Yang Jie never thought of going directly to the rocket project at the beginning, but through so many years of continuous research and development in construction machinery, he has unconsciously accumulated a very deep technical strength, and when he stepped into the aerospace industry, he also suddenly found that his company's R & D team has been technically prepared in this regard. °C∮ 8°C∮8°C∮ read °C∮ book, .⌒.o≈

When Ban Zhinong led the technical team to develop rocket engines and rockets, with the help of such a huge engineering and technical team of Huaxing Group, the progress was naturally extremely fast.

At this stage, Huaxing Group has a very large number of middle and senior engineers and expert-level engineers, and there are a number of national treasure-level expert-level senior technicians, the number of which will not be less than those old international manufacturing giants.

After the technical team of Ban Zhinong designed the design drawings and design requirements of the new rocket engine, the relevant subsidiaries and R&D centers of Huaxing Group Company undertook the R&D and trial production of core components.

In particular, Yonghan Aviation Technology Co., Ltd., Machine Tool Research Institute and Electrochemistry Research Institute jointly undertake the tasks of mechanical and electronic hardware and software control of turbine pumps, high temperature and high pressure oxygen-rich gas swing hoses, high-precision and large-range digital flow control valves, rocket engine ignition devices and staged starting devices.

This time, Huaxing Group also used all the technical strength it had accumulated before to manufacture a temperature insulation material that can withstand 5,000 degrees of high temperature, and solved the most difficult components in the turbine pump, such as bearings, floating ring seals, nozzle blade grids and corrugated hoses.

The key to solving these top engineering and technical problems is that the R&D team led by Liu Fuping has developed a very special high-temperature resistant alloy material, which can withstand high temperatures of 4000 degrees, and the alloy body is very soft, but the equipment used for electron beam evaporation can withstand high temperatures and high pressures between 3000 degrees and 4000 degrees after the turbine pump turbine disk.

In order to improve the life of the rocket engine, despite the availability of such alloy materials, the technical team of Ban Zhinong made the temperature and pressure of the pre-combustion chamber and the temperature and pressure of the main combustion chamber relatively conservative when designing, mainly to extend the life of the engine as much as possible.

On the rocket assembly line, Yang Jie also saw the two Lanxing-1 first-stage rocket engines being assembled in parallel, the volume of the two engines was only a little more than two meters in diameter, only two meters in height, and the weight was controlled at three tons.

In addition to these two parallel engines, the first-stage rocket engine also leads four other transverse nozzles from the main combustion chamber to adjust the attitude of the engine when it falls back.

The first stage of the rocket is also divided into two stages, and the lowest stage will only carry a small amount of liquid oxygen and fuel to handle the last few hundred meters of landing, and most of them still rely on parachutes to reduce the speed of landing.

Like most of the rocket storage tanks loaded with liquid oxygen and hydrogen oil will still be discarded, Yang Jie wants to recycle only the two-stage rocket engine and fairing, these are the most valuable things, like the rocket storage tank is worthless.

In the afternoon, Yang Jie and others, accompanied by Ban Zhinong, rushed to the rocket engine test base dozens of kilometers away.

The site, which is located next to the coast and was originally surrounded by primeval forest, has now been equipped with several engine test benches.

At this time, the lowest rocket engine, suspended by a load-bearing belt, next to a tall tower, was testing attitude control.

In the monitoring room, Yang Jie can clearly see the attitude of the first-stage rocket at this time through many screens.

After making all kinds of preparations, the first stage of the rocket began to ignite, and the two engines below spewed out strong flames, and even through the soundproof glass, you could hear the low roar of the rocket outside!

At this time, in the screen, as the rocket sprayed a huge amount of smoke at the same time, the first stage of the rocket began to soar upward, when the rocket rose more than 20 meters into the air and then stopped in mid-air, it is still very difficult to achieve such precision in the flow of liquid oxygen and hydrogen oil.

Qiu Haiguang's eyes widened when he saw this scene: "It's really amazing that you can suspend the rocket in the air!"

Ban Zhinong also introduced to Qiu Haiguang at this time a lot of techniques that need to be used here.

After a while, the nozzle next to the first-stage rocket also spewed flames at this time, the first-stage fire shook a few times, and the whole attitude deflection occurred, and the rocket engine nozzle under the bottom also shook, and the entire first-stage rocket jumped up and down!

Ban Zhinong's face changed greatly, and he immediately shouted: "Turn off the engine immediately!"

"Yes!"

The test staff immediately pressed the emergency switch!

The first-stage rocket on the screen spewed out two flames and then stopped!

The first-stage rocket, which had lost power, fell sharply, but finally stopped under the pull of the sling, and the entire first-stage rocket swayed in the air.

"Yang Shao, this ......"

Qiu Haiguang looked at Yang Jie in surprise.

"Presumably there was a problem with the attitude control software, and this was the first time to test, and technical problems were inevitable. ”

Yang Jie opened his mouth and said.

"Yang Shao, we will solve these problems immediately......"

Ban Zhinong said to Yang Jie a little nervously.

"These rockets and engines are newly developed, new technologies account for the vast majority, problems are inevitable, you must take into account the problems in the future, do more in the test test, must ensure the stability and reliability of the rocket and engine. ”

Yang Jie said.

"Yes, Yang Shao!"

Ban Zhinong nodded hurriedly.

Yang Jie is still very confident in the reliability of the rocket, because Huaxing Group has passed a lot of rigorous tests when providing these core components of the engine, and they have been tested with high-end testing instruments.

It can be said that there will be no problems with the hardware part of the rocket now, and the problem will be in various software, if the cooperation between the software of these subsystems and the hardware is not good, there will also be big problems.

Now the company has also recruited a group of software engineers, and has written a lot of software, even if it is a software test, it will still encounter various complex problems in the actual operation process, which need to be constantly optimized and adjusted.

Seeing Yang Jie's calm appearance, Qiu Haiguang also sighed in his heart: This Yang Shao is not even thirty years old, but he is so calm and sophisticated, and he is also extremely proficient in technology, he is really born to do great things!11
