Movie black technology

After reading the chip samples, Tang Huacong also brought a report.

"The above is our current project progress. Now the key projects have all completed sample manufacturing and testing, and the remaining non-essential projects have also reached 30% completion."

Chen Shen picked up the file and opened it. The items on it were roughly divided into three categories according to process materials and special devices, like a replica of system materials.

Most of the key projects are concentrated on special devices such as aerospace chips. Even if other processes and materials cannot be completed for a while, they can wait slowly. But without these special devices, the entire spacecraft will basically be on the ground.

Chen Shen roughly flipped through it, and soon came to the part of special equipment.

Tang Huacong watched from the side, showing heartache involuntarily.

When the production of a necessity is low enough, even a paper towel can fetch sky-high prices.

The same principle applies to these special devices.

Because these devices are only supplied to one Tibetan Antelope, the production quantity basically does not exceed 500 pieces, and the process and technology used are still different from the current ones. Some factories even spend a lot of money to upgrade their production lines in a targeted manner. to meet manufacturing requirements.

Or simply call similar domestic production lines for production.

For example, if you want to manufacture aerospace-grade chips, you need to use the current carbon-based chip production line. Judging from the current production schedule of China's chips, the price required for just one call is at least over 100 million.

Moreover, among these special devices, the production volume of chips is quite large, and hundreds of thousands of them can be produced at a time, and many can be reserved for future use, or used for other projects.

But except for chips, the production volume of most of the structural components that can only be used on the Tibetan Antelope is really bleak, coupled with the extremely fast delivery time required, the end result is that their cost is extremely high, and some The purchase price of the components is higher than the price of the goats eaten by the soldiers on the opposite side.

If calculated according to the market price, in order to produce these components, various systems across the country have spent more than tens of billions in upgrading production lines, labor costs and other aspects.

According to Tang Huacong's experience, if it is an ordinary project, the funding pool would have been drained by this bottomless pit long ago, but there is no sign of this on the Tibetan Antelope, and he seems to have never heard of the Tibetan Antelope from the beginning to the end. The total cost of the project...

Chen Shen flipped through the entire report, turned back to the front, and ticked off a few unremarkable craft materials.

"The projects that have been completed are enough for the first generation of Tibetan antelope, but they are still far behind the technology required by the second generation of Tibetan antelope, so these projects are the focus of the next work."

Tang Huacong came over to take a look, and immediately found that these pointed items were all related to heat dissipation.

Either new heat dissipation materials and heat sinks, or the construction of a new heat dissipation system.

"These materials and systems are a bit beyond the specifications of our Tibetan Antelope?" He took off his glasses, rubbed his eyes, and asked casually.

In space, because there is no air as a heat dissipation medium, if the spacecraft or satellite is not equipped with a heat dissipation system, whether it is the heat brought by the sun's rays or the heat brought by the operation of the device, it will slowly accumulate in the system and cannot be dissipated in large quantities, resulting in a higher temperature. And higher and higher until the system fails.

Therefore, whether it is a space station or a spacecraft satellite, it has its own set of heat dissipation systems, usually through the heat sink, the internal cooling system brings heat to the heat sink, and then the heat sink dissipates the heat through thermal radiation.

In layman's terms, the heat dissipation method of the radiator is somewhat similar to that of the radiators that people use every day, but the use environment has been changed, from indoors to space, and the function has changed from heating to heat dissipation.

This heat dissipation method is the most widely used. Those white strips outside the space station that look like solar panels are heat sinks.

Regarding Tang Huacong's question, Chen Shen shook his head: "The current heat dissipation specifications are sufficient for the first-generation Tibetan antelope, but it is far from enough for the second-generation Tibetan antelope."

The heat dissipation system currently used by the Tibetan Antelope is a place where he was lazy.

While the scale and structure of the heat dissipation system remained unchanged, he replaced the heat dissipation materials inside with those that can be directly produced now.

The most direct reason for this is that the Tibetan Antelope is now electric, and will not generate huge internal heat like nuclear power.

It is the same as the current spacecraft and satellites, as long as it can withstand the heat brought by the sun's rays, it is enough, so it will not be a problem to lower the cooling system by a few levels.

But if you want to put the current cooling system on the nuclear-powered Tibetan Antelope, it will probably explode on the spot when it is turned on, even if it is useless on the earth...

Tang Huacong still didn't understand, "Isn't the second generation of the Tibetan Antelope too far away? We haven't even taken off the first generation..."

He looked at Chen Shen, very suspicious of the second-generation Tibetan antelope he was talking about.

This is not without reason.

He had seen a saying on the Internet before: "Chen Shen can't count second."

The reason is that looking at all his inventions from the boxer to the present, it seems that no second-generation version has been born...

Not to mention big things like the Crimson Storm and the Boxer.

But whether it is Nezha Kuafu, or Bai Ze AI, or photoacoustic detection...

It is true that there has never been a second-generation version of these things, and Chen Shen has consistently researched them and then thrown them aside, or handed them over to the tool people to continue researching. He directly started a new project by himself, without any intention of continuing to study.

This kind of thing happened so often, and the saying that Chen Shen can't be counted on the outside has been spread.

So can the Tibetan Antelope really break the law of "number two" as Chen Shen said, and the second generation of Tibetan antelopes will appear?

Tang Huacong couldn't help being suspicious.

If Chen Shen knew what Tang Huacong was thinking now, he would definitely argue: "These technologies are just too early, as long as we wait a few more years, the tool people will naturally be able to research the second generation, saying that he can't count two, count two Is it difficult? One, three, four, five, six, seven..."

It’s just that he didn’t know, so he replied normally: “If there are no accidents, the second generation Tibetan antelope can start preparations after the first generation Tibetan antelope makes its first flight.”

Chen Shen folded his chest, thinking back to the technical demonstration meeting on micro-nuclear reactors held in these days, he was a little nervous.

Fortunately, these efforts have paid off. Judging from the current situation, as long as the first flight of the Tibetan Antelope is successful, there should be no problem with the project passing the review.

A nuclear reactor that flies in the sky is not the same as a nuclear reactor that can fly in space.

The former is called a flying pollution source, and the latter is called the hope of mankind.
