After some calculations, Chen Tu found that it was perfectly suitable for helicopters. With a load capacity of 30 rat tons, it's perfect.

After completing the modeling, Chen Tu directly projected the engine in front of him. As a weapon of war, a streamlined design is essential. In terms of shell selection, Chen Tu chose a low-quality magnesium-aluminum alloy, which greatly reduced the weight of the helicopter itself in terms of quality.

In terms of energy output lines, Chen Tu follows the universal design of helicopters, and adds source crystal energy bars to the tail. And on the tail wing is the use of pani alloy, although this alloy is metal, but insulated, can effectively prevent the energy bar from being hit, the possibility of explosion.

In terms of driving, this is something to consider. Rats are no bigger than humans. Also, the field of view ahead must be optimal.

In order to solve a large number of complicated operations, Chen Tu used a WON chip. It is obviously much smarter to operate the helicopter with won. Of course, it would be better if the simulation cabin equipment was installed, but the simulation cabin is too expensive, and the ordinary simulation cabin is not shockproof, and it is very easy to have problems and is not easy to maintain in the changing situation of war.

In terms of piloting, Chen Tu chose the same driving mode as the spaceship, so that some mice are also familiar with this kind of roulette operation, so that no mice can fly a helicopter.

The reason why helicopters are powerful is that they are a big killer, and the key to it lies in weapons. With a helicopter, it can only be said that it is half built.

The other half is the choice of weapons, for this assembled helicopter, Chen Tu is made according to what the house can produce. Although core components like WON still need to be purchased from humans, this is not a problem.

WON is already blooming everywhere for human beings, even high-end WON doesn't cost much money in terms of prices, ordinary people can consume it, and there is not much pressure on Chen Tu to buy.

As for the fighter planes, Chen Tu felt that it was better not to produce them for the time being, because first, Chen Tu had not yet reached the point of long-range combat, so the struggle for air supremacy and the need for air supremacy were limited to low altitudes, and second, the cost of fighters was higher than that of helicopters. Moreover, to this day, the shadow of fighters can still be seen in human weapons, which shows that the technical content of fighters is also very high.

Chen Tu didn't have that much time to design a weapon that wouldn't be used for the time being.

In terms of armament, Chen Tu offered two options, one was a honeycomb rocket, which was designed to fight armored forces. As long as you are targeted by rockets in the sky, the chance of being able to escape is basically zero. The rockets of the rats are already very powerful, not to mention the rockets of the crystallization level of wisdom accumulated by mankind for thousands of years.

In the choice of model, Chen Tu chose the Ice-30, which can carry 30 rockets, and the total weight of the weapons on both sides of the helicopter is only five tons.

On the other hand, Chen Tu chose the Fitel gun that strikes on the ground, and the special feature of this gun is its heat dissipation performance. It has five barrels, but the one that really fires bullets is the one in the middle, and the others are barrels made of special alloys, which can fire tens of thousands of bullets in a row without bursting.

Mounting this weapon can provide powerful fire support on the ground, whether it is a city battle or a field battle, it can make the enemy feel that this is a flying fortress.

After ten hours of refinement and meticulous calculations, Chen Tu finally generated a file of the part drawings of each component. Chen Tu named the helicopter he designed the Yin-1 and Yin-2 helicopters.

The origin of the word Yin Ying is from Yin Ying, Chen Tu did not plan to tell Yin Ying this name, he just thought the name was very good.

Out of the top floor, it was already one o'clock in the morning. The administrative hall has turned off the lights, and only a few guards are on duty.

"This classmate, where is the reception room in the administration building?"

At such a late hour, Chen Tu did not plan to return to his residence, and planned to stay in the reception room for one night.

"Your Excellency the Governor, the fifth floor is there. Need me to take you? The guard said sincerely.

Chen Tu waved his hand and said, "Thank you, no need." "When the administration building was under construction, there was no elevator installed, so Chen Tu could only walk from the top floor of the thirteenth floor to the fifth floor.

Chen Tu, who was already sleepy, went down so many floors and felt sleepy, Chen Tu yawned. Heart, these details also need to be solved urgently.

The entire fifth floor is the reception room, and because the high-level exchange activities in the house city are not frequent now, there are only a few houses that live in perpetuity.

On duty in the reception room was an elderly aunt, who was reading a book carefully.

"Hello Auntie, I want to stay here for one night."

"Live here? Do you have a certificate? You can't live here without a certificate from the Administration Department. The aunt on duty said. Without waiting for Chen Tu to speak, the aunt continued: "However, it's so late, the officials are all off work, and you can't find it even if you go." Well, this is the key to number 519. Stay here tonight, and come early tomorrow morning to return the keys so that no one knows. ”

"Okay, thank you, Auntie."

Chen Tu also disdains to say who I am, as long as I can stay, and other things will be talked about tomorrow.

The condition of the reception room is very basic, surrounded by concrete walls, and there is no decoration. This is also the characteristic of the rat civilization, which is very rough and simple.

Chen Tu walked to the bathroom, to Chen Tu's relief, there was hot water here, he took a bath happily, and then lay on the soft bed, this weather, there is no need to cover too many clothes, the cool breeze outside the window, Chen Tu soon fell asleep.

"Little comrade, little comrade, it's time to get up."

As soon as it was dawn, the aunt on duty began to knock on the door of No. 519, and although Chen Tu slept late, she slept soundly. was woken up early, and Chen Tu didn't feel tired.

Chen Tu folded the futon on the bed and handed the key to his aunt.

"Thank you, Auntie." Chen Tu bent down and thanked him.

"Hey, that's polite." The overwhelmed aunt who was thanked hurriedly said that she was not used to this feeling of being thanked.

Zhulu's office was on the second floor, and Chen Tu first went to the cafeteria for breakfast, and then went to the office to wait.

Zhulu also came very early, and he had already eaten at seven o'clock and came to the office.

"Huh? Why is the Governor here? ”

"Yesterday afternoon, I was engaged in R&D on the top floor, and I didn't go back, so I stayed in the reception room for one night."

"Oh, I see. Are we going to produce new products? The keen Zhulu smelled the reason and asked questions.

Chen Tu nodded and said, "I retro a human helicopter, this weapon is much better than the performance of rats. Therefore, I am going to produce a batch and put it into the battlefield to see the effect. ”

Chen Tu asked again: "Where do our engineers work?" ”

Takeka replied, "In the ginkgo orchard in the Yacheng Machinery area, where they live and work. ”

"Today, you just put down what you're doing, let's go to the ginkgo orchard and let the experts there see my design."

Zhulu nodded, and in Zhulu's psychology, his admiration for Chen Tu increased again. Chen Tu's talent is not only in governance, but also in IQ, and he has come up with a design plan for a new type of weapon in such a short period of time.

Of course, in Chen Tu's view, his own practice can only be called a small skill of carving insects. It's like a human child building blocks.

"Hello, Your Excellency the Governor, I'm the director of the Yajo Machinery Research Institute, Blaney." When Brieney saw Chen Tu, he bent down and saluted.
