This liquid oxygen methane engine system adopts gas generator circulation, coaxial turbine pump, one turbine pump supplies two thrust chambers, and the engine adopts pump post-swing technology, with a swing angle of ±25° to realize the pitch, yaw and roll control of the rocket.

In addition, it also adopts self-generated pressurization technology, which uses methane high-pressure steam to directly provide pressurized medium for the fuel tank.

At the same time, it also uses the hydrodynamic pressure sealing technology independently developed by Huaxing Rocket Launch Company in recent years, and applies it to the engineering development of liquid oxygen methane rocket engine.

One of the keys to the reuse of this technology engine is that it has the advantages of low leakage, zero wear, and adaptation to multiple starts and stops, and has been used on previous liquid oxygen and kerosene rocket engines, and is very reliable.

In addition, Huaxing Technology Group Co., Ltd. independently developed high-precision high-pressure low-temperature mixing ratio regulator technology is also used, the regulator is driven by the motor, the controller to achieve low-temperature engine mixing ratio stepless adjustment, can greatly reduce the residual fuel of the rocket, improve the carrying capacity of the rocket.

Huaxing Technology Group Co., Ltd. technology patents in many technical fields can be quickly used by Huaxing Rocket Launch Company, so the speed of development is very fast.

The technical patents accumulated by Huaxing Technology Group Company and domestic research institutions over the years have also enabled the liquid oxygen methane engine developed by Huaxing Rocket Launch Company to achieve very good results in many test runs.

The engine starts and shuts down smoothly and quickly, the measured results are in good agreement with the calculated values, the working height of the thrust chamber is consistent, the dynamic amplitude of the vibration arteries of each component is low, and the product is in good condition after testing.

This liquid oxygen methane engine has been tested for reliability for a long time under various working conditions, and has achieved the previous design goals, and has also accumulated a large amount of experimental data.

The successful development of this set of liquid oxygen methane engine system has also greatly increased the confidence of the technical team led by Ban Zhinong, and is steadily developing a ten-ton three-stage rocket on the basis of this technology, and then slowly transferring the technology to the two-stage engine and a larger one-stage rocket, and finally forming the design and development of the liquid oxygen methane overall rocket.

Huaxing Rocket Launch Company's development of the upper stage using liquid oxygen methane engine is smaller than that of the Da Mao warship bird upper stage, although the density of liquid methane is smaller than that of metadimethylhydrazine, but it is much higher than the specific impulse.

In addition, Huaxing Rocket Launch Company also uses the mature 20 kilowatt power level arc engine as an indispensable attitude control for the upper stage, and the power supply comes from a high-temperature solid fuel cell system.

The high-temperature solid-state fuel cell system is jointly developed by the Electrochemistry Research Institute of Huaxing Technology Group and the Uillich Research Center in Germany, and the battery has a continuous service life of more than 70,000 hours.

Such a set of high-temperature solid-state fuel cells is extremely reliable, using methane and oxygen to generate electricity, which can meet the needs of magnetic accumulation arc engines.

"Honey, isn't the liquid oxygen methane engine you developed very powerful?"

Natasha looked at the upper-level system in front of her and asked Yang Jie curiously.

"Well, we are indeed at the forefront of the world in this regard at this stage. ”

Yang Jie said with a smile.

"Dad, did you invent this?"

Amanda tilted her head and asked Yang Jie at this time.

"No," Angelo on the side said at this time, "This is designed by Uncle Ban Zhinong." ”

Ban Zhinong on the side also asked Angelo with a smile: "Angelo, how do you know?"

Angelo said proudly, "Because my father told me." ”

Yang Jie smiled and rubbed Angelo's little head, Angelo seemed to be very interested in rockets, he had also inadvertently mentioned it to Angelo before, but he didn't expect the little guy to still remember it.

In the evening, Yang Jie also held a meeting with the management and technical team of Huaxing Rocket Launch Company.

"The headquarters is about to start the plan to launch a spacecraft this year, and I hope that the spacecraft will be able to be matched with our own heavy rockets after it is developed. ”

Yang Jie's gaze swept over the faces of Ban Zhinong and the others: "Do you have confidence in this?"

Ban Zhinong said: "Yang Shao, the 300-ton liquid oxygen kerosene rocket engine jointly developed by us and Da Mao has completed various technical tests and verifications, and the new heavy-duty rocket is now in trial production, and it can be tested and launched at the beginning of next year." ”

Yang Jie nodded: "Since the 300-ton liquid oxygen kerosene rocket engine has matured, then transfer all your energy to the liquid oxygen methane engine, and strive to launch the 500-ton liquid oxygen methane engine within a few years. ”

Ban Zhinong and others are still very confident in this, although the two-ton liquid oxygen methane engine developed before has been unable to break through the 76% mark in the test process, and then Ban Zhinong led the technical team to redesign the gas generation and turbine pump system, which is equivalent to redesigning the core components, which is also very difficult.

As a result, it only took three months for Huaxing Rocket Launch Company to complete all the updates, and after a series of tests, the engine system was finally matured.

Of course, all these changes are also related to the huge capital and technical talent reserves of Huaxing Rocket Launch Company, Yang Jie has injected more than 10 billion funds into the company every year every year, and it has also enabled Huaxing Rocket Launch Company to realize the steady transition and growth of this series of engines from dimethylhydrazine fuel to liquid oxygen kerosene rocket and to liquid oxygen methane, and the technical foundation is very solid.

The fact that this liquid oxygen methane rocket engine solved the problem in a few months and achieved such a large iteration is a complete testament to the technical strength of the technical team.

With this small liquid oxygen methane rocket engine technology as the foundation, the technical team led by Ban Zhinong is naturally more confident in developing a 500-tonnage liquid oxygen methane rocket engine.

If the 500-tonnage class engine is connected in parallel, it is enough to meet a lot of needs, and it is completely sufficient.

The big boss in front of him is more concerned about the commercial development of space, and has no interest in competing with other countries in rocket engine technology.

Over the years, Huaxing Rocket Launch Company has paid more attention to rocket reliability, reusability technology and reducing launch costs in rocket technology research and development, and has a very clear goal in reducing costs every year.

Over the years, the technical team led by Ban Zhinong has continuously used new technologies to ensure the safety and reliability of rocket launches from all aspects, and at the same time has continuously carried out the research and development of cutting-edge rocket technology.

Ban Zhinong sometimes has to be glad that he made a very correct choice in his life, that is, to follow the boss Yang Jie.

This boss has a very keen business sense, and very cleverly chose the technical route of liquid oxygen methane engine, and from the current technological progress, their choice is very correct.
