Five o'clock in the morning.

Harbin International Airport.

A bright silver flight slowly lands on the runway, gliding along the leveled runway.

Looking at the city shrouded in morning mist outside the cabin, Lu Zhou suddenly spoke.

"It's the first time I've been to this north."

Casting his eyes out the window, Wang Peng said.

"It's the second time I've come."

"Oh?"

"The last time was about six years ago, when I was on a mission to the border, and I passed by here on the way, and I stayed here for about a day and a half."

"There's a mission to the north too?"

"It's all in the south, south, and west."

Lu Zhou nodded, but didn't ask what the specific task was.

First, after asking, it is estimated that Wang Peng will not say, and secondly, he has little interest in understanding this kind of thing that is not the same world as him.

After getting off the plane, a silver Buick stopped at the door, and a very low-key man got out of the car and opened the door for Lu Zhou, sending them to a hotel near Harbin Institute of Technology.

This time, the driver was not Wang Peng, but someone sent by the Science and Industry Bureau.

Unlike the last meeting held in Beijing, the participants at this aerospace engineering bidding conference were relatively high-status, or rather sensitive.

And because of the content discussed at the meeting, there may be some things that cannot be disclosed to the outside world for the time being, so whether it is the identity of the participants or the time and place of the meeting, it is strictly confidential to the outside world.

Even, even Lu Zhou came here for a meeting, nominally to attend an academic lecture at Harbin Institute of Technology.

After getting out of the car at the door of the hotel, two men waiting at the door greeted him.

The man at the head smiled, and stretched out his right hand from afar.

"Professor Lu, long time no see!"

Holding his right hand and shaking it, Lu Zhou smiled and said.

"Fortunately, Director Li."

After letting go of his hand, Director Li looked at the old man standing next to him, raised his right hand slightly and continued to introduce.

"Please allow me to introduce that this is the president of Harbin Institute of Technology, Academician Zou Yu."

"Fortunately."

"I'm fortunate to have a meeting here," holding Lu Zhou's outstretched right hand and shaking it, Academician Zou said with a smile, "I used to hear that Professor Lu was young and promising, but today I saw it really extraordinary!" ”

"It's over."

Director Li smiled and said, "Okay, let's not be polite, you got off the plane so early and didn't have time to have breakfast, right?" It just so happens that the two of us also have our stomachs, why don't we go to the hotel for something to eat first? ”

The group quickly reached a consensus.

Especially Lu Zhou, who was on the plane last night and didn't sleep well.

By this time, I was already hungry.

Arrived at the hotel and breakfast was ready.

A bowl of steaming mutton soup came first, followed by a roast cake wrapped in meat cubes, which was simple and simple, but unexpectedly delicious. Especially the bowl of mutton soup, Lu Zhou just took a sip, and he felt that the cold air in his whole body was dispelled, even in this northern city that had already entered winter early, he didn't feel cold.

The people sitting at the table ate and chatted, and soon talked about academic matters.

In the chat, Lu Zhou learned that this academician Zou is researching the two directions of ceramic composite materials and biocomposite materials in materials science, and he is a big star in this field. When he heard him talk about biocomposite materials, Lu Zhou, who thought of something, moved slightly in his heart and asked.

"Biocomposites?" Lu Zhou's heart moved slightly, and he asked with a smile, "I don't know which part Academician Zou is studying?" ”

Academician Zou smiled and said, "Me? I'm mainly engaged in HA/Ti. ”

Hydroxyapatite and titanium composites?

Hearing Academician Zou's answer, Lu Zhou's face couldn't help but show a look of interest.

Although he didn't study it carefully, he still knew something.

As one of the more cutting-edge research directions in the field of materials science, hydroxyapatite and titanium composites are generally optimistic about artificial bone materials in the new century. If this technology breaks through, it will have a huge impact on industries such as medical and bionic machinery.

"We are now working with Aurora University to develop a biomimetic artificial bone that can replace human bone and can be controlled by nerve electrical signals, and if this technology is successful, it may completely solve the problem of limb amputation."

Lu Zhou: "Controlling machinery through neural electrical signals? I'm afraid it's not easy. ”

Academician Zou nodded: "As worthy of Professor Lu, I saw the key to the problem at a glance." In fact, the biggest problem we face now is the collection and feedback of neural signals. Especially in the area of feedback, it is not easy to simulate neural signals to deceive the brain. ”

"It sounds like a lot of fun."

Although Lu Zhou's mind at this time was not bionic, but something else.

Academician Zou smiled and said, "It's quite interesting. If Professor Lu is interested, please come and visit our laboratory, and I can take you around. ”

Lu Zhou: "Wait until the bidding conference for this lunar landing project is over, and then it will be troublesome for Academician Zou." ”

Academician Zou said in a joking tone: "Don't bother, if it can arouse your interest, maybe it can help us a lot at that time." ”

When a problem cannot be solved, the easiest way is to get Professor Lu interested in it.

This phrase was originally only circulated in the mathematical community, but now it is no longer the prerogative of the mathematical community......

……

Early November.

The Lunar Landing Project Bidding Conference was held in a low-key manner in the auditorium of Harbin Institute of Technology.

After showing the barcoded invitation letter and ID card to the staff at the door, Lu Zhou handed over the communication equipment, and then walked into the venue with the footsteps of the reception staff and took a seat at the position with the identification sticker.

In addition to the checks at the time of entry, there is also a surprise check fifteen minutes before the start of the meeting, which is mainly to check for missing communication equipment, in addition to checking identity information.

After all the work was done, it was about ten o'clock in the morning.

After a staff member of the Bureau of Science and Industry came to the stage to read out the confidential matters, a leader of the Bureau of Science and Industry soon announced the beginning of the bidding meeting.

This bidding conference is different from the bidding conference of other projects, after the meeting is not by the tenderer to explain the specific requirements of the project, but by the bidder to show the technology described in their own bidding materials.

Of course, this display is in the form of PPT, except for some more sensitive data, and will not involve the specific technical core.

In fact, the strength of the two domestic aerospace giants is indeed good, although there is still a certain gap with the world's top level, but it still shows a lot of eye-catching technologies.

For example, the 500-ton liquid oxygen kerosene engine offered by the aerospace group.

Although only the technical demonstration was carried out on the PPT, according to the speeches of the experts appointed by the aerospace group, the high-power turbine pump, high-flow gas generator, high-pressure and high-flow cryogenic valve, and high-precision flow regulator of this engine have been developed, and the samples used to test the performance have also been completed and are currently in the testing stage.

On the other hand, Hangke Group did not show weakness, showing the latest high-temperature and wear-resistant ceramic coating technology, which solved the key technical problems of liquid oxygen and kerosene dynamic sealing under high-speed and heavy-load conditions. This technology can be applied to the sealing ring on the end face of the turbine pump of the 120-ton liquid oxygen kerosene high-pressure refueling engine, which can effectively improve the performance and safety of the rocket engine, and it is also a fairly advanced technology.

Finally, after the technical director of Hangke Group completed the technology demonstration, it was finally the turn of Star Technology.

At the suggestion of the host of the meeting, Lu Zhou walked to the stage and released the PPT prepared a week ago, showing the latest electric propulsion system developed by Star Technology.

And almost at the moment when the PPT was put on the second page.

The entire auditorium was eerily quiet......
