Blackburn Type E
The Blackburn Type E was a development of the earlier Blackburn Mercury single-engined monoplanes, but was innovative in its use of steel tubing to construct the fuselage. It was built during 1912 to compete in the Military Aeroplane Trials. A single-seat version flew, but the military two-seater did not. Design and development The Type E was a natural development of the line that led from the Blackburn Second Monoplane through the Mercury series. The main difference was in the construction of the fuselage, designed for military and overseas use and built with an aluminium-covered steel frame. It was the first British aircraft to have an all-metal fuselage, and with steel used in both wings and tail structures it was referred to as an all-steel aircraft. The wings of the Type E, like those of the earlier Mercurys, were thin in cross-section and rectangular in plan. The span was the same as that of the Mercury I, but they used the construction methods of the Mercury III, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flying Wires
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more im ...

1910s British Military Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 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. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V. China * A coalition of Chinese warlords from the east of Hangu Pass launches a punitive campaign against the warlord Dong Zhuo, who seized control of the central government in 189, and held the figurehead Emperor Xian hostage. After suffering some defeats against the coalition forces, Dong Zhuo forcefully relocates the imperial capital from Luoyang to Chang'an.

Larkhill
Larkhill is a garrison town in the civil parish of Durrington, Wiltshire, England. It lies about west of the centre of Durrington village and north of the prehistoric monument of Stonehenge. It is about north of Salisbury. The settlement has a long association with the British military and originally grew from military camps. It is now one of the main garrisons on Salisbury Plain, along with Tidworth Camp, Bulford Camp, and Waterloo Lines at Warminster. The Royal School of Artillery is at Larkhill and the Royal Artillery moved its main barracks there from Woolwich in 2008. Etymology Before the military garrison was established the area was known as Lark Hill, part of Durrington Down, owing to it being the highest point in the parish. After the first military buildings were established, it came to be known as Larkhill Camp. History Much of Larkhill lies within the Stonehenge World Heritage Site, an area rich in Neolithic and Bronze Age monuments. Several long barrows a ...

Aerial Derby
The Aerial Derby was an air race in the United Kingdom sponsored by the '' Daily Mail'' in which the competitors flew a circuit around London. It was first held in 1912, with subsequent races in 1913 and 1914. Suspended during the First World War, the event was revived in 1919 with a "Victory Aerial Derby". Further races were held in 1920, 1921,1922 and 1923. Although a race was scheduled for 1924 there were insufficient entries, and the event was cancelled and not held again. 1912 The first race, held on Saturday 8 June consisted of a single circuit of an course, starting and finishing at Hendon Aerodrome with control points at Kempton Park, Esher, Purley and Purfleet. At these contestants had to fly low enough for the judges to see the race number of their aircraft. The first prize was £250 and a gold cup. The first competition was the subject of enormous public interest, with around 45,000 people paying to view the start and finish at Hendon and enormous crowds gather ...

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 ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Kingpost
A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below). In aircraft design a strut called a king post acts in compression, similarly to an architectural crown post. Usage in mechanical plant and marine engineering differs again, as noted below. Architecture A king post extends vertically from a crossbeam (the tie beam) to the apex of a triangular truss. The king post, itself in tension, connects the apex of the truss with its base, holding up the tie beam (also in tension) at the base of the truss. The post can be replaced with an iron rod called a king rod (or king bolt) and thus a king rod truss. The king post truss is also called a "Latin truss". In traditional timber framing, a crown post looks similar to a king post, but it is very different structurally: whereas th ...

Wing Warping
Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft. The technique, used and patented by the Wright brothers, consisted of a system of pulleys and cables to twist the trailing edges of the wings in opposite directions. In many respects, this approach is similar to that used to trim the performance of a paper airplane by curling the paper at the back of its wings. Description In 1900, Wilbur Wright wrote, "...my observations of the flight of birds convince me that birds use more positive and energetic methods of regaining equilibrium than that of shifting the center of gravity...they regain their lateral balance...by a torsion of the tips of the wings. If the rear edge of the right wing tip is twisted upward and the left downward the bird becomes an animated windmill and instantly begins to turn, a line from its head to its tail being the axis." After Wilbur demonstrated the method, Orville noted, "From this it was apparent that the wings of a mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blackburn Second Monoplane
The Blackburn Second Monoplane was strongly influenced by the French ''Antoinette'' and was much more successful than Robert Blackburn's first aircraft. The lone aircraft was built in Leeds, UK in 1910. Development The First Monoplane was not a success, barely leaving the ground before crashing. His second machine, the Second Monoplane was very different, and resembled Léon Levavasseur's Antoinette design which Blackburn had seen in France. The monoplane wing was rectangular with a constant chord, significant dihedral and square tips, and had a thin aerofoil section cambered on the underside, as was usual at the time. Lateral control was by wing warping. The wing was wire braced via a kingpost passing through the fuselage, extending both above and below. The fuselage was, like the wings, a wooden structure covered with fabric, triangular in section and tapering towards the tail. This was characteristically ''Antoinette'' with a long, finely tapering fin and tailplane, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1912 British Military Aeroplane Competition
In 1911 the British War Office announced their first Military Aeroplane Competition for aircraft to meet the requirements of the Air Battalion Royal Engineers. The formal requirements were published in December 1911. By the time the trials were held in August 1912, the Air Battalion had become the Military wing of the Royal Flying Corps (RFC). It was held at Larkhill on Salisbury Plain, and the competition was won by S. F. Cody with his Cody V biplane. "Specification for a Military Aeroplane" By 1911 it was clear that the development of aircraft had reached the point where they were of military significance. France, the world leader in aviation at the time, had over 200 aircraft in military service. In contrast, Britain's total military aircraft strength was nineteen aircraft, of which, in the words of Colonel J.E.B Seely, Under-Secretary of State for War, "one is broken beyond repair and one is quite out of date. Others are more or less under repair" adding "We are arriving a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
