Slingsby T.9 King Kite
The Slingsby T.9 King Kite is a British glider designed and built by Slingsby that first flew in 1937. Design and development ISTUS (international commission for the study of motorless flight) launched a campaign for gliding's inclusion in the Olympic games, organising an international competition, planned for 4–17 July 1937 for aspiring national teams. The British Gliding Association (BGA) were in a quandary as the only suitable aircraft was the Buxton Hjordis. To replace it Mungo Buxton had started the design of the Hjordis 2 but due to his commitments as a serving RAF officer Buxton handed over the design to Slingsby, Sproule and Shaw to complete the aircraft. Buxton had studied the latest soaring techniques and came to the conclusion that competitive aircraft would need to fly efficiently at higher speeds and not sacrifice glide performance for climb performance. The result of their efforts, the Slingsby Type 9 King Kite, emerged as a cantilevered gull wing sailplane w ... [...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 very low 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 either ...

Flap (aircraft)
A flap is a high-lift device used to reduce the stall (flight), 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 (physics), 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 (fluid dynamics), stall of the outbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1930s British Sailplanes
Year 193 ( CXCIII) was a common year starting on Monday 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.

NACA Airfoil
The NACA airfoil series is a set of standardized airfoil shapes developed by this agency, which became widely used in the design of aircraft wings. 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 (aerodynamics), camber as percentage of the Chord (aircraft), 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 leading edge with a maximum thickness of 12% of the chord. The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The 15 indicates that the airfoil has a 15% thick ...

Royal Air Force Gliding & Soaring Association
The Royal Air Force Gliding & Soaring Association (RAFGSA) is a voluntary organisation which exists to provide recreational flying to all RAF servicemen and women, in particular those employed in ground duties. RAFGSA Centre The RAFGSA Centre is at RAF Halton. It has a full-time staff to provide central organisational, training and workshop facilities. The Joint Services Gliding Centre (JSGC) is co-located at Halton. It is part of the Joint Service Adventurous Training (JSAT) Air Sports organisation which provides training courses for military personnel. History In 1945, the British Air Forces of Occupation (BAFO) in Germany began using captured German gliders to provide recreational flying for RAF personnel. This resulted in a demand for similar facilities in the United Kingdom, and the Royal Air Force Gliding & Soaring Association was founded in 1949. The first aircraft, a Slingsby T.21 and a Prefect, were bought in March 1950 and stationed at RAF Detling. By 1952 27 g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spin (aerodynamic)
In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a crash may require a specific and counter-intuitive set of actions. A spin differs from a spiral dive, in which neither wing is stalled an ...

Philip Wills
Philip Aubrey Wills CBE (26 May 1907 – 16 January 1978)Fripp UK genealogy was a pioneering British glider pilot. He broke several UK gliding records from the 1930s to the 1950s and was involved in UK gliding administration including being Chairman of the British Gliding Association (BGA). In World War II he was second in command of the Air Transport Auxiliary and for this work was appointed CBE. After the war he was chairman of the BGA for 19 years, and in 1952 he was Open Class World Champion in the world gliding championships in Spain. In 1964 he was awarded the Lilienthal Gliding Medal of the Fédération Aéronautique Internationale (FAI) for services to gliding. He was a member of the British Gliding Team until 1958. Early years Philip Wills was from a wealthy family in the shipping and export business.

Spar (aviation)
In a fixed-wing aircraft, the spar is often the main structural member of the wing, running wingspan, spanwise at right angles (or thereabouts depending on Swept wing, wing sweep) to the fuselage. The spar carries flight Structural load, loads and the weight of the wings while on the ground. Other structural and forming members such as Rib (aircraft), ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all. Where a single spar carries most of the force, it is known as the main spar. Spars are also used in other aircraft airfoil, aerofoil surfaces such as the tailplane and Vertical stabilizer, fin and serve a similar function, although the loads transmitted may be different from those of a wing spar. Spar loads The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing D- ...
