University Of Maryland Gamera II Human Powered Helicopter
The University of Maryland Gamera II is an improved human-powered helicopter designed to win the US$250,000 Sikorsky Prize. Development The Gamera II is a quadrotor helicopter purpose-designed to attempt an official flight duration record sanctioned by the National Aeronautic Association, and is a step in the progression of designs built to meet the criteria of the 1980 American Helicopter Society Igor I. Sikorsky Human Powered Helicopter Competition. It is the advanced follow-on model of the Gamera I developed the year prior. Two other teams have made Sikorsky Prize attempts unsuccessfully. On June 13, 2013, the University of Toronto Team's AeroVelo Atlas, managed to keep its helicopter in the air for 64.11 seconds, reach a peak altitude of 3.3 meters and drift no more than 9.8 meters from the starting point, claiming the prize. The requirements to win the Sikorsky Prize include achieving a flight duration of 60 seconds and reaching an "altitude" of . At the same time the ...

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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Ground Effect (aircraft)
For fixed-wing aircraft, ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a fixed surface.. Reduced drag when in ground effect during takeoff can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached.. For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At high weights this sometimes allows the rotorcraft to lift off while stationary in ground effect but does not allow it to transition to flight out of ground effect. Helicopter pilots are provided with performance charts which show the limitations for hovering their helicopter in ground effect (IGE) and out of ground effect (OGE). The charts show the added lift benefit produced by ground effect. For fan- and jet-powered vertical take-off and landing (VTOL) aircraft, ground effect when ...

Human-powered Aircraft
A human-powered aircraft (HPA) is an aircraft belonging to the class of vehicles known as human-powered transport. Human-powered aircraft have been successfully flown over considerable distances. However, they are still primarily constructed as engineering challenges rather than for any kind of recreational or utilitarian purpose. History Early attempts at human-powered flight were unsuccessful because of the difficulty of achieving the high power-to-weight ratio. Prototypes often used ornithopter principles which were not only too heavy to meet this requirement but aerodynamically unsatisfactory. First attempts In 1904, Scientific American published an article and a photograph of a bicycle plane built by Steward Winslow of Riparia, Washington. He attempted to fly his plane on 30 July 1904, but one of the wheels failed. An early human-powered aircraft was the Gerhardt Cycleplane, developed by W. Frederick Gerhardt at McCook Field in Dayton, Ohio in 1923. The aircraft h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft First Flown In 2012
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Gossamer Albatross
The ''Gossamer Albatross'' is a human-powered aircraft built by American aeronautical engineer Dr Paul B MacCready's company AeroVironment. On June 12, 1979, it completed a successful crossing of the English Channel to win the second Kremer prize worth £100,000 (). Design and development The aircraft was designed and built by a team led by Paul B. MacCready, a noted American aeronautics engineer, designer, and world soaring champion. ''Gossamer Albatross'' was his second human-powered aircraft, the first being the ''Gossamer Condor'', which had won the first Kremer prize on August 23, 1977, by completing a -long figure-eight course. The second Kremer challenge was then announced as a flight across the English Channel recalling Louis Blériot's crossing of 1909. The aircraft is of " canard" configuration, using a large horizontal stabilizer forward of the wing in a manner similar to the Wright brothers' successful ''Wright Flyer'' aircraft and powered using pedals to drive a ...

Kremer Prize
The Kremer prizes are a series of monetary awards, established in 1959 by the industrialist Henry Kremer. Royal Aeronautical Society Human Powered Flight Group The Royal Aeronautical Society's "Man Powered Aircraft Group" was formed in 1959 by the members of the Man Powered Group of the College of Aeronautics at Cranfield when they were invited to join the Society. Its title was changed from "Man" to "Human" in 1988 because of the many successful flights made by female pilots. Under the auspices of the Society, in 1959 the industrialist Henry Kremer offered the first Kremer prizes of £5,000 for the first human-powered aircraft to fly a figure-of-eight course round two markers half-a-mile apart. It was conditional that the designer, entrant pilot, place of construction and flight must all be British. In 1973 Kremer increased the prize to £50,000 and opened it to all nationalities, to stimulate interest. The first Kremer prize of £50,000 was won on 23 August 1977 by Dr. P ...

Gossamer Condor
The MacCready ''Gossamer Condor'' was the first human-powered aircraft capable of controlled and sustained flight; as such, it won the Kremer prize in 1977. Its design was led by Paul MacCready of AeroVironment, Inc. Design and development The Kremer Prize had been set up in 1959 by Henry Kremer, a British industrialist, and offered £50,000 in prize money to the first group that could fly a human-powered aircraft over a figure-eight course covering a total of one mile (1.6 kilometers). The course also included a ten-foot pole that the aircraft had to fly over at the start and at the end. Early attempts to build human-powered aircraft had focused on wooden designs, which proved too heavy. Very early attempts – notably the ' and ''Pedaliante'' – used catapult launches. In 1961, Southampton University's Man Powered Aircraft SUMPAC took to the air at Lasham Airfield on 9 November, piloted by Derek Piggott, achieving a maximum flight of 650 metres. One week later, on 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
