Foreign companies have invented a flying device that can take off by running, although everyone can fly now, but there are still a small number of people who want to try new tricks, otherwise no one will invent hot air balloons, helicopters, motor beds and cars in the black and white era to subvert our cognition. The pilot only needs to put half of his body in the aircraft and use his hands to carry the aircraft forward to help him run, and then he can take off.
Before talking about the principle, let's first talk about the history of the development of aircraft, at the beginning of the last century, the American Wright brothers successfully developed the Aviator One, he carried manned flight through his own power, the Wright brothers once said that he would succeed, a large part of the reason is because the British George Kelly wrote the dynamic aerodynamics, George Kelly is so obsessed with flying because he witnessed someone flying with a balloon when he was a child, this exciting scene made him plant the idea of soaring in the sky in his heart, he thought that the balloon was because it was lighter than the air, So it can fly, but why birds that are heavier than the air can easily soar in the sky, then how the bird takes off, all thanks to its wings, because when the bird spreads its wings and flies, it flaps the air through the tough flying feathers at the back edge of the wing area, creating a strong downward pressure resistance to help the birds provide strong flight power.
So the question is whether we can fly into the sky as long as we imitate the wings of birds, but things are not as simple as you think, the lift of the aircraft mainly comes from the air flow on the surface of the wings, but the artificial wings do not have a source of power, so it is impossible to take people off, some people may ask, if the artificial wings can not take people to the sky, but why the Swedish developed Archaeopteryx can take off just by pedaling the legs, this is mainly a reference to the gliding wings in birds, the typical representative is the seabird, the seabird when flying, There is no need to vibrate the wings, but with the help of the updraft in the air to ride it up, and finally fall into the water by gliding, which is why the Archaeopteryx flying device needs to run and take off from a high place, the entire fuselage of Archaeopteryx is made of excellent fiber carbon dimension, very strong and light, weighing only about 100 pounds, a pair of wings length of nearly 14 meters.
Unexpectedly, such a light flying device can accommodate a pilot who is twice as heavy as it is, and when flying, the foot can be placed in the cockpit, and the glider can be controlled through the foot pedals and hand rods in the cabin, and the flight speed can reach 130 kilometers per hour, and if it is impossible to land by leg strength, it can be landed by gliding on wheels.
Human ideas are always full of science fiction, and I don't know if you have any ideas that you want to ride.
