Dunstable Kestrel
The Manuel Crested and Willow Wrens formed a series of wooden, single-seat gliders designed in the UK by W. L. Manuel in the early 1930s, intended for slope soaring. Some were built by the designer, others from plans he supplied. The Dunstable Kestrel was a further development. Design and development The Crested Wren was the first of the series, its design influenced by contemporary German practice. It was built by Manuel. Its two-piece wings had single spars which, together with plywood wing coverings forward of them, formed D-shaped box girders. The wooden ribs were produced in batches with a method devised by Manuel. Behind the spar the wings were fabric covered. The wings, which were slightly swept about the spars, had a constant-chord centre section, tapering outboard with ailerons and rounded tips. There were no flaps or airbrakes. The wings were mounted on a fuselage pylon and had lift struts from the lower fuselage. Two flying wires from the nose a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Wikimedia project, 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.

Ash (Fraxinus)
''Fraxinus'' (), commonly called ash, is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of subtropical species are evergreen. The genus is widespread across much of Europe, Asia, and North America. The leaves are opposite (rarely in whorls of three), and mostly pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara. Some ''Fraxinus'' species are dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness ; if grown as an ornamental and both sexes are present, ashes can cause a considerable litter problem with their seeds. Rowans or mountain ashes hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliding Heritage Centre
The Gliding Heritage Centre (GHC) is a collection of vintage gliders based at Lasham Airfield, Hampshire, UK. Origins Christopher Wills, the son of Philip Wills, founded the Vintage Glider Club in 1973. He died on 4 May 2011 but left a bequest of £100,000 to build a hangar to house vintage gliders plus his Steinadler. A group of enthusiasts decided to create a Gliding Heritage Centre which could be visited by members of the public in a building called The Chris Wills Memorial Hangar. It is a registered charity No 1148972. After raising more money and with much volunteer work, the first hangar was opened on the 4th August 2013 during the 41st International Vintage Glider Club rally that was held at Lasham that year. Further fund raising allowed the building of a second hangar to house the ever increasing collection of gliders. Hangar 2 was officially opened on 25 August 2018. A dedicated workshop is almost complete following a further bequest from Trish Williams. This will a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surrey
Surrey () is a ceremonial and non-metropolitan county in South East England, bordering Greater London to the south west. Surrey has a large rural area, and several significant urban areas which form part of the Greater London Built-up Area. With a population of approximately 1.2 million people, Surrey is the 12th-most populous county in England. The most populated town in Surrey is Woking, followed by Guildford. The county is divided into eleven districts with borough status. Between 1893 and 2020, Surrey County Council was headquartered at County Hall, Kingston-upon-Thames (now part of Greater London) but is now based at Woodhatch Place, Reigate. In the 20th century several alterations were made to Surrey's borders, with territory ceded to Greater London upon its creation and some gained from the abolition of Middlesex. Surrey is bordered by Greater London to the north east, Kent to the east, Berkshire to the north west, West Sussex to the south, East Suss ...

Brooklands Museum
Brooklands Museum is a motoring and aviation museum occupying part of the former Brooklands motor-racing track in Weybridge, Surrey, England. Formally opened in 1991, the museum is operated by the independent Brooklands Museum Trust Ltd, a private limited company (No.02109945) and a registered UK charity (No.296661); its aim is to conserve, protect and interpret the unique heritage of the Brooklands site. History of Brooklands Brooklands was the birthplace of British motorsport and aviation and the site of many engineering and technological achievements throughout eight decades of the 20th century. The racing circuit was constructed by local landowner Hugh F. Locke King in 1907 and was the first purpose-built racing circuit in the world. Many records were set there. Many aviation firsts are also associated with Brooklands, which soon became one of Britain's first aerodromes. It attracted many aviation pioneers prior to World War I, and was also a leading aircraft design and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Dunstable Sailplane Company
The Dunstable Sailplane Company was established in 1934 by W.L. Manuel and C.H. Latimer-Needham to design, manufacture and repair gliders from its workshop at Barton-Le-Clay Airfield in Bedfordshire. The Dunstable Kestrel was manufactured by the company from designs by W.L. Manuel in 1935; production was limited to one sailplane with a British Gliding Association id of G221. Records comment that G221 was purchased by a trainee pilot who was still in his early stages of training with a primary glider. This Dunstable Kestrel passed to the Norfolk & Norwich Aero Club and crashed in 1938, however W.L. Manuel drew up plans for home builders which were offered for sale at the cost of £6. 6s. W.E. Godson purchased a set of plans and built a second British Kestrel whilst three more Kestrels were built in Australia by R. New, R. Basillie and the last by P. Pratt. Whilst no remains exist of the British built aircraft all three Australian-built ones are in museums. W. L. Manuel was b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Washout (aviation)
Washout is a characteristic of aircraft wing design which deliberately reduces the lift distribution across the span of an aircraft’s wing. The wing is designed so that the angle of incidence is greater at the wing roots and decreases across the span, becoming lowest at the wing tip. This is usually to ensure that at stall speed the wing root stalls before the wing tips, providing the aircraft with continued aileron control and some resistance to spinning. Washout may also be used to modify the spanwise lift distribution to reduce lift-induced drag. Design considerations Washout is commonly achieved by designing the wing with a slight twist, reducing the angle of incidence from root to tip, and therefore causing a lower angle of attack at the tips than at the roots. This feature is sometimes referred to as structural washout, to distinguish it from aerodynamic washout. Wingtip stall is unlikely to occur symmetrically, especially if the aircraft is maneuvering. As a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihedral (aircraft)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Downs
The South Downs are a range of chalk hills that extends for about across the south-eastern coastal counties of England from the Itchen valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate, East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs and includes large parts of the Weald. The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England. The South Downs are relatively less populated compared to South East England as a whole, although there has been large-scale urban encroachment onto the chalk downland by major seaside resorts, including most no ...
