Rule system

Aviation R & D base.

The most west of the Kunlun engine group is used to place a large-scale operation between the properties of the prototype components and debug components.

For a long time, the operation is busy, and various components have been shipped, so that this seems to become a large machinery processing plant, and the person comes to the top, showing an active sight.

Zhang Gangchuan's team is very busy, a few times more busy than last year, because they add new work -

Debug WZ-A2 prototype!

The work of the Kunlun engineer is to debug Kunlun engine, because subsequent perfect use of too many people, some people are separated, or go to the kingstone engine group, or return to the original unit to develop, and so on.

At the meeting of the group company, the Kunlun engine group was debugged by WZ-A2 prototype. Zhang Gangchuan and even the entire team were very excited and expected, but it also faced an embarrassing problem. The people of their team were obvious, Kunlun The perfect work of the engine has entered the later stage, and many technicians have left the team.

The engine group recovers is too difficult. I want to report to the group to make the high-level help. Because there is also WZ-A1 prototype debugging, the Warsk Group has almost no one.

In this case, Zhang Gangchuan simply decided to turn the scattered Kunlun engine prototype team.

Kunlun engine related work is suspended, so that everyone has invested in the assembly of WZ-A1 prototypes, debugging work, first finish the previous work, etc., etc., etc. Go back to their respective positions and continue the original Kunlun engine project.

This is not a decision made by Zhang Gangchuan, but a result of several cores of the team.

The Kunlun engine group also reported to the group company.

The high-rise of the aviation group has no opinions on this, even appreciate the 'decisive' of the Kunlun engine group, and has seen the report of the WZ series engine. The high-level engine has not been able to see the Kunlun engine.

Kunlun engine?

One is always a problem, the performance of the engine still can't keep up with the meaning of continuing debugging?

The WZ series engine is just a low-oriented version of WZ-A2, design and performance. It is fully able to catch up with the international advanced level. Even if it cost more manpower, it is even time, just put the engine, Everything is worth it.

With the high-level support of the Aviation Group, the Kunlun engine unit also focuses on WZ-A2 assembly and commissioning work.

Their progress is faster than WZ-A1, because WZ-A2 is a low-oriented version, some parts are also ordinary, and there is basically no big problem during the manufacturing process, plus directly aiming J-20 fighter, The time is earlier, and they have completed the WZ-A2 prototype assembly.

After the first prototype assembly of WZ-A2, the Kunlun engine unit immediately conducted a test.

As a result, failure!

No engine running!

Kunlun engine block now being amended to make the first run problems occur, they can easily identify several major problems.

For example, some narrow pipeline.

For example, the control system there is a small problem, no amount of feedback much oil.

For example, there is a supercharger blades are not running.

and many more.

These are used over two weeks repeated tests concluded.

Now they are busy to fix the problem and re-testing parts of problems.

Zhang Gangchuan touches rare free moment, he stood on the second floor of the aisle top among the entire operation, with a smile on his face, exclaimed, "Now Bi Kunlun is much faster. Two weeks to solve several major problems . "

Next week is the head of Kai power sector.

"Yes!"

Zhou Kai put his hand on the railing, think back and said, "I had no experience. I remember a long time, about two or three months more than it is now only half a month, to resolve all also does not take a month. "

The first test fails entirely to be expected.

Engine just assembled for the first time commissioning will certainly fail, even if only during the installation process, may also be a problem, not to mention the parts of a problem because of improper operation.

For example, there is a supercharger blades are not running, the installation may be a problem, perhaps its own weight problem.

Both are possible.

It's not that they can finish complete control.

Zhang Gangchuan also very pleased with the progress of work, he suddenly said, "I heard Zhao Yuanshi there began. Really very fast, did not think ah!" Then also with a sigh and shook his head.

It was really sigh!

When assigned to the commissioning of the WZ-A2, Zhang Gangchuan feel Airlines Group is to take care of their own team, after all, they are the group of 'old team', also has a wealth of experience.

The Zhao Wei team originally designed, WZ-A1, can be said to be a top version, aiming to the top J-31, but J-31 design drawings are not completed, engine sample manufacturing, debugging work, also equal It was delayed.

Zhang Gangchuan believes that it is a high level of the group.

The WZ series engine is very high, but too high-end is not necessarily a good thing, such as manufacturing, commissioning will encounter more problems, low-distribution version of WZ-A2 can debug success, then make WZ-A1 prototypes to do debugging The work arrangement is more reasonable, and progress will definitely be faster.

Of course.

These are not straightforward.

Anyway, Zhang Gangchuan is so understanding, but he didn't think of it at all, Zhao Wei can stop the work of the aircraft design, and also took out a stunning design of the high-rise, military-party.

He did not participate in the meeting, didn't know how advanced the Wars-1, but seeing the support of the Group's high-level follow-up to WZ-A1, and also knows that it is completely changed.

However, Zhang Gangchuan still believes that WZ-A2 prototypes are more important and the core work.

Even if it is a stunning fighter design, it is just a design, I don't know how long it takes, and even says that most of the high-end design will only stay on the paper because of various reasons.

WZ-A1 engine is also too high, a lot of designs, the demand is too high, even in front of 'Patchwork' out of components, the overall binding is assembled into an engine, and the debugging will also have a lot of problems, and even some can't solve it. problem.

WZ-A2 engine is different.

Because of the design of a lot of demand high-end design, WZ-A2 and WZ-A1 differences are very different, which is not far from the design of manufacturing capabilities, naturally do not have a big problem such as' unable to manufacture.

WZ-A2 engine debugging can be assembled to the J-20 fighter, even if it is assembled to J-15 again, it is enough to support the group company to continue to invest, let WZ-A2 engine strive for mass production.

WZ-A2 engine, the prospect is broad!

WZ-A1 ...

"You said, how long can they achieve the first test flight?" Zhang Gangchuan thought about asking Zhou.

Zhou Kai smiled and said, "I think? Three years, four years? Maybe it can't do. Still very far, our Kunlun used two years, 'So high-end ...", he suddenly thinks Saying death, turning, "However, Zhao's abilities are really strong, maybe some difficulties can overcome."

"So, three years? If you can go in that step in three years, it is really very powerful. The design is really not thinking!"

"But it can be faster, for example, our first stage debugging is completed, take a group of past ..."

Zhang Gangchuan listened to nodded and continued to ask, "What about us?"

"It's enough for a year!"

Zhou Toyo is very confident. "We have experience, just some shortcomings, after all, the WZ series is not we designed."

Zhang Gangchuan nodded, "Not our design, but said debugging engine, we are the most professional. One year ... I think it can be shorter, maybe it can be done ten months?"

"Hope, anyway, try our best!"

"Tryard!"

......

When the Kunlun engine group put into WZ-A1 prototype debugging, the WZ-A1 of the Battle Eagle engine group was also assembled.

WZ-A1's assembly time is slower than an estimate.

The reason is Zhao Wei.

Zhao Wei's plan is that after the prototype is complete, then the factory is involved in the debugging work. Later, because of the "Forbes" broke the property, it is always familiar with people, and a lot of trouble is found, he simply in advance Come to the factory here.

After waiting, he found that the early quite is correct.

During the assembly process of the prototype, Zhao Wei discovered a lot of problems, such as the first combustion room sent, the narrow and small oil manufacturing, the difference is not so big, the naked eye is very ugly, but make a lose Oil test, the gap after a period of time is immediately out.

This is not a big problem.

Zhao Wei discovered the biggest problem, the problem of two turbine blades, because the turbine blade is a whole piece of direct formation, the intensive hole in the blade, is easy to make the blade quality problem, the factory inspection It is impossible to be so fine, and it is easy to send a part of the parts that are sent, and it is easy to change two turbo leaves.

Although most of the discovery is a small problem, the small problem is concentrated together, it is also enough to assemble the prototype, start testing directly.

Wait until the problems of each component, there is still a lot of problems in the assembled engine, and there is still a lot of problems, mostly the coordination of each component, because the manufacturing parts and the original design have gaps, and the gaps of each component are each. Different, there is also a coordination problem. .

When the sample has been assembled, when I started testing, Zhao Wei turned around the engine and suddenly said, "demolished the compressor."

"what?"

Several engineers around them were stunned.

Zhao Wei continued, "I will let you take it."

Others don't know what is going on, but the engineers still feel that the compressor is removed. After the unpacking, they will arrive in the afternoon, and the debugging in the morning will not be yet.

After the compressor is removed, Zhao Wei let people remove a booster blade and use a good raw metal material that melts, block the hole inside the vane, and then carefully polished it, only reinstall it to the engine.

This is not understanding.

Zhao Wei explained that "I thought about it, the performance index of the compressor was too high, perhaps the pressure of the air-free wellway. If it is high in power, there is a risk of burying."

"Explosion, so serious?"

The bursting is also the pressure in the inside, directly open the air supply valve, let the high pressure, high heat air, in a large number of pores, will directly cause damage to the hole.

If it is serious, high-pressure, high-heat punching back to the front end of the engine, causing damage to the entire engine.

This thing is too serious.

Zhao Wei must be in advance, otherwise it will certainly affect the debugging schedule, and even more casualties.

The compressor replaces the blade for a day, and then reinstalls the third day.

All people are around.

When the operation test is about to begin, Zhao Wei once again walked to the engine, and turned a few laps around the engine, and made many people hang, and he happened to hear any problems, and then dismantled the engine ...

It is good to do it like Zhao Wei.

He waved his hands in the distant people, and he walked immediately, leaving only an engineering personnel in place, and opened his mouth, "Start!"

"call!"

Someone presents in the field shouted.

"Test start!"

"Prepare!"

"ignition!"

The engine's operation test is not so complex, but most people are far from, the engineers control the problem of being placed in a suitable problem, and utilize high-voltage fan simulates the wind of fast flight, and then controls the official ignition in the distance.

"Boom! Boom! Boom!"

The noise of the aviation engine is avoidable, huge noise suddenly floods all spaces.

The people around you hear the 'bang, the rock, but it becomes more excited, because continuous bangs also represent, the engine is in normal operation, and there is no problem.

After the engine is officially launched, you can only see the flame ejected, the sound is constantly continuous, but the decibel of the sound has a significant decrease, indicating that the engine preheating, and enters the process of normal operation.

Some people caught the palm.

Soon all people have a palm, and everyone is excited about the face, because the scene in front is proud.

This is the first test!

Most engine first test, it is already very high, WZ-A1 is a very high-end engine. It used to exist only in imagination. It can start the first test, and can start and run normal. It's hard to believe that it is said that the beginning is half the success, and they are more expected to complete debugging.

The engine plan is over an hour or so, and it will strive to rush to the highest power.

This is a difficult relationship.

When rushing to the highest power, the engine is likely to fail.

In this regard, the people of Yuan Haitao have a speech. They have participated in the test of Kunlun engine. Do not say that the first test of the first machine, the second machine moved to the power engineering laboratory, did not solve the highest power. When there is a problem, when the second machine test is tested, it simply does not do the highest power test to prevent serious accidents.

When the engine is running for a while, everyone looked at Zhao Wei standing in the middle.

Zhao Wei waved his hand, "started the highest power!"

Everyone's heart followed.

"boom!"

As engineers adjusted wind speed and oil control, the engine suddenly made a huge bang sound, and the bangs continued to have a minute.

Zhao Wei commanded, "Yes."

Engineers immediately dropped the parameters, and the ribs of the engine also slowed down slowly.

The next step is the 'high deceleration' test.

The 'high deceleration' test is a rapid reduction in the analog fighter. The design of WZ-A1 is almost stopped, and the high pressure gas in the compressor passes the hole, released to the jet port to form a certain power while ensuring the aircraft components. Normal operation.

The advantage of this way is the 'savvy fuel', in addition, the mainvation of the main jet does not have the maximum achievement, and it can improve the flexibility of the fighter.

The 'high deceleration' test is not afraid of what is the big problem, mainly in the test process, get the parameters of the engine operation.

This is true for several items.

Let the engine simulation air operation, test the thrust of the engine, the temperature, etc. of each component, while recording data such as oil supply velocity, wind speed.

These data are to test what they want.

The process of engine completion is to let data, strive to achieve the most complete balance point, but also need to adjust the performance of the components, and strive to make them more coordinated.

Of course.

This is the case where the engine has no big problem.

If a test link, the engine has turned off, or the thrust is abnormally lowered, and the increase is not only coordinated, but also solves the problem.

The Kunlun engine is slow, because there is always a big problem, every big problem comes out, and the light is to argue, and it takes a long time.

Half an hour has passed.

When the last test ends, Zhao Wei also decisively directed that "it will be here!"

The engineers responsible for control immediately stopped oil, the engine was running for a period of time, and the sound was gradually stopped.

Zhao Wei looked around and took a smile.

"~~"

Everyone immediately followed the palm, and it was also excited to discuss it. "This is the first test, too perfect!"

"Didn't see any problems!"

"When I go to the highest power, my heart feels that I have to squat out, I am afraid to fall out ..."

"Swipe! Don't say this!"

"Anyway, it is very successful!"

"I used to stay in Kunlun, I have participated in several tests. Every time I can find a problem. I feel that this kind of prototype that is just assembled is also perfect than Kunlun No.3."

"I really can't imagine!"

"The first test is so successful, our work is also very fast? How long can you get the test flight?"

"Three months?"

"No! It's enough for two months!"

"I have said that the Kunlun engine line is three machines, there is no improvement, when the Kunlun is three machines, it has been completed in the test flight ..."

"So I think it can be applied for testing machine now!"
