Chapter 325 Liu Guowang's Spring
Five minutes later, the second alarm bell rang!
Not only the test workshop was boiling, but also the sound of alarm bells seemed to be vaguely heard in some nearby factories.

"It seems to be a test car alarm!"

"I heard that the 300-hour long test started today, so it should have already started!"

"Our turbofan engine successfully passed the first test run, and I don't know what it will be like in the 300-hour long test."

"."

Amidst the enthusiastic discussions among some employees, the alarm bell rang for the third test run, followed by a loud voice in the test drive control room, "Start the engine and reach the idle state!"

One of the test commanders started the motor, and the engine started to rotate under the drive of the starter motor, reaching a certain speed.

The fuel adjustment is turned on, and the engine starts to ignite!
The unique sound of the engine's operation sounded, and even the tail jet of the engine could be seen with hot high-speed airflow, and the engine reached the idle state.

After 3 minutes, that is, 180 seconds later, the resonant voice of the test commander sounded again, "It reaches the rated thrust state of 0.5!"

One of the testers pushed the throttle operating lever, the throttle of the fuel regulator opened slightly, and the thrust of the engine began to climb until it reached the rated thrust of 0.5.

The digital display on the display is very clear, the current thrust state is 82.5KN!

After 5 minutes, that is, 300 seconds later, the test commander issued another order, "The engine reaches the middle thrust state!"

The tester started to push the accelerator lever again, and the thrust of the engine began to climb rapidly, from 82.5KN to 165KN in just a few seconds.

Accelerate from [-] kilometers in three seconds!

The situation of this engine is similar, showing great acceleration performance, and the thrust can quickly climb from 80+ to 165KN in just a few seconds. The performance of this aspect alone is enough to kill all current military turbofan engines. .

If such an engine is installed on a fighter jet, the pilot only needs to push the throttle lever a little, and the fighter jet can easily break through the speed of sound without any difficulty.

In the huge test drive control room, no one spoke, and everyone looked serious and calm. At this time, some people finally couldn't calm down, and obvious excitement appeared on their faces.

Too awesome!

It is such a performance that brings you a lot of surprises!
The engine maintains an intermediate thrust state, which is very stable. The display shows a thrust of 165 kN all the time. Even if there is a slight fluctuation, the fluctuation value is definitely within 1%, which also shows that the working state of this engine is very stable.

This is also a performance index of the engine. The smaller the thrust fluctuation, the better, which shows that the engine works more smoothly and is more reliable!
The engine worked for 10 minutes in the middle thrust state, which is also the requirement of the 300-hour long-term test technical outline, and there are very strict regulations on how long it should work in any state.

The test commander kept staring at the time, and when the 10 minutes were up, his loud voice sounded again, "The engine has entered the state of maximum afterburner!"

The test driver pushed the throttle lever to the maximum!
The sound of the engine working is obviously increased, but experienced people know that this is a very normal phenomenon. It can be heard from the sound that the engine is working very normally.

The thrust of the engine on the display rose rapidly!
The good acceleration performance is fully reflected again!

In just a few seconds, the thrust of the engine rose rapidly from 165 kN to 245 kN!

With such a huge thrust, any aircraft can fly at high speed!
Afterburner fully open!

The maximum thrust is 245 kN!

Seeing this scene, almost everyone was boiling. There are not many military turbofan engines that can reach this level of thrust. Looking at the whole world, there are military turbofan engines with such a huge thrust, but their volume and weight ratio This engine is much bigger.

The thrust-to-weight ratio is often one of the important indicators to measure a turbofan engine. The thrust-to-weight ratio of the LH165 turbofan engine is 12, which means that the rated thrust is 165 kN, and the engine weighs only 1375 kg.

If the thrust-to-weight ratio is calculated according to the afterburner thrust of 245 kN, then the thrust-to-weight ratio of this turbofan engine is as high as 18, which is simply against the sky!
It is indeed the world's top military turbofan engine!
Others only dare to maintain the afterburner state for 30 seconds, and few dare to reach 45 seconds, because the afterburner state is the maximum state of the engine, which is a test for the entire engine. Generally rarely used.

The afterburning state of our LH165 turbofan engine dare to maintain for 180 seconds, that is, a full 3 minutes, which is also the requirement of the technical outline of the test run. In fact, in the actual use process in the future, the afterburning state should be maintained for about 300 seconds Status is also okay.

The engine reached the afterburner state in just a few seconds, with a thrust of 245 kN, and cheers erupted from the huge test control room!
After a brief cheer, many eyes stared at the thrust number and time on the display screen, reaching 180 seconds.

The test commander said loudly, "Return to the middle thrust state!"

Hearing the instruction, the test driver retracted the throttle operating lever, let the thrust of the engine drop, and then stabilized at 165 kN.

Next, except for the maximum afterburner state twice a day, each time for 180 seconds, the rest of the time is in the middle thrust state until the 300-hour long-term assessment test run is completed!

The cheers sounded again!
"Successfully passed the 180-second afterburner!"

"Our engine is so good, I feel that even if it lasts for 180 seconds, it seems to be easy."

"."

Seeing a lot of excited cheers, he smiled slightly, and of course he was in a good mood.The engine returned to the middle thrust state, and Lin Feng, Fang Anping and others could also leave, and the next thing could be left to the test workshop.

Provincial Airport.

When Lin Feng and others participated in the 165-hour long-term assessment and test run of this LH300 turbofan engine in Shenhai City, an international flight landed at the airport, and most of the passengers who got off were black-haired and yellow-skinned people. But there are a few foreigners who are more conspicuous.

In the mid-90s, although there were not many foreigners who came to our country by plane, there were still some, and everyone was used to it, and gradually felt that this was a very normal thing.

One of them was a tall foreigner, unsmiling and serious, followed by two attendants, one of whom was a beautiful young woman with blond hair and blue eyes and a tall figure.Their identities are business inspectors of a large enterprise in a beautiful country, and they come to consider the investment environment.

In fact, this is only a superficial identity, and it is also a kind of cover-up. I am afraid that almost no one would think of their real identity. Of course, their trip is not an investment investigation, but has another purpose.

Liu Guowang is a designer of Leihuo Aircraft Design Center and is participating in the design and development of stealth strategic bombers. However, he took half a day off today to visit the staff's residential complex.

The employee housing complex located in HX District of Fenghuang City is the fastest construction. The first batch of people have already got the keys and have basically moved in. The second batch of people is expected to get the keys soon.

The construction progress of the employee housing complex located in the south of the provincial capital is a little slower, but the delivery of the first batch is also fast. It is estimated that the house distribution will start within a few days.

After looking around in the staff housing complex, Liu Guowang hoped that he could get a two-bedroom apartment with a better floor, and then ride his bicycle back to his current dormitory.

This is the house rented by the Leihuo Aircraft Design Center for the employees. It used to be a dormitory building for the employees of a certain unit. There are three or four buildings in total, and two people live in each room.

This kind of housing conditions is of course far worse than the future employee housing complex. Along the way, Liu Guowang was riding a bicycle while thinking about moving into a new house in the future. Suddenly, an exclamation sounded.

He was taken aback. He was riding a bicycle while thinking about the new house, and almost ran into someone, less than half a meter away!
When Liu Guowang was surprised, the other party turned out to be a foreigner. To be precise, she was a young foreign girl. She was very fashionable, blond, tall and good-looking. She should be able to score 80 points.

"sorry Sorry!"

Because he almost bumped into someone else, Liu Guowang quickly apologized on his own initiative.

The foreign beauty spoke blunt Mandarin, "Oh, it's okay."

It could be seen that the foreign girl was not angry or blamed. Liu Guowang felt relieved and was about to ride away when the other party stopped him.

"Sir, can you do me a favor?"

Liu Guowang stopped quickly and asked, "Is there anything I can help you with?"

Seeing that the other party was a beautiful foreign beauty, Liu Guowang felt a little hot in his heart, and even quietly looked at the other party more.

The beauty smiled sweetly, and the smile was very bright. Liu Guowang was almost intoxicated by this smile, and his heart was pounding even more, and he actually became a little nervous.

"Sir, I'm here for the first time and I'm not familiar with it. Can you act as my guide? I can pay you ten dollars an hour, how about it?"

The beauty took out several US dollar bills from her bag, including ten dollars and one hundred dollars.

As a member of Leihuo Technology Industrial Group, although the monthly salary and benefits are good, it has not reached the level of ten dollars an hour. In some units and enterprises, the monthly salary is only two to three hundred yuan Money, this is only thirty or forty dollars, or forty or fifty dollars a month.

Liu Guowang's salary income is good, not counting the usual bonuses and other benefits. The monthly salary is about [-] yuan in US dollars. After all, he is a newcomer. He joined Leihuo Technology Industrial Group not long ago and has not yet obtained the title of engineer.

It doesn't matter if it's money or not, the main thing is that beautiful women are eye-catching.

Liu Guowang's heart skipped a beat, and he quickly agreed, "Yes, I happened to ask for leave this afternoon."

The smile on the beauty's face became brighter, and she walked side by side with Liu Guowang, the one who was relatively close, and could even smell the fragrance emanating from this western beauty, um, it smells so good.

The beautiful woman is generous, chatting and laughing with Liu Guowang.

Although the mandarin of the other party was relatively blunt, there was no major problem in communication. The two chatted easily in this way, and Liu Guowang also officially acted as a guide. The afternoon seemed to pass quickly.

In the evening, the beauty took the initiative to treat guests, and treated Liu Guowang to a big meal at a restaurant on the street. Not only did she pay a total of [-] US dollars, but she also left contact information for each other.

Liu Guowang's contact information is a lock-in number, a number display pager of his own, and an office number.The western beauty left a cell phone number, which was her own cell phone.

Going back to his dormitory and lying on the bed, Liu Guowang felt that he was very lucky to meet such a western beauty. He took three ten-dollar bills and looked at them, and then thought to himself, could it be that she has something for me? Good impression.

In the afternoon, the western beauty praised the Huaxia man more than once, and expressed her desire to find a Huaxia man as her boyfriend. Liu Guowang felt that he should have hope.

I thought in my heart, if my girlfriend is such a western beauty, how much face would be, how great it would be!

Air Force, a certain base.

There are a lot of planes parked here, including fighter jets and bombers. Especially in the distance, there are more than a dozen active bombers parked neatly, which is very spectacular.

On the tarmac, there was a bomber parked there. Some ground crews were busy, carrying out a series of inspections and preparations. Not far away were several military officers and people from Leihuo Technology Industry Group.

The world's leading level of precision-guided bombs, of course, must be well tested, no, the preparations have begun.

This was originally a precision-guided bomb mounted on the stealth strategic bomber, but that plane is still under development, so the verification of this precision-guided bomb is carried out on the active bomber.

Its versatility is very strong, not only the stealth strategic bomber can be used, but also a variety of aircraft in active service can be mounted and used, such as this bomber in active service.

The preparations were carried out in an orderly manner. It didn't take long for the first precision-guided bomb to be pushed over. The ground crew opened the army-green packing box, and inside was a bomb weighing nearly two tons and several meters long.

"Wow, this is a precision-guided bomb!"

"Looks good, it's nothing like the traditional bombs we've seen!"

"Can its accuracy really reach within 10 meters!"

"."

A lot of people surrounded them. They were all from the military. It was the first time they had really seen such a precision-guided bomb. Come over together.

Seeing everyone's great reaction, Wu Chunyu and others smiled proudly.

A deep sense of pride in everyone's heart!

Originally, they did not expect that they would be able to participate in the development of the world's top precision-guided bombs, but after joining Leihuo Technology Industrial Group, everything became a reality. The successful development of the world's most advanced precision-guided bombs is just the beginning. A variety of world-class weapons will be developed.

For example, the world's most advanced air-to-ground medium and long-range missiles can also be launched at an altitude of [-] meters and can accurately hit targets [-] kilometers away. It is also one of the weapons that this stealth strategic bomber will carry.

"Mr. Wu, this missile looks good."

"Of course." Wu Chunyu is not humble at all, and there is no need to be humble, because this is really the most advanced precision-guided bomb in the world. He participated in the development of this precision-guided bomb, and he is very clear about its performance. .

"This is currently the most advanced precision-guided bomb in the world. It can be dropped at an altitude of 10 meters, and it is accurate within [-] meters. It is all-weather and not affected by weather conditions. It will not be surpassed in another ten years!"

Oh my God!

Is it so awesome!

There was a burst of exclamation all around, everyone was shocked, and some people thought in their hearts, is this true, Mr. Wu, are you sure you are not bragging?

After regaining consciousness, several ground crews began to seriously mount this precision-guided bomb on the bomber. Even though it was the first time, the mounting was completed in a while.

"Its design is so reasonable, it fully considers ergonomics, it is very convenient to mount, and the efficiency is very high."

"With such a heavy and big bomb, I thought it would take me a long time, but I didn't expect it to be done in a few minutes!"

Soon, the second bomb was also pushed over, and several ground crew members became more proficient, and quickly hung up this bomb.

A total of six bombs were mounted. In fact, this bomber should be able to mount eight bombs, but the next step is only for bombing verification, a total of six is ​​enough.

The precision-guided bomb was mounted, all preparations were in place, and the meeting before the bomb verification was also held.

Leihuo Technology and Industry Group was led by Wu Chunyu, as well as some technicians from the bomber development unit. In addition, they were all military personnel, including the pilots who would perform these bombing verifications.

Wu Chunyu said, "This is an all-weather precision-guided bomb that will not be affected by any bad weather. In order to fully verify its performance, I suggest choosing a rainy night. I read the weather forecast and it will rain tonight. .”

Ah!
Many people were shocked!
Is it really so awesome? It's raining and it's night, is it really okay?
When everyone was even more shocked, Wu Chunyu continued, "In addition, there are strict requirements for the height of the bomb, which must be greater than [-] meters, and it is not allowed to be lower than this height."

Are you kidding me!

It's raining, at night, and the height of the bomb must be greater than [-] meters!

Everyone said that they had never seen such a situation, let alone seen it, they had never heard of it, it was too surprising.

A member of the military said a little worriedly, "Mr. Wu, is it okay to drop bombs under such circumstances? What if something goes wrong?"

"Yeah, I think it's better to be on the safe side." Immediately another military person spoke up, "I suggest choosing daytime when the weather is good, and the bombing altitude should start from 3000 meters, or even from 2000 meters. You can start at [-] meters."

Seeing everyone's reactions like this, Wu Chunyu smiled proudly, thinking in his heart, everyone, how unconfident you are in our precision-guided bomb, even if you have a little confidence, you won't be like this.

Wu Chunyu said in a bright voice, "Don't worry, everyone, I think it should be no problem to drop bombs at an altitude of [-] meters even in the night of lightning and thunder."
