Chapter 961 "Pre-production" J-10A
After the week-long technical meeting was finalized, the research and development of Ocean One's spaceborne software gradually got on track.
Including Lin Senming's actions, they were completely consistent with Chang Haonan's prediction -
In just a few days, he pulled up an independent independent agency from the Fifth Aerospace Institute. The small-scale team of the Ocean One project team is responsible for the research and development of multi-phase diagram segmentation technology in cooperation with the Torch Laboratory.
Or strictly speaking, it is pre-research.
Although in this timeline, China is already a lot more generous in terms of scientific research funding, after all, it is 2001 and not 2021.
Unless a topic is of great importance, the resources that can be allocated are always relatively limited.
So, for a technology like polyphase image segmentation that is obviously going to compete in the future, the usual practice is to set up a project first and promote it in the name of pre-research, and then wait and see when a big project related to it appears. When the opportunity comes, we will officially 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, Yao Mengna was sent for docking as Chang Haonan promised before.
In the past two years or so, Yao Mengna started from topology and gradually completed her goal of "deepening her theoretical foundation".
Although there is still a certain gap between cheating players like Chang Haonan and those majoring in theoretical mathematics or theoretical physics.
But as an essentially applied technician, her level is sufficient to handle most of her jobs.
If nothing 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 back then.
The polyphase diagram segmentation technology in front of us is right at the interface between mathematical theory and computer applications.
It's just the right time for Yao Mengna to take the opportunity to practice...
Just like that, autumn turns to winter.
Time has quickly entered December.
As usual, the Aerospace Power Group will conduct a year-end work summary at this time of each year and plan the work for the next year.
The former is 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 the Aerospace Power Group has been decided before the split of the head office in 1998, and until now, the preset time nodes have only been advanced, not delayed.
So just take out the cake that you drew and refine it a little bit.
Chang Haonan has already completed this task in his spare time of scientific research.
Of course, Zhang Liangping must have completed the specific writing and polishing tasks.
The content is not complicated.
The first is to strive to complete the production of the turbofan 10 in the first quarter, and to start the development of the ship-specific model turbofan 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 realizing the second item, the research and development of turbofan 20 and QC/QD300 series aeroderivative gas turbines will be officially launched before the end of the year.
Considering that the core machines of these two models are derived from the turbofan 10, there should be no very difficult obstacles to overcome at least technically.
The rest are just bits and pieces.
For example, starting pre-research on the fourth-generation turbofan engine.
In fact, logically speaking, developing a new generation of products should be considered a major event.
At least it should not be classified into miscellaneous items.
But the situation of turbofan 10 is really too special.
When the overall design was carried out that year, it was actually planned according to the fourth-generation engine with a thrust ratio of 10.
Just because Huaxia was too weak in terms of materials and technology, it had to be "shrunk" into a model with performance approximately equal to three and a half generations of aircraft engines.
Therefore, the gold content of this fourth-generation pre-research is really low, and it hardly involves any actual technical work.
It is mainly to track the current level of basic disciplines in China.
Provide some resources to promote if necessary.
When the conditions are met, once the turbofan 10 that was sealed in the past is unsealed, a fourth-generation engine should be available 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.
Let’s just call the turbofan 10G and be done with it.
In fact, what he really needs to work hard on is the next generation of variable cycle technology.
But that is indeed a bit far away, at least it is not an issue that needs to be considered in 2002...
However, everything is ready on Chang Haonan's side, just waiting for the annual meeting to be held.
A slightly sudden, but not unexpected invitation was sent to his desk -
J-10A will be pre-produced on December 15, 2001 Model fitting ceremony.
Although Chang Haonan did not directly participate in the research and development of Project 10, he made the greatest contribution to the development of the J-10A sub-model.
Being invited to attend was perfectly normal.
The only problem is that this day happens to be the day when the Aerospace Power Group was originally scheduled to hold its annual summary meeting.
Even the notice has been sent out, and it is not easy to delay it just because Chang Haonan is alone.
So, someone else had to do it for me.
...For Chang Haonan, this kind of delivery ceremony is of course no longer unfamiliar.
It’s just that this is my first time in Chengdu.
In December in Sichuan Province, although it was not as cold as in Shengjing outside the Guanhai Pass, the cold and humid climate also made him uncomfortable as a northerner.
So, before getting off the plane, Chang Haonan specially put on a military coat.
Fortunately, compared with the first time he came to Chengdu, his special plane can now fly directly to Huangtianba Airport in Factory 132, saving him the trouble of taking a car on the ground.
Of course, from another level, Rongfei Group has made a lot of money by selling the J-7F over the years, and it will not continue to use those no-name off-road vehicles that were eager to fall apart at any time on the mountain road.
After getting off the plane, Chang Haonan immediately saw the "Three Musketeers" responsible for the development of the J-10 not far below the gangway -
Xue Chishou, Song Wenchong and Yang Wei.
Compared to the last time we met, the first two have obviously become much older.
Especially Song Wenchong.
When he was recalled to take charge of Project No. 10, he was already quite old.
By this time in 2001, he was already 71 years old.
In fact, in the second half of the J-10A's development, Song Wencong had begun to gradually transfer command of the project to Yang Wei, who was the deputy chief engineer.
As for the two-seat J-10AS that is still undergoing test flights, the latter is directly named as the chief designer.
The three of them stepped forward and shook hands with Chang Haonan, or greeted Chang Haonan with a hug.
"Let's go over there and have a look."
After a brief greeting, Song Wencong raised his hand to indicate the direction of the assembly workshop not far away -
At the door of the workshop, he was stopping. The four pre-production J-10As 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, Chang Haonan knew it even if he didn't introduce it.
The situation of the current batch of aircraft is slightly different from the "small batch production" of the J-11B.
The latter is a "small quantity and multiple times" production carried out after the design is finalized in order to speed up the production and finalization progress 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 formal mass production later.
It is regarded as a kind of behavior of Party A.
For users, there is generally no difference between the technical status and subsequent batches.
But the "pre-production model" of the J-10A is at a stage further ahead of schedule.
It has completed all the tests required for design finalization, but has not yet officially issued the finalization document.
It is equivalent to letting users use it again to see if there are any problems that have not been discovered during the test flight.
If so, then there is one last chance to check for deficiencies before the design is finalized.
For example, in the original timeline, the first delivery of the pre-production J-10 did not have the ability to use active mid-range bombs, and the landing gear door was also two-piece.
It is different from the actual mass-produced model later.
So it was later reworked and upgraded to the technical state after it was finalized.
Of course, the four J-10As in front of us do not have these problems.
The Thunderbolt 12 has been tested by the J-8C and J-11B respectively last month, and has been finalized with a score of 12 out of 12. The first batch of mass-produced bombs has even arrived at the 1st Regiment of the 1st Air Division. .
Although the J-10A has not yet had time to conduct live-fire target shooting, there is no doubt that the fire control system has been compatible in advance.
As for why "pre-production" is still necessary under such circumstances, it is obviously just out of caution.
After all, it is the first third-generation machine that is 100% self-developed + domestically produced.
You can never go wrong if you walk more cautiously.
While they were talking, several people had already arrived at the door of the factory.
To be honest, although the upgrade plan of the J-10 was almost single-handedly promoted by Chang Haonan, the slim version of the J-10 in his previous life left a really deep impression on him.
So much so that when standing in front of this plump version of the J-10, Chang Haonan felt a little unreal.
None of these four aircraft had five-digit aircraft numbers, but the tactical numbers 01-04 were spray-painted in low-visibility gray on the sides of the aircraft.
As for the mounts, they are two auxiliary fuel tanks that are standard for transition flights——
Due to the huge increase in internal fuel volume, and the installation of one in front, two in back, and a total of three in the belly of the fuselage, It is close to a parallel weapon rack, so Rongfei directly canceled the ability of this position to accommodate the third auxiliary fuel tank.
Anyway, the original 800L small auxiliary fuel tank in the belly of the aircraft would not have much impact on the range.
"These aircraft are 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 Unit 04, the outermost unit.
Four pilots wearing flight jackets are currently surrounding an Air Force officer with the rank of colonel, probably listening to the mission deployment.
"The 131st Regiment of the 44th Air Division is the unit that is used to painting the big red eagle on its aircraft."
