SAB-SEMA 12
The SAB-SEMA 10 was a single-engine advanced trainer, designed and built in France as the SEMA 10, in the 1930s. It failed to win a French production contract and only one was built. Re-engined, modified and redesignated SAB-SEMA 12, it served with the Spanish Republican Air Force at the beginning of the Spanish Civil War. Design and development The SAB-SEMA 10 was designed by the ''Societé d'Etudes de Materiel d'Aviation'' (SEMA) and built by the ''Société Aérienne Bordelaise'' (SAB) to compete for a 1933 French government contract for an intermediate and advanced military trainer. It was a conventional biplane, metal framed and fabric covered, powered by a 240 hp (180 kW) Lorraine 7Mc Mizar seven-cylinder radial engine. Instructor and pupil occupied open tandem cockpits. The SAB-SEMA 10 failed to gain a production contract when the competition was won by the Romano R.82. It was then re-engined with a more powerful 300 hp (224 kW) Lorraine 9Na Algo ...

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 ...

Ailerons
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in Flight dynamics, roll (or movement around the aircraft's Flight control surfaces#Longitudinal axis, longitudinal axis), which normally results in a change in flight path due to the tilting of the Lift (force), lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long Wright brothers patent war, legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the World War I, First World War compelled the U.S. Government to legislate a le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

1930s French Military Trainer Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

List Of Aircraft Of The Spanish Republican Air Force
This is a list of aircraft used by the Spanish Republican Air Force during the Spanish Civil War. Introduction The Second Spanish Republic was proclaimed in 1931 and very soon the republican authorities set up to reform an antiquated military structure that was a financial burden for the Spanish state following the Great Depression. The Spanish Republican Air Force inherited a great number of airplanes from the monarchy, most of which had been used in the Spanish Campaigns in Northern Africa during general Primo de Rivera's dictatorship in the 1920s. Hostile to the republican reforms, and with many of its top echelon officers sympathizing with the far-right movements of Nazi Germany and Fascist Italy, part of the military elite staged a failed coup led by General Sanjurjo in 1934. However, the rebellion led by General Franco against the Spanish Republic in 1936 was more successful and marked the beginning of the Spanish Civil War. While more than half of the aircraft of the Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Los Alcázares
Los Alcázares () is a municipality and a coastal spa town and former fishing village on the western side of the Mar Menor in the autonomous community and province of Murcia, southeastern Spain. The Mar Menor (little sea) belongs to three other municipalities: San Javier, San Pedro del Pinatar and Cartagena and is Europe's largest saltwater lagoon. Connected to the adjacent Mediterranean sea by several channels, the Mar Menor has a surface area of almost 20 km2 and the fact that it is typically 2-4 degrees warmer than the Mediterranean, makes it a very popular destination for sailing, windsurfing, kiteboarding and other water sports enthusiasts. Los Alcazares has a resident population (2018) of 15,674 which rises to over 100,000 during the peak tourist summer holiday season. On 13 October 1983, the town was granted municipal autonomy, in respect of which it holds an annual week-long celebration featuring live music, shows, windsurfing competitions and firework displays. ...

Fairing (aircraft)
An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: ''Dictionary of Aeronautical Terms, Third Edition'', page 206. Aviation Supplies & Academics Inc, Newcastle Washington, 1997. These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.Bingelis, Tony: ''The Sportplane Builder'', pages 261-265. Experimental Aircraft Association Aviation Foundation, 1979. Types On aircraft, fairings are commonly found on: ; Belly fairing : Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks. ; Cockpit fairing : Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-17. Cybair ...

Conventional Undercarriage
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
