Slingsby Skylark 4
The Slingsby T.50 Skylark 4 was a British single seat competition glider built by Slingsby Sailplanes in the early 1960s. It sold in numbers and had success at national, though not world level competition. Development The Slingsby Skylark 4 is the final development of the Skylark series of gliders and was first manufactured in 1961 using an 18.2m span wing similar to that of the Skylark 3. About 30 Skylark 4s are still flying today (2010). Slingsby had introduced double curvature fuselage panels made of glass reinforced plastic (GRP) into their previous design, the T.49 Capstan and they remodelled the front of the wooden fuselage of the Skylark 3 in this material for the Skylark 4, introducing a reclining pilot's position and smoother canopy line. Though the previous wing planform, span and area was retained, its ailerons were extended to increase the rate of roll and the outer panels used a different airfoil section, the more cambered NACA 6415, to give a better lift dis ...

Junín, Buenos Aires
Junín () is a city in the province of Buenos Aires, Argentina, and administrative seat of the '' partido'' of Junín. It has a population of 85,420 () and is located west of the city of Buenos Aires. It is mostly known for being the hometown of former first lady of Argentina Eva Perón. History Inhabited by the native Charrúa people, the site's strategic location on the Salado River made it of interest to Spanish Viceroy Juan José de Vértiz y Salcedo, who established an outpost there in the 1790s as part of a line of defense against raids by displaced natives. The location became known as ''El Potroso''. El Potroso was reinforced by a fort by way of an 1826 decree by President Bernardino Rivadavia, and on December 27, 1827, the citadel was established under the command of a veteran of the Argentine War of Independence, Bernardino Escribano, as ''Fuerte de la Federación''. The advent of Buenos Aires Province Governor Juan Manuel de Rosas led to Escribano's 1829 destituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1960s British Sailplanes
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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.

Slingsby Dart
The Slingsby Type 51 Dart is a single seat competition glider designed in the early 1960s, initially as a 15 m span Standard Class aircraft but evolved into an Open Class, 17 m sailplane. It was the last Slingsby sailplane to be mostly constructed of wood. Development The Slingsby Dart was the last of a long line of gliders and sailplanes built by Slingsby Sailplanes Ltd almost entirely from wood. From the Slingsby Skylark 2 of 1953 onwards, the company had used Gaboon ply, thicker but less dense than the traditional birch for surfacing wings and fuselage, as it gave a smoother surface capable of maintaining the more demanding profiles of the newer aerofoils. The Capstan flew ten years later with double curvature parts of the fuselage skin produced from glass-reinforced plastic (G.R.P). Combined, these were the construction methods initially used for the Dart. The Dart was originally a 15 m sailplane, aimed immediately at the 1964 UK Gliding Championships and beyond at ...

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] |

Dick Johnson (glider Pilot)
Richard H. Johnson (January 10, 1923 – July 23, 2008) was a glider pilot, aeronautical engineer and prolific writer of articles for gliding magazines. He was an 11-time U.S. National Champion glider pilot, 9-time US Soaring Team pilot at the Soaring World Championships, held two World Gliding Records and is a member of the US Soaring Hall of Fame. He flew for 70 years and logged over 14,000 flying hours, including over 10,000 hours of non-powered flight time in sailplanes. He authored over 100 articles on soaring and flight tests of gliders. Early years Dick Johnson was born on January 10, 1923 in Medicine Hat, Alberta, Canada. He grew up in Los Altos, California, where he learned the basics of flight and aerodynamics as a model airplane and glider enthusiast. He won the California State Hand-Launched Model Glider Championship in 1937. In 1938, wanting to graduate to full-size aircraft, Johnson read Wolf Hirth's book ''The Art of Soaring Flight'' three times. Using a ...

South Cerney
South Cerney is a village and civil parish in the Cotswold district of Gloucestershire, 3 miles south of Cirencester and close to the border with Wiltshire. It had a population of 3,074 according to the 2001 census, increasing to 3,464 at the 2011 census. It was founded in 999 by Saxon settlers, with a charter by King Aethelred II. In 2001 South Cerney was winner of the Bledisloe Cup for the best-kept village in Gloucestershire (large village class), having previously won the award in 1955. Church of All Hallows, South Cerney and Ann Edwards School Two fragments of a carved wooden crucified Christ, a head and a foot, were found in 1915 concealed in a wall of the village church. The crucifix was probably hidden at the time of the Reformation but mostly disintegrated due to the damp. Part of a crucifix that dates from the 12th century, it is one of very few early-medieval wooden sculptures of Christ extant in England, and would have been part of the 'rood' that stood above ...

World Gliding Championships
The World Gliding Championships (WGC) is a gliding competition held every two years or so by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are sometimes held in the summer in the Southern Hemisphere. History Gliding had been a demonstration sport at the 1936 Summer Olympics and was due to become an official Olympic sport in the Helsinki Games in 1940. However, since the Second World War, gliding has not featured in the Olympics, and so the World Championships are the highest level in the sport. There are now contests for six classes of glider and so in recent years the Championships have been divided between two locations. The women's, junior, grand prix and aerobatic events are also held separately. Each of the following entries give the year and location of the contest followed by the winner of each class, nationality and the glider used.
