Air Ukraine
Air Ukraine ( uk, Авіалінії України ''Avialiniyi Ukrayiny'') was a state-owned airline from Ukraine, serving as flag carrier of the country from 1992 to 2002. Headquartered in Kyiv, Air Ukraine operated scheduled passenger and cargo flights mostly on domestic routes or within the Commonwealth of Independent States, but also to global destinations. History The Dissolution of the Soviet Union during 1990 and 1991 lead to the split-up of former Soviet carrier Aeroflot in 1992, with Air Ukraine being founded out of the Aeroflot's Kyiv directorate. Soon, other Ukrainian divisions were merged into it to create a national airline. In December 2002, Air Ukraine was declared to be bankrupt. Attempts to relaunch the company by merging it with Aerosvit Airlines or Ukraine International Airlines failed, and the airline license was finally withdrawn on 23 July 2004. Fleet Over the years, Air Ukraine operated the following aircraft types: Incidents *On 5 Septem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rack Unit
A rack unit (abbreviated U or RU) is a unit of measure defined as . It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high. Definition The rack unit size is based on a standard rack specification as defined in EIA-310. The Eurocard specifies a standard rack unit as the unit of height; it also defines a similar unit, horizontal pitch (HP), used to measure the width of rack-mounted equipment. The standard was adopted worldwide as ''IEC 60297 Mechanical structures for electronic equipment – Dimensions of mechanical structures of the series'', and defines the sizes for rack, subrack (a shelf-like chassis in which cards can be inserted), and the pitch of printed circuit boards/ ...

Rack Mount
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or "ears" that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, 45U racks are also common. The term ''relay rack'' appeared first in the world of telephony. By 1911, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Politechnika Warszawska PW-6
The Politechnika Warszawska PW-6U is a Polish two-seat training sailplane designed at the Warsaw University of Technology for basic flight instruction and transition training to the PW-5 single-seater. It was manufactured at PZL Świdnik from 2000 and at ZS Jezow from 2007. Development The PW-6 was designed to be an ab initio trainer with the capability of providing cross-country training as well. It has handling and performance characteristics similar to the Politechnika Warszawska PW-5. In this way, it was envisaged that the transition to solo flying in the single-seater could be made sooner. The prototype of the PW-6, built at the Politechnika Warszawska, PZL Świdnik and DWLKK, made its maiden flight from Bemowo Airfield, Warsaw, in July 1998. Type certification was granted in September 2000, after Jerzy Kedzierski and Maciej Lasek completed the test flights. Serial production started at PZL Swidnik soon afterwards, with first deliveries to Egypt, New Zealand, Belgium, Canad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RG-6
RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, ''RG-6'', is generic and is applied to a wide variety of cable designs, which differ from one another in shielding characteristics, center conductor composition, dielectric type and jacket type. ''RG'' was originally a unit indicator 'Mike Meyers' CompTIA Network+ Certification Passport', by Glen E. Clark, edited by Christopher A. Crayton, McGraw-Hill, 3rd Edition, 2009, page 32. "Specific coax types were developed for the Ethernet standard, but a number of radio cables have very similar characteristics, and these so-called radio-grade (RG) cables also became associated with Ethernet." for bulk radio frequency (RF) cable in the U.S. military's Joint Electronics Type Designation System. The suffix ''/U'' means ''for general utility use''. The number was assigned sequentially. The ''RG'' unit ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenit (satellite)
Zenit (russian: link=no, Зени́т, , Zenith) was a series of military photoreconnaissance satellites launched by the Soviet Union between 1961 and 1994. To conceal their nature, all flights were given the public Kosmos designation. Description The basic design of the Zenit satellites was similar to the Vostok manned spacecraft, sharing the return and service modules. It consisted of a spherical re-entry capsule in diameter with a mass of around . This capsule contained the camera system, its film, recovery beacons, parachutes and a destruct charge. In orbit, this was attached to a service module that contained batteries, electronic equipment, an orientation system and a liquid-fuelled rocket engine that would slow the Zenit for re-entry, before the service module detached. The total length in orbit was around and the total mass was between . Unlike the American CORONA spacecraft, the return capsule carried both the film and the cameras and kept them in a temperature- ...

Xian H-6
The Xian H-6 () is a twin-engine jet bomber of the Chinese People's Liberation Army Air Force (PLAAF). The H-6 is a license-built version of the Soviet Tupolev Tu-16 and remains the primary bomber aircraft of the People's Republic of China. Delivery of the Tu-16 to China began in 1958, and a license production agreement with the Soviets was signed in the late 1950s. By November 2020, the PLAAF had as many as 231. The latest variant of the H-6 is the H-6N, a heavily redesigned version capable of aerial refueling and carrying air-launched cruise missiles. According to the United States Department of Defense, this will give the PLAAF a long-range standoff offensive air capability with precision-guided munitions. History Having entered service with the Soviet Union in April 1952, the Tupolev Tu-16 was one the Soviets' earliest effective jet bombers with over 1,500 produced through 1962. Early in 1956, the Soviet Union agreed to license production of the Tu-16 to the People's Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
