Siheyuan: Supernatural from the Ninth-level Engineer

Each piece weighs 1250 tons.

It is the largest, heaviest and longest single part directly on the board.

After all, when the 8-ton press is working, the forging hammer needs to move up and down on these four columns to apply forging pressure to the parts on the workbench.

The weight of the whole large press is as high as 12000 tons.

At present, almost all industrial systems in the country are used.

No joke.

"Everyone, this is a model..."

Yang Gang also knew that these tech giants had their own concerns.

Investing in such a huge project must not be easily concluded, even if he is Yang Gang, with Elder Shen supporting him.

Just take the model out.

This was prepared before coming here.

Five C-shaped boards, pasted together into a column, and scattered, are five parts.

"This is a trial production at a scale of 1:100... You can use this model to demonstrate with finite element analysis

Yang Gang didn't say much.

In his original world, the flower gardener made it in this way.

Naturally there will be no problems.

As for the rest, these tech giants will solve it.

A group of bigwigs quickly invested in the calculation and demonstration. In just three days, it was proved that the method provided by Yang Gang was without any problems.

"Mr. Yang, you really helped us a lot!"

"That is, we only thought about how to make them separately before, but we didn't think of using such a method..."

A group of bigwigs said to Yang Gang excitedly.

After solving this problem, many other problems have also been solved.

"Everyone, I'm here to help ourselves."

Since the project is confidential, Yang Gang can't say much.

"In half a year at most, the large press can start to be assembled..."

Old Shen also breathed a sigh of relief.

"The sooner the better, our fighter plane is waiting for its first flight..."

Yang Gang said.

He is very clear that the assembly will start after half a year, and the assembly time of the 370 will not be short, and even the debugging time will not be short.

It will take at least a year and a half to wait until the large press is put into production.

After waiting for such a long time, I naturally don't feel how hard this year and a half is.

With a large press of 10 tons, the Yun-XNUMX will no longer be dismounted due to the lack of large-scale die forging stages in China and the inability to forge and form the entire aircraft frame at one time, resulting in insufficient strength structure.

Perhaps, it won't be long before the flower growers in this world can produce a super plane like the An-225.

"When the time comes, your parts will be processed first."

Shen Lao said with a smile.

Not processing Red Star Rolling Mills?

There must also be other units that need the processing of such parts.

"What? It will take at least a year and a half for the first flight? Mr. Yang, our progress has been seriously affected because the test flight has not been carried out." Cao Feng was anxious.

This is a joke.

Prototyping of fighter jets has been going on for a long time.

Because of the manufacturing process, the structural strength could not meet the design requirements, and the first flight was delayed.

The fighter needs to be tested in order to further find problems and improve.

How can this go on?

"Comrade Yang Gang, now that you know the problem, or else, let's make a prototype for the first flight."

The head of the Air Force frowned.

In his view, there is absolutely no need to wait for the big press to come out.

After the test flight, it was improved. When the large press was developed, the beam of the aircraft was of an integral structure. At that time, it would be directly forged and formed at one time, so it would not be so troublesome.

"It's really a problem. Our progress cannot be stalled because of that."

Yang Gang nodded in approval.

"The J-10 has no engine, and the flight test work continues to be delayed. The J-9 prototype can be prepared for its first flight."

The design index of the J-28 is double XNUMX.

Yang Gang directly took out the full set of drawings of the Wosu 15 engine.

Over the years, the experimental progress of Wojet-15 has been very smooth after the high-temperature alloys that can withstand higher tail nozzle temperatures and the CNC machine tool factory that can process high-precision and complex parts.

However, the avionics system and the bomb load of the fighter are not ideal.

Yang Gang had no choice.

To have high altitude and high speed, but also to carry more ammunition, this itself is not realistic.

Moreover, the J-28 fighters of the double-9 are only to intercept air targets.

"Flying the J-9 first? It's alright'."

Although the Air Force chief was a little dissatisfied, he also knew that there was no way.

If the support cannot keep up, the Air Force will not have better fighters to use.

Waiting for the large press and other supporting equipment to be completed, not only the Air Force is a branch of arms.

"Although the J-9 and the J-10 are very similar, the aerodynamic layout is similar, but the functions are different. The test flight in the early stage was only to demonstrate the various systems and avoid incompatibility problems... Everyone should be clear, we It is to demonstrate the design plan, improve our design, and make our fighters have stronger performance, not when the craftsmanship is not good

Compromise on performance requirements! "

Yang Gang emphasized to many relevant responsible persons.

Lower performance metrics?

impossible!

It will never be possible.

"Mr. Yang, don't worry, we will never lower the indicator."

Cao Feng promised.

"If the performance index is really reduced, we will not do it! According to the information, the MiG-25 is a double-three index. Our foundation is poor, and it has been reduced a lot... Otherwise, we definitely hope that the equipment is better than the MiG-25. A stronger high-altitude high-speed fighter!"

The Air Force chief said that performance cannot be compromised even without the aircraft.

Currently the Air Force has no aircraft in use, and each performance indicator is based on demand.

The speed of the J-7 and the J-8 is too slow.

Flying altitude is also not enough.

".Also, the issue of range, we must find a way to make our J-9 have a combat radius of more than 1000 kilometers, otherwise it is meaningless."

The J-9 project also existed in Yang Gang's original world.

However, it has not been developed.

Yang Gang did not take out the J-9 drawings given by the system, but only took out a W-9 engine matching the J-15.

The designs were all made by Cao Feng, He Guosheng and relevant technical experts from 132, 112 and other units (Hao Zhao's) based on the design of the J-10.

In the process of wind tunnel experiments, there were many models, which made engineering designers discover that the large delta-wing J-10 fighter with canards has undergone some improvements, such as larger canards and larger delta wings, etc. , Equipped with a socket jet engine can get very good high-altitude high-speed performance.

The advantages of the socket jet engine are very obvious in the high-altitude and high-speed performance.

The only downside is that this thing consumes too much fuel.

Fuel consumption problem, is that the problem?

It is a matter of national defense and security, only considering performance, not cost.

484 I didn't even think about retirement, you just thought about retirement?

"Mr. Yang, we have been producing prototypes before. Otherwise, we don't need to produce other prototypes first, and we can directly conduct test flights after assembling the Wojet-15 engine?"

After the meeting, Cao Feng and He Guosheng found Yang Gang.

It is proposed to directly use the previously produced prototype for test flight.

The J-9's requirements for the structural strength of fighters are also not low. But at present, if it is only for the ground roll experiment and the first flight, the flight speed is not fast and the altitude is not high, just to prove that there are no problems with each system, the existing structural strength, Not a problem.

"Are there still prototypes?"

Yang Gang asked.

"There is another one, which was originally used for ground system experiments. We are short on funds. If there are no problems with ground system experiments, we can directly use this plane for rolling experiments, etc...

He Guosheng explained.

There are still two prototypes in the production process, in different production states.

All are used for various ground system experiments.

According to the principles of fighter aircraft design, the avionics 370 system, flight control system, radar system, power system, weapon system, etc. of the fighter aircraft all need to be fully tested on the ground to ensure that there are no problems before proceeding to the next step of development work.

Hongxing Steel Rolling Plant has a lot of funds. Even if several prototypes were destroyed by static tests, some prototypes were still produced as experimental platforms.
