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 ai ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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".

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.. During takeoff, ground effect 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 hovering can cause ...

2012 In Maryland
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural numbe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aircraft First Flown In 2012
An aircraft ( 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 the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." 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, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Breguet-Richet Gyroplane
The Breguet-Richet Gyroplane was an early French experimental quadcopter rotary-wing aircraft developed by Breguet Aviation. Design and development The Gyroplane No.I was one of the earliest attempts to create a practical rotary-wing aircraft. It was designed by the Bréguet brothers with help from Professor Charles Richet. The aircraft had an uncovered open steel framework with a seat for the pilot and a powerplant at the centre. Radiating from the central structure were four wire-braced tubular steel arms, each bearing a superimposed pair of four-bladed rotors. To eliminate the torque effect, two rotor sets were driven clockwise and two counter-clockwise. Operational service On 29 September 1907, the Gyroplane No.I was flown for the first time, albeit to an elevation of only .Young 1982, p. 28. It was not a free flight, as four men were used to steady the structure. It was neither controllable nor steerable, but it was the first time that a rotary-wing device had lifte ...

English Channel
The English Channel, also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest Sea lane, shipping area in the world. It is about long and varies in width from at its widest to at its narrowest in the Strait of Dover."English Channel". ''The Columbia Encyclopedia'', 2004. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some . The Channel aided the United Kingdom in becoming a naval superpower, serving as a natural defence against invasions, such as in the Napoleonic Wars and in the World War II, Second World War. The northern, English coast of the Channel is more populous than the southern, French coast. The major languages spoken in this region are English language, English and French language, French.

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 ...
