Sir, talented person, why don't you try making a flapping-wing plane yourself? Maybe you can apply for a patent and get rich. Go to the peak of life. Okay, this is bullshit. Planes can fly because there are jets. Gave a forward force. The plane itself is very light. The same size, the plane is only a fraction of the soil. Big data error. In other words, the plane is light and powerful, so it flies. I'm kidding, because look at that frog, you know, it can jump, so the take-off of our plane is a simulation of the take-off process of a jet plane. Frogs are catapults. Give yourself an upward force with your feet. An airplane is a jet and an upward force. After taking off, how to ensure that it will not fall off is a mathematical problem, which is very complicated. Anyway, have you ever seen a paper plane fall with the wind? The same is true of airplanes. Although its wings can't be stirred, the pressure is different from top to bottom. This is physical knowledge. The pressure under the plane is high, but it is actually air pressure. The pressure above is small, which is also atmospheric pressure. The difference between the two pressures will increase with the increase of speed. So in the end, relying on the pressure difference, the plane can float in the air, just like a fish. Then there is the problem of flapping wings. Yeah, ha ha ha. In theory, birds can fly very high, and also use this pressure difference to have an updraft. I wish I could fly into the sky and wait for death. You will be exhausted. However, our micro air vehicle was really shaken by high speed. It's 1000 times per minute, and it's flying at low altitude, probably below 10 meter, which is a big mistake. Hummingbirds can't fly high, which is probably why. It takes too much physical strength to incite wings, and it is extremely demanding for wings. The plane can't meet this requirement for the time being, and it's unnecessary. Like whales, they don't move forward vigorously by wagging their tails at high speed.
In history, many planes have big brain holes, many of which are inflammatory, but they are not as good as our fans. So in the end, inflammatory type was eliminated. All wet.
