Zhang Yi continued: "Mr. Wilbur, now that we have succeeded in using propeller-powered aircraft, this will dominate the course of aviation for more than a century, but you must know that the propeller power model actually has limitations. [Ran^Text^Library] []. [774] [buy]. Fastest update visit: shuhahА. ”

Wilbur was stunned for a moment and asked, "Limitations?" Mr. President, what are the limitations of the propeller power mode? ”

Zhang Yi said: "Mr. Wilbur, once the aircraft comes out, it will cause a huge sensation in the world, and the world's major powers have set off a boom in the development of aircraft, which is predictable, and it is not impossible for the industrial base of the developed countries in the West to catch up with our level within 20 years, and if we want to maintain our leading position, then we must have other unique features." In terms of propeller power mode, when the speed and carrying capacity of our aircraft reach a certain level, the power that the propeller can provide to me is defective, because there is an upper limit to the rotation speed of the propeller, which is related to our materials, and our propeller blades cannot be infinitely enlarged. ”

After listening to Zhang Yi's words, Wilbur immediately fell into deep thought, and the people around Zhang Yi looked at Zhang Yi in amazement, this president even understands such a profound question! Don't you see, it's already stumped by Wilbur, a university scholar!

After a long time, Wilbur raised his head and said, "Mr. President, after my careful consideration, I think the problem you mentioned absolutely exists, and this barrier will definitely appear in the next twenty years, so since you have keenly discovered this problem, how can we solve it?" At least, our brother, in the foreseeable future, it is really difficult to think of a more suitable power mode, I'm sorry, I'm afraid I'm going to disappoint you......"

The people on the side felt even more incredible, the two scientists couldn't come up with a solution to this problem, even if it was theoretical!

Zhang Yi said with a smile: "Mr. Wilbur, in fact, it's not that there is no way to solve it, you and Mr. Orville can't imagine it, it's not that your theory is not good enough, but because you started with the propeller from the beginning, and after so many years of research, you have fallen into inertial thinking." ”

Wilbur was stunned for a moment and said, "Inertial thinking? ”

Zhang Yi affirmed: "Yes, it's inertial thinking!" In fact, the aircraft takes off one is the future, the propeller rotation brings the power of floating, relying on Mr. Newton's mechanical principles, also based on Newton's mechanical principles, we can also find another way, Newton's third mechanical principle is about reaction force, we can use reaction force, we can use reaction force, push our aircraft into the sky! ”

Wilbur frowned and asked, "Reaction force?" I don't know what kind of reaction force you want to rely on, Mr. President, to propel the plane forward and even take off? ”

Zhang Yi smiled: "The reaction force of the air! In our China, there is an item, we call it a flower, it is a kind of fireworks, with kraft paper as a shell, inside is filled with gunpowder, the outside is tied with a reed rod, when we light the gunpowder, because the gunpowder is burning, the temperature of the gas inside the flower rises suddenly, the gas will be instantly sprayed out from the bottom of the bottom, and then the air reacts to it, directly pushing it to the sky, this is the application of Newton's third law of mechanics, the same principle, we can apply it to the airplane, with the reaction force of the air to send the plane to the sky! ”

Wilbur's eyes lit up, and he said hurriedly: "Yes, Mr. President, your idea is too subtle, you are a genius, why didn't we think of such a way!" Firework! All fireworks fly into the sky with the help of reaction force, but they are with the help of the reaction force of the earth, and your flowering is with the help of the reaction force of the air, I, can I take a look at the flowering? ”

Zhang Yi commanded: "Ji Yubo! ”

Ji Yubo hurriedly walked up and said, "President! ”

"Immediately take someone out to find a few flowers and come back, so that Mr. Wilbur can see the flowers invented by our Chinese folk strangers, hahaha......"

Ji Yubo agreed, turned around and ran out.

Zhang Yi continued: "Mr. Wilbur, the working principle of Qihua is very simple, but his principle has something in common with the aircraft power model, but he can only give you a kind of inspiration, and the rest of the research and development will depend on you and your team to make unremitting efforts. ”

Wilbur laughed and said, "Mr. President, as long as we have a clear idea, the rest of the research is not a problem, if it is not successful in one year, then it will be two years, and if it is not successful in two years, then it will be three years, and one day, we will succeed in developing it!" ”

Zhang Yi said with a smile: "Okay, that's it, what I'm going to do now is to ask our test pilots to demonstrate the flight and combat of the plane for our generals here, Mr. Wilbur, please call two test pilots over, let's observe the plane in flight!" ”

Wilbur laughed and said: "No need for other pilots, this time our two brothers will personally go into battle to make a demonstration for you, you have a saying in China, that women are those who please themselves, and those who are confidants die!" Today, our brothers must let you see how useful the aircraft we have developed is! ”

Zhang Yi hurriedly stopped and said: "Mr. Wilbur, I resolutely do this to you, you are the key to the development of our aircraft, once the plane fails, you will face the danger of your life, we can't afford such a risk!" ”

Wilbur waved his hand and said: "Mr. President, you are too worried, we have personally piloted this plane no less than ten times, and the performance of the plane has stabilized, there will be no accidents, you can rest assured, at this time, I will not let our baby have any problems, this time we must fly it ourselves!" ”

Zhang Yi tried every means to stop the excited Wilbur, so he had to agree, and said solemnly: "Mr. Wilbur, I hope this is your last flight, because we can't let us such precious big scientists face such a major risk, in the future, all R&D personnel must not fly in aircraft, and now our aircraft R&D personnel are too few, we can't afford such a loss!" ”

Wilbur nodded movingly and said, "Mr. President, we promise you that this is our last flight, and after that, how about we never fly a plane again?" Zhang Yi nodded and said, "Okay, let's start now, Huai Jin, do you all have binoculars?" Everyone nodded, and Zhang Yi continued: "Let's go, let's wait for a high ground and observe the flight show of the plane nearby!" ”
