vrelih gasova proizvedenih sagorevanjem ne izaziva nikakvo ubrzanje i ograničeno je na ispunjavanje depresione zone, aerodinamičkog porekla, koja se javlja na zadnjem delu projektila i koja stvara otpor koji u znatoj meri umanjuje domet. Buduci da je na ovaj način neutralisan otpor na zadnjem delu zrna, domet je znatno uvecan. Prednost ovog uredaja leži u torne što se uz pomoč znatno ekonomičnijeg načina izvodenja u odnosu na ranije poznate postiže odgovarajuee povečanje dometa (do 30%). Staviše, kako se povečanje dometa postiže samo ispunjavanjem aerodinamičke šupljine i bez ubrzanja, preciznost gadanja je znatno veča u odnosu na onu koja se postiže dodatnim potiskivanjem zrna.The second device consists of a gas generator housed in the chamber at the base of the projectile. This gas generator is powered by a suitable lighter at the start of the missile flight. The gases produced by the operation of this generator exit through an opening made on the combustion chamber at the base of the projectile. The ejection of hot gases produced by combustion does not cause any acceleration and is limited to the filling of the depression zone, aerodynamic origin, which occurs at the rear of the projectile and which creates resistance that greatly reduces the range. As the back grain resistance is neutralized in this way, the range is greatly increased. The advantage of this device lies in the towers, which with the help of a much more economical way of performing in comparison with the previously known, achieves a corresponding increase in range (up to 30%). Moreover, as the increase in range is achieved only by filling the aerodynamic cavity and without acceleration, the precision of aiming is much higher than that achieved by additional grain suppression.

Ovakav uredaj je opisan u francuskom patentu broj 2 328 93θ·This device is described in French Patent No. 2 328 93θ ·

Taj uredaj je sastavni deo projektila, tako da se ne može od njega odvojiti niti zasebno skladištiti, da bi se mogao, u trenutku gadanja, dodati na projektil. Osim toga, čak i kada hi se ovaj uredaj mogao odvojiti od projektila, projektil se ne bi mogao ispaliti jer njegov zadnji deo ne bi imao mehaničku otpornost dovoljnu za pritisak koji nastaje u cevi oruda iz kojeg se ispaljuje.This device is an integral part of the projectile, so it cannot be detached or stored separately so that it can be added to the projectile at the time of firing. In addition, even if this device could be detached from the projectile, the projectile could not be fired because its rear end would not have mechanical resistance sufficient for the pressure generated in the barrel of the gun from which it was fired.

Opis rešenja tehničkog problemaDescription of solution to a technical problem

Prema pronalasku, uredaj za smanjenje otpora munucije kao što su artiljerijski projektili, koji sadrži pirotehničku smesu kao što je propergol čije sagorevanje proizvodi gasove pod pritiskom najmanje dovoljnim da se popuni podpritisak stvoren na zadnjem kraju municije koji je uzrok njenom otporu, naznačen je time što se sastoji od kucišta u kojem se nalaze pirotehnička smeša i upaljač koji omogučava paljenje smeše, pri čemu je kučište hermetički zatvoreno i sadrži sredstva za učvrščivanje koja sadejstvuju sa odgovarajucim sredstvima za učvrščivanje predvidenim na zadnjem kraju municije, da bi se omogucilo postavljanje kucišta, uz zaptivanje, u svakom momentu a naročito na terenu, na zadnji deo municije, u cilju smanjenja njenog otpora i povečanja dometa.According to the invention, a device for reducing ammunition resistance such as artillery projectiles, containing a pyrotechnic mixture such as propergol whose combustion produces pressurized gases at least sufficient to fill the subpressure created at the rear end of the ammunition that causes its resistance, is characterized in that consists of a housing containing a pyrotechnic mixture and a lighter which enables the ignition of the mixture, the housing being hermetically sealed and containing fixing means which cooperate with the appropriate fixing means provided at the rear end of the ammunition, to enable the housing to be fitted with a seal, at all times and especially in the field, to the rear of the ammunition, in order to reduce its resistance and increase its range.

Cinjenica da je kučište uredaja hermetički zatvorenoThe fact that the housing of the device is hermetically sealed

omogučava njegovo uskladištenje u pakovanjima odvojenim od projektila, tako da uredjaj može pričvrstiti, u svakom trenutku, na zadnji deo klasičnog projektila naročito na samorn poligonu.allows it to be stored in projectiles separate from the projectile, so that the device can attach, at any time, to the back of a classic projectile, especially on a self-propelled polygon.

Tako je, u slučaju artiljerijskog zrna, moguče doneti na licu mesta odluku, da li je neophodno,.u zavisnosti, od željenog dometa, dodati uredjaj na zadnji deo projektila.Thus, in the case of artillery grain, it is possible to decide on the spot whether it is necessary, depending on the desired range, to add a device to the rear of the projectile.

Uredjaj prema pronalasku koji je prilagodljiv postoječim projektnima uz pomoč neznatne izmene na njihovom zadnjem delu, omogučava, dakle, povečanje njihovog dometa, dozvoljavajuči nesmetano ispitivanje projektila nezavisno od uredjaja kada ovo povečanje dometa nije ne ophodno.A device according to the invention that is adaptable to existing designs with a slight modification to their rear allows, therefore, an increase in their range, allowing smooth projectile testing independently of the device when this range increase is not necessary.

Tako, činjenica da se projektil može ispaliti bez uredjaja prema pronalasku, u slučaju hica normalnog dometa, omogučava znatne uštede. Pronalazak, prema torne, omogučava podešavanje dometa, ne samo pomoču jačine punjenja, nišanskog ugla, več i dodavanjem, u izvesnim slučajevima uredjaja prema pronalasku. Ove mogučnosti nisu postojale u slučaju francuskog patenta 2 528 953.Thus, the fact that a projectile can be fired without a device according to the invention, in the case of normal range shots, provides considerable savings. The invention, according to the towers, allows adjustment of the range, not only by the aid of the charging strength, the aiming angle, but also by the addition, in certain cases, of the devices according to the invention. These possibilities did not exist in the case of French patent 2 528 953.
