At that time, people all over the world had experienced the tragic failures of various experiments over thousands of years, and they were already a little discouraged. Many people believe that it is impossible to achieve the purpose of flight simply by relying on the power of the instrument itself.
So when the Wright brothers¡¯ invention was announced, you can imagine the huge sensation they caused around the world.
Human beings have begun to spend their youth and blood on the dream of flying to the moon again, constantly making various improvements to the aircraft made by the Wright brothers, so that it can fly higher, further and for a longer time Son.
In 1910 AD, Henri Coanda, a young genius in France, designed a fifty-horsepower engine that pushed air backwards with the help of a fan. The engine also has an afterburner, which fully expands the gas in the micro-nozzle to increase reverse thrust.
Although this genius fell from the sky while performing an air show at a Paris exhibition, and was seriously injured. But people all over the world still remember the inventor of this jet aircraft.
With the needs of the war, governments of various countries vigorously supported aircraft research. With the unremitting efforts of scientists from all over the world, people finally solved the sound barrier problem of this jet propeller aircraft. When the aircraft started up with a thunderous sound, The moment the fuel ran out, the plane reached the speed of sound and reached an altitude of more than 4,000 feet in the sky.
The emergence of helicopters and passenger aircraft marks the maturity and stability of the aircraft manufacturing industry. It also marks that aircraft have become an indispensable means of transportation in human life, which has greatly changed and affected human living habits. .
And in the entire development process of the aircraft, the two most critical parts, the engine and the propeller, of course have different structures at different times.
From the piston engine at the beginning to the spiral shaft engine later, from the metal wood wing structure at the beginning to the metal structure and then to the fiberglass structure propeller, people gradually improved their model that can fly in the air. of transportation.
What Yinreng needs to do now in the fourth yard with toys is to develop the entire power propulsion device of the piston engine, the metal and wooden propellers, and a generally complete fuselage.
Just like a generator, it follows the steps of great people in history and makes experimental improvements bit by bit. Instead of manufacturing it according to the most advanced aircraft drawings of the twentieth century from the beginning.
Without a solid foundation, it cannot be built at all, or even if it is built reluctantly, it will be unstable. This is what Yinreng learned through the process of developing steam engines.
The main function of the aircraft engine, its ancillary equipment and fuel is to generate thrust or pull to propel the aircraft forward.
The propeller is a system closely related to the take-off and landing of the aircraft. The main function of this system is to support the entire aircraft when it is parked on the ground, taxiing, and taking off and landing. It can also absorb the impact energy when the aircraft lands and taxis, and steadily control the taxiing direction.
Of course, the aircraft's control system is equally important. Its main function is to form and transmit control instructions, that is, to control the rudder and other mechanisms of the aircraft to make the aircraft fly according to the predetermined route, etc. There are other communication systems, driver safety systems and other auxiliary equipment that are also necessary and cannot be omitted.
Little Miss Bear is like a fish in water in the yard of the toy store and gets along very well. Huang Luzhuang, who was delighted to see her talent, treated her as a direct disciple, leading the little girl to switch between academy knowledge and practical application as quickly as possible.
Of course, the little girl did live up to Huangluzhuang's painstaking cultivation. Here, her talents were fully displayed and used. In less than half a month, she was able to help these old craftsmen do a lot of data calculations. .
At this moment, there was no gloom and silence in the academy. The little girl who started to become cheerful and agile held the data she calculated and carried the entrustment of the apprentices. She looked at Yinreng who had just come in and had not started to do anything. She immediately felt numb. He quietly knocked on the door of Yinreng's office room.
"His Royal Highness, you told everyone a few days ago that the fuselage of the aircraft should adopt a hollow beam structure to ensure that the aircraft can have sufficient endurance and strength, which is similar to the roof of ordinary people's homes. "
"Regarding the angle of the beam structure, I made a simple calculation with others these days, and Mr. Huang sent it to you for review yesterday. This manuscript is the result of our calculation using another method last night. You I¡¯ll give it a look when I have time.¡±
Yinreng nodded, the apprentices have thisThere is the perfect material for what we envision. "
¡°About the materials for manufacturing aircraft, the production of parts, etc., we must study seriously with the masters. We must combine the actual situation and develop the aircraft as soon as possible.¡±
When the young people heard the instructions from His Highness the Crown Prince, their necks turned red all of a sudden, and they didn¡¯t know how to place their hands and feet.
It¡¯s simply too embarrassing, isn¡¯t it?
¡°Research that is unrealistic is just a fantasy. Fortunately, they were thinking happily just now that His Highness the Crown Prince approved of their idea.
The old craftsmen who have always been paying attention to the apprentice area, after asking about what happened here, just smiled and shook their heads kindly. As a young person, no one has ever made a mistake. This is normal. You can just change it in the future.
Huang Luzhuang said with a smile, "These children have been very excited these days, ready to fly to the sky and the moon at any time. Now they are brought back to the world by His Highness, which is great."
"One of the craftsmen, Wang, heard what Mr. Huang said, and his face was filled with sadness and sympathy. He had also made such a misplacement back then, and had an unforgettable experience of being gently pulled back to the human world by His Highness the Crown Prince.
Of course, everyone in the Toy Department has made such a mistake, except for their little prince.
In addition to their obsession with research, Mr. Huang, who is careless about other things, can ignore the small mistakes pointed out to him by His Royal Highness, and can persuade others with a light sentence every time. , just don¡¯t do it again in the future.
Craftsman Zhang, who looked kind and honest, said: "It's not surprising that these children are floating. It's just that we old people, who were chosen to come to this fourth yard and knew that we were going to develop a plane to fly to the moon, we all gave up." It took a lot of energy to calm down.¡±
¡°Who says it¡¯s not that? Flying to the sky and landing on the moon, what if my ancestors¡¯ dream for thousands of years could come true with my own hands. If I¡¯m not afraid of your jokes, I still feel a little bit like dreaming.¡±
"Isn't that just like a dream? It's more of a dream than a dream. I didn't dare to think about it when I dreamed before. When I went home a few days ago, my mother-in-law said that I felt like I was going crazy when I fell asleep, hehe."
More than a dozen old craftsmen were talking and talking, and found that everyone was the same. They were all full of disbelief. Some were still in a trance. Their usual research and experiments were supported by experience and instinct, and it was difficult for them to relax. burst into laughter.
Fortunately, they think that others are adapting well, so they hold it in hard and are embarrassed to be discovered by others.
"Mr. Huang, what about you? Are you fully accustomed to it now? Did His Highness the Crown Prince tell you about this in advance?"
"Yes, Mr. Huang, our two families are next to each other. I haven't heard my sister-in-law say anything wrong with you these days?"
