SA-N-1
The S-125 ''Neva/Pechora'' (russian: С-125 "Нева"/"Печора", NATO reporting name SA-3 ''Goa'') is a Soviet surface-to-air missile system that was designed by Aleksei Isaev to complement the S-25 and S-75. It has a shorter effective range and lower engagement altitude than either of its predecessors and also flies slower, but due to its two-stage design it is more effective against more maneuverable targets. It is also able to engage lower flying targets than the previous systems, and being more modern it is much more resistant to ECM than the S-75. The 5V24 (V-600) missiles reach around Mach 3 to 3.5 in flight, both stages powered by solid fuel rocket motors. The S-125, like the S-75, uses radio command guidance. The naval version of this system has the NATO reporting name SA-N-1 Goa and original designation M-1 Volna (Russian Волна – ''wave''). Operational history Soviet Union The S-125 was first deployed between 1961 and 1964 around Moscow, augmenting the ...

NATO Reporting Name
NATO reporting names are code names for military equipment from Russia, China, and historically, the Eastern Bloc (Soviet Union and other nations of the Warsaw Pact). They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes. For example, the Russian bomber jet Tupolev Tu-160 is simply called "Blackjack". NATO maintains lists of the names. The assignment of the names for the Russian and Chinese aircraft was once managed by the five-nation Air Standardization Coordinating Committee (ASCC), but that is no longer the case. American variations The United States Department of Defense (DOD) expands on the NATO reporting names in some cases. NATO refers to surface-to-air missile systems mounted on ships or submarines with the same names as the corresponding land-based systems, but the US DoD assigns a different series of numbers with ...

Aleksei Isaev
Aleksei Mikhailovich Isaev (also Isayev; Russian: Алексе́й Миха́йлович Иса́ев; October 24, 1908, in Saint Petersburg – June 10, 1971, in Moscow) was a Russian rocket engineer. Aleksei Isaev began work under Leonid Dushkin during World War II, on an experimental rocket-powered interceptor plane, the BI-1. In 1944 he formed his own design bureau to engineer liquid-propellant engines. After abandoning the heavy, complex and undercooled German engine designs, Russia's principal engine designer Valentin Glushko turned to Isaev's innovations: thin-walled copper combustion chambers backed by steel support, anti-oscillation baffle to prevent chugging, and the flat injector plate with mixing-swirling injectors. The latter was an enormous simplification of the "plumbing nightmare" of the V-2 engine, because it avoided the need for separate fuel lines to each sprayer. Staged combustion (Замкнутая схема) was first proposed by Alexey Isaev in 194 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

National Air Force Of Angola
The National Air Force of Angola or FANA ( pt, Força Aérea Nacional de Angola) is the air branch of the Armed Forces of Angola. With an inventory of more than 300 aircraft, FANA is (on paper) one of the largest and strongest air forces of Africa. History Angola became independent from Portugal on 11 November 1975. However, the foundations for the establishment of the air force were laid before independence when members of the then Flying Club of Angola () were assembled at Luanda in October 1975. These people and aircraft left behind by the Portuguese Air Force formed the basis for the air transport branch of the force. The force was formally established on 21 January 1976 as the People's Air Force of Angola / Air and Antiaircraft Defense or FAPA/DAA (). Its first batch of Soviet MiG fighter aircraft was delivered in mid-December 1975. The FAPA/DAA fought several battles with South African Air Force aircraft in November 1981, October 1982, and twice in September 1987. Circ ...

Rocket Motor
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the ex ...

Solid Fuel
Solid fuel refers to various forms of solid material that can be burnt to release energy, providing heat and light through the process of combustion. Solid fuels can be contrasted with liquid fuels and gaseous fuels. Common examples of solid fuels include wood, charcoal, peat, coal, hexamine fuel tablets, dry dung, wood pellets, corn, wheat, rye, and other grains. Solid fuels are extensively used in rocketry as solid propellants. Solid fuels have been used throughout human history to create fire and solid fuel is still in widespread use throughout the world in the present day. Types of solid fuels Wood Wood fuel can refer to several fuels such as firewood, charcoal, ''wood chips'' sheets, pellets, and sawdust. The particular form used depends upon factors such as source, quantity, quality and application. In many areas, wood is the most easily available form of fuel, requiring no tools in the case of picking up dead wood, or few tools. Today, burning of wood is the largest use ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.
