Chapter 520

Terrible what?

Lisa, is a remnant of the soul, relying on strong faith, has always existed in the world. She is waiting for her lover. The smile of Mona Lisa is the smile of her soul.

Later, she entered her own spiritual world and lived somewhere in her brain.

Because there is a system inside the brain, her spiritual power can follow Qin Guan to the weapons cemetery in 2020. In fact, Qin Guan's past is equivalent to the past of the soul, and the body still stays here.

The system in the brain can carry out material exchange. It is limited to the material exchange of the world and the material exchange of the cemetery in 2020, not the spiritual force in Qin Guan's brain and the material exchange of the outside world.

As for what Lisa wants to wear in her brain, it can be said that it is imaginary. It is like an old grassland hero who has been walking on a Trojan horse, which is also in the spiritual world.

Now, things in the spiritual world can fly into their own physical world. Will Lisa's soul run out and become a person in the future?

Qin Guan is quite worried. His own system seems to have been hiding something from himself. Up to now, although he has done a lot of things beneficial to the motherland by using the system, Qin Guan is more and more distrustful of this system.

"Don't doubt me, it's an accident." just then, the system in the brain sounded a voice: "this is an unexpected illegal process, bypassing my main monitoring and quietly executing in parallel. Now, it has been forced to end by me. There will be no similar situation in the future."

Unexpected illegal process?

Qin Guan is very strange. What does that mean? Is it?

"Yes, I did it." at this time, Lisa was still sunbathing naked at Davis Munson air force base. She lay on the ground and shouted to the sky: "this time, I have successfully given you my bra. Next time, I will have a chance to see you out!"

Lisa is complacent. Although she came from a housewife hundreds of years ago, she is quite smart. In a short time, she can learn Chinese and recite all kinds of books. At the same time, she also began to study the system.

Her research is even faster than Qin Guan's research. She soon found the loophole of the system. Unexpectedly, she executed a secret process and sent her underwear out!

This is just an experiment. Next time, Lisa can go out by herself.

"No, it won't happen again." the system said, "I have the ability to repair myself and have made up for all the loopholes."

Lisa smiled: "there is no system without loopholes. Of course you don't know. I will find out new loopholes. Next time, my process will be more powerful and won't be forcibly closed by you. Darling, wait for me!"

Qin Guan felt that his world was going to be chaotic.

Just in the brain, every time you enter the system, there is such a woman to seduce yourself, and you are already tired of dealing with it. If this woman comes to your real life

Then put her in jail! Yes, if you dare to come out, I'll put you in prison. You don't belong to this world.

Qin Guan secretly made up his mind.

"Creak." just then, the door outside slowly opened. Two workers pushed a small car with a scrapped turbojet -7 engine on it.

Hearing the sound, Qin Guan quickly grabbed the bra and hid it in his arms. Fortunately, the weather is still very cold, so he wears it very thick and can't see anything in his stomach.

"Well, just put it here." Qin Guan said, "well, you can go."

Watching these people leave, Qin Guancai breathed a long breath. It's dangerous. If others see him, I'm afraid he will think he is an obscene and abnormal man. He likes to steal beautiful women's underwear and use it to do that refreshing thing.

Now, let's get down to business and exchange engines!

……

"This engine belongs to full digital control." at this time, Mr. Song is organizing scientific research forces to tackle key problems quickly and prepare to assemble the engine on the body as soon as possible.

While they were studying the data carefully, a technician found something.

What they have just studied is mainly the matching of the engine and how to install it on the rear fuselage. Now, they have finally studied the control system.

It's digital control!

Digital control is relative to analog control. In simple terms, the power output of the corresponding engine depends on the size of the throttle lever used to operate the engine. This is analog control, which changes continuously.

If these analog signals are converted into zeros and ones after a / D conversion, they are digital signals. The computer can only process digital signals.

The previous super seven used an rd93 engine, which is analog controlled. Just use the throttle lever to control the corresponding pipeline, but now, this engine is digitally controlled!

What should I do?

In these materials, there are how to install the engine on the fuselage, but there is no detailed solution to the program problem of digital control.

Suddenly, old song frowned. He knew that his first big problem had really come!

In addition to the engine control, there is also the overall control of the fighter. For example, the Raptor uses four redundancy digital telex, which is also a very advanced control technology.

As for Xiaolong, as a low-cost aircraft, it only uses digital telex in pitch, which can improve the maneuverability at high angle of attack, but it is still ordinary hydraulic control in other directions.

They now imitate super seven. The pitch can be changed by hydraulic pressure. It's very simple, but now the engine is digitally controlled. How to solve it?

Become simulated and replace it with simulated? That won't work. It's a historical reversal. The best way is to continue to use digital telex in pitch and combine it with the engine at the same time.

In this way, for example, when the operating lever is pulled up and the fighter wants to look up, at the same time, the engine knows that it's time to work hard. Without the pilot operating the throttle lever, it can quickly enter the full speed working state, which is more convenient for control.

But in this way, the difficulty will be greatly increased. Our side has just contacted these. Can we succeed?

"Old song, I'm back!" just then, a voice came from outside.

Hearing the sound, old song was immediately happy.
