Buxton Hjordis
The Buxton Hjordis was a single-seat sailplane built by Slingsby Sailplanes Ltd. in the UK to a design by G.M Buxton. Only one was constructed and was flown by Philip Wills at competitions in Europe between 1935-7. Development The sole Buxton Hjordis was a high-performance sailplane designed by G.M "Mungo" Buxton and built in 1935 by Slingsby Sailplanes Ltd. It was a single-seater of all-wood construction. Its straight-tapered, cantilever wing was pedestal-mounted and was without flaps or airbrakes. The fuselage was circular in cross section with the cockpit immediately in front of the wing leading edge and a wheel-less, single-skid main undercarriage. Aft, the fuselage tapered to carry a very small triangular fin, on which was mounted a much taller, wide chord rudder of rounded triangular shape and with a vertical leading edge. The horizontal tail was small and essentially all elevator apart from a leading-edge hinge. Buxton began the design of a development, the Hjord ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

1930s British Sailplanes
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.

Sigurd
Sigurd ( non, Sigurðr ) or Siegfried (Middle High German: ''Sîvrit'') is a legendary hero of Germanic heroic legend, who killed a dragon and was later murdered. It is possible he was inspired by one or more figures from the Frankish Merovingian dynasty, with Sigebert I being the most popular contender. Older scholarship sometimes connected him with Arminius, victor of the Battle of the Teutoburg Forest. He may also have a purely mythological origin. Sigurd's story is first attested on a series of carvings, including runestones from Sweden and stone crosses from the British Isles, dating from the eleventh century. In both the Norse and continental Germanic tradition, Sigurd is portrayed as dying as the result of a quarrel between his wife ( Gudrun/Kriemhild) and another woman, Brunhild, whom he has tricked into marrying the Burgundian king Gunnar/Gunther. His slaying of a dragon and possession of the hoard of the Nibelungen is also common to both traditions. In other respect ...

Norse Mythology
Norse, Nordic, or Scandinavian mythology is the body of myths belonging to the North Germanic peoples, stemming from Old Norse religion and continuing after the Christianization of Scandinavia, and into the Nordic folklore of the modern period. The northernmost extension of Germanic mythology and stemming from Proto-Germanic folklore, Norse mythology consists of tales of various deities, beings, and heroes derived from numerous sources from both before and after the pagan period, including medieval manuscripts, archaeological representations, and folk tradition. The source texts mention numerous gods such as the thunder-god Thor, the raven-flanked god Odin, the goddess Freyja, and numerous other deities. Most of the surviving mythology centers on the plights of the gods and their interaction with several other beings, such as humanity and the jötnar, beings who may be friends, lovers, foes, or family members of the gods. The cosmos in Norse mythology consists of Nine Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wasserkuppe
The is a mountain within the German state of Hesse. It is a large plateau formation at an elevation of and is the highest peak in the Rhön Mountains. Great advances in sailplane development took place on the mountain during the interwar period, driven by annual contests. Near the summit there is still an airfield used by gliding clubs and pilots of light aircraft. Etymology The German name is derived from ''Wasenkuppe, Asenberg'' or ''Weideberg'' and means ''Pasture mountain''. Geography The Wasserkuppe lies in the administrative district Fulda north of Gersfeld. Other villages nearby are Poppenhausen ( west - south west) and Wüstensachsen ( east, part of Ehrenberg, Hesse). It is part of the Rhön Biosphere Reserve. The Wasserkuppe sources the spring of the river Fulda (the western source of the Weser) and the river Lütter which joins the Fulda after . The other peaks near the Wasserkuppe are Abtsrodaer Kuppe (north, NN), (east, NN) and Pferdskopf (so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sutton Bank
Sutton Bank is a hill in the Hambleton District of the North York Moors National Park, North Yorkshire in England. It is a high point on the Hambleton Hills with extensive views over the Vale of York and the Vale of Mowbray. At the foot of Sutton Bank lies the village of Sutton-under-Whitestonecliffe; at 27 letters long, it has the longest hyphenated placename in England. The A170 road runs down the bank with a maximum gradient of 1 in 4 (25%), and including a hairpin bend. Vehicles have to keep in low gear whilst travelling up or down the bank, and caravans are banned from using the section. History Just to the south of Sutton Bank is Roulston Scar, the site of one of the most important prehistoric monuments in the region—a massive hillfort built in the Iron Age, around 400 BC. It was the approximate location of the Battle of Old Byland in which the Scots won a major victory over the English on 14 October 1322. King Robert the Bruce had made a forced march with ...

Slingsby 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 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 with wooden structure covered by ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
