my scientific age

In terms of mechanical strength, the theoretical height and practical experience of every project member present far exceeds that of Yu Hua.

In terms of mathematical strength, to put it slightly exaggeratedly, the sum total of everyone is not even qualified to carry Yu Hua's shoes.

Multi-threaded work, up to [-] million operations per second, the purest humanoid computer, the most direct scientific research multiplier.

Yu Hua sat in the center with an expressionless face. His thinking computer was operating at its highest efficiency. He held a pen in his right hand and continued to write out data one after another on the draft paper. Then the relevant staff sent the draft paper recording the correct data as quickly as possible. Go to the work area of ​​each group, and each group member will carry out the next design work based on these data and madly advance the project design progress.

The whole process was extremely efficient and fast.

Inside the door, lights symbolizing civilization and hope shine.

Outside the door, soldiers wearing gray-blue military uniforms, like the sharpest spears, stood in the hazy night before dawn, clutching brand-new medium-sized formal rifles, in the highest alert state, risking their lives with their bodies and lives. Guarding the small courtyard behind him.

Time passed slowly, and a red light appeared in the distant sky. A ray of light passed through the horizon and reflected in the sky.

Before I knew it, it was dawn.

The courtyard was quiet, and the atmosphere was somewhat depressing and tense.

Next to them, Zhuang Qianding, Zhu Rui, Wang Chong, and members of the 40mm anti-aircraft gun project team stood, silent and waiting quietly.

The other researchers remained quiet when they saw this.

Everyone's eyes focused on Yu Hua in the center of the room.

Yu Hua, who had been working at high intensity for a long time, looked solemn and solemn at this time, looking at the document report placed on the desktop, and there was a row of words written on it - [40mm anti-aircraft gun design report]

This is the result of the 40mm anti-aircraft gun project team. The appearance of this report declares that the entire project has completed the drawing design work, completed the preliminary process, and is waiting for acceptance and approval.

The 40mm anti-aircraft gun project is an imitation work using the Bofors 40mm anti-aircraft gun as the prototype gun. Yes, it is the Bofors 40mm L60 rapid-fire anti-aircraft gun with the best comprehensive evaluation and actual performance in history. It has every With a rate of fire of 130 rounds per minute, a total gun combat weight of 500 kilograms, and a total production volume of 6 guns.

For later generations, this is a legendary veteran.

Now, this is the most advanced single-barrel rapid-fire anti-aircraft gun in the world.

As a military fan, Yu Hua spent some time fully understanding this legendary veteran that was born in 1928 but became popular in World War II, from the gun mount to the ammunition supply mechanism, from the barrel material to the sight device, from the full gun drawings to There is no missing part in the drawings of each component, inside and out.

Yu Hua raised his head and glanced at Zhuang Qianding.

Professor Zhuang nodded solemnly.

"It's been nearly two months since the project was established. I hope it can succeed." After receiving the reply, Yu Hua took a deep breath, with anticipation in his eyes, and opened the 40mm anti-aircraft gun grouping design report in front of him to obtain the data. , and then mobilized the thinking computer with little available time, and began to conduct the most stringent secondary recalculation verification of the reports and drawings.

Strict and demanding, this is Yu Hua's standard.

According to regulations, after all sub-projects of the heavy weapons project team complete the drawing design, they must undergo a second recalculation for theoretical verification. After passing the verification, they will be reviewed by the top scientific group before they can move to the prototype weapon manufacturing stage.

During the second recalculation, there must be no omissions or errors anywhere, whether it is drawing lines or marked parameters.

If you make a mistake, you will have to go back and start over again without any room for negotiation.

Data were extracted one by one and transformed into three-dimensional structural diagrams. As the data continued to increase, data-simulated parts were born one after another. In my mind, a single-barreled anti-aircraft gun based on the design parameters of the 40mm anti-aircraft gun project gradually appeared. 40 mm barrel, 56 times the barrel length, 60 times the water-cooling casing length, rifle-like loading structure ammunition supply design, high-level universal modular base, the entire anti-aircraft gun is highly similar to the original Bofors anti-aircraft gun, but at the base and details have been changed.

The original anti-aircraft gun did not have a modular base design concept. It was mainly used for air defense and adopted a four-wheel traction design. However, the current version of the 40mm anti-aircraft gun was added to the high-level universal design by Yu Hua and Zhuang Qianding, with a minimum depression angle of 8°. .

The reason for adding this design is entirely a matter of demand.

As a project second only to the 105mm howitzer, the 40mm anti-aircraft gun has immeasurable importance and role. In the foreseeable future, it will be the most important air defense weapon of the Eighth Route Army and even the People's Liberation Army in the next 20 years. However, optical air defense is far from the best. Not enough, the economy of the base area is far from reaching the level of prosperity of "cannonballs washing the land".

Then, Yu Hua added anti-tank use.

Yes, both anti-aircraft and anti-tank.

After all, this is how the 88 gun in Deutsche's house next door is used. It raises its head to masturbate and lays it flat to shoot tanks.

For the monster room environment in Europe, the Bofors 40mm L60 rapid-fire anti-tank gun has obviously insufficient lethality when used against anti-tanks. But if it were to be used against Japanese tanks in East Asia, sorry, the lethality would be adequate.

With a muzzle velocity of 881 meters per second, a 40mm caliber, coupled with tungsten-core armor-piercing bullets and a rate of fire of 130 rounds per minute, the anti-tank capability of this anti-aircraft gun is simply better than the professional counterpart 37mm Pak anti-tank gun next door. times, completely worthy of the crazy evaluation.

Fake anti-tank gun: 37 mm caliber, 42 times the barrel length, 13 rounds per minute rate of fire, 745 meters per second muzzle velocity, [-]-degree left and right direction of fire.

Real anti-tank gun: 40 mm caliber, 56 times the barrel length, 130 rounds per minute rate of fire, 881 meters per second muzzle velocity, 360° circumferential firing range.

There is no problem with the barrel parameters.

There is no problem with the design parameters of the ammunition supply structure.

There is no problem with the stress parameters of the modular base.

There are no problems with the recoil machine and gun body structure.

There is no problem with the Red Star tractor towing solution.

The parameters marked on the design drawings are correct...

Artillery simulation test in extreme low temperature environment of [-] degrees below zero...

Yu Hua followed the previously formulated standard verification process and conducted the most stringent calculations for every data and every part structure design.

All around, everyone was expecting and worrying, holding their breath and not daring to take a breath for fear of affecting Yu Hua's calculations.

Zhuang Qianding looked solemn and serious, eagerly waiting for Yu Hua to give the recalculation results. Although he had checked it three times before arriving at the project team compound, he still did not relax.

Zhuang Qianding is not worried about errors in the drawings, only about design flaws.

Because this is a weapon, not a mechanical part.

If a weapon was developed and put on the battlefield, but it failed to function properly due to design flaws, resulting in the sacrifice of soldiers in vain, then Zhuang Qianding would not be able to forgive himself.

What exactly is the design flaw?
Will the extreme low temperature environment in the north freeze the artillery and prevent it from firing normally?
