Dornier 328Jet
The Fairchild-Dornier 328JET is a Regional jet, commuter airliner, based upon the turboprop-powered Dornier 328, developed by the German aircraft manufacturer Dornier Flugzeugwerke, Dornier Luftfahrt GmbH. It would be the last Dornier-designed aircraft to reach production before the company's collapse during the early 2000s. The 328JET was designed by Dornier in response to negative feedback from some customers on the marketability of turboprops against the more appealing turbofan engine. It was a relatively straightforward re-engining of the existing 328, being originally designated as the ''328-300'' prior to being rebranded as the ''328JET''. During 1996, early on in the programme, the financially distressed Dornier company was acquired by the United States, American aerospace firm Fairchild Aircraft; the resulting corporation, named Fairchild Aircraft, Fairchild Dornier, continued development of the 328JET. On 20 January 1998, the first 328JET prototype conducted its maiden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new type must be certified by a governing agency (such as the Federal Aviation Administration in the United States) before it can enter ...

Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

Derating
In electronics, derating is the operation of a device at less than its rated maximum capability to prolong its life. Typical examples include operations below the maximum power rating, current rating, or voltage rating. In electronics Power semiconductor devices have a maximum power dissipation rating usually quoted at a case temperature of . The datasheet for the device also includes a ''derating curve'' which indicates how much a device will dissipate without getting damaged at any given case temperature, and this must be taken into account while designing a system. As can be seen from the derating curve image for a hypothetical bipolar junction transistor, the device (rated for 100 W at ) cannot be expected to dissipate anything more than about 40 W if the ambient temperature is such that the temperature at which the device's case will stabilize (after heat-sinking) is . This final case temperature is a function of the thermal resistance between the device's case and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lycoming ALF 502
The Lycoming ALF 502/LF 507 (later Honeywell ALF 502/LF 507) is a geared turbofan Aircraft engine, engine produced by Lycoming Engines, AlliedSignal, and Honeywell Aerospace. The U.S. military designation for the ALF 502 is YF102. Development In mid-1970, Avco Lycoming was advertising two Lycoming T55-derived engines, an LTC4B-12 turboprop and an ALF 502A turbofan, as possible powerplants for the U.S. Air Force's A-X close air support aircraft program. Northrop Corporation signed a contract with Avco Lycoming to use the ALF 502A for its entry into the A-X competition, the Northrop YA-9, in January 1971. The engine was given a United States military aircraft engine designation of YF102-LD-100. Six YF102 engines were built for the YA-9. The thrust engines powered the A-9A prototypes for seven months of flight tests in 1972, recording 238 flights and 652 flight hours. These engines were later reused in the C-8A Quiet Short-Haul Research Aircraft (QSRA). The commercial ALF 502D e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DASA
DASA (officially Deutsche AeroSpace AG, later Daimler-Benz AeroSpace AG, then DaimlerChrysler AeroSpace AG) was a German aerospace manufacturer. It was created during 1989 as the aerospace subsidiary arm of Daimler-Benz, Daimler-Benz AG (later DaimlerChrysler) from 1989. The company acquired rival manufacturer Messerschmitt-Bölkow-Blohm (MBB) that same year, integrating it along with its other aerospace interests, MTU Aero Engines, MTU München, and Dornier Flugzeugwerke, by 1992. The company's existence was relatively brief due to the peace dividend of the 1990s having motivated industry-wide consolidation. During July 2000, DASA merged with Aérospatiale-Matra of France and CASA (aircraft manufacturer), Construcciones Aeronáuticas SA (CASA) of Spain to form Airbus, EADS, which has since rebranded itself as ''Airbus Group''.
