Droop Nose (aeronautics)
The droop nose or drooped nose is a feature fitted to a small number of aircraft designs, the majority of these being also equipped with delta wings and capable of supersonic speeds. It is typically fitted upon an aircraft that possesses a sharp nose-up attitude during the takeoff and landing phases of flight, which would result in a conventional nose cone obscuring the flight crew's view of the runway and ground alike. On an aircraft fitted with a droop nose, the pilot is able to lower the nose cone, thereby improving visibility. Throughout the majority of a flight, the nose would be kept in the raised position for greater aerodynamic efficiency. Droop noses have typically been installed on supersonic airliners, such as Concorde and the Tupolev Tu-144, and high-speed experimental aircraft, such as the record-breaking Fairey Delta 2 and the Sukhoi T-4 strategic bomber. History The first supersonic delta to receive a drooped nose was the Fairey Delta 2, a British ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into multiple classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibians; then within these classes, there are records for aircraft in a number of weight categories. There are still further subdivisions for piston-engined, turbojet, turboprop, and rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline indicates unofficial records, including unconfirmed or unpublicized war secrets. Official records versus unofficial The Lockheed SR-71 Blackbird holds the official Air Speed Record for a manned airbreathing jet engine aircraft with a speed of . The reco ...

North American XB-70 Valkyrie
The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 nuclear-armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command. Designed in the late 1950s by North American Aviation (NAA), the six-engined Valkyrie was capable of cruising for thousands of miles at Mach 3+ while flying at . At these speeds, it was expected that the B-70 would be practically immune to interceptor aircraft, the only effective weapon against bomber aircraft at the time. The bomber would spend only a brief time over a particular radar station, flying out of its range before the controllers could position their fighters in a suitable location for an interception. Its high speed made the aircraft difficult to see on radar displays and its high-altitude and high-speed capabilities could not be matched by any contemporaneous Soviet interceptor or fighter aircraft. The introduction of the first Soviet surface-to-air missiles i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canard (aeronautics)
In aeronautics, a canard is a wing configuration in which a small forewing or foreplane is placed forward of the main wing of a fixed-wing aircraft or a weapon. The term "canard" may be used to describe the aircraft itself, the wing configuration, or the foreplane.. Canard wings are also extensively used in guided missiles and smart bombs. The term "canard" arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck (''canard'' in French) with its neck stretched out in flight. Despite the use of a canard surface on the first powered aeroplane, the Wright Flyer of 1903, canard designs were not built in quantity until the appearance of the Saab Viggen jet fighter in 1967. The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Aerodynamic Drag
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Streamlined
Streamlines, streaklines and pathlines are field lines in a fluid flow. They differ only when the flow changes with time, that is, when the flow is not steady. Considering a velocity vector field in three-dimensional space in the framework of continuum mechanics, we have that: * Streamlines are a family of curves whose tangent vectors constitute the velocity vector field of the flow. These show the direction in which a massless fluid element will travel at any point in time. * Streaklines are the loci of points of all the fluid particles that have passed continuously through a particular spatial point in the past. Dye steadily injected into the fluid at a fixed point extends along a streakline. * Pathlines are the trajectories that individual fluid particles follow. These can be thought of as "recording" the path of a fluid element in the flow over a certain period. The direction the path takes will be determined by the streamlines of the fluid at each moment in time. * Ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triplex Safety Glass
Triplex Safety Glass was a British brand of toughened glass and laminated glass. The marque is often seen on vehicle and aircraft windscreens. History The Triplex Safety Glass Company Ltd was founded in 1912 by Kent-born Reginald Delpech (30 March 1881 - 29 May 1935). The company was established in 1912 to build laminated windscreens in Britain, under French patents. On 9 September 1929 Triplex formed a joint venture company with Pilkington in St Helens. The company is now part of Pilkington Automotive. In the 1960s Triplex bought its main competitor British Indestructo Glass, giving it a monopoly in British laminated glass production. In the 1980s, around 1,000 people worked at the Triplex site in St Helens and about 700 at the site in Kings Norton. Pilkington retired the Triplex brand in August 1993. The company was formally dissolved in September 2019. Key people * Sir Graham Cunningham, Chairman * Alan Brooke, 1st Viscount Alanbrooke, Chairman, 1954–1956 * Derek Co ...

Ogee
An ogee ( ) is the name given to objects, elements, and curves—often seen in architecture and building trades—that have been variously described as serpentine-, extended S-, or sigmoid-shaped. Ogees consist of a "double curve", the combination of two semicircular curves or arcs that, as a result of a point of inflection from concave to convex or ''vice versa'', have ends of the overall curve that point in opposite directions (and have tangents that are approximately parallel). First seen in textiles in the 12th century, the use of ogee elements—in particular, in the design of arches—has been said to characterise various Gothic and Gothic Revival architectural styles. The shape has many such uses in architecture from those periods to the present day, including in the ogee arch in these architectural styles, where two ogees oriented as mirror images compose the sides of the arch, and in decorative molding designs, where single ogees are common profiles (see opening image) ...
