According to foreign media reports, the United States 50 engineers at the University of Maryland after two years of arduous research, creating a human-driven helicopter, drivers push the pedals you can power the aircraft, will today (12th) test into the sky. History of human flight, has not yet successfully tested human helicopter, 1994 a Japan Human helicopter engineer flight test, but only about 0.2 m from the ground where flew for 19.46 seconds.
12th, if this human helicopters could fly over to 3 m high, and stays in the air more than a minute, then the University of Maryland’s engineers will be able to win the Sikorsky prize of US $ 250,000 (Sikorsky Prize).
Sikorsky prize is a United States helicopter society (American Helicopter Society) which was established in 1980 to encourage engineers research produced the first human-driven helicopter.
Human helicopter does not like ordinary aircraft with fixed wings. Only by constantly push pedal, pilots to achieve enough thrust fly on the sky.
United Kingdom Manchester University Antonio feilipuli (Antonio Filipponee) said: “If there is a fixed wing, only needs to provide forward thrust of aircraft to aircraft can be launched, because the fixed-wing itself upward lift will be provided. But the helicopter does not have a fixed wing, so at least 15 times times greater than normal aircraft power to take off, this is a great challenge. ”
Engineers at the University of Maryland to produce this human helicopter also has a name called “beauty”. “Beauty” fuselage 18.29 metres long, each rotor is 12.8 meters in diameter, placed on the ground about a standard football field area, one-third, but only 63.5 kg in weight.
12th, 24 year old biology student Judy-weikesile (Judy Wexler) will drive the aircraft into the sky. She has been selected, is because the weight is light, but it is also a cyclist, physically very strong.
