Slingsby T.25 Gull 4
The Slingsby T.25 Gull 4 is a British glider designed and built by Slingsby that first flew in 1947. Development After the Second World War Slingsby wished to produce a high-performance sailplane to be used in the Olympic games. The German DFS Meise, renamed Olympia, had already been chosen as the standard aircraft for the abandoned 1940 games and was produced in large quantities in several countries. The licence for the 'Olympia' was held by the Chilton Aircraft Company so Slingsby had no choice but to design his own version. Due to the identical specification and the use of state of the art construction the Gull 4 emerged with very similar features to the Olympia. A replacement for the Kite 2 was proposed as the T.32 Gull 4B, but this glider did not reach the hardware stage. Design The fuselage was of semi-monocoque wooden construction with plywood skinning throughout over longerons and built up frames, most of which were shared with the Slingsby T.26 Kite 2. The wing was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Engli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slingsby Aviation
Slingsby Aviation was a British aircraft manufacturer based in Kirkbymoorside, North Yorkshire, England. The company was founded to design and build gliders and sailplanes. From the early 1930s to around 1970 it built over 50% of all British club gliders and had success at national and international level competitions. It then produced some powered aircraft, notably the composite built Firefly trainer, before becoming a producer of specialised composite materials and components. The business is now known as Marshall Advanced Composites and produces composite parts for ships, submarines and aircraft. It is a subsidiary of Marshall of Cambridge. History The business was founded in Scarborough by Frederick Nicholas Slingsby, an RAF pilot in World War I. In 1920 he bought a partnership in a woodworking and furniture factory in Queen Street, Scarborough. In 1930 Slingsby was one of the founders of the Scarborough Gliding Club. After repairing some of the club's gliders, Sling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DFS Meise
The DFS Olympia Meise (German: "Olympic Titmouse") was a German sailplane designed by the Deutsche Forschungsanstalt für Segelflug (DFS) for Olympic competition, based on the DFS Meise. Design and development After the Olympic games in Berlin in 1936 introduced gliding as an Olympic sport, plans were made to fly the 1940 Olympic championships with a standard design of sailplane to give each pilot the same chances. The Meise was redesigned to fit into the new Olympic class specifications. The new 'Olympia' Meise had the prescribed wingspan of 15 m (49 ft 2 in), spoilers, but no flaps, and an undercarriage consisting of a skid and a non-retractable wheel. The pilot sat all-enclosed in an aerodynamically clean fuselage made of laminated wood and topped by an acrylic glass hood. The plane could be launched by winch as well by towplane. Its wood-and-fabric construction made it easy for flying clubs to maintain, to repair and even to build the gliders from kits. A design cont ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
