MP-448 Skyph
The MP-448 ''Skyph'' (MP-448 '' Скиф'') is a Russian pistol. History The MP-448 was developed during the late 1990s by engineer-constructor and weapon designer Dmitry Bogdanov. It was initially offered by Izhevsk Mechanical Plant (IzhMech) for export sales and for private security companies as an enhanced version of the famous Makarov PM pistol (which is also manufactured by IzhMech). In November 2000 one MP-448 pistol and one MP-448C pistol were presented at "INTERPOLITEX-2000" Arms exhibition in Moscow, they were offered for export.Юрий Амелин.

Semi-automatic Pistol
A semi-automatic pistol (also called a self-loading pistol, autopistol, or autoloading pistol) is a repeating firearm, repeating handgun that automatically ejects and loads cartridge (firearms), cartridges in its chamber (firearms), chamber after every shot fired, but only one round of ammunition is fired each time the Trigger (firearms), trigger is pulled. The pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset manually, unlike the self-cycled firing mechanism in machine pistol, fully automatic pistols. A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt (firearm), bolt, which is usually housed inside the pistol slide, slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer (firearms), hammer/striker is cocked by the slide/bolt movement, and a ...

Pounds Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mikhail Kalashnikov
Mikhail Timofeyevich Kalashnikov (10November 191923December 2013) was a Soviet and Russian lieutenant general, inventor, Military engineering, military engineer, writer, and small arms designer. He is most famous for developing the AK-47 assault rifle and its improvements, the AKM and AK-74, as well as the RPK light machine gun and PK machine gun. Kalashnikov was, according to himself, a self-taught tinkerer who combined innate mechanical skills with the study of weaponry to design arms that achieved battlefield ubiquity. Even though Kalashnikov felt sorrow at the weapons' uncontrolled distribution, he took pride in his inventions and in their reputation for reliability, emphasizing that his rifle is "a weapon of defense" and "not a weapon for offense". Early life Kalashnikov was born in the village of Kurya, Kuryinsky District, Altai Krai, Kurya, in present-day Altai Krai, Russia, as the seventeenth child of the 19 children of Aleksandra Frolovna Kalashnikova (née Kaverina) ...

Private Security Company
A private security company is a business entity which provides armed or unarmed security services and expertise to clients in the private or public sectors. Overview Private security companies are defined by the U.S. Bureau of Labor Statistics as companies primarily engaged in providing guard and patrol services, such as bodyguard, guard dog, parking security and security guard services. Many of them will even provide advanced special operations services if the client demands it. Examples of services provided by these companies include the prevention of unauthorized activity or entry, traffic regulation, access control, and fire and theft prevention and detection. These services can be broadly described as the protection of personnel and/or assets. Other security services such as roving patrol, bodyguard, and guard dog services are also included, but are a very small portion of the industry. During the COVID-19 pandemic, some security companies engaged in vaccine supply chain s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ergonomics
Ergonomics, also known as human factors or human factors engineering (HFE), is the application of Psychology, psychological and Physiology, physiological principles to the engineering and design of products, processes, and systems. Primary goals of human factors engineering are to reduce human error, increase productivity and system availability, and enhance safety, health and comfort with a specific focus on the interaction between the human and equipment. The field is a combination of numerous disciplines, such as psychology, sociology, engineering, biomechanics, industrial design, physiology, anthropometry, interaction design, visual design, user experience, and user interface design. Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to previously stated goals. In studying and sharing learning on the design of equipment, devices, and processes that fit the human body and its Cog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blowback Operation
Blowback is a system of operation for Semi-automatic firearm, self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt (firearms), bolt movement. In most actions that use blowback operation, the Breech-loading weapon, breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of Gas-operated reloading, gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loadin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
