How are human flying machines as agile as birds?

It is that he will sometimes stop in the air and sometimes continue to soar, and no one will walk uncomfortably because there is a plane in the sky, so there will always be people who are not used to this mode of getting along with airplanes.

It's really good that human flying machines are like birds, and it's really good that people can fly freely in the sky like birds.

Human flying machines are made like bird wings, which can be waved to make the machine take off, and human hands have developed to get closer to the sky.

I think that many of the human aircraft are as flexible as birds, or even more flexible than birds, and some of their thinking and programming are beyond birds.

I don't think it's very likely, because birds are animals after all, and it's the nature of birds to fly, and machines can't be more flexible than real creatures.

According to the current development of science and technology, human aircraft will one day be as flexible as birds, and then they will be able to turn aircraft into driving tools.

I think that if human aircraft are as flexible as birds, they need to have a certain amount of technological development, and they also need to have a certain amount of technology.

I think that human aircraft are one of the more dangerous things, this kind of thing can interfere with the flight of airplanes, and it can also harm humans.

Being able to realize the staged dream of human beings to heaven is a thing that makes all mankind proud. This is exactly what only existed in ** many years ago.

Characteristics of birds adapted to flight life: Streamlined body shape, reduced in the air in flight.

resistance; The surface of the body is covered with feathers, and the forelimbs become wings; The pectoral muscles are well developed, and the wings are pulled to complete the flight action; The bones are hollow, filled with air, some are very thin, the sternum is prominent, and the pectoral muscles are developed; Large appetite and strong digestion; The rectum is short, and the stool is expelled at any time; The heart has a large percentage of body weight, a high number of beats, and a strong ability of the blood to deliver oxygen; Breathe with lungs, air sacs to assist breathing; Edentulism, weight loss; There is no bladder and no urine storage, so the bird's whole body is designed for flight.

Humans have been exploring flying like birds, and there is one type of flying machine, the ornithopter, which refers to a heavier-than-air aircraft whose wings flutter up and down like the wings of birds and insects. During the Spring and Autumn period in China, there were attempts to create flying wooden birds. Leonardo da Vinci of Italy sketched ornithopters in the 15th century.

In 1930, an Italian ornithopter model flew test. Since then, there have been a variety of ornithopter design schemes, but due to the problems of control technology, materials and structure, the ornithopter is still in the stage of model making and designation. As a result, people have not been able to fly like birds.

Why is that? Leonardo da Vinci once found from the dissection of birds that the arm muscles of birds are quite strong, while the arm muscles of humans are too "pale and weak".

Besides, even if a man can flick his wings as quickly as a bird, his blood ** is not enough. In other words, the human heart beats and metabolizes the bird. Statistics show that even if a person is equipped with a pair of wings weighing about 10 pounds, its function is less than 1 10 1 4 of a small pigeon.

It seems that people are really born unable to fly.

However, with the development of science and technology, especially the development of high-energy batteries and lightweight materials, perhaps one day people will install a very powerful and very light electric wing, so that people can fly into the sky. We hope that day will come sooner rather than later.

The Birdman Flying Machine is a powered aircraft that combines a human and a wing. The human body acts as the fuselage, a set of ultralight wings with several folds are tied to the back of the human body, and two miniature ducted fan engines are placed on both sides of the thighs, like a small person burrowing into the belly of a large dragonfly. During takeoff, the thrust generated by the engine slowly lifts the person off the ground and into the sky.

Despite its modest power, it can fly at a speed of 176 km/h and a maximum of 240 km. When landing, as long as you slow down, you can stand on the ground with both feet as firmly as a bird, and you can complete take-off and landing without a special airport and runway, as long as there is an open space. In addition, this aircraft is also equipped with modern devices such as autopilot and target exploration radar, and is equipped with multi-barreled machine guns on the wings, which can attack ground targets at any time, and can fly and fight, and move quickly.

The biggest advantage of this birdman aircraft is that it does not rely on any take-off and landing devices, does not have any special requirements for the take-off and landing environment, and is easy to learn and easy to carry the flight technology, which is especially suitable for equipping special forces, and can undertake tasks such as sneak attacks and rescue personnel.

Reduce accident rates. In the years since Chinese scientists couldn't explain exactly how space has changed seeds, a Beijing-based food conglomerate has been sending seeds and seedlings into space, and the company's space tomatoes have 27 percent more carotene than ordinary Xishi Biqi tomatoes, and cotton plants can reach up to six feet tall. Now, more and more Chinese companies are joining the research and development of space crops, with the ultimate goal of increasing crop yields and allowing limited land to feed more people.

Let the computer drive your car, which is now able to monitor all the equipment in the car using computer chips, and a new technology in the future will make the computer the driver of the car. These computer drivers are quick to react and take on the task of driving if the driver is in trouble. Like traditional cars, cars with computer-based drivers still have steering wheels, accelerator pedals, and brake pedals, but they are only connected to a computer chip.

Although some experts think that driving with a computer is asking for trouble, it does <>

I feel that since people have learned about aerodynamics and invented the aircraft, the aircraft are very fragile and inflexible, unlike other vehicles, like a car, even if it is more damaged, it can continue to drive, and it is very flexible to operate, but the aircraft is likely to be fatal even if it is slightly traumatized, and it can only fly at high speed, and its movements are limited. But the alien spacecraft in the movie is very damaged but can still fly on the ground, and most of the alien spacecraft can fly in the air like turning in circles on land, and they can fly in the air at various angles without high-speed driving, why don't people study the kind of aircraft that is flexible and has a relatively high injury tolerance? Seven years ago, Bryant's father, Robert, made a diamond from high-pressure gaseous carbon, which he then cleaned by placing it in an acidic solution.

Robert had hoped to return the next day with a yellow piece of industrial diamond, but to his surprise, he got a almost completely transparent, perfectly beautiful quarter carat carbon crystal, known as a diamond. Robert inadvertently fulfilled a dream that scientists had been unable to achieve for years: to create artificial diamonds that could be used in engagement rings. What do fruit flies know?

Michael Dickinson, a professor at the California Institute of Technology's Bureau of Bioengineering, has been studying fruit fly flight for years, using an ultra-high-speed camera to film the fly's wings to see how the creature turns in a fifth of a human blink. For this purpose, Dekkin Shomasen designed a large robotic fruit fly. After understanding the flight principle of fruit flies, he turned his research direction to the problem of how fruit flies know that they are going to **.

How did the fruit fly find a tiny wine glass in an empty classroom and land on the edge of the glass? <>
