DN-1 (airship)
The DN-1 was the United States Navy's first airship. Development Captain Mark L. Bristol, the second Director of Naval Aviation, supported the development of the dirigible in the anti-submarine role.Grossnik, Roy A. 1986 ''Kite Balloons to Airships . . . the Navy's Lighter-than-Air Experience'', Washington D.C.: Deputy Chief of Naval Operations (Air Warfare) and the Commander, Naval Air Systems Command, p. 3. Victor Herbster, Holden Richardson and LCDR Frank McCrary drew up the specifications for the DN-1. The contract was awarded on 1 June 1915 to the Connecticut Aircraft Company of New Haven, CT.Clark, Basil, ''The History of Airships'', New York: St Martin's Press, 1961, Library of Congress 64-12336, p. 146. The U.S. Navy had no experience with airships and it seems neither had any of the principals of Connecticut Aircraft Company. They were a lawyer who was the financial backer, an amusement park owner who acted as manager; the technical staff was an Austrian, Hans Otto S ...

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 Wikimedia project, 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 Magazine, 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".

1910s United States Patrol Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 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.

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between bracke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jane's All The World's Aircraft
''Jane's All the World's Aircraft'' (now stylized Janes) is an aviation annual publication founded by John Frederick Thomas Jane in 1909. Long issued by Sampson Low, Marston in Britain (with various publishers in the U.S.), it has been published by Janes Information Services since 1989/90. The first volume's title referred to "airships" while all since have referenced "aircraft". After World War I, the format of the book shifted from an oblong ("landscape") format to the present "portrait" orientation. With the 1993/94 edition, the book was divided into two volumes that continue to appear annually. The main volume focuses on aircraft in production while the second book describes older aircraft and upgrades, both military and civil. While 2009 was the centennial year of ''Jane's All the World's Aircraft'', 2013 marked the 100th edition—the disparity due to disruptions (chiefly with volumes covering two years) during the two World Wars. Starting in 1969, Arco (New York) issued the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lift (force)
A fluid flowing around an object exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the force parallel to the flow direction. Lift conventionally acts in an upward direction in order to counter the force of gravity, but it can act in any direction at right angles to the flow. If the surrounding fluid is air, the force is called an aerodynamic force. In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy, in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines. Planing lift, in which only the lower portion of the body is immersed in a liquid flow, is used by motorboats, surfboards, windsurfers, sailboats, and water-skis. Overview A fluid flowing aro ...

Mooring Mast
A mooring mast, or mooring tower, is a structure designed to allow for the docking of an airship outside of an airship hangar or similar structure. More specifically, a mooring mast is a mast or tower that contains a fitting on its top that allows for the bow of the airship to attach its mooring line to the structure. When it is not necessary or convenient to put an airship into its hangar (or shed) between flights, airships can be moored on the surface of land or water, in the air to one or more wires, or to a mooring mast. After their development mooring masts became the standard approach to mooring airships as considerable manhandling was avoided.Williams, T, 2009 (Reissue), "Airship Pilot No. 28", Darcy Press, UK, Mast types Airship mooring masts can be broadly divided into fixed high masts and fixed or mobile low (or ‘stub’) masts. In the 1920s and 1930s masts were built in many countries. At least two were mounted on ships. Without doubt the tallest mooring mas ...
