» Czech F-bike bicycle fly overhead in the air Cenci get points
When we are eagerly looking forward to flying cars one day from paper ideas into actual vehicles, officially took off in front of the world, flying bicycle research and development, but in no assertive attitude, really flew into our lives. While it is still unable to afford a real adult weight, and can only stay in the air for 5 minutes, but perhaps sufficient for movie "ET The Extra" in the little boy with a bicycle carrying his beloved ET fly overhead. Flying bike this research by the Czech researchers, was named "F-bike", 6 月 12, At Prague held a public flight. Car weight 95 kg, before and after the two, so each one with battery-powered propeller, now temporarily Remote control, car and replace real dummy. It slowly rose to 2,3 meters and flying time of about 5 minutes. F-bike principles of flight and battery life F-bike helicopter flight principle and similar, is simply the air down "throw", that is, above the spiral blade bicycle absorb the stability in the air and then pull it down, and when the bicycle is applied to the pressure in the air, the air also applied to the thrust on the bike, which is the reaction. When the air is applied to the body of the bike and the bike on the thrust equal gravity, bicycles can be hovering in the air. To make the F-bike fly longer and farther, it has a great relationship with the battery. First F-bike must use high-energy density batteries, if using generally large, old lead-acid batteries, can cause serious weight problems. And the battery capacity is able to continue to improve is the future commercialization of key factors, the current battery capacity is doubled every ten years, will improve cell efficiency, perhaps the future bicycle when this becomes more powerful, we can use it on movement and travel in flying. English Flyke Flying Tricycle F-bike flying bike is not the first, back in 2009, from Oxford University Carver (John Carver) had been built out of a station named Flyke of flying tricycle, and raise money for charity over the UK to complete the feat. This Flyke powered by a two-stroke dual-propeller motor, the car set paraglider canopy, and is equipped with a parachute, when Flyke flying in the sky, the parachute opens. Must add oil once every two hours, and can carry 25.4 kg less baggage, flight speed can reach 32 kilometers per hour. Currently this car has been sold, interested readers may, Mr. Crawford on site queries.News source:
