You promised to build cars, so why did you go into the military industry?

Full-flow afterburner cycle is currently an extremely advanced technology.

The rocket engine supplies most of the fuel and a small portion of the oxidizer to the fuel-rich pre-combustion chamber for initial combustion.

The generated fuel-rich gas is used to drive the fuel turbine.

The remaining small portion of fuel and the majority of the remaining oxidizer are supplied to the oxygen-enriched pre-combustion chamber for initial combustion.

The generated oxygen-rich gas is used to drive the oxidizer turbine.

Subsequently, all the generated fuel-rich gas and oxygen-rich gas are pumped into the main combustion chamber for secondary combustion.

This is to achieve full utilization of the propellant and high-efficiency energy conversion.

The fuel-rich system and the oxygen-rich system form a dual-ring system, which has stronger coupling and a more complex structure.

Unlike high-pressure staged combustion, the full-flow staged combustion cycle engine drives the turbine with full-flow gas through dual pre-combustion chambers and completely enters the main combustion chamber, which is superior to the high-pressure staged combustion cycle in terms of efficiency, thrust and life.

Logically speaking, while some companies in Europe and America are researching this technology, it should be the only one in China that is doing so, and without much success so far.

Director Qi Kaifeng was filled with regret at that moment, regretting that he had asked an extra question and made himself feel somewhat unhappy.

He waved his hand, telling Li Ran and his group to get lost.

"Wait!" Seeing Li Ran and Lin Yu just walk out of the office, and considering that the danger was different from before, Director Qi Kaifeng called them back. "After the holiday, I will send Professor Lü Chaoping from Factory 627 to your site to serve as a technical consultant for a period of time. Don't neglect him."

Technical consultant?

Li Ran's attention was drawn to this word, and he quickly realized that Director Qi Kaifeng was worried about United Industries' research and development capabilities in rockets and was afraid of any potential dangers, so he arranged for someone to act as a safety net.

After thinking it through, Li Ran readily agreed: "No problem, I guarantee you'll feel right at home."

After the National Day holiday, Professor Lü Chaoping arrived as scheduled.

Soon, Professor Lü Chaoping, relying on his professional abilities, firmly established himself on par with Wang Bing, Lin Yu, and others, and was deeply loved and respected by engineers and front-line employees.

According to Lin Yu, since Professor Lü Chaoping joined, they have benefited a lot from the production process.

"Professor Lü is indeed a veteran with more than ten years of experience. He has a wealth of experience and helped us avoid many pitfalls."

Unexpectedly, Professor Lü has extremely unique insights into full-flow staged combustion cycle rocket engines.

With his help, I am confident that I can carry out a major upgrade to the existing rocket engines before the end of the year.

I estimate I can lose more than half my weight.

Lin Yu said this at the internal progress report meeting.

In order to fully learn from Professor Lü Chaoping's experience, Wang Bing decided to hold intensive learning classes every Wednesday and Friday after get off work, as well as on Saturdays and Sundays, with Professor Lü Chaoping in charge of teaching. Participating employees can receive a salary subsidy.

At the end of October, under Shen Zijie's arrangement, the first batch of 3000 self-produced tablets began to be distributed within the company.

In conjunction with the internally developed ERP and WMS systems, the company has achieved complete autonomy in internal operations and material warehousing and allocation data, initially eliminating its dependence on external systems.

Looking at Wang Bing and Shen Zijie who had come to deliver the goods, and stroking the newly acquired tablet, Li Ran finally voiced the question that had been on his mind:

"I understand the necessity of chip self-sufficiency, and I also understand that the sooner we catch up, the easier it will be."

But why do you all seem to be in such a hurry?

"Mr. Li, the 45nm process chip we manufactured ourselves contains nearly 8 million transistors."

You're saying it's difficult for us to install a back door inside without anyone noticing...?

Wang Bing pointed at the tablet in Li Ran's hand, expressionless.

"Previously, from the perspective of external capital, we were just a car manufacturer."

Although the engine is very energy-efficient, it is still just a sophisticated toy with some technology, built in conjunction with an energy storage battery.

A mass-produced internal combustion engine with a thermal efficiency of 43% is impressive, but countless laboratories around the world have successfully built internal combustion engines with thermal efficiencies of over 48%. Our 1.5L internal combustion engine is simply not worth paying attention to.

As for the so-called intelligent automatic parking function, which is riddled with limitations, looks good but is not practical, and has more emotional value than practical value, industry insiders believe it is nothing more than a marketing gimmick.

Therefore, in the past, we were regarded by the industry as nothing more than a marketing opportunist.

But with the Rockets, it's hard to say.

Noticing Li Ran's serious expression, Wang Bing smiled:

"However, since Professor Lü Chaoping arrived, the problem has been solved."

"If we can apply our photovoltaic technology to CNSA and call ourselves a contract manufacturer, why can't we do the same for this rocket?"

Li Ran's eyes widened, her expression saying, "Is this even possible?"

"Professor Lü Chaoping is remarkable. He has extremely profound and unique insights into the technology of full-flow staged combustion cycle rocket engines."

Under his guidance, we are about to achieve a second upgrade of our existing rocket engines.

However, there is currently only one rocket engine in China that uses the same technical approach: the YF-100. There are probably not many people with expertise in this area.

"Considering that Director Qi said the YF-100 only recently passed acceptance..." Wang Bing took a deep breath, "I strongly suspect that Professor Lü Chaoping is one of the key technical personnel in the YF-100 team."

On November 1, Shenzhou-11 was successfully launched into space.

The 'Chang Er F-Gai' that had gained weight on TV was still as eye-catching as ever.

"It's a pity I didn't have time to go see it in person. I wonder what changes and enhancements Shenzhou-8 has undergone." Lin Yu looked at the spaceship animation on the TV screen, feeling a sense of longing.

But right now, he has more important things to do.

To facilitate a smoother second upgrade of his rocket engine, Lin Yu, with the assistance of Professor Lü Chaoping, produced a small engine at a 3:1 scale for testing.

Now, this rocket engine, produced at a 3:1 scale, is set up on a self-built test stand in a remote valley, ready for testing.

Clear the site and evacuate the personnel.

The rocket engine in the distance, with its numerous connecting flanges and large welding marks resembling scars, is particularly eye-catching.

With the "ignition" command issued, liquid oxygen and liquid methane, aided by their respective pumps, flowed into different pre-combustion chambers through external pipelines, forming fuel-rich gas and oxygen-rich gas.

After ignition in the pre-combustion chamber, the pressure in both pre-combustion chambers rises rapidly...

Soon, blue-white flames shot out from the main combustion chamber.

The flames struck the spray cooling device, producing a large amount of water mist that obstructed the view.

Lin Yu stared intently at the real-time data transmitted back from the engine sensors displayed on the screen, listening attentively while taking notes.

The seemingly rhythmic rumbling sound, enhanced by Lin Yu's [Mechanical Resonance] property, resembled a patient rambling on about their condition to their attending physician.

Soon, the test ended, and Lin Yu looked at the rocket engine that was faintly visible in the mist, as if he had an epiphany.

On December 26, Li Ran learned from the news that the first aircraft carrier had been officially delivered.

The aircraft carrier in the footage looked almost identical to what he remembered. However, in a scene of a turning test, Li Ran deduced from the reference points that at a speed of 25 knots, a 180° turn would create a wave circle with a diameter of about 1000 meters, corresponding to a turning radius of about 500 meters.

"Hiss... its mobility is comparable to that of the Nimitz-class." Li Ran clicked his tongue in amazement.

At the end of January 2013, a rocket engine with virtually no visible connecting flanges between traditional components and an integrated pump and valve housing officially rolled off the production line.

This generation of rocket engines adopts an internal flow channel and internal sensor design, which improves the system's compactness and overall performance.

The engine's reliability was improved during launch and reentry into the atmosphere, reducing the risk of damage during operation and making engine reuse a possibility.
