"How do you know?" Zhao Yanyan was shocked. It was not so difficult to see that it was a rocket engine. A tail tube nozzle could narrow down a lot of scope. But the fat man instantly connected to the Russian "tornado". That was not as simple as recognizing the rocket engine.

"It depends on the parameters!" Guo Tailai looked as if it was right: "According to your design, if the fuel is appropriate, it will probably be estimated that it is about 30 to 90 kilometers. Isn't this just close to the Russian tornado?"

"Do you know the tornado?" Zhao Yanyan was already shocked. Is the fat man a god? After watching it for a while, she could figure out that she used a computer to simulate a range for a month?

"Nonsense, I never miss all kinds of weapon magazines." Guo Tailai made a thumbs up and pointed at his nose with confidence: "Do military fans know? I am! I am still a veteran military fan. But, by the way, how did you Southern Group play rockets? Snatch food from precision machinery? Have you crossed the boundaries?"

"Do you care?" Zhao Yanyan was stunned and instantly returned to the "big sister" form in the laboratory. He scolded him and explained: "Isn't my Bi-She Micro-Gyro? I went to the unit and jointly developed this rocket launcher."

"Senior sister!" Guo Tailai immediately complained: "Are you still afraid of not having high-precision CNC in precision machinery? Are you still afraid of not having a master with superb handicrafts? Do you need to find an outsider to me?"

Zhao Yanyan's expression changed for a moment when Guo Tai spoke, but he did not hide it from Guo Tailai's eyes. This beautiful senior sister is probably not so comfortable when she arrived at the new unit. Thinking of this, Guo Tailai felt a sense of pity and his tone softened: "Don't worry, leave it to me!"

"There may be trouble." Zhao Yanyan hesitated for a moment, and finally said: "Oh, I'll think of another way."

"I've seen the stuff." Guo Tailai smiled at Zhao Yanyan: "I just want to leave after arousing my interest. I'm not so playful!"

Looking at the fat man's unpretentious smile, Zhao Yanyan finally laughed out loud. He had been hesitating, but now he has finally made up his mind. As long as the thing comes out and the effect comes out, there should be nothing to say, right?

"However, senior sister, your design..." Guo Tai looked at the picture and touched his chin and thought, "Does the above plan to introduce a tornado in the near future? Senior sister, are you planning to run with him? Or are you planning to overwhelm them?"

Guo Tailai has seen many domestic rocket launchers in his future dream. His various performances are so crazy. His range ranges range from dozens of kilometers to nearly five hundred kilometers, and his shooting accuracy of four hundred kilometers can be controlled within 600 meters, which is as exaggerated as a missile.

The design of Zhao Yanyan's rocket engine is already a bit like the A100 in the dream of the future. The A100 rocket launcher is also the most similar to the performance of the Russian tornado rocket launcher, and even the overall appearance is similar to the Russian smerch rocket launcher. The range is similar, so Guo Tailai asked this question.

At this moment, Zhao Yanyan's heart was already full of shock. Just because he took out a design drawing of a rocket engine, Guo Tailai immediately guessed that he planned to introduce a tornado in the near future. Is the fat man a little too keen?

However, compared to the secret of Guo Tai's introduction of tornadoes, Zhao Yanyan was more concerned about Guo Tai's last point: "Press them up? What does it mean?"

"If you slightly improve the design and use a two-stage rocket, the effect will be better. The thrust will be greater and the range will be longer. The second-stage rocket will fine-tune the direction target, and the accuracy will be higher." Guo Tailai explained with a smile: "Of course, the launching drugs must be optimized."

"Are you serious?" Zhao Yanyan was stunned. It was normal for the fat man to tell at a glance that it was a rocket engine. It was not surprising that he could tell that the gyroscope and small rocket engine were used on rocket launchers. But the fat man said that his design could be improved as soon as he opened his mouth. Isn't this too exaggerated? The actual object has not yet come out and there are no experimental results, so how dare you say that?

But the next moment, Zhao Yanyan remembered the thing that the fat man solved with one sentence before graduation when he was stuck at a certain point, and couldn't help but feel moved: "Is the change big? If the change big, I will do two sets, just do parallel comparison experiments."

"Try it, I'll get the processing done, you get the control system for the two-stage rocket launch!" Guo Tailai didn't say that. After all, he was a poor student and had never learned the engine course. He had to take out an engine that was beyond the design of Zhao Yanyan and was a rocket engine, which was really exaggerated.

However, Zhao Yanyan seemed to be used to the fat man's surprise from time to time, but instead was full of confidence in Guo Tailai.

A military green truck covered with a back hull was parked in the yard, and it was already parked there when they came in. Zhao Yanyan led Guo Tailai to the back hull of the truck, took out the key and opened the lock: "The raw materials are all here, take as much as you need, and put the finished semi-finished products here."

Guo Tailai looked through the light and found that there was a metal material of sufficient size. He picked up a small piece and noticed that the weight was wrong when he started. It was lighter than ordinary steel, which was very good. I remembered that Zhao Yanyan said that this new alloy has good heat resistance and a significant improvement in wear resistance. It is estimated that the processing difficulty will not be low.

"Show me your design drawings." Zhao Yanyan suddenly remembered something and asked Guo Tailai to look for the design drawings.

"Are you sure? Senior sister!" Guo Tailai couldn't help but feel speechless: "Even if I use the cad to quickly draw pictures, I'm afraid I'll get it after I graduate. Are you sure I'll want it now?"

As an engineering person, how could he not know what the workload is to draw a whole set of design drawings by himself? Guo Tailai only saw this set of drawings for less than two hours today, which made him come up with an improved set of drawings, which would definitely make things difficult for others.

I wanted Guo Tailai to talk to him about improvement ideas immediately, but when the fat man wanted to produce four sets of engine parts by himself, Zhao Yanyan still held back. When the production was done, he saw the experimental results, which was more convincing than the dry explanation.

Guo Tailai first recalled the parts needed for the things he wanted to make, and then began to carry the raw materials in a planned manner. He moved as much as he could tonight, so as not to finish it, so that he would have to move it to the car in the morning.

Zhao Yanyan is a girl. No matter how strong his combat power is, Guo Tailai did not ask her to do such heavy work. At most, he just wanted Zhao Yanyan to control the handle of the trolley. All the tiring work of moving materials was done by Guo Tailai alone.

"Huh?" Although Zhao Yanyan didn't do it himself, when he saw Guo Tailai alone, he couldn't help but exclaimed: "Fatty, when did you become so strong?"

"Please, senior sister!" Guo Tailai certainly would not confess to Zhao Yanyan that the nanorobots stimulated the repair of muscle fibers every day for so long, causing their muscle strength to become stronger and stronger. He could only make a speechless expression: "I am a good fitter at least. If you use all your strength to create various parts every day, you can have such great strength."
