This day was the carnival of the crew. They finally saw the hope of the future, but this day was also the suffering day of the disciples, because the teacher issued new teaching materials and resumed classes.

    Not only did the schoolwork not decrease, but there was one more course, which was hopeless. No one in the five small children was interested in the soul guide. Even Dugu Bo didn''t like it. He was preparing a human body transformation project.

    It seems that I intend to conduct a human experiment in the new world. After all, the teacher will not let it harm my own people. It will be a big trouble to find volunteers at that time.

    Dugu Bo''s research project and the background of the film have been somewhat incomprehensible. He just prayed in his heart that he would not make a Douluo version of super soldier serum. At that time, Captain Douluo would be the first to kill him, the revolutionary leader who stirred the people''s movement.

    "You can''t be so spiritless! Soul guide is also a very important knowledge. How can you be an outstanding talent in the new era when you neglect it so much? " The undertaker pushed the toad mirror with decorative function, and lifted the trouser belt to the chest, which was dignified at once.

    "But we don''t really need to be able to make soul guides. Can we use them?" Meng Shu lay on the table like a salted fish, and the tail of the crane was talking about him.

    "And what the teacher said these days is so boring! Nothing interesting on board. " Posisi is also wilting. She yearns for freedom. She can''t accept squatting in the laboratory all day to make soul guides.

    The disciples were speechless. What did they say on the ship? Conic or analytic geometry? Maybe posisi will find it interesting.

    Looking at the disciples who haven''t watered for several days, the filmmaker reluctantly shook his head: "forget it, since you have so much resentment, I''ll take you to the quality development class in advance today! I tell you, after today''s class, there will be no more. The teacher is very tired of preparing a quality development class! "

    "Long live!"

    "I knew the teacher was the best!"

    "Finally I can go out and play!"

    Chengying looked at the appearance of several skin monkeys, feeling very much like himself when he was a child. At that time, the class heard that this was also the performance of outdoor classes.

    Chengying turns to leave and pulls the ice emperor out of bed. The confused ice emperor doesn''t get up because he doesn''t wake up at all. Chengying carries the back neck skin like a cat, and doesn''t know if the shoulder strap falls off.

    Of course, it doesn''t matter if you really fall down. There''s nothing anyway

    "What''s our course today?" Tang Chen took out six boxes of stored soul guides from the studio room. Each box was the same, and there were a large number of soul guides marked with serial numbers.

    "See the ingot over there? That''s the materials for today''s course experiment. Each of you should complete your own works by yourself. As for what the works are, here are the instructions. You''ll know by spelling them out according to the above. "

    With that, the undertaker handed a bundle of instructions with only one legend and one piece of paper to the five little ones, "you can help each other. Of course, you can do it by your own strength, but you will have a lot less time to play."

    Looking at the more than ten pages of instructions, several people had a big head. They knew what those storage soul guides were used for. They were allowed to punch parts by themselves.

    Looking at the bird like shape of the things on the drawing, they probably guessed the function of this thing. Nine times out of ten, they can take them to heaven.

    In fact, Chengying has long tried to use soul guidance technology to manufacture aircraft. The version given to the disciples is the version he has optimized and improved many times. The structure has been simplified to only more than 500 kinds of core parts. He also intends to see if his design can be understood by most people. If so, it can be mass produced.

    The reason why the aircraft can be designed so simply is still the storage soul guide. As an extremely precise equipment, the aircraft is an engine, which is not as simple as 500 parts.

    But he saved the engine... Because there is a storage soul guide! One is filled with high-pressure LNG, biogas, or hydrogen.

    The other is high-pressure liquefied oxygen, which is very easy to make. When the ice emperor drops the temperature casually, the air becomes a liquid cocktail. It is very simple to separate the oxygen.

    Igniting the gas mixture in a high-intensity combustion chamber can produce high-pressure airflow to drive the aircraft to fly. Although it is a waste, most of the energy has become internal energy, but it can''t stand it! In theory, this crap is actually a jet. It can go supersonic without fear of falling apart!

    It is impossible for a normal jet to carry so much fuel, otherwise it can''t fly. Therefore, a more efficient jet engine must be adopted. A storage soul guide can be used. Let alone ten tons of fuel, a hundred tons is just a matter of carrying more storage soul guides. Moreover, the storage soul guide can also set dolls indefinitely. If you don''t get lost, there is no pressure to fly around the world.

    When the disciples began to study the design drawings, Chengying started to assemble. First, the engine. More or less, he still adopted the principle of jet engine. After all, although oxygen is cheap, fuel is not possible. At the current mining level, a ton of liquefied natural gas can go on for more than a dozen gold coins. It''s nothing to play by yourself, But the air force can''t afford to be hurt.

    The structure of the engine is probably a five pointed star cylinder engine with insufficient combustion, which has not been seen in previous life. The recovered power is used to drive propeller aircraft, but the jet is far from enough.

    Therefore, there are two nozzles on both sides of the jet chamber. In fact, these two are the source of the main driving force. They are made of rare metals and can withstand the high temperature of 4000 degrees. There are two kinds of fully burning gases inside. When flying, the flame tail of more than ten meters will be pulled out from the back of the aircraft. It looks very cool, but it is actually a waste of energy.

    Then comes the fuselage, which is also the second important part of the aircraft. The aerodynamic effect of the aircraft is a very important parameter. In reality, it takes countless wind tunnel experiments to summarize the appropriate fuselage design.

    In this regard, the studio has drilled a loophole. He has seen so many planes in his previous life. With his current memory, he can recover the pictures in his mind, and there are ready-made models for the tempered aerodynamic shapes.

    Among many excellent aerodynamic shapes, the photographer picked up and finally chose the j-20. Not because of anything else, just because his name is j-20, the photographer will let him board an aircraft carrier in a different world!
