Human-powered Helicopter
A human-powered helicopter (HPH) is a helicopter powered solely by one or more humans carried on board. As in other human-powered aircraft, the power is usually generated by pedalling. It remains a considerable engineering challenge to obtain both the power-to-weight ratio and rotor efficiency required to sustain a helicopter in flight. On 13 June 2013, the AeroVelo Atlas was the first to complete a flight that lasted 64 seconds and reached an altitude of 3.3 meters or 10.82 feet, thus winning the American Helicopter Society (AHS) International's Igor I. Sikorsky Human Powered Helicopter Competition. The AHS Sikorsky Prize The American Helicopter Society (AHS) International's Igor I. Sikorsky Human Powered Helicopter Competition was a competition to achieve the first human-powered helicopter flight to reach an altitude of 3 m (10 ft) during a flight lasting at least 60 seconds, while remaining within a 10 m (32.8 ft) x 10 m (32.8 ft) square, ...

University Of Maryland Gamera II
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 ...

Helicopter History
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fédération Aéronautique Internationale
The World Air Sports Federation (; FAI) is the world governing body for air sports, and also stewards definitions regarding human spaceflight. It was founded on 14 October 1905, and is headquartered in Lausanne, Switzerland. It maintains world records for aeronautical activities, including ballooning, aeromodeling, and unmanned aerial vehicles (drones), as well as flights into space. History The FAI was founded at a conference held in Paris 12–14 October 1905, which was organized following a resolution passed by the Olympic Congress held in Brussels on 10 June 1905 calling for the creation of an Association "to regulate the sport of flying, ... the various aviation meetings and advance the science and sport of Aeronautics." The conference was attended by representatives from 8 countries: Belgium (, founded 1901), France ( Aéro-Club de France, 1898), Germany ( aka "German Airship League", founded 1902), Great Britain (Royal Aero Club, 1901), Italy (, 1904), Spain (, 19 ...

Soccer Centre
Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who almost exclusively use their feet to propel a ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is the world's most popular sport. Association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 and maintained by the IFAB since 1886. The game is played with a football that is in circumference. The two teams compete to score goals by getting the ball into the other team's goal (between the posts, under the bar, and fully across the go ...

Quadcopter
A quadcopter, also called quadrocopter, or quadrotor is a type of helicopter or multicopter that has four rotors. Although quadrotor helicopters and convertiplanes have long been flown experimentally, the configuration remained a curiosity until the arrival of the modern unmanned aerial vehicle or drone. The small size and low inertia of drones allows use of a particularly simple flight control system, which has greatly increased the practicality of the small quadrotor in this application. Design principles Each rotor produces both lift and torque about its center of rotation, as well as drag opposite to the vehicle's direction of flight. Quadcopters generally have two rotors spinning clockwise (CW) and two counterclockwise (CCW). Flight control is provided by independent variation of the speed and hence lift and torque of each rotor. Pitch and roll are controlled by varying the net centre of thrust, with yaw controlled by varying the net torque. Unlike conventional hel ...

University Of Maryland Gamera I
The University of Maryland Gamera I is a human-powered helicopter designed to win the $250,000 Sikorsky Prize. Development The Gamera I is purpose-designed quadrotor helicopter to meet the criteria of the 1980 Sikorsky Prize. Two other teams have made prize attempts unsuccessfully, The Da Vinci III, built by a team at the California Polytechnic State University in 1989 and the Yuri I. At the time the world record was of 19.46 seconds of flight at altitude made by the ''Yuri I'' helicopter developed by Nihon University. University of Maryland professor Fred Schmitz proposed an attempt at the prize for the engineering students, with Inderjit Chopra leading the effort. 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 aircraft must prove that it is controllable by remaining within a circle. Since the University of Maryland's mascot is a terrapin turtle, the craft is named Gamera, a no ...
