Beriev A-60
The Beriev A-60 is a Soviet/Russian airborne laser laboratory aircraft based on the Ilyushin Il-76MD transport. In the 1970s a special aviation complex was established by the Soviets at Taganrog machine-building factory to develop airborne laser technology for the Soviet military. In 1977 Beriev OKB started the design of a flying laboratory designated '1А'. The purpose was to solve the complex scientific and engineering problems regarding the creation of an airborne laser and also to facilitate research on the distribution of beams in the top layers of an atmosphere. Work on this topic occurred with wide cooperation between the enterprises and the scientific organizations of the USSR, but the basic partner OKB was TsKB Almaz headed by B.V. Bunkin. Design and development The Il-76MD was selected as the base aircraft for the flying laboratory. To accommodate the laser many changes were made to the basic IL-76 design, which drastically changed the appearance of the plane. * ...

Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, World War 1, Supermarine Nighthawk, an anti-Zeppelin night fighter.Andrews and Morgan 1987, p. 21.

T-tail Aircraft
A T-tail is an empennage wikt:configuration, configuration in which the tailplane is mounted to the top of the vertical stabilizer, fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a Wing_configuration#Number_and_position_of_main_planes, high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the British Aerospace ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

Science And Technology In The Soviet Union
Science and technology in the Soviet Union served as an important part of national politics, practices, and identity. From the time of Lenin until the dissolution of the USSR in the early 1990s, both science and technology were intimately linked to the ideology and practical functioning of the Soviet state, and were pursued along paths both similar and distinct from models in other countries. Many great scientists who worked in Imperial Russia, such as Konstantin Tsiolkovsky, continued work in the USSR and gave birth to Soviet science. The Soviet government made the development and advancement of science a national priority, emphasizing science at all levels of education and showering top scientists with honours. Very large numbers of engineers graduated every year. Soviet scientists won acclaim in several fields, marked by a highly developed pure science and innovation at the theoretical level, though interpretation and application fell short. They were at the cutting edge of sc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Military Lasers
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Boeing YAL-1
The Boeing YAL-1 Airborne Laser Testbed (formerly Airborne Laser) weapons system was a megawatt-class chemical oxygen iodine laser (COIL) mounted inside a modified military Boeing 747-400F. It was primarily designed as a missile defense system to destroy tactical ballistic missiles (TBMs) while in boost phase. The aircraft was designated YAL-1A in 2004 by the U.S. Department of Defense. The YAL-1 with a low-power laser was test-fired in flight at an airborne target in 2007. A high-energy laser was used to intercept a test target in January 2010, and the following month, successfully destroyed two test missiles. Funding for the program was cut in 2010 and the program was canceled in December 2011. It made its final flight on February 14, 2012, to Davis–Monthan Air Force Base in Tucson, Arizona, to be kept in storage at the "Boneyard" by the 309th Aerospace Maintenance and Regeneration Group. It was ultimately scrapped in September 2014 after all usable parts were removed. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
