Chapter 398 F Series Rocket Engine

"What Mr. Liu said is what I thought. Mr. Xun, how is your production capacity?" Wang Hui turned around and asked.

"Now that the work on "Genesis" has been completed, it is not impossible to get the project started, but it will probably take two or three years for this game to be released." Xun Haoran replied.

"It doesn't matter, "Genesis" is not a short-term game."

"Then it's fine."

"Well, then Mr. Xun, you should start the project first! By the end of this year, we can use this to speculate on the stock price of the future era." Zhuge Chuang said.

Xun Haoran nodded.

"How many gaming helmets can be produced in the short term?" Guo Yuan asked.

“The main structure of our helmet is something similar to a solid-state memory, plus a head-mounted brain-computer interface chip, as well as a signal receiving and sending device, and finally a chip similar to a mobile phone processor.

If these things are in place, assembly will be quick.

The chip for the head-mounted brain-computer interface is our own technology patent and is entirely produced by Longcheng Biology, and the rest can be purchased directly. "

"The cost of so many things only costs over 400 yuan? Mr. Xun, are you right?" Liu Xiaoyin asked in surprise.

"Don't worry, I'm not mistaken!"

"Are all the things used of inferior quality?"

"No, the chip we use is about the same as Snapdragon's 8gen1. The chips used in today's mobile phones costing more than 1000 yuan are not as good as this!
The main purpose of our use of this chip is to connect the core chips and memories of the head-mounted brain-computer interface in series, and then through the signal sending and receiving devices, enter the game backend built by our supercomputing cluster group.

Therefore, there is no need to use the most advanced chips on the market. The chips in flagship phones from about 5 or 6 years ago are enough. "

"What is the purchase price of such a chip?"

“伱要放到5，6年前，2020年那会儿，骁龙8gen1一块在900元左右。

Now you can get it for almost 200 yuan, and the chip we are using is not 8gen1 but a domestically developed chip. Calculating the cost is lower, the price of each piece is about 130 yuan.

As for memory, memory chips are now cheap. The memory module built into our helmet is 1TB, and the cost is only a little over 100.

Calculated, our own head-mounted brain-computer interface chip is the most expensive, costing more than 150 yuan, and then there is the main body of the helmet. The boss of the helmet requires that it must have 3C certification. This cost is more than 40 yuan, and the total is 450 yuan. the cost of. "

"How much can we earn by selling for 450 at a cost of 998?" Liu Xiaoyin asked.

"About 300!"

"Only 300? What about the remaining 248 yuan?" Wang Hui asked.

"Major dealers! Like e-commerce platforms, they can't sell it to you for free!" Zhuge Chuang said angrily.

“Is the e-commerce platform so profitable?”

"Nonsense, why do you think these companies spend so much money to establish a monopoly? Only when they have a monopoly can they make money."

"We have worked so hard to develop new games and master new technologies, and they can earn almost [-]% just by sitting there? This money comes so easily!" Liu Xiaoyin sighed.

"What 548%! It's obviously half. Our net profit is only 248. They earn 300, and we earn [-]. Isn't this half?"

"Then can we leave these people behind and do it ourselves?"

"What are you thinking! It's impossible. Not to mention whether the logistics can be solved, the cake has to be divided by everyone. If you eat all the cake by yourself, you will only become the public enemy of all companies and enterprises!" Zhuge Chuang said in a serious tone. said.

"That's right, cutting off someone's financial resources is like killing one's parents. This kind of thing should never be done."

After some discussions, Future Technology executives determined the next development direction for the future era.

After they left, Guo Yuan called up the surveillance footage of Future Heavy Industries.

At this time, according to Guo Yuan's design drawings, all engine parts have been 3D printed at Future Heavy Industries.

The nozzle previously used for testing has also been sent.

Now Shan Tianning and the others have begun assembling the first rocket engine.

Guo Yuan unified the rocket engines of future technologies starting with F.

Because the English word for future is Future.

The first rocket engine was called F-001.

With the support of Future Heavy Industries' advanced intelligent production line technology, Shan Tianning and the others have already begun assembly.

In the picture, the previous nozzle is hoisted under a frame, and other parts of the engine are placed on shelves nearby.

Shan Tianning took the lead and stood next to the nozzle to direct the employees in the team to assist him.

Starting from the upper part of the combustion chamber, assembly started bit by bit. Valves, hoses, and parts were installed on the main combustion chamber through Dan Tianning's hands.

Most parts of the F-001 engine are manufactured by mechanical automation. With the support of high-precision technology, the probability of parts requiring repair during engine assembly is extremely low, which ensures the assembly efficiency of the engine.

Seeing the work being carried out in an orderly manner on the screen, Guo Yuan turned off the monitoring screen.

According to the current progress, the first test of the F-001 engine can already be arranged.

There is a rather embarrassing thing now. The headquarters of Future Aerospace is still under construction.

China Construction won the tender before, but now it has just finished laying the foundation, so it is impossible to use it directly.

This resulted in the fact that F-001 could only choose an external test bench for its first test run.

So Guo Yuan asked Cao Huaimao for help and borrowed the testing ground in Cao Huaimao's laboratory.

Cao Huaimao and others who want to develop drones must have a testing ground. Guo Yuan had previously thought that their testing ground was quite large, and borrowing it for use should not be a problem.

So Guo Yuan submitted the application for engine testing.

Cao Huaimao was also very interested in Guo Yuan's rocket launcher.

He also wanted to see what kind of engine Guo Yuan had built, so he decisively agreed.

Cao Huaimao knows a lot about engines, because his main job is actually not drones, but the research and development of various missiles.

Missiles inevitably use engines. Missile engines and rocket engines are actually similar.

Because both usually include the following main parts:

1. Combustion chamber: This is the central part of the engine. Fuel and oxidant are burned in the combustion chamber to produce high-temperature and high-pressure gas.

2. Nozzle: The nozzle is the part used to inject high-speed gas.It usually has a nozzle throat, where the gas is accelerated, and a nozzle mouth, which is used to diffuse the gas to reach higher velocities.

The difference is that rocket engines can be divided into many types based on their working principles and the fuel they use, the most common of which include:
1. Chemical rocket engine: This engine uses chemical reactions to generate high-temperature and high-pressure gas to propel the rocket.Common fuels include liquid fuels (such as liquid hydrogen and liquid oxygen) and solid fuels (such as solid rocket motors). 2. Nuclear rocket engine: Nuclear rockets use nuclear fission or nuclear fusion reactions to generate energy. These reactions are usually more powerful than chemical reactions.However, nuclear rocket technology is more complex and carries higher safety risks.

3. Ionization propulsion engine: Ionization propulsion engine uses an electric field or magnetic field to accelerate ions, and then discharges the ions to generate thrust.This type of engine is commonly used on space probes and satellites because of their ability to provide low thrust for long periods of time.

Different rocket engines are suitable for different missions and environments, and selecting the appropriate engine type depends on mission requirements such as thrust, fuel efficiency, payload capacity and required speed changes.

A breakthrough in rocket engines may actually directly lead to missile engine upgrades.

Two days later, Shan Tianning and the others transported the assembled engine to Cao Huaimao's testing site.

Cao Huaimao only left the person responsible for data recording, and the others asked them to retreat first.

This is also for future technology product privacy considerations.

If the equipment here wasn't so important, Cao Huaimao would have wanted someone from Future Technology to record the data.

On a wooden base, Guo Yuan saw the F-001 engine covered with moisture-proof cloth.

Shan Tianning directed the team members to remove the mask, and Guo Yuan saw the engine he designed for the first time.

Guo Yuan took two steps forward and walked to the engine. He reached out and grabbed the pipe on the outside of the engine and tried to shake it.

Of course, with the little strength in Guo Yuan's hand, it was impossible to shake the engine pipe.

Cao Huaimao couldn't help but step forward and walk around the engine to observe.

"Is this your engine?" Cao Huaimao asked after turning twice.

"Yes, Team Leader Cao." Shan Tianning nodded and said.

"Can such a small engine send a rocket into space? It looks about the same size as an engine used in ordinary missiles!"

“This engine is a sea-level version and can only be used at altitudes below 70km.

After the altitude exceeds 70km, the sea level version of the engine nozzle design will no longer be able to provide the thrust it deserves.

The reason is related to the atmospheric pressure in working environments at different altitudes. In order to ensure the thrust performance of the engine in high suborbital and outer space, it is necessary to design a new vacuum version of the F-series engine. "

"So that's it, so this engine can be adapted to various missiles, right?" Cao Huaimao then asked.

Dan Tianning and the others scratched their heads, not knowing how to answer for a moment.

Why does Team Leader Cao never leave the island?

"Ahem, Director Shan, compared with the sea-level version of F-001, what areas need to be modified in the vacuum version?" Guo Yuan cleared his throat and changed the topic.

“First of all, because the air pressure in vacuum is extremely low, the nozzle needs to be optimized to better adapt to the vacuum environment.

Specifically, the vacuum version of the rocket engine nozzle generally uses a longer cone-shaped nozzle to accelerate the discharged high-temperature and high-pressure gas to a higher speed, thereby improving thrust efficiency.

In addition, the vacuum version also needs to add some special equipment, such as vacuum igniter and vacuum propellant supply system. "

Guo Yuan nodded when he heard this, but Guo Yuan did not plan to participate in these tasks anymore.

Real rocket engines are the main power devices used to propel rockets or spacecrafts. They generate reaction force by injecting high-speed exhaust gases to propel the rocket or spacecraft forward.

Rocket engines work based on Newton's third law, which states that every action has an equal and opposite reaction.

Shan Tianning has been immersed in this industry for many years, and Guo Yuan believes in Shan Tianning's ability.

They will definitely be able to complete the corresponding modification design based on the existing F-001 design.

"Are you all ready?" Cao Huaimao asked.

"Ready!" Future Technology employees and test base staff shouted in unison.

"Then let's get started!"

Rocket engine testing is a complex and expensive process, but it is a critical step in ensuring the success of the launch mission and the safety of the flight.

Through thorough testing and validation, engineers and scientists can ensure rocket engines operate reliably in extreme environments, enabling successful missions ranging from space exploration to communications to scientific research.

Before a rocket engine can be tested, it goes through multiple stages, including design, manufacturing, assembly and preparation.

This time it was ready, but it took a lot of people and a long time of hard work.

Dan Tianning injects fuel into the engine. There are actually many fuels for rocket engines. The major categories include liquid fuel, solid fuel, and mixed fuel.

This test mainly used liquid fuel.

Moreover, the goal of future aerospace is liquid rockets, and the engine is also designed with this idea in mind. The combination of liquid fuel and oxidizer will be used in the future.

It is also appropriate to use liquid fuel for this test.

Common liquid fuels include liquid hydrogen, liquid oxygen, methane, methanol, ammonia, and various combinations of liquid fuels and oxidizers.

Dantinine is added with methanol-based fuel.

After the fuel injection was completed, Dan Tianning started the engine.

The roar of the engine filled the sky, and Guo Yuan could even feel the ground beneath his feet shaking.

"First item, static testing begins!"

The so-called static test is a test conducted on the ground, which is used to evaluate the performance and reliability of the rocket engine.

In this kind of test, the engine is usually mounted on a support structure and ignited to burn, but the rocket itself does not take off.

This allows engineers and scientists to collect data on thrust, combustion stability, combustion efficiency and material properties.

Half an hour later, when the data collection was completed, Shan Tianning shouted stop.

After Cao Huaimao took a look at the recorded data, his eyes lit up. There was something special about this engine!
"The second continuity test!" After the engine cooled down, Dan Tianning started the second experiment.

Rocket engines need to undergo long-term continuous testing to verify their performance and reliability in long-term operation.

This type of testing can simulate the sustained thrust demands of a space mission, ensuring the engine remains stable for multiple hours, days or longer.

The test results this time were also very good.

Cao Huaimao's eyes are obviously brighter, and the sustainability of this engine is also very good!

The stronger the sustainability, the longer it can hit when placed on a missile. This test engine is estimated to be used by some medium-range missiles based on its performance.

If it is the full version, can it be used by some special missiles?
