Instituto De Pesquisas Tecnologicas IPT-16 Surubim
The IPT-16 Surubim was a Brazilian single-seat, single engined experimental light aircraft. A single example was built and flown in 1959. Design and development In 1949, Joseph Kovács, a Hungarian-born aircraft engineer working at the ''Instituto de Pesquisas Tecnologicas'' (IPT - Institute of Technical Research) of the University of São Paulo proposed to design and build an experimental high performance light aircraft powered by a surplus Hirth HM 506 engine that had been imported into Brazil before the Second World War for use in an unbuilt aircraft design. The IPT, however, was busy on other projects, and so did not back Kovács' proposed design. Kovács, with fellow IPT engineer Sylvio de Oliveira, started construction of the design, named "Surubim" (little devil), in a rented workshop. The Surubim was a low-winged monoplane with a retractable tailwheel undercarriage of all wooden construction with plywood skinning, using Brazilian Pine and Freijo, two indigenous wood ...

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".

Flap (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

1950s Brazilian Civil Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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. Events By place Roman Empire * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger. The Roman province of Mesopotamia rises in revolt with Parthian support. Severus marches to Mesopotamia to battle the Parthians. * The Roman province of Syria is divided and the role of Antioch is diminished. The Romans annexed the Syrian cities of Edessa and Nisibis.

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Museu Aeroespacial
Museu Aeroespacial is a national aviation museum located in the West Side of Rio de Janeiro, Brazil in the Administrative Region of Realengo. The place is known as "the Brazilian Aviation cradle".Ogden (2008) Address Av. Marechal Fontenelle, 2000 - Campo dos Afonsos (Realengo), Rio de Janeiro/RJ History The Museu Aeroespacial (Aerospace Museum) was inaugurated on 18 October 1976 at the installations of the old Escola de Aeronáutica (former Brazilian Air Force officer graduation school, replaced by the Academia da Força Aérea), at Afonsos Air Force Base—the "Cradle of Military Aviation", in the City of Rio de Janeiro, Estado do Rio de Janeiro, Brazil. The idea of an "Aeronautical Museum" dates from 1943 when the Minister of Aeronautics, Dr. Salgado Filho, determined its organization, but the initial work and subsequent attempts were interrupted by lack of suitable space and installations. Given the explanatory memorandum from Lieutenant Brigadier Joelmir Campos do Araripe M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leading Edge Slot
A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface. In this manner they allow flight at higher angles of attack and thus reduce the stall speed. Purpose and development At an angle of attack above about 15° many airfoils enter the stall. Modification of such an airfoil with a fixed leading-edge slot can increase the stalling angle to between 22° and 25°.Clancy, L.J., ''Aerodynamics'', Section 6.9 Slots were first developed by Handley Page in 1919 and the first aircraft to fly with them was the experimental H.P.17, a modified Airco DH.9A. Their invention is credited jointly to Sir Frederick Handley Page and Gustav Lachmann. The first aircraft fitted with controllable slots was the Handley Page H.P.20. Licensing the design became one of Handley Page's major sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordia Alliodora
''Cordia alliodora'' is a species of flowering tree in the borage family, Boraginaceae, that is native to the American tropics. It is commonly known as Spanish elm, Ecuador laurel, cypre or salmwood. It can reach 35 m in height. Uses ''Cordia alliodora'' is one of several ''Cordia'' trees called ''bocote'' in Spanish and its wood, which has very little figure, is usually called freijo or jennywood along with that of '' Cordia goeldiana''. The wood is used for boat decking, furniture, cabinetry, guitar/bass building by luthiers, and sometimes substitutes for mahogany or teak. Environmental aspects Outside of its indigenous range, ''Cordia alliodora'' has been identified as a problematic invasive species. For example, a timber-focused planting program of the species in Vanuatu during the mid-1970s has over time proved disruptive to native ecosystems and communities. The species has been described as a severe environmental nuisance, as it has overtaken natural forests by multiply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
