Chapter 961 "Pre-production" J-10A

After that week-long technical meeting, the onboard software development work of Ocean No. 1 gradually got on track.

Including Lin Senming's actions, which were exactly the same as Chang Haonan's predictions.

After just a few days, he pulled together a small team from the Fifth Academy of Aerospace Science and Technology that was independent of the Ocean No. 1 project team, responsible for cooperating with the Torch Laboratory to develop multi-phase segmentation technology.

Or strictly speaking, it is preliminary research.

Although China has much more abundant scientific research funding on this timeline, it is 2001 after all, not 2021.

Unless a topic is of great importance, the resources that can be allocated to it are always relatively limited.

Therefore, for a technology like multiphase diagram segmentation that is obviously intended to compete with the future, it is usually promoted in the name of preliminary research, and then when a large project related to it emerges, the opportunity is seized to attach it and formally establish the project.

Although it seems to be just a roundabout way, it can often obtain several times or even an order of magnitude more funding.

And because it involves key projects, the impact of completing the same research content will be completely different.

As for the Torch Laboratory, just as Chang Haonan had promised before, Yao Mengna was sent to carry out the docking.

Over the past two years, Yao Mengna has gradually achieved her goal of "deepening theoretical knowledge" starting from topology.

Although there is still a certain gap between him and cheating players like Chang Haonan and those who are truly trained in theoretical mathematics or theoretical physics.

But as an essentially applied technician, her level is enough to handle most of her work.

Apart from anything else, at least now Chang Haonan can no longer judge the readability of a paper by “even the senior sister can understand it” as he did in the past.

The multi-phase diagram segmentation technology in front of us is exactly at the intersection of mathematical theory and computer application.

It's a good opportunity for Yao Mengna to practice...

Just like that, autumn passes and winter comes.

Time quickly came to December.

As usual, the Aviation Power Group will conduct a year-end work summary at this time of year and plan for the next year's work.

The former was mainly completed by Lin Zuoming and Zhu Linyu.

But the second thing is obviously the task of Chang Haonan, the chief planner.

Fortunately, the overall development route of Aviation Power Group had been determined before the split of the head office in 98, and up to now, the preset time nodes have only been advanced and not postponed.

So all you have to do is take out the pie you drew back then and refine it a little bit.

Chang Haonan had already completed this task in his spare time from scientific research.

Of course, the specific writing and polishing tasks must have been completed by Zhang Liangping.

The content is not complicated either.

The first step is to strive to complete the production and finalization of the WS-10 in the first quarter, and start developing the ship-specific model WS-10H based on it.

The second step is to complete the overall design of the SeA650 engine and implement installation testing.

Third, on the basis of achieving the second point, the research and development of the WS-20 and QC/QD300 series aero-derivative gas turbines will be officially launched before the end of the year.

Considering that the core engines of these two models are both derived from the WS-10, there should not be any extremely difficult obstacles to overcome, at least technically.

What's left are some odds and ends.

For example, starting preliminary research on the fourth-generation turbofan engine.

In fact, logically speaking, developing a new generation of products should be considered a big deal.

At least it shouldn't be classified as miscellaneous.

But the situation of WS-10 is too special.

When the overall design was carried out that year, it was actually planned according to the fourth-generation engine with a thrust-to-weight ratio of 10.

It was only because China was too weak in materials and technology that it was forced to "shrink" into a model with performance roughly equivalent to that of a third-generation and a half aircraft engine.

Therefore, the value of this fourth-generation pre-research is really low and involves almost no real technical work.

The main purpose is to track the current level of basic disciplines in China.

Provide some resources to promote it if necessary.

When the conditions are met and the sealed WS-10 is unsealed, we should be able to produce a fourth-generation engine soon.

Because the workload of this process is so small, Chang Haonan often struggles with whether to give the fourth-generation engine a new model.

It’s better to just call it WS-10G.

In fact, what he really needs to work hard on is the next generation of variable cycle technology.

But that is still a bit far away, at least not something that needs to be considered in 2002...

However, Chang Haonan had everything ready and was just waiting for the annual meeting to be held.

A somewhat sudden, but not unexpected invitation was delivered to his desk.

The J-10A will conduct a pre-production trial assembly ceremony on December 2001, 12.

Although Chang Haonan did not directly participate in the development of Project No. 10, he made great contributions to the development of the J-A sub-model.

Being invited to attend is nothing out of the ordinary.

The only problem was that this day happened to be the day when the Aviation Power Group was originally scheduled to hold its annual summary meeting.

The notice has already been sent out, and it would be bad to postpone it just because Chang Haonan is alone.

So, someone else had to do it.

……

For Chang Haonan, this kind of delivery ceremony is certainly not unfamiliar.

However, this is my first time participating in Chengdu.

Although the weather in Sichuan Province in December was not as cold as Shengjing outside the Great Wall, the damp and cold climate made him, a northerner, feel uncomfortable.

Therefore, before getting off the plane, Chang Haonan put on a military coat.

Fortunately, compared with the first time he came to Chengdu, his private plane can now fly directly to the Huangtianba Airport of Factory 132, saving the trouble of taking a car on the ground.

Of course, on another level, Rongfei Group has made a lot of money from selling the J-7F over the years, so it doesn't have to continue to use those miscellaneous off-road vehicles that seemed to fall apart at any time on the mountain roads.

After getting off the plane, Chang Haonan saw the "Three Musketeers" responsible for the development of the J-10 not far below the gangway -

Xue Chi-kuo, Song Wen-cong and Yang Wei.

Compared to the last time we met, the first two had obviously become much older.

Especially Song Wencong.

When he was called back to take charge of Project No. 10, he was actually already quite old.

By 2001, he was already 71 years old.

In fact, in the second half of the development of the J-10A, Song Wencong had already begun to gradually transfer the command of the project to Yang Wei, the deputy chief designer.

As for the two-seat J-10AS, which is still undergoing flight tests, the latter is directly listed as the chief designer.

The three of them stepped forward and greeted Chang Haonan by either shaking hands or hugging him.

"Let's go over there and have a look."

After a brief greeting, Song Wencong raised his hand and pointed in the direction of the general assembly workshop not far away.

At the entrance of the workshop, parked are the four pre-production J-10A fighter jets that are about to be delivered.

While walking on the road, Song Wencong had already begun to introduce the general situation of this delivery to Chang Haonan.

In fact, even if he didn't introduce it, Chang Haonan would know it.

The situation of this batch of aircraft is slightly different from the "small-scale production" of the J-11B.

The latter is the "small quantity and multiple times" production carried out after the design is finalized in order to speed up the production finalization process and allow the factory to adapt to the production process of the new model.

The main purpose is to quickly improve the process flow and prepare for the subsequent formal mass production.

It is considered as Party A’s behavior.

For the user, the technical status is generally no different from subsequent batches.

However, the "pre-production model" of the J-10A is at an even earlier stage.

It has completed all the tests required for design finalization, but the finalization documents have not yet been officially issued.

This is equivalent to allowing users to use it again to see if there are any problems that have not been discovered during the test flight.

If so, there is one last chance to check for any deficiencies and fill them in before the design is finalized.

For example, on the original timeline, the first pre-production J-10 delivered did not have the ability to use active medium-range missiles, and the landing gear door was also a two-piece type.

It is different from the later mass-produced model.

So it was re-refined and upgraded to a formal and finalized technical state.

Of course, the four J-10A fighters in front of us do not have these problems.

霹雳12已经在上个月由歼8C和歼11B分别进行了靶试，以12发12中的成绩完成定型，首批量产弹甚至已经运抵了空1师1团。

Although the J-10A has not had time to conduct live-fire shooting, its fire control system has undoubtedly been compatible in advance.

As for why "pre-production" is still necessary in this situation, it is obviously just out of caution.

After all, it is the first third-generation aircraft that is 100% self-developed and domestically produced.

It's never wrong to walk steadily.

As they were talking, they had already arrived at the factory gate.

To be honest, although the J-10 upgrade plan was almost entirely initiated by Chang Haonan, the impression left on him by the slim version of the J-10 in his previous life was too deep.

So much so that when standing in front of this plump version of the J-10, Chang Haonan felt a little unreal for a moment.

None of the four aircraft had five-digit serial numbers painted on them, but the tactical numbers 01-04 were spray-painted on the sides of the aircraft in low-visibility gray.

As for the mounts, they were two standard auxiliary fuel tanks for ferry flights.

Due to the huge increase in internal fuel volume and the installation of three nearly parallel weapon racks on the belly, one in front and two in the back, Rongfei directly cancelled the ability to accommodate the third auxiliary fuel tank in this position.

Anyway, there was only a small 800L auxiliary fuel tank in the belly of the aircraft, which would not have much impact on the range.

"These planes are ready to be delivered to..."

Chang Haonan turned around and asked.

Without the machine number, it is impossible to directly determine the unit of the equipment.

Yang Wei pointed to the outermost unit, Unit 04.

Four pilots in flight jackets were currently surrounding an air force officer with the rank of colonel, probably listening to the mission deployment.

"The 44st Regiment of the 131th Air Division is the unit that is used to painting big red eagles on their planes."
