Chapter 1113 Practice No. 7, Autonomous Orbit Determination

Although it was said to be a short break, for these more than a hundred new academicians, the scene in front of them was no different from the ancient gold list. How could they 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 have known each other in the past should take this opportunity to catch up with each other.

Those who don’t know each other will be considered colleagues after all in the future, 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 there are some particularly famous ones, or those who 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 someone like Chang Haonan, who is obviously inferior in seniority.

Logically speaking, we should take the initiative.

After all, even in terms of physical strength, young people should be strolling around more.

But most of the time, others know him, but he doesn't know the other person...

As a result, in just ten minutes, dozens of new names appeared in Chang Haonan's mind.

In other words, the memory after rebirth is much better 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 as he spoke, 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 low voice:

"I understand my situation... It's all thanks to you and Xiao Yang that this year has been so smooth..."

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 is even less successful.

Naturally, those few selections had little hope.

Later, when he was in charge of the research and development of the J-10, 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 even started to get involved in the research and development of complete aircraft, the threat is too great. The aviation industry system showed amazing unity in the two selections in 2001 and 2003.

It was 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 knew it.

As for Chang Haonan...

He has been downplaying the disputes within the system through various means from the beginning, and it is even more impossible to dwell on this topic at this time:

"I don't know...in what direction will Academician Song continue to develop?"

Song Wenchong in his previous life basically entered retirement after the basic version of the J-10 entered service. Even the J-10S was developed under the leadership of Yang Wei.

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 73 years old, so why should I talk about development..."

Song Wenchong and Chang Haonan are two generations apart in age, and even if they knew each other before, the former doesn't care much about the scene in private:

"It should be a title within 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.

However, the environment at the symposium obviously did not allow Song Wenchong to "occupy" a celebrity like Chang Haonan for a long time.

Soon, someone else walked up to the two of them:

"Academician Chang, congratulations!"

The person had thick short gray hair, very high cheekbones, and distinctive eyebrows that were not high on either 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 Aerospace Academy. We had a meeting together at the Aerospace Science and Technology Group before, but we never talked..."

"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 was brought closer at the speed of light.

Chang Haonan also had some impression at this time.

Meng Zhizhong should be the chief engineer of the Fengyun series of meteorological satellites, and an old comrade who has been involved 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 collaborated on the No. 11 and No. 13 bomb projects. We are old acquaintances."

Guo Liqiang was the deputy chief engineer who was actually responsible for the research and development tasks of 霹雳11.

Later, when Chang Haonan developed passive positioning technology, he worked with him to modify a large anti-air/ground-type 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.

It saved the pitifully rich air-to-ground weapons arsenal of the Chinese Air Force, and finally gave fighter pilots a second ground-to-ground subject to practice besides the ancestral rockets...

In theory, the two of them were acquainted.

However, the other party had no intention of leaving.

Instead, he changed the subject:

"I remember... After the Qingluan No. 1 constellation, Mr. Chang's next step should be to prepare for communication technology verification on a larger satellite platform?"

Hearing this question, Chang Haonan was stunned.

Then he realized that this Academician Meng was probably not just here to chat.

But he really had something to talk about.

Song Wencong, who was standing next to him, also found a reason and stood up to leave.

Although what can be discussed on this occasion is definitely not something highly confidential, he is an irrelevant person after all, so it is better to avoid it.

"Indeed."

After saying goodbye to Academician Song, Chang Haonan nodded:

"The general situation has been reported for approval, and the specific allocation should be the Practice No. 7 satellite group."

This matter is not a secret within the Aerospace Science and Technology Group, and the other party's question is just a prelude.

So there is no need to hide it.

"It's like this, Academician Chang... We have a new technology here, and now the ground test has been done, so we want to find a satellite platform to carry it..."

Chang Haonan was a little surprised when he heard this:

"It's not that I don't want to... But the Practice 7 series is expected to use the Dongfanghong 3 platform, which is not particularly large in size. We plan to carry a large number of channels on it, and the mission payload is already very tight..."

"And Academician Meng, logically speaking, the project you lead should not need to be verified by piggybacking, right?"

After entering the 21st century, although China's rocket launch frequency is still not as high as those of traditional aerospace powers, it is also much richer than in the past.

In addition, the model he has on hand is a meteorological satellite on the surface, but in fact it is similar to the Ocean No. 1, and it undertakes some testing tasks for military remote sensing technology.

Logically speaking, even if the four satellites of Fengyun No. 1 have been launched, he should have the ability to independently develop a technology verification satellite.

"It's not really my current project... and how should I describe this mission..."

Meng Zhizhong sighed helplessly:

"The payload is very small, and it's still far from the current practical application, so no matter who comes, they have to find an opportunity to hitchhike... but it just happens that the satellite structure needs to be modified, and it can't be placed on the functional satellite..."

It's a bit awkward.

But Chang Haonan became interested:

"Can you tell me more?"

"Academician Chang should know Beidou, right?"

This question is obviously nonsense, so Meng Zhizhong didn't wait for Chang Haonan to answer, and continued directly:

"Chief Engineer Fan Benyao hopes that when the complete Beidou system is built in the future, it can be realized by itself, and at the same time, it can also give other networked satellites the ability to autonomously determine orbits and autonomously calibrate. On the one hand, it can improve the survivability in extremely special periods, and on the other hand, it can also relieve the pressure on ground tracking and control stations..."

"The Practice 6, which is about to be launched, has only two satellites per group, and it cannot form a network by itself, so only the Practice 7 on your side, Academician Chang, meets the requirements..."

Chang Haonan understood now.

The so-called "extremely special period" is wartime.

Although the technology of physically destroying satellites is not yet mature, there are many ways to interfere with satellite orbits.

Being able to determine orbits autonomously can also be regarded as improving the level of countermeasures.

It is also of great benefit to the medium and low orbit communication network he hopes to build.

If you want to say support, then it is definitely support.

But Practice No. 7 must first meet its own requirements, so he did not answer immediately, but further confirmed:

"Our satellite group itself needs to change orbits many times, so the fuel of the unified bicomponent propulsion system is relatively tight, and the margin left for you to do orbit determination tests... I'm afraid it won't be much."

Seeing that Chang Haonan did not say it firmly, Meng Zhizhong immediately expressed his position:

"Don't worry, since we are hitchhiking, we will definitely put ourselves in the right position and give priority to core tasks!"
