Eclipse 400
The Eclipse 400 (formerly Eclipse Concept Jet, or ECJ) is a single-engine very light jet that was designed by Eclipse Aviation of Albuquerque, New Mexico. A development of the Eclipse 500, the Eclipse 400 was cancelled when the company went bankrupt in 2008 and development has not been pursued by Eclipse Aerospace, the company that bought Eclipse Aviation's assets. Design and development The Eclipse 400 was first publicly unveiled on 23 July 2007 at AirVenture as the Eclipse Concept Jet (ECJ). The aircraft was intended to compete with the Cirrus Vision SF50, the Piper PA-47 PiperJet, the Epic Victory, and the Diamond D-Jet in the single-engine jet market. The Eclipse 400 design featured one engine, four seats and a V-tail similar to the Cirrus Jet. The four-seat prototype, registered N5184U, is powered by a single Pratt & Whitney Canada PW610F turbofan, first flown on 2 July 2007. It was built in complete secrecy at NASA's Wallops Flight Facility in Virginia by Swift Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

V-tail Aircraft
The V-tail or ''Vee-tail'' (sometimes called a butterfly tail or Rudlicki's V-tailGudmundsson S. (2013). "General Aviation Aircraft Design: Applied Methods and Procedures" (Reprint). Butterworth-Heinemann. p. 489. , 9780123973290) of an aircraft is an unconventional arrangement of the tail control surfaces that replaces the traditional fin and horizontal surfaces with two surfaces set in a V-shaped configuration. It is not widely used in aircraft design. The aft edge of each twin surface is a hinged control surface called a ruddervator, which combines the functions of both a rudder and elevator. The V-tail was invented in 1930 by Polish engineer Jerzy Rudlicki and was tested for the first time on the Hanriot H-28 trainer aircraft, modified by a Polish aerospace manufacturer Plage and Laśkiewicz in the summer of 1931. Variants The X-shaped tail surfaces of the experimental Lockheed XFV were essentially a V tail that extended both above and below the fuselage. Conventional T ...

Very Light Jets
A very light jet (VLJ), entry-level jet or personal jet, previously known as a microjet, is a category of small business jets seating four to eight people. VLJs are considered the lightest business jets and are approved for single-pilot operation. History The first small jet-powered civil aircraft, the 1950s Morane-Saulnier MS.760 Paris, has been retroactively suggested as being the first VLJ, as it seats four with a single pilot and is smaller than modern VLJs. The production of MS.760 differs from modern business jets in having a sliding canopy for cabin access rather than a door; a six-seat version with an enclosed cabin and a conventional door was canceled after a single prototype was built. Two unbuilt Cessna aircraft of the 1950s and 1960s would have met the definition of a VLJ. The first was the 407, a four-seat civil version of the T-37 jet trainer proposed in 1959; however, the 407 never progressed past the mockup stage due to insufficient customer interest. The secon ...

2000s United States Civil Utility Aircraft
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the ...

Eclipse Aircraft
An eclipse is an astronomical event that occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden). The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chapter 7 Liquidation
Chapter 7 of Title 11 of the United States Code (Bankruptcy Code) governs the process of liquidation under the bankruptcy laws of the United States, in contrast to Chapters 11 and 13, which govern the process of ''reorganization'' of a debtor. Chapter 7 is the most common form of bankruptcy in the United States. For businesses When a troubled business is unable to pay its creditors, it may file (or be forced by its creditors to file) for bankruptcy in a federal court under Chapter 7. A Chapter 7 filing means that the business ceases operations unless those operations are continued by the Chapter 7 trustee. A Chapter 7 trustee is appointed almost immediately, with broad powers to examine the business's financial affairs. The trustee generally liquidates the assets and distributes the proceeds to the creditors. This may or may not mean that all employees will lose their jobs. When a large company enters Chapter 7 bankruptcy, entire divisions of the company may be sold intac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EclipseJet Aviation International
The Eclipse Aviation Corporation was the Albuquerque, New Mexico, United States-based manufacturer of the Eclipse 500 very light jet (VLJ), and also at one time proposed developing the Eclipse 400 single-engined jet. The company was founded in 1998 by early Microsoft employee and former Symantec CEO Vern Raburn. Due to Raburn's relationship with Microsoft, Bill Gates was a major stake-holder in the Eclipse project. The company was known for helping usher in a new category of VLJs when the Eclipse 500 was first delivered in late 2006. In October 2008, production of the Eclipse 500 was halted due to lack of funding. The company entered an unsuccessful Chapter 11 bankruptcy in November 2008, which was converted into a Chapter 7 bankruptcy liquidation procedure in February 2009. In the final Chapter 7 procedure, completed on August 20, 2009, there was only one bidder, a new company formed to acquire the assets, Eclipse Aerospace. Eclipse operated service centers at Albuquerque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chapter 11, Title 11, United States Code
Chapter 11 of the United States Bankruptcy Code (Title 11 of the United States Code) permits reorganization under the bankruptcy laws of the United States. Such reorganization, known as Chapter 11 bankruptcy, is available to every business, whether organized as a corporation, partnership or sole proprietorship, and to individuals, although it is most prominently used by corporate entities. In contrast, Chapter 7 governs the process of a liquidation bankruptcy, though liquidation may also occur under Chapter 11; while Chapter 13 provides a reorganization process for the majority of private individuals. Chapter 11 overview When a business is unable to service its debt or pay its creditors, the business or its creditors can file with a federal bankruptcy court for protection under either Chapter 7 or Chapter 11.
