The ups and downs of life in the Siheyuan

Having research experience in counter-artillery radar, everyone wants to do some military-related application research.

Civilian technology research can easily expose laboratories, while military research can enhance the construction of the military and help them come to light as soon as possible.

“Okay, everyone’s ideas are good, but don’t forget our essence. As long as the funds are sufficient, we still need to carry out longitudinal research.

Our core is basically chip technology research.

I have a military project on hand, and I hope I can get some funding by then.

Wafer research cannot stop, and the automation of photolithography technology can be advanced.

We can turn to the automatic control solution for civilian use, but it should not be too complicated and should be made into multiple small modules, such as various registers, buffers, encoders, etc.

In this way, even if someone notices it, there won’t be much association.”

After Li Yuan finished speaking, everyone began to re-plan their work.

Except for the lithography machine research group, which still retains some work, other groups have all begun the research and development of basic components.

Li Yuan returned to the second workshop and continued his work.

"Lao Li, I heard that your project funds have shrunk significantly?" Representative Tong gloated.

"You look happy?"

"No, I've been to several research institutes recently and I'm very disappointed. They don't seem to have any ideas on how to design chip circuits.

Now everyone is studying Li Lou. They enlarged your mask several times and began to study the design principles of the chip."

"Aren't there design plans and drawings? Why do we need to study mask boards?"

"Hey, I don't know either."

Looking at him, you knew that he knew the reason, but Li Yuan didn't bother to pay attention.

Representative Tong held it in for a long time. Seeing that Li Yuan didn't answer, he took the initiative and said:

"Chip technology is a brand new technology for everyone, and I don't think they can do anything good for a while.

Your project has been stopped. I happen to have a few projects here. Why don't you take over them? "

Li Yuan was secretly happy, but pretended to be calm on the outside.

"No problem. The research project will definitely require funds. You quote a price and we will evaluate it and see if we can do it."

Seeing Li Yuan's calm expression, Representative Tong felt uncertain.

"It's all revolutionary work, so why talk about funding!"

"Are there any fees for water and electricity? Are there any fees for employee wages and benefits? Do you need materials for research? Do you have to spend money to buy these?

You said that when more than 6 J-100s were built, all the materials for five to six hundred sets were consumed. This was the investment after finalization.

When we engage in scientific research, do we need to conduct repeated experiments and verifications to determine the design?

So, Lao Tong, since you recognize our laboratory, you have to consider whether we should pay for the project.

If you can change the laboratory to your military system, I won’t say a word today.”

"Okay, I'll go back and report to the leader. These projects will be left here for you."

"Don't worry, we will discuss it in detail after you decide which projects to invest in."

Representative Tong took the information and left.

Li Yuan stood up and watched him disappear behind the filing cabinet with a smile on his face.

Three days later, Representative Tong came here again and presented three projects.

They are the J-6's flight control system, radar high-power amplifier and radar signal receiving module.

It can be said that the following projects are not difficult for those who can master them, but not difficult for those who are difficult.

The first project is a little more difficult. This one can no longer use special chips, and has to design a special flight control computer and related sensors.

The earliest flight control technology was mainly realized by simple mechanical components such as cables, pulleys, connecting rods and cranks, that is, mechanical control systems.

During the actual control of this system, the pilot needs to directly transmit the force exerted on the cockpit control device to the aerodynamic control surface.

Then the aerodynamic hinge torque on the rudder surface allows the pilot to obtain force and displacement feedback through the mechanical linkage, thereby achieving control of the aircraft's attitude and flight trajectory.

Later, as the size of the aircraft increased and the flight speed exceeded the speed of sound, the mechanical control system could no longer meet the demand.

Especially when the aircraft's flight speed gradually enters the transonic speed region, the forces on each wing of the aircraft increase sharply, and it is difficult to move the aircraft's wings by manpower alone.

Therefore, servo mechanisms are used to provide aerodynamically assisted hydraulic boosters to reduce the effort required for control.

The above two changes were both based on mechanical transmission. For example, driving schools in later generations still used mechanical transmission steering wheels even around 2000.

Without any strength, there is no way to turn around in place.

This control system has a fatal flaw, and any failure at any point will affect the specific operation.

Therefore, automatic control technology using the closed-loop feedback principle was later developed, which is generally called "fly-by-wire control".

The so-called telex control means that the mechanical channel is completely replaced by the telex channel.

Sensors are used to measure changes and transmit signals, and then the computer receives the signals for processing and calculation.

and issue commands to control hydraulic brakes or flight control surfaces.

In this way, the flight control computer was born. Many controls are completely controlled by the computer through the collected information, which automatically controls various parts of the aircraft in a closed loop.

The pilot no longer needs to manually operate these components, he only needs to input appropriate instructions and monitor the flight status.

The West proposed this concept in the 50s, and it is still in the laboratory.

The flight control computer is still a large tube or transistor computer and cannot be transplanted to an aircraft.

Domestic research began in the 60s, and the methods are similar to Western research.

Of course, today’s computers are still tube computers, and sensors are basically purchased from abroad.

After the 621 Laboratory developed the chip, several military research institutes thought of researching chip technology. The idea was just to design basic logic units into chips.

Attempts have already been started, but progress is slow.

The military bosses had seen how powerful Li Lou was, so how could they accept their plan.

After many communications, it was decided to hand over this project to 621 Laboratory.

When Li Yuan saw this project, he almost twitched with joy.

In fact, he has always wanted to develop microcontrollers, but he had no time and no funds.

He is just the manager of the 621 State Key Laboratory, and all projects in the laboratory require approval from superiors.

It's okay to play with some gadgets, but he can't do anything about complex projects like microcontrol.

For example, for the turbojet-6 engine improvement project, the materials are provided by the military, and there is also 1W of funding.

And this project has no time requirements.

But all three projects have time requirements.

The development time for the flight control system is 2 years, the power components are half a year, and the receiving module is 1 year.

The research and development cost of the first project is 100 million, and the cost of the remaining two projects is 10.

Of course, all expenditures on R&D are included in R&D expenses, including the cost of prototypes or samples.

With the support of superior leaders, the two parties signed an agreement. In order to ensure the interests of Party B, only 10 cash will be paid in the early stage.

The subsequent payment of fees will be discussed based on the project progress assessment.

After all, the laboratory has little ability to pay compensation, and superior leaders will not guarantee it.

With funds and projects in place, the 621 State Key Laboratory began applied research work.
