Chapter 1113 Practice No. 7, Independently Determine the Track
Although it is a short break, for these more than a hundred new academicians, the scene in front of them is no different from the ancient times when they were named on the gold list. How could he really sit still?
Therefore, after Academician Lu and several other big guys left to prepare for the subsequent certification process, the scene essentially entered a free discussion stage.
Those who we met in the past should take this opportunity to catch up with each other.
Those who don’t know each other will be considered colleagues in the future after all, and they should always get to know each other.
After all, even if you only look at the second round, there are three to four hundred people who have the chance to be selected in each session.
Unless they are particularly famous or happen to be in the same research direction, it is impossible to be familiar with each other.
Many of the names are even unfamiliar.
Especially for someone like Chang Haonan, who is clearly out of seniority.
Logically speaking, we should take the initiative.
After all, even in terms of physical strength, young people should take a stroll more often.
But most of the time, others know him, but he does not know the other person...
So, in just ten minutes, Chang Haonan had dozens of things in his mind No. new name.
That is to say, my memory is much better after rebirth than before.
Otherwise, this way of recognizing people is basically like picking off the corn, remembering the new and forgetting the old.
It wasn't until a few old acquaintances appeared that he finally had some free time and could return to his seat to rest for a while.
"Academician Song, congratulations!"
Chang Haonan stood up and helped Song Wencong, who was walking over, to sit in the vacant seat next to him.
After the latter sat down, he waved his hands and said in a lowered voice:
"I understand my situation... This year has been so smooth, thanks to you and Xiao Yang..."< br>
In fact, Song Wencong had already started to participate in the selection of academicians of the Academy of Sciences as early as when the J-7III was finalized more than ten years ago.
However, this model cannot be called a success, and the evaluation of the troops is average, and the follow-up has no follow-up.
Of course, those few selections had little hope.
When he presided over the research and development of the J-10 later, he was already relatively old.
Especially in the middle and late stages, it is difficult to keep up with physical conditions, and a lot of the work is actually undertaken by deputy chief engineer Yang Wei.
As for Chang Haonan...
In addition to promoting the J-10 itself, another assistance he provided was actually the establishment of an aviation power group.
Since the "outsiders" after the separation have flourished in all directions, and have even begun to get involved in the research and development of complete aircraft, the threat is too great. The aviation industry system performed amazingly in the two selections in 2001 and 2003. Unity.
It is also an important reason for Song Wenchong's successful election.
Of course, these are internal family matters and cannot be discussed publicly.
So Song Wencong just mentioned it in a vague way, as long as everyone understood it.
As for Chang Haonan...
He has been downplaying the disputes within the system through various methods from the beginning, and it is even less likely to be entangled on this topic at this time:
"I don't know... In what direction will Academician Song continue to develop in the future?"
Song Wencong in the previous life basically entered retirement after serving the basic version of the J-10. Even the J-10S was presided over by Yang Wei developed.
But now that I have put my hat on, I must continue to use my remaining energy.
Otherwise, wouldn’t all the resources invested in you be wasted?
"I am already a 73-year-old man, so why talk about development..."
Song Wenchong and Chang Haonan are two generations apart in age, and they have known each other before, so the former Privately, I don’t care much about the scene:
“It should be a title in a group... As for the specific work, it must be the young people of Xiao Yang’s generation who take the lead...”
The two then chatted about some past events.
But the environment at the symposium obviously did not allow Song Wenchong to "occupy" a celebrity like Chang Haonan for a long time.
Soon, another person walked up to the two of them:
"Academician Chang, congratulations!"
The person had thick short gray hair and high cheekbones. The left and right eyebrows are distinctively not high on one side.
He seems to be about the same age as Song Wencong, but seems to have more energy.
Chang Haonan always felt that he should have seen this person somewhere.
But I really couldn’t remember it for a while.
Fortunately, the other party immediately reported his name:
"Meng Zhizhong, used to be from the Eighth Institute of Aerospace Science and Technology. We had a meeting together at the Aerospace Science and Technology Group before, but we never spoke. …”
"But you should be very familiar with Comrade Guo Liqiang from our unit... I heard him mention you several years ago." In just two or three sentences, the relationship between the two of them was brought closer at the speed of light.
Chang Haonan also had some impressions at this time.
Meng Zhizhong should be the chief engineer of the Fengyun series of meteorological satellites, and an old comrade who has participated in satellite design since Dongfanghong-1.
However, he only thought that the other party came to chat with him, so he still answered in a simple way:
"Yes... Mr. Guo and I have cooperated on both the No. 11 and No. 13 bomb projects, so we are old acquaintances."
Guo Liqiang was the one who was actually responsible for the research and development of the Thunderbolt 11 back then. A deputy chief engineer.
Later, when Chang Haonan developed passive positioning technology, he worked with him to develop a large anti-air/ground-wide projectile based on the huge R33 projectile.
It has now entered the trial installation stage, and together with the Thunderbolt 11/12, it has become one of the main airborne weapons of the J-10 and J-11.
This saves the Chinese Air Force's pitifully rich air-to-ground weapons arsenal, and allows fighter pilots to finally have a second ground-to-ground subject to practice in addition to their ancestral rockets...
< br>
Logically speaking, the two of them are considered acquaintances.
However, the other party had no intention of leaving at all.
On the contrary, the conversation changed:
"I remember... Mr. Chang, after the Qingluan 1 constellation, the next step should be to prepare for communication technology verification on a larger satellite platform?"
Hearing this question, Chang Haonan was immediately stunned.
Then I realized that Academician Meng was probably not just here to chat with me.
But I really have something to talk about.
Song Wencong beside him also found a reason at this time, got up and left.
Although what can be discussed on this occasion will definitely not be anything highly confidential, after all, he is an irrelevant person, so it is better to avoid it.
"Indeed."
After bidding farewell to Academician Song, Chang Haonan nodded:
"The general situation has been submitted for approval, and the specific allocation should be the Shijian No. 7 satellite group."
This matter is in the Aerospace Science and Technology Group It's not a secret inside, and if the other party asks, it's just a foreshadowing.
So there is no need to hide it.
"That's it, Academician Chang... We have a new technology here, and the ground testing is almost complete, so we want to find a satellite platform to carry it..."
Chang Haonan was a little strange when he heard this:
"It's not that I don't want to... but the Shijian No. 7 series is expected to use the Dongfanghong III platform, which is not particularly large in size. We plan to mount it on it There are a lot of channels, and the task load is already very tight..."
"And Academician Meng, logically speaking, the project you are leading should not need to take a ride for verification, right?"
Enter 21? A century later, although China's rocket launch frequency is still not as good as those of traditional aerospace powers, it is much richer than in the past.
In addition, the model he has on hand appears to be a weather satellite, but in fact it is similar to Ocean One, and it is responsible for part of the testing tasks of military remote sensing technology.
Logically speaking, even if the four stars of Fengyun-1 have been launched, he should have the ability to build a separate technology verification star.
"Actually, it cannot be counted as the project at hand...and this task, how should I put it..."
Meng Zhizhong sighed helplessly:
"The load is very heavy It is small and far away from current practical applications, so no matter who comes, they have to find opportunities to hitch a ride... But the structure of the satellite still needs to be modified, and there is no way to put it on a functional satellite..."
It is indeed a bit awkward.
But Chang Haonan became interested instead:
“Tell me more specifically?”
“Academician Chang should know about Beidou, right?”
This question is obviously nonsense, so Meng Zhizhong also Without waiting for Chang Haonan's answer, he continued directly:
"Chief Engineer Fan Benyaofan hopes that when the complete Beidou system is completed in the future, he can achieve it himself and also give other networked satellites independent orbit determination. , The ability to self-calibrate, on the one hand, improves the survivability in extremely special times, and on the other hand, it can also relieve the pressure on ground measurement and control stations..."
"The Shijian-6 that is about to be launched has only two satellites in each group and cannot form a network by itself, so only the Shijian-7 on your side, Academician Chang, can meet the requirements..."
Chang Haonan understood now. .
The so-called "extremely special period" is wartime.
Although the technology to physically destroy satellites is not yet mature, there are many ways to interfere with satellite orbits.
Being able to determine the trajectory independently can be regarded as improving the level of countermeasures.
It will also be of great benefit to the medium and low orbit communication network he hopes to build.
If you want to say support, then I definitely support it.
But Shijian No. 7 must first meet his own requirements after all, so he did not answer immediately, but further confirmed:
“Our satellite group itself needs to change its orbit multiple times, so The fuel of the unified dual-component propulsion system is relatively tight, leaving you with little margin for orbit determination testing..."
Seeing that Chang Haonan did not say anything, Meng Zhizhong immediately expressed his position:
"Don't worry, since we are free riders, we will definitely position ourselves correctly and prioritize our core tasks!"
