I ask you to build tractors, but you build rockets?

In the end, driven by Lin Ju's aroused curiosity, the CS75 not only completed a lap around the entire base, but even drove for a certain distance on the road outside the base despite the objections of the engineers, with a top speed of nearly 100 kilometers per hour.

Many employees at work thought this car was the work of Xinan's intelligent driving department, leaving the latter confused.

When it got dark, Lin Ju was sent back to the base by SC09 and jumped out of the car. He felt the wiring harness outside the vehicle and couldn't help but sigh:

The output of X32035 is too low. The average daily output is 120 pieces. It takes eight pieces to run SC09. Even if it is reduced to four pieces, it can only supply 30 cars. It can only meet the demand of 10,000 cars by supplying all cars in one year. It is too little.

And this is impossible. Spacecraft and internal needs are greater. X32035 supports supercomputing and has the potential for deep AI learning. It is completely unfeasible to use it for the automotive industry.

Another point is that the cost of automatic production lines is very high. The average production cost of this batch of X32035 is 35,000 yuan per piece. This cost is negligible for aerospace use, but it is not feasible for civilian use.

Therefore, we still have to design silicon wafer versions of ternary chips and components ourselves, and have them manufactured by chip companies, which can both reduce prices and greatly increase production.

However, the Microelectronics Department of the Electronic Devices Department is already working hard on this, especially with the acquisition of X32035 that can carry out substantial ternary compilation and design, the progress will definitely be rapid.

…

In Liangshan Prefecture Autonomous Region, He Zhuang and a few people greeted several special "passengers" outside the train station.

More than half an hour after the train arrived, the docking staff from Xinyuan walked up to them with two oversized metal-cased suitcases.

Here are two rocket-launched rocket recovery control systems, which have been programmed based on the data of YF100K and Long March 6 and sent directly to the Sechang Satellite Launch Center.

The Long March 6 Yaosan rocket, which has been delayed again, will be equipped with one of two customized control systems worth 20 million yuan and will be modified to the RX01 technology bus standard. It is expected to take 9 days to launch on August 28. .

This is another project approved by the Aerospace Development Commission to recycle the Long March series of launch vehicles, starting with the Long March 6.

Originally, the space agency hoped to buy both technology and finished products, but Xinyuan did not sell it. It was the accumulation of countless launches in parallel worlds. The data in the control system sold was encrypted with a ternary algorithm, and the system was completely closed to eliminate the possibility of reverse engineering. .

After several fruitless negotiations, the space agency had no choice but to accept it. At the same time, it also issued internal instructions to "walk on two legs."

If we can succeed with Xinyuan's recycling control system, then we can accumulate some experience anyway, right? The finished product is available, but if the reverse engineering technology fails to break through, we will be held accountable.

The components of a suitcase cost 20 million yuan. For a reusable rocket, the cost is not high, and the economic benefits will definitely be earned, so the space agency paid for it.

In the following time, He Zhuang led a team of people and completed the modification project of Long March 6 with the assistance of Xinyuan engineers. It was completed two days in advance and could be launched on August 26.

At 11 a.m. that day, the Long March-6 Yaosan rocket was launched, and the third recovery attempt was made after sending the satellite into the predetermined orbit.

As the space agency waited with fear and expectation, and Xinyuan engineers waited as steadily as an old dog, Long March 6 landed safely in the center of the landing site without any surprises.

"Congratulations, congratulations to Master He, the reused version of Changliu is finally completed."

After receiving the sincere congratulations, He Zhuang suppressed the urge to run to dismantle the control system and relaxed a little in his heart.

Even if the technology is not good, can’t I copy the finished product once I get it? If you still can't figure out your own recycling control system, then you really have to resign.

And then there are two models of rockets from the First Aerospace Academy that have completely changed their configurations.

Those are the two brothers, Long March 7 and Long March 8.

The original plan of Long March 7 was to use a core stage of 3.35 meters in diameter and two YF100s, bundled with four 2.25-meter boosters, one YF100 each. The total thrust of the six YF100s was 727 tons, and the LEO capacity was 14 tons.

The first-level configuration of the Long March 8 is two less boosters than the Long March 7. The total thrust of the four YF100s is 480 tons, and the LEO transport capacity is about 8 tons.

The configuration is as follows:

The new Long March 8 uses a 3.35-meter reusable core stage, is equipped with one YF100K, and is bundled with two 3.35-meter boosters each equipped with two YF100Ks in parallel. The take-off thrust of five YF100Ks is 625 tons, and the take-off mass is 500 tons. LEO It has a transport capacity of 9 tons. The booster does not separate during recovery and is bundled on the core stage rocket for recovery as a whole. The engine of the latter is decelerated to control the landing;

The new Long March 7 is bundled with four 3.35-meter-meter boosters and two YF100K boosters. The core stage is still 3.35 meters and one YF100K. There are a total of 9 YF100K thrusters with a thrust of 1,125 tons and a take-off mass of 890 tons. It is also recovered as a whole and has a LEO capacity. 20 tons.

Although the cost has increased a lot and the dead weight recovered is also large, the technical route is conservative and easy to implement, but the carrying coefficient is a bit impressive... but it has also met the positioning requirements, right?

The only thing missing is a mature 3.35-meter core-level recycling control system.

And this recycling control system task was handed over to the Eighth Institute...

The first technical cooperation under the leadership of the Aerospace Development Commission was considered a complete success, and ISS has also begun the final selection of contractors for the manned launch mission in September.

Although it is a fair competition on the surface, with Kongcha, Xiyu and Lucia throwing away the plan parameters, in fact IISS has added an Aramco and a European astronaut, and its actions are already biased in favor of Xiyu.

In the internal survey on the intentions of subsequent astronauts, except for a few idiots who thought their own Soyuz spacecraft was the best, the rest felt that flying on the space shuttle was the most comfortable.

If the mission is carried out by Unity, its docking port will be the 1.2-meter round port on the "Harmony" node module built by Italy, and the existing 0.9-meter docking port will need to be modified.

The modification method is to remove half of the 0.9-meter round port, and then add an adapter with a height of about 50cm to connect to the 1.2-meter round port. Since the interface is on the upper part of the fuselage, it has no major impact on the structure and heat insulation. , and the design is relatively reliable.

The data of the European standard 1.2-meter round port has been sent by Alenia Aerospace Company, and the adapter is also being manufactured. It can be directly modified on the existing interface, and it only takes ten days including installation.

Although Ma Yilong's Dragon spacecraft has very good data, since it has not yet carried out a manned flight, the chance of winning is very small, and the Alliance TMA-18M is not possible for the time being.

So now the last part of the road is just for the member states within the ISS to spit on each other and strive for a little more exchange of benefits.

On the last day of August, NACA finally compromised under pressure from many parties and contracted the Space Shuttle Unity for US$145 million for the launch mission originally scheduled for September 2, which was launched by the New Yuan-2 rocket on September 17.

The reason why Xinyuan 2 is used is because there will be no astronauts on this mission, and there are four more people in the space station who will return to the ground as a rotation. Originally, three people returned on the Soyuz TMA-16M, but in the end the ISS used TMA-16M as a reserve. Stayed on the space station.

If we have to wait for Xinyuan 5, it may not be able to carry out the launch mission until November, which will greatly disrupt the deployment of the ISS.

The four people who returned to the ground agreed to return to Unity by the way. They bought three return tickets and got one free. Each person paid 1 million U.S. dollars. A total payment of 3 million U.S. dollars was enough. This directly saved an Alliance spacecraft, which can save a lot of money for subsequent missions. Woolen cloth.

It cost less than 150 million to send five astronauts up and four astronauts down. This immediately made all ISS member states feel that it was a good deal. It was much cheaper than before when it was spread to everyone.

A spokesman for the European Space Agency even said that China wants to bring cheap products from the ground to space, and believed that excluding the Chinese Space Agency from the ISS was a huge mistake.
