Northrop XFT
The Northrop XFT was an American prototype fighter aircraft of the 1930s. A single engined low-winged monoplane, it was designed and built to meet a United States Navy order for an advanced carrier based fighter. It exhibited poor handling, and was rejected by the Navy, the single prototype being lost in a crash. A variant, the Northrop 3A, also was unsuccessful. Development and design In the early 1930s, the United States Navy was interested in investigating the use of modern, monoplanes as fighter aircraft to replace the biplanes that equipped its fighter squadrons. In December 1932, it ordered the XF7B from Boeing, and based on the impressive performance of Northrop's Gamma and Delta, both stressed skin monoplanes, placed an order with Northrop on May 8, 1933 for a single prototype fighter, designated XFT-1.Green and Swanborough 1994, pp.454-455.Francillion 1979, p.173. The resulting aircraft, which was designed by a team led by Ed Heinemann resembled a scaled-down North ... [...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 ...

Wright Whirlwind
The Wright Whirlwind was a family of air-cooled radial aircraft engines built by Wright Aeronautical (originally an independent company, later a division of Curtiss-Wright). The family began with nine-cylinder engines, and later expanded to include five-cylinder and seven-cylinder varieties. Fourteen-cylinder twin-row versions were also developed, but these were not commercially produced. The Whirlwind series was succeeded by more powerful but still air-cooled radial aero engines, notably the Pratt & Whitney Wasp series and the Wright Cyclone series. Description The Whirlwind was a direct descendant of the Lawrance J-1, a nine-cylinder air-cooled radial built by the Lawrance Aero Engine Company for the U.S. Navy. Because the Navy was very enthusiastic about air-cooled radials, but was concerned that Lawrance could not produce enough engines for its needs, it forced Wright to purchase the Lawrance company in 1923 and build the J-1 itself. Wright's J-1 was the first engine in its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blueprint
A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterized by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey. The process is now obsolete. It was first largely displaced by the diazo whiteprint process, and later by large-format xerographic photocopiers. The term ''blueprint'' continues to be used less formally to refer to any floor plan (and even less formally, any type of plan). Practicing engineers, architects, and drafters often call them "drawings", “prints”, or “plans”. It has almost entirely been replaced with digital computer-aided ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a commissioned officer rank in the armed forces of many nations. The meaning of lieutenant differs in different militaries (see comparative military ranks), but it is often subdivided into senior (first lieutenant) and junior (second lieutenant and even third lieutenant) ranks. In navies, it is often equivalent to the army rank of captain; it may also indicate a particular post rather than a rank. The rank is also used in fire services, emergency medical services, security services and police forces. Lieutenant may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is " second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieutenant governor in various g ...

Test Pilot
A test pilot is an aircraft pilot with additional training to fly and evaluate experimental, newly produced and modified aircraft with specific maneuvers, known as flight test techniques.Stinton, Darrol. ''Flying Qualities and Flight Testing of the Airplane.'' American Institute of Aeronautics and Astronautics, Inc., 1996, p. 265 History Test flying as a systematic activity started during the First World War, at the Royal Aircraft Establishment (RAE) in the United Kingdom. An "Experimental Flight" was formed at the Central Flying School. During the 1920s, test flying was further developed by the RAE in the UK, and by the National Advisory Committee for Aeronautics (NACA) in the United States. In the 1950s, NACA was transformed into the National Aeronautics and Space Administration, or NASA. During these years, as work was done into aircraft stability and handling qualities, test flying evolved towards a more qualitative scientific profession. In the 1950s, test pilots were ...

Allegheny Mountains
The Allegheny Mountain Range (; also spelled Alleghany or Allegany), informally the Alleghenies, is part of the vast Appalachian Mountain Range of the Eastern United States and Canada and posed a significant barrier to land travel in less developed eras. The Allegheny Mountains have a northeast–southwest orientation, running for about from north-central Pennsylvania, southward through western Maryland and eastern West Virginia. The Alleghenies comprise the rugged western-central portion of the Appalachians. They rise to approximately in northeastern West Virginia. In the east, they are dominated by a high, steep escarpment known as the Allegheny Front. In the west, they slope down into the closely associated Allegheny Plateau, which extends into Ohio and Kentucky. The principal settlements of the Alleghenies are Altoona, State College, and Johnstown, Pennsylvania; and Cumberland, Maryland. Name The name is derived from the Allegheny River, which drains only a small porti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Segundo, California
El Segundo ( , ; ) is a city in Los Angeles County, California, United States. Located on Santa Monica Bay, it was incorporated on January 18, 1917, and is part of the South Bay Cities Council of Governments. The population was 16,731 as of the 2020 census, a 0.5% increase from 16,654 in the 2010 census. History The El Segundo and Los Angeles coastal area was first settled by the Tongva (or Gabrieleños) Native American tribes thousands of years ago. The area was once a part of ''Rancho Sausal Redondo'' ("Round Willow Patch Ranch"). Rancho Sausal Redondo extended from Playa Del Rey in the north to Redondo Beach in the south. Originally a Mexican land grant owned by Antonio Ygnacio Avila, the rancho was later purchased by a Scottish baronet named Sir Robert Burnett. After his return to Scotland, the property was purchased by then-manager of the rancho, Daniel Freeman. Daniel Freeman sold portions of the rancho to several persons. George H. Peck owned the of land where the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vance Breese
Vance Breese (1904–1973) was an American Aeronautical engineer, aviation engineer and test pilot. Early years Vance Breese was born in Keystone, Washington, on April 20, 1904. His education, in his own words was: "various engineering extension courses." More than an engineer, he devoted his life to aviation. Aviation career In 1926, Breese founded the (Vance) Breese Aircraft Company at Mills Field, San Francisco and was its president, from 1927 to 1934. Competing in the 1926 National Air Tour, flying a Ryan M-1 monoplane with a Wright J-4 engine, he finished in eighth place, although he had actually been in first place when he reached Cleveland, Ohio, one of 14 cities in the competition. During the 15-day event which was the second annual commercial airplane reliability tour, Breese carried J. B. Alexander and A. L. Hufford as passengers. Aviation companies The companies that Breese operated, appeared under various names, in 1927 as the Breese-(Arthur F. "Pop") Wilde Aircraft ...
