Douglas R3D
The Douglas DC-5 (Douglas Commercial Model 5) was a 16-to-22-seat, twin-engine propeller aircraft intended for shorter routes than the Douglas DC-3 or Douglas DC-4. By the time it entered commercial service in 1940, many airlines were canceling orders for aircraft. Consequently, only five civilian DC-5s were built. With the Douglas Aircraft Company already converting to World War II military production, the DC-5 was soon overtaken by world events, although a limited number of military variants were produced. Design and development The DC-5 was developed in 1938 as a 16-22 seat civilian airliner, designed to use either Pratt & Whitney R-1690 Hornet or Wright R-1820 Cyclone radial engines. It was the first airliner to combine shoulder wings and tricycle landing gear, a configuration that is still common in turboprop airliners and military transport aircraft, although the modern versions are actually high wing, as the structure sits atop the fuselage shell rather than intersecting ...

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".

Tricycle Landing Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCADTA
Sociedad Colombo Alemana de Transportes Aéreos german: Deutsch-Kolumbianische Luftverkehrsgesellschaft), or SCADTA, was the world's second airline, and the first airline in Latin America, operating from 1919 until World War II. After the war, SCADTA merged with Colombian regional carrier Colombian Air Service ( es, Servicio Aéreo Colombiano), or SACO. Together, SCADTA and SACO formed Avianca - Aerovías Nacionales de Colombia, the Colombian flag-carrier. Avianca still operates to this day and claims SCADTA's history as its own, thus making it the world's second-oldest active airline, after KLM from the Netherlands. History SCADTA started out as a small airmail carrier using Junkers seaplanes capable of landing on Colombia's Magdalena River, mostly since there were very few suitable landing strips in Colombia at the time. The German nationality of some of SCADTA's owners motivated the United States government to subsidize Pan American World Airways' expansion in Latin America ...

Capital Airlines (United States)
Capital Airlines was an airline serving the eastern, southern, southeastern, and midwestern United States. Capital's headquarters were located at Washington National Airport (now Reagan Washington National Airport) across the Potomac river from Washington, D.C. where crew training and aircraft overhauls were also accomplished. In the 1950s Capital was the fifth largest United States domestic carrier by passenger count (and sometimes by passenger-miles) after the Big Four air carriers (American, United, TWA, and Eastern).''

William Boeing
William Edward Boeing (; October 1, 1881 – September 28, 1956) was an American aviation pioneer who founded the Pacific Airplane Company in 1916, which a year later was renamed to The Boeing Company, now the largest exporter in the United States by dollar value and among the largest aerospace manufacturers in the world. William Boeing's first design was the Boeing Model 1 (or B & W Seaplane), which first flew in June 1916, a month before the company was founded. He also helped create the United Aircraft and Transport Corporation (known as "United Airlines" today) in 1929 and served as its chairman. He received the Daniel Guggenheim Medal in 1934 and was posthumously inducted in to the National Aviation Hall of Fame in 1966, ten years after his death. Early life William Boeing was born in Detroit, Michigan, to Marie M. Ortmann, from Vienna, Austria, and Wilhelm Böing (1846–1890) from Hohenlimburg, Germany. Wilhelm Böing emigrated to the United States in 1868 and initial ... [...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.

Nacelle
A nacelle ( ) is a "streamlined body, sized according to what it contains", such as an engine, fuel, or equipment on an aircraft. When attached by a pylon entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French, in this case from a word for a small boat. Development The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles. During its development, the four jet engines were merged from having four distinct nacelles, all of which contained their own landing gear wheel, to two nacelles with two engi ...

Strake (aeronautics)
In aviation, a strake is an aerodynamic surface generally mounted on the fuselage of an aircraft to improve the flight characteristics either by controlling the airflow (acting as large vortex generators) or by a simple stabilising effect. In general a strake is longer than it is wide, in contrast to a winglet or a moustache. Leading edge root extensions (LERX) are also sometimes referred to as wing strakes. Nose strakes On both supersonic and subsonic types, smaller strakes are sometimes applied to the forward fuselage to control the fuselage flow at high angles of attack; for example, the Concorde SST had small nose strakes "to get a better directional stability". Wing strakes Double delta wing aircraft (Concorde, Tupolev Tu-144, Boeing 2707 SST project) featured a forward extended leading edge that may be considered as a wing strake; it provides the same additional vortex lift at high angle of attack by leading edge suction. Nacelle strakes On jet aircraft where the en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihedral (aeronautics)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
