Czilim-class Hovercraft
The Czilim-class ACV (Project 20910) is a small patrol hovercraft operated by the Border Guard Service of Russia. Configuration The Czilim class is the first new class of military hovercraft developed for the Russian military since the fall of the Soviet Union. It is based on an Almaz design and was ordered from Jaroslawski Sudostroiteinyj Zawod in the late 1990s. It is roughly the same size as the British SR.N6 hovercraft. The Czilim class was designed for border patrol duties on the Amur River on the border with China, and is expected to be used entirely by Russian Border Guards. It is intended as a smaller replacement for the Soviet . The first craft was laid down on 24 February 1998 and entered service in early 2001. Three further craft were built at Yaroslavl between 1997 and 1999. Four were in service in 2004, though none are believed to be currently operational. The Czilim class is capable of carrying six Border Guards and their equipment. See also * List of ships o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Border Guard
The Border Service of the Federal Security Service of the Russian Federation (PS FSB Rossii) (russian: Пограничная служба Федеральной службы безопасности Российской Федерации (ПС ФСБ России)) is a branch of Federal Security Service of Russia tasked with patrol of the Russian border. The terms Border Service of Russia (russian: Пограничная служба России) and Border Force of Russia (russian: Пограничные войска России) are also common, while in English, the terms "Border Guards" and "Border Troops" are frequently used to designate this service. The Border service numbers around 170,000 active members, which includes the Russian maritime border guard units (i.e., the coast guard). History Tsarist and Imperial Russia One can trace the origin of the Russian border service to 1571 and the work of Prince Mikhail Vorotynsky (died 1573) and his Great Abatis Bord ...

Hovercraft
A hovercraft, also known as an air-cushion vehicle or ACV, is an amphibious Craft (vehicle), craft capable of travelling over land, water, mud, ice, and other surfaces. Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk- or oval-shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. The first practical design for hovercraft was derived from a British invention in the 1950s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications, as well as for sport or passenger service. Very large versions have been used to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutz AG
Deutz AG is a German internal combustion engine manufacturer, based in Porz, Cologne, Germany. History The company was founded by Nicolaus Otto, the inventor of the four-stroke internal combustion engine, and his partner Eugen Langen on 31 March 1864, as N. A. Otto & Cie, later renamed to Gasmotoren-Fabrik Deutz after moving operations in 1869 from Cologne to Deutz, located on the opposite side of the Rhine, also called "the wrong side" in Cologne. In the early years, Otto and Langen were interested only in producing stationary engines, not automobiles. Georgano, G.N. ''Cars: Early and Vintage, 1886-1930''. (London: Grange-Universal, 1985) The technical director, Gottlieb Daimler, was eager to produce automobiles. In the middle of the 1870s, it was suggested that he transfer to the company's St. Petersburg factory to reduce his influence. He resigned, taking Wilhelm Maybach with him. Deutz also produced agricultural machines such as combine harvesters and tractors, as we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable-pitch Propeller (aeronautics)
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed (RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is st ...

I Band (NATO)
The NATO I band is the obsolete designation given to the radio frequencies from 8 000 to 10 000 MHz (equivalent to wavelengths between 3.75 and 3 cm) during the Cold War period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA). However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electronic warfare Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults. The purpose of electronic warfare is to deny the opponen ... activities, or in military operations, this system is still in use. References Radio spectrum Microwave bands {{Wireless-stub ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40 Mm Grenade
40 mm grenade (also styled 40mm grenade) is a generic class-name for grenade launcher ammunition ( subsonic shells) in caliber. The generic name stems from the fact that several countries have developed or adopted grenade launchers in 40 mm caliber. This is a general collection of the world's many different "40 mm grenades". NATO NATO currently uses three standardized 40 mm grenade families: 40 mm low velocity (LV), 40 mm medium velocity (MV), and 40 mm high velocity (HV). Low- and medium-velocity cartridges are used for different hand-held grenade launchers, while the high-velocity cartridge is used for automatic grenade launchers. 40×46 mm LV (40 mm low velocity) ''40×46 mm LV'' (''low velocity'') is a NATO-standard high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, and Heckler & Koch AG36. The propellant has low pressure and gives the projectile an average velocity of depending on the ammuniti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
