Endless Runway
An endless runway is an aircraft runway which loops around to form a shape such as a circle. There were experiments with this concept in the 1960s and it is now being researched at the Nederlands Lucht- en Ruimtevaartcentrumthe national aerospace laboratory of the Netherlands. History With the birth of aviation, the thought of taking a car to the office became old-style and soon people started to invent ways to take the airplane to the office. In an article in "Popular Science" from 1919, a circular runway was designed on top of some skyscrapers in New York, where one of the buildings would serve the purpose of aircraft parking. A design was made for a circular runway on the roof of Kings Cross railway station in London. In the 1960s, the idea was taken up by a marine officer, who actually performed a number of take-offs and landings with aircraft at a circular track designed for testing cars. This work stimulated a large number of patents with runways shaped as circles or o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooklands Banked Track - Geograph
Brooklands was a Auto racing, motor racing circuit and aerodrome built near Weybridge in Surrey, England, United Kingdom. It opened in 1907 and was the world's first purpose-built 'banked' motor racing circuit as well as one of Britain's first airfields, which also became Britain's largest aircraft manufacturing centre by 1918, producing military aircraft such as the Vickers Wellington, Wellington and civil airliners like the Vickers Viscount, Viscount and Vickers VC10, VC-10. The circuit hosted its last race in August 1939 and today part of it forms the Brooklands Museum, a major aviation and motoring museum, as well as a venue for vintage car, motorcycle and other transport-related events. History Brooklands motor circuit The Brooklands motor circuit was the brainchild of Hugh F. Locke King, Hugh Fortescue Locke King, and was the first purpose-built banked motor race circuit in the world. Following the Motor Car Act 1903, Britain was subject to a blanket speed limit on ...

Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Netherlands Aerospace Centre
The Royal Netherlands Aerospace Centre (Royal NLR; ), formerly known as the National Aerospace Laboratory (NLR; ) is an aerospace research organization of the Netherlands and is one of its major technological institutes. These institutes perform a large part of the applied research in the Netherlands, each within its own specific field of technology. As an independent non-profit organization, the NLR is the aerospace-knowledge enterprise in the Netherlands and provides technical support to the aerospace sector. Organization NLR performs research and develops technology in the field of aviation and space travel. Work under research contracts (national and international, government and industry) amounts to 75 percent of NLR's activities, the remaining 25 percent is funded by the Dutch government for basic demand-oriented research programs and development of research equipment. Depending on the project, NLR acts as a sole contractor or as a subcontractor cooperating with other instit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Insider
''Business Insider'' (stylized in all caps: BUSINESS INSIDER; known from 2021 to 2023 as INSIDER) is a New York City–based multinational financial and business news website founded in 2007. Since 2015, a majority stake in ''Business Insider''s parent company Insider Inc. has been owned by the international publishing house Axel Springer. It operates several international editions, including one in the United Kingdom. ''Insider'' publishes original reporting and aggregates material from other outlets. it maintained a liberal policy on the use of anonymous sources. It has also published native advertising and granted sponsors editorial control of its content. The outlet has been nominated for several awards, but has also been criticized for using factually incorrect clickbait headlines to attract viewership. In 2015, Axel Springer SE acquired 88 percent of the stake in Insider Inc. for $343 million (€306 million), implying a total valuation of $442 million. From ...

Rocket Sled Launch
A rocket sled launch, also known as ground-based launch assist, catapult launch assist, and sky-ramp launch, is a proposed method for launching space vehicles. With this concept the launch vehicle is supported by an eastward pointing rail or maglev track that goes up the side of a mountain while an externally applied force is used to accelerate the launch vehicle to a given velocity. Using an externally applied force for the initial acceleration reduces the propellant the launch vehicle needs to carry to reach orbit. This allows the launch vehicle to carry a larger payload and reduces the cost of getting to orbit. When the amount of velocity added to the launch vehicle by the ground accelerator becomes great enough, single-stage-to-orbit flight with a reusable launch vehicle becomes possible. For hypersonic research in general, tracks at Holloman Air Force Base have tested, as of 2011, small rocket sleds moving at up to (; Mach 8.5). Effectively a ''sky ramp'' would make th ...

Ski-jump (aviation)
In aviation, a ski-jump is an upwardly curved ramp that allows a fixed-wing aircraft to take off from a runway that is shorter than the aircraft normally requires. By providing an upward vector from the ski-jump's normal force, the aircraft is launched at an elevated angle and lift-off can be achieved at a lower airspeed than that required for flat takeoff, as it allows the aircraft more time to continue accelerating while airborne after leaving the runway. Ski-jumps are commonly used to launch shipborne aircraft from aircraft carriers that lack catapults. It is believed that the first use of the ski-jump occurred during the Second World War, when a temporary ramp was added to to help heavily laden Fairey Barracudas attack the German battleship . During the Cold War, the concept was studied as a means of reducing the length of flight decks required for aircraft carriers and to facilitate ever-heavier aircraft at sea. The Royal Navy took a particular interest in the ski-jump d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
