Penrose Pegasus
The Penrose Pegasus was a 1930s high-wing, single-seat, wooden glider from the UK. Designed, built and flown by Harald Penrose until the start of World War II, only one was built at the time though a reproduction was constructed in the 1990s. Design and development In 1932 Penrose, Chief Test Pilot at Westland Aircraft from 1931–53, began the design of a wooden single-seat glider. One unusual design constraint was that no component could be more the 12 ft 6 in (3.81 m) long in order for it to leave the workshop. The wing of the Pegasus had the same spar and planform as the unbuilt Cloudcraft Junior. It was constructed around a single box spar of spruce and plywood and had three sections, a parallel- chord centre section and two slightly longer, tapered outer panels with ailerons along the whole of their trailing edges. It was fabric covered and braced with lift struts to the lower fuselage longerons. Both rudder and elevator were all-moving surfac ...

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 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. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Longerons
In engineering, a longeron and stringer is the load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis. Longerons are used in conjunction with stringers to form structural frameworks. Aircraft In aircraft fuselage, stringers are attached to formers (also called frames) and run in the longitudinal direction of the aircraft. They are primarily responsible for transferring the aerodynamic loads acting on the skin onto the frames and formers. In the wings or horizontal stabilizer, longerons run spanwise (from wing root to wing tip) and attach between the ribs. The primary function here also is to transfer the bending loads acting on the wings onto the ribs and spar. Sometimes the terms "longeron" and "stringer" are used interchangeably. Historically, though, there is a subtle difference between the two terms. If the longitudinal members in a fuselage are few in number (usually 4 to 8) and run all along the ...

Kimmeridge
Kimmeridge () is a small village and civil parish on the Isle of Purbeck, a peninsula on the English Channel coast in Dorset, England. It is situated about south of Wareham and west of Swanage. In 2013 the estimated population of the civil parish was 90. Kimmeridge is a coastal parish and its coastline forms part of the Jurassic Coast, a World Heritage Site. The coast is also part of a Site of Special Scientific Interest, and the whole parish is part of the Dorset Area of Outstanding Natural Beauty. Kimmeridge is the type locality for Kimmeridge Clay, the geological formation that covers most of the parish. Within the clay are bands of bituminous shale, which in the history of the village have been the focus of several attempts to create an industrial centre. An oil well has operated on the shore of Kimmeridge Bay since 1959. The village is the origin of the name of the Kimmeridgian stage of the Late Jurassic. The roughly semi-circular Kimmeridge Bay is southwest of Kimme ... [...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 ...

Dorset
Dorset ( ; archaically: Dorsetshire , ) is a county in South West England on the English Channel coast. The ceremonial county comprises the unitary authority areas of Bournemouth, Christchurch and Poole and Dorset (unitary authority), Dorset. Covering an area of , Dorset borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The county town is Dorchester, Dorset, Dorchester, in the south. After the Local Government Act 1972, reorganisation of local government in 1974, the county border was extended eastward to incorporate the Hampshire towns of Bournemouth and Christchurch. Around half of the population lives in the South East Dorset conurbation, while the rest of the county is largely rural with a low population density. The county has a long history of human settlement stretching back to the Neolithic era. The Roman conquest of Britain, Romans conquered Dorset's indigenous Durotriges, Celtic tribe, and during the Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maiden Newton
Maiden Newton is a village and civil parish in the county of Dorset in south-west England. It lies within the Dorset Council administrative area, about north-west of the county town, Dorchester. Geography The village is sited on Upper Greensand at the confluence of the River Frome with its tributary of equivalent size, the Hooke. Both these rivers have cut valleys into the surrounding chalk hills of the Dorset Downs. The A356 main road passes through the village.

British Gliding Association
The British Gliding Association (BGA) is the governing body for gliding in the United Kingdom. Gliding in the United Kingdom operates through 80 gliding clubs (both civilian and service) which have 2,310 gliders and 9,462 full flying members (including service personnel), though a further 17,000 people have gliding air-experience flights each year. History A gliding event first occurred in the UK on a hill at Itford in East Sussex in 1922. The meeting was largely a publicity stunt by the ''Daily Mail'' newspaper which had offered a prize of one thousand pounds for the longest flight. However little gliding happened in the UK for several years after until reports of long flights in thunderstorms in Germany appeared in ''The Aeroplane'' magazine. Douglas Culver suggested a lunch meeting at the Comedy Restaurant in London on 4 December 1929 for anybody who was interested. Fifty-six people attended and a committee was formed. Shortly after the BGA was founded to start the spor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leading Edge
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. Characteristics Sweep Seen in plan the leading edge may be straight, curved, kinked or a combination of these. A straight leading edge may be swept or unswept, while curves or kinks always mean that part of the leading edge is swept. On a swept wing the sweep angle may differ from that of the wing, as wing sweep is conventionally measured at the airfoil 25% chord line. However on a delta wing the leading edge sweep defines the wing sweep. Radius and stagnation point A rounded leading edge helps to maintain a smooth airflow at varying angles of incidence to the airflow. Most subsonic airfoils therefore have a rounded leading edge. The degree of rounding is characterised by the profile radius at that point. The airflow divides to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stabilator
A stabilator is a fully movable aircraft horizontal stabilizer. It serves the usual functions of longitudinal stability, control and stick force requirements otherwise performed by the separate parts of a conventional horizontal stabilizer and elevator. Apart from reduced drag, particularly at high Mach numbers, it is a useful device for changing the aircraft balance within wide limits, and for reducing stick forces. Stabilator is a portmanteau of ''stabilizer'' and ''elevator''. It is also known as an all-moving tailplane, all-movable tail(plane), all-moving stabilizer, all-flying tail(plane), all-flying horizontal tail, full-flying stabilizer, and slab tailplane. General aviation Because it involves a moving balanced surface, a stabilator can allow the pilot to generate a given pitching moment with a lower control force. Due to the high forces involved in tail balancing loads, stabilators are designed to pivot about their aerodynamic center (near the tail's mean quarter-chord ...

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 ...
