Tupolev Tu-123
The Tupolev Tu-123 Yastreb (Hawk, russian: Ястреб) was one of the earliest Soviet reconnaissance drones that began development in 1960. Sometimes referred to as the "DBR-1", it was introduced into active service in 1964. Design The Tu-123 was a long-range, high-altitude supersonic strategic unmanned reconnaissance aircraft, in a form reminiscent of a big dart, conceptually somewhat similar to the United States' D-21. It carried both film cameras and SIGINT payloads. The Tu-123 was ground-launched with JATO boosting and powered by a KR-15 afterburning turbojet in flight. The KR-15 was a lower-cost, short-life, expendable version of the R-15 engine used on the twin-engine, Mach 3-class Mikoyan-Gurevich MiG-25 Foxbat interceptor. The Tu-123 itself was expendable, parachuting its payload to the ground for recovery. History Development The Tu-123 was a development of the proposed Tupolev Tu-121 supersonic nuclear-armed cruise missile program. After the cancellation of tha ...

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.

Unmanned Aerial Vehicles Of The Soviet Union
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own. Types There are different types of uncrewed vehicles: * Remote control vehicle (RC), such as radio-controlled cars or radio-controlled aircraft * Unmanned ground vehicle (UGV), such as the autonomous cars, or unmanned combat vehicles (UCGV) * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium-altitude long-endurance unmanned aerial vehicle (MALE) ** Miniature UAV (SUAV) ** Delivery drone ** Micro air vehicle (MAV) ** Target drone * Autonomous spaceport drone ship * Uncrewed surface vehicle (USV) ...

1960s Soviet Military Reconnaissance Aircraft
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus attempts to assassinate Clodius Albinus but fails, causing Albinus to retaliate militarily. * Emperor Septimius Severus captures and sacks Byzantium; the city is rebuilt and regains its previous prosperity. * In order to assure the support of the Roman legion in Germany on his march to Rome, Clodius Albinus is declared Augustus by his army while crossing Gaul. * Hadrian's wall in Britain is partially destroyed.

Tumansky KR-15
The Tumansky R-15 is an axial flow, single shaft turbojet with an afterburner. Its best known use is on the Mikoyan-Gurevich MiG-25. Design and development The R-15-300 was designed at the OKB-300 design bureau led by Sergei Tumansky in the late 1950s. The engine was originally intended for the Tupolev Tu-121 high-altitude high-speed cruise missile. Due to a lack of Soviet resources and funding the engine casing was mainly steel, and in areas exposed to high temperatures, 30 micrometre silver-plated steel. At the time, the USSR did not have the resources to exploit metals such as titanium or other alloys which could have reduced the weight of the engine. The Tu-121 was later canceled, but its basic design was used in the Tupolev Tu-123 reconnaissance drone. Performance The maximum thrust was 7,500 kilograms force (73.5 kN, 16,500 lbf) dry and 11,200 kilograms force (110 kN, 24,700 lbf) with afterburner. This thrust enabled the Mikoyan-Gurevich MiG-25, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MiG-25
The Mikoyan-Gurevich MiG-25 (russian: Микоян и Гуревич МиГ-25; NATO reporting name: Foxbat) is a supersonic interceptor and reconnaissance aircraft that is among the fastest military aircraft to enter service. Designed by the Soviet Union's Mikoyan-Gurevich bureau, it is an aircraft built primarily using stainless steel. It was to be the last plane designed by Mikhail Gurevich, before his retirement. The first prototype flew in 1964 and the aircraft entered service in 1970. It has an operational top speed of Mach 2.83. Although its thrust was sufficient to reach Mach 3.2+, its speed was limited to prevent engines from overheating at higher air speeds and possibly damaging them beyond repair."Intelligence: Big-Mouth Belenko" ''Time'', 11 Oct ...

Soviet Air Force
The Soviet Air Forces ( rus, Военно-воздушные силы, r=Voyenno-vozdushnyye sily, VVS; literally "Military Air Forces") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Soviet republics, including the new Russian Air Force. "March of the Pilots" was its song. Origins The ''All-Russia Collegium for Direction of the Air Forces of the Old Army'' (translation is uncertain) was formed on 20 December 1917. This was a Bolshevik aerial headquarters initially led by Konstantin Akashev. Along with a general postwar military reorganisation, the collegium was reconstituted as the "Workers' ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part ...

Cruise Missile
A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non- ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film '' The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the American aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and a barometric altitude control. Inspired by the experiments, the United States Army developed a similar flying bomb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
