The phenomenon of the shot clearly traced the relationship and interaction of some elements, and other factors.For example, the velocity of the projectile in the barrel depending on the pressure, but the pressure is dependent on the intensity of combustion of gunpowder and the volume zasnaryadnogo space, which in turn depends on the velocity of the projectile. In the study of the shot, all these factors are considered in relationship.In the phenomenon of shots distinguish the following periods:preliminary period – the composition of the capsule from the explosion before driving the upper Read more [...]
It's about the primer such as "Zhevelo", for which the ignition of gunpowder is a condition necessary but not sufficient. Photo by Mikhail Semin As is known, the combustion rate of smokeless powders depends on the pressure of the surrounding gas, where combustion takes place. At atmospheric pressure, the powder safely lit, but in a closed space, when the pressure begins to increase, the rate of combustion of gunpowder is increased, which causes further increase in pressure, and so forth. There is an avalanche process of burning gunpowder.It is obvious that the total propellant Read more [...]
The ice on the reservoir in a protracted thaw has melted and held until recently. Now, after the severe frosts, ice even more stronger and almost to the very lamb makes a sharp bite my ice screws. Snowfalls – also did a good job! Now on the ice large snow drifts, insurmountable for vehicles. Walking on them is difficult. It holds a strong infusion, the legs fail treacherous ankle-deep in snow. It's nice to remember long-forgotten experience! It is not often indulges Volgograd winter snow!And the day turned out to be – how to order! Barely perceptible breeze, a cloudless Read more [...]
The other day, I conducted an experiment whose result for me was almost predictable. It was necessary only to find out some numbers to work with. Photo Shutterstock.com The essence of the experiment is as follows. The sleeve charged only one capsule «Zhevelo»I inserted wads of nine different species, but instead shot – rod weighing 0.6 kg. When fired, the measured altitude. It was found that the harder «cushioning» part of the wad, the higher takeoff shaft.The highest result of 3.0 m was obtained wad without any shock absorber. Therefore, the power Read more [...]
Boris Laputko incorrectness of reasoning is that the general principles of inertia, to which it refers, are dynamic, but the pressure forcing (that is, which is defined by the author himself) is in its physical sense, but starting at the beginning of a dynamic process.What is happening in the cartridge from the flash before opening the capsule and the sleeve is essentially static.Indeed there is the inertia of rest, but the rest (that is, until the body is not free and is not a movement) no manifestations of inertia, we do not see. In any case, until the twist and the strength of friction hold Read more [...]
It would seem that this question has long been irrelevant, because many have long believed that a person of sound mind liner this does not apply.

The classical science of internal ballistics barrel systems are rarely used the concept of forcing period, analyzes the impact of discrete values of the pressure boosting. For artillery classical systems is the pressure at which the leading band of the projectile fully enter the rifling of the barrel. The rifled barrel firearms boost pressure is the pressure at the time when the bullet will be fully rifling of the barrel.Thus, in order not to complicate the analysis, it is assumed – shell and bullet enters the rifling of the barrel and instantly boost pressure equal to the pressure Read more [...]
During the weekend of May on our website intertwined two themes: the first - about the dangers of cartridges such as "Magnum" in IL-27 (N. Rogachev), the second - a recipe goose cartridge with the sample powder "Falcon" (unless it is a mistake ) equal to 2.8 g and 40 g starch fraction (VF Gomov).Photo by Anton Zhuravkova I decided to bring this discussion to a common denominator. Firstly, I fully share the opinion of hunters who think that sleep in the cartridge is significantly inflated hitch «Falcon». «to stronger vdarit», Futile and ultimately unsafe.Very Read more [...]
Photo by Sergey Fokin Once entered into a polemic between A. and B. Laputko Yarkov little over a year ago and expressed his views on the subject of friction and wedging more not to engage in it. Excessive prolonged dispute grew out of the way the search for truth and the exchange of experiences in a squabble with mutual attacks, which dominates the desire to satisfy their own ambitions, savoring personal dislike. In my view, such a tone of the discussion is not worth doing domain readers. And so hats off to A. Yarkov, who apparently had himself put it point its publication.I also Read more [...]

The controversy between Boris and Alexander Yarkov Laputko seem erupted in earnest. It is interesting to observe from all the vicissitudes of this struggle.

Catching sighting hunting rifles, are often faced with hard questions. Sometimes you can not even get a good fight. The gun like a charm - nothing helps. You change the thickness of cardboard pads, their number, type of wads that make up the combined wad — felted plus hardboard, — change the ratio of the mass of powder and fractions with eksperimentiruesh various containers, change «Zhevelo-H» on «Zhevelo-M» and on the contrary, you try different liners, different ways of rolling, to compress the powder Other efforts — Read more [...]

Thanks to our extensive anticyclone, in the center of Russia still extremely high atmospheric pressure.
Today also marks another record. By 11 o'clock the atmospheric pressure in the city (according to the reference weather station ENEA) increased to 1027.4 hPa (770.61 millimeters of mercury). The maximum amount by which the pressure was increased on January 21 was 1027.3 hPa (770.54 mm Hg) and was observed in 1973
Set fourth in the current January record of atmospheric pressure.
Monthly record is in 1972, when under the pressure of anticyclonic weather in Moscow rose to 780.74 millimeters of Read more [...]

Long periods rainless set at 80% of the cases in the fields of high pressure, i.e. in the central part of anticyclones, ridges, or "fuzzy" fields of high pressure. Drought, 67% of the intensive development of the meridional circulation forms. On the Status of tall ridges and troughs relative to Western Siberia are three types of processes that lead to long rainless periods, drought (see Fig. 5.9) .

Test POWDER "FALCON".• In the vastness of the Russian Federation in a number of circumstances more versprochenen remains gunpowder "Falcon". But the tips of plant equipment with this powder remain very poor. The plant still gives advice only on antiquated equipment with the introduction of cardboard, fiberboard (not even felt the wads and rolling the sleeves. Well as in the 19th century.

Untried little idea - create remedies for animals.
The animal does not die, but the scent and the desire to get closer lost.
If anyone tries - unsubscribe. I'm sorry to spoil the fire extinguisher.
So - take a powder extinguisher (plastic only)
