Chapter 271
The news about the Qingcheng engine, who does not know up and down the Shudu Institute, the battle made by the establishment of the Southwest Power Machinery Company next door is not small, and the technical staff of the 420 factory at that time lost more than half of it within half a month, and the lawsuit of this matter was directly fought to the ministry.
"Abandon the turbojet 15 and switch to the Qingcheng engine, are you sure that this will ensure the needs of the 10th volley?"
"I'm sure, even if the power system is replaced, the interception plan will not be bad, Southwest Engine got the computer simulation data of the Qingcheng engine from the British side a few days ago, although the high-altitude and high-speed problem has not been completely solved, but it is also a medium level in the military turbofan engine, which is much better than Spey. ”
It seems that the reason is not sufficient, and then added: "And I got the news from there, the engine has now begun bench testing, and it is expected to be on the high-altitude platform in the first half of next year, as long as we insist on doing the high-altitude performance test first, we will definitely be able to get the actual measurement data of the engine at high altitude and high speed next year." ”
As the person in charge of the aircraft propulsion system design office of the Shudu Institute, especially in the case of the aviation industry of the Republic of China with heart disease all the year round, it is even more necessary to spare various schemes, the so-called spare tires, the more the better.
In fact, as early as when the Qingcheng engine project was first launched, it has been targeted by people with a heart, and it is no exaggeration to say that even the South African side that invested in the Qingcheng engine project really wants to say that it understands this engine, in fact, he is far from knowing more than the guy who is ready to eat in Shudu.
After all, if South Africa wants to understand the progress of the project, it still needs Southwest Power Machinery Company to travel a long distance to pass the past, and Shudu is different, this is a building near the water.
"Okay, since it can be determined that the high-altitude and high-speed performance of Qingcheng is better than that of the Spey engine, then our side is not unflexible, anyway, the South African plan has already completed the fuselage design plan, then we will simply take a look, on this basis, only replace the wing of the aircraft, and it just so happens that the design of this wing has already been completed. ”
Since the person in charge of the propulsion system design office in the institute strongly recommended the use of the Qingcheng engine, of course Chief Wen would not object, and he was not too interested in turbojet engines.
There are also overall differences in the propulsion system caused by the difference in the power system between the previous No. 10 interception type and the multi-purpose type, so the part that the team led by Mr. Wen needs to design independently to develop the interception plan is as high as more than 40%.
Now it's different, the interception plan takes a step back, and the Qingcheng engine is chosen as the power system, the difference between the two schemes is only the wing, and the interception plan of the Shudu Institute has been designing the wing for a long time, as early as the Shudu Institute of the Jianjiu period, they have a rich research on the airfoil of the aircraft.
On the contrary, several people in charge of the design of other subsystems of the aircraft scratched their heads, and some people whispered their opinions.
"That.... Mr. Wen, if you follow what you said, if you change a wing to the South African plan that has been designed by Chief Wang Division, the design progress can indeed be completed quickly, but the turbojet 15 is jointly determined by the army and the Ministry of Aviation Industry, and we change it without authorization, I'm afraid it will not be easy to explain to the above, right?"
"That's the case, the reform of our scientific research system is in a critical period, there are a lot of people who have offended up and down, and the pressure is already very great, if you change the design of the new Jianda direction without authorization, I am afraid it will cause a chain reaction!"
The two heads of the departments clearly put forward different opinions one after another, although they have not directly said that they are bad, but this attitude alone is very interesting.
As a project chief engineer, what should I do at this time? How to solve these objections from within the design team is the main problem that a chief aircraft designer has to face in his career.
To solve the problem, we must first understand the root cause of the problem, why it was a good thing to do it, but it was the first to start opposing it within the team.
"Don't be in a hurry to object, this is just a change made by the way because of the emergence of the new power system, it was originally unplanned, as for the turbojet 15 power route we originally took, of course, it can't be stopped, it must continue. ”
For those who hurriedly jumped out to oppose it, it was somewhat understandable that Master Wen continued to add after making the decision that the airframe route with the Turbojet 15 design would not stop.
"Now the fact is that we have suffered engine losses more than once, so I don't care whether it is the turbojet 15 or the Qingcheng engine, as long as they are not completely finalized and produced, we can't easily say that we will give up on another engine. ”
It would certainly be irrational to stop the airframe design based on the turbojet 15 engine because of the slow progress of the engine, and now who can guarantee that the Qingcheng engine, which seems to be leading for the time being, will succeed?
"Mr. Wen is right, now it is not to say to give up Turbojet 15, we don't have this power. Of course, we will not have any reason to stop the turbojet 15, for the research institute of aircraft design, the more domestic aviation engine models are naturally the better, the reason why I proposed the Qingcheng engine, the meaning is just to hope that there can be one more way. ”
The person in charge of the aircraft propulsion system obviously didn't expect that mentioning himself too much would actually lead to the joint opposition of several old colleagues, so he was busy explaining, and then he was afraid that everyone would continue to pull on this issue, he had already achieved his goal anyway, so he turned to the later problems.
Flipping over the sketch of the engine compartment design of the South African design plan on the table, he showed it to the participants: "The use of Qingcheng engine, which is the core power of the final production of the South African plan, but at present, because the engine is still under development, the design of the South African plan is to temporarily use the Spey engine as the prototype power, and we may also face the same problem." ”
The South African program has entered the prototype manufacturing stage, and five new original Spey engines pulled out of the 430 factory have long been shipped to the Kempton Park Aircraft Manufacturing Center, and there are still more than ten units left in China, which is enough for prototype testing.
"According to what I just said, we will be able to finalize the design of the No. 10 Volley using the South African plan to modify the wing design, and send the drawings to Factory 123 for prototype manufacturing before the Lunar New Year, maybe we will be able to see the prototype off the assembly line for testing next year, and the engine at that time will definitely only be able to use Spey. ”
To put it bluntly, before the Qingcheng engine is finalized, any aircraft that uses this engine as the power system can only temporarily use Spey top if it needs flight testing, which is not to say.
However, at this time, everyone actually has no opinion on Spey, compared to the natural test work of using Spey for the first flight of the prototype, the prototype can be seen in 86, which is really shocking, and the progress is so fast that it feels unreal.
"On this issue..... Let's wait to see for the time being, if the design progress is indeed not falling, but we can build a prototype to try, as long as we make an airplane, it is a huge progress, whether it has a chance to fly into the sky or not, at least there is no waste of it, it really doesn't work, let's pull it to do static testing. ”
The aircraft made its first flight at the end of 86, which is certainly not suitable in the opinion of Chief Wen, the No. 10 project is not easy to come by, "stability" presses everything, anyway, there is no need to deliberately catch up with the schedule, it is best to be able to do more tests on the ground stage to ensure that the aircraft can be foolproof when flying in the sky.
In fact, in the original plan, the first flight work was very good as long as it was before 88, and now it is completely unnecessary to advance it to 86.
"In this way, let's wait for the ground test to be done in sufficient detail before the first flight, it will probably be about 87 years, as for what is the progress of the Qingcheng engine at that time, can it be used for our prototype to do flight tests, about these issues, Director Li, do you have any relevant news?"
The chief engineer wants to be safe, and he is not willing to make the first flight in 86, which is nothing, anyway, it is just a suggestion, and it is no problem to postpone it to 87.
As for the progress of the Qingcheng engine, this can be known: "According to the schedule of the southwest engine, next year's Qingcheng engine project will enter the intensive testing stage, if there are no major design defects, it may be possible to complete all the major test work in 87 years, in fact, this project is only on the basis of the mature engine to make improvements." ”
The Qingcheng project has South Africa to give financial support, but it is not bad money, everything is for the schedule, just the prototype of the engine is planned to be manufactured more than 15 units, of which 10 are manufactured in the Rolls-Royce factory, and the other five will be supported by Rolls-Royce, by the Southwest Power Machinery Company to gradually achieve independent production.
Waiting for the Qingcheng engine to be finalized, almost the domestic capacity must also be domestically produced, although the output will not be too high, but to meet the needs of the No. 10 project, it must be no problem.
......
Wang Zhengguo didn't know that Shudu had changed his technical route because of the variable of Qingcheng engine, and he was now staggering to the 607 Institute for inspection, and there were not many things he wanted to know about this unit.
After some tossing, I finally met the person in charge of the research institute, and his appearance gave people the impression that he was a typical chief engineer of the research institute, and he could see at a glance that he was a good man in technology.
It's very simple to introduce, Wang Zhengguo doesn't talk much nonsense, and directly takes out the information in the bag and hands it to the other party.
"I think you will be interested in this thing, I am mainly here for it this time, as for the computer motherboard business of Yaoguang Electronics, although it is equally important, I believe that it can definitely be done with the strength of 607. ”
The information I got in hand is not much, it is only a small part of the many materials of the 2035 radar, the antenna design circuit information of the radar.
Someone has been uncomfortable with himself, he insists on challenging things that do not belong to his ability, and he has taken out the information on the way to study, and the result is that people who have never been motion sickness have actually suffered from motion sickness on this short trip.
A document that allows non-professionals to see that they can stun, and when it really reaches the hands of professionals, the energy that bursts out is absolutely terrifying.
At first, I looked at it disapprerovingly, thinking that it was just some conventional documents, but after I really had to wait until I looked at it twice, and understood what this thing was, I suddenly became demented, my eyes were like light bulbs, and after digesting the information, I closed my eyes and thought carefully about the essence of the design.
It only takes a moment, after confirming the authenticity of this information, and then he is not busy continuing to study the information content brought by the information itself, and quickly flips through this thin piece of information until the last page is determined.
"This is a good thing, it is very important for our radar design research institute, the whole set of radar antenna design drawings, little comrade, you got this information to play a very important role in China's radar industry, rest assured, about the development of the computer motherboard of Yaoguang Electronics, the 607 Institute will go all out, I personally take it as a military project to grasp." ”
According to the original meaning, he actually wanted to get a sum of money from the institute to reward this young comrade, but he couldn't say it when the words came to his mouth, because the current funds of the institute were too tight, otherwise he would not have gone to make civilian products.
When I thought about the introduction when I met just now, I also heard that Wang Zhengguo had a relationship with the subsidiary of Yao Optoelectronics, so I immediately changed my words.
For the military research institute, doing civilian products has never been the main thing, in many cases, the two are completely different treatment, this is any military unit can feel, and now the 607 Institute guarantees to treat the Yaoguang electronic motherboard business with the attitude of military products, and the possibility of success of this project is naturally much greater.
The only thing Wang Zhengguo was worried about before was that Wang Zhengguo of the 607 Institute took out the data of the 2035 radar and negotiated a new radar project, and the 607 side would relax its investment in the computer motherboard business, which must have been a little embarrassing at that time, but fortunately, this worry did not exist.
"Really? Then I must be relieved, as long as the 607 side can go all out to invest technical strength to conquer the motherboard business, I believe that this side of the business can be won, and Yaoguang will be able to breathe a sigh of relief, even if the purpose of my visit this time is half completed." Of course, the computer motherboard is also a very promising market, and the profitability is very considerable, and it will not be a problem to rely on this project to support the entire research institute in the future. ”
I didn't intend to spend too much time on the main board business, and I continued to talk about radar-related issues.
"As for the information on this 2035 radar, in fact, what I see now is only a small part of it, I returned home this time with a complete set of design and production materials, this time for various reasons, so I only brought part of it, if necessary, 607 can get a full set. ”
When these words were spoken, the chief engineer of 607 really didn't know what to answer, after all, it was a full set of 2035 radar, how could this thing be so easy to get hold of? If this is the case, the intelligence personnel and spies of various countries can wash and sleep.
