Movie black technology

Director Zhu took out the experimental report of the past few days, "Compared with the fuel you used to mix, this pure monster blood is too dangerous."

"Especially when it encounters lanthanum, a little more will explode, but if we add less pure lanthanum, its combustion will not be sufficient, and the amount of it is difficult for us to control..."

"The most terrible thing is that once the supply of pure lanthanum is stopped, the reaction of the blue blood will be stopped quickly, and it will not be able to sustain combustion in the combustion chamber..."

After listening to Director Zhu's more detailed description, Chen Shen understood the problems they encountered now...

The burning of blue blood cannot be achieved by throwing a match into the blood.

The principle of the liquid hydrogen and liquid oxygen engine is to ignite a fire when hydrogen and oxygen are mixed, so that the two can deflagrate, and generate thrust through the burning exhaust gas.

If this process is applied to the blue blood rocket, it can be said that blue blood is the mixed state of hydrogen and oxygen, and pure lanthanum is the igniter for ignition.

As long as the two come into contact, the combustion will start, and then the combustion products will be projected outward, and then the thrust will be generated, and the engine will be started.

But there's a little difference here.

The ignition of the liquid rocket engine only needs to be ignited once, and the combustion chamber can maintain its own combustion. Then just continue to send hydrogen and oxygen into the combustion chamber, and there is no need to ignite again.

But Blue Blood Fuel is different.

Blue blood will only react violently when it encounters lanthanum. Once the supply of lanthanum is stopped, the reaction of blue blood will also stop quickly.

That is to say, pure lanthanum is not like an igniter, which only needs to work once. It must continue to mix and react with blue blood, so that the burning of blue blood can continue.

To put it more vividly, the two fuel delivery pipes of the engine must be like a liquid engine, one supplying blue blood and the other supplying pure lanthanum, and then let the two meet and react in the combustion chamber to release energy.

If pure lanthanum is like an igniter, if it only ignites a part of the blue blood at the beginning and then stops working, after this part of the blue blood is burned, the blue blood that continues to be sent in later will not burn.

If no chemical reaction occurs, the engine will naturally stop.

As a result, the delivery control of the amount of pure lanthanum is very critical.

Once there is a little more or less, the result is either that the combustion is out of control and explodes, or the combustion is not sufficient, and the thrust generated is not enough, and the engine can't fly after a lot of humming...

In this case--

The Blue Blood rocket may become the first rocket in the world to lie on a launch tower.

But it is not difficult to solve this problem, and the answer is very simple in summary.

That is to control the amount of pure lanthanum delivered, more when it should be more, and less when it should be less, so that it can maintain the balance between combustion and explosion when it reacts with blue blood.

Unfortunately, the properties of blue blood are extremely unstable, especially after contact with pure lanthanum.

Once these two substances come into contact, a violent reaction occurs every moment. The speed of flow, the angle of collision and even the temperature change between the two will seriously affect the reaction process.

Finding the balance line is not something that can be done in a week or two of experimentation.

Just like the previous liquid engine, it gradually became mature and reliable after a lot of calculations and experiments.

Now the blue blood engine is just in the stage of discovery, everyone's control and understanding of blue blood is not perfect, so the results of Director Zhu's experiments are either out of control or insufficient combustion...

No matter how you calculate, no matter how you experiment, you can't touch the balance line.

In the semi-sheltered test field outside the laboratory, there are also several simulated engine systems, which are specially used for fuel tests between blue blood and pure lanthanum.

Chen Shen took a look at their structure.

Obviously, they are all modified according to the structure of the hydrogen-oxygen engine.

It's just that the original hydrogen-oxygen fuel delivery pipeline has been changed to deliver pure lanthanum and blue blood.

At the same time, the igniter, turbo pump and other parts that do not completely match the blue blood engine have been deleted or adapted.

The previous experiment was done here.

"Now we have two directions."

Chen Shen put down the experimental report in his hand and faced all the researchers and experts in the project.

"The first one is to solve the self-sustaining combustion problem of blue blood in the combustion chamber, and let pure lanthanum return to the function of the igniter. After the blue blood is ignited, it can maintain combustion in the combustion chamber, instead of putting the Pure lanthanum is used as an integral part of the fuel."

"The second direction," Chen Shen held up two fingers: "That is to continue the current thinking and conduct a continuous reaction experiment between pure lanthanum and blue blood, so that pure lanthanum can fully participate in the reaction of blue blood."

"Of the two roads, the first one may be more difficult, but the prospect is better. Once successful, the reliability of the engine should be much better than the second method."

"The second way can be realized by stacking a large number of experiments and calculations, but the stability of an engine that is undergoing explosive and violent reactions all the time is definitely not much better."

After igniting the engine in the first direction, you don’t need to worry about it, but in the second way, you need to ignite it from time to time, and you must prevent it from exploding or the output is too low. There must be a problem with the stability of the body.

Director Zhu next to him thought while listening, "I think we should choose the first path. Although it is more difficult, as long as we have enough time, we are confident to overcome this difficulty."

Hearing Director Zhu's words, the other experts and researchers behind him nodded.

They really have this confidence.

The entire Rockets system has been ups and downs this year, and now they have finally seized an opportunity to bring the Rockets system back to its peak. They are holding back their energy and have nowhere to use it.

Chen Shen smiled, very pleased with their thoughts, and then said: "You guys are wrong, I mean there are two paths, we have to go."

"Whichever way works, we will use whichever one."

Anyway, there is no shortage of money or resources.

If the blue blood rocket is successful, the construction of the space factory and other space projects will be much easier.

Everyone present was taken aback for a moment, and then they all laughed tacitly.

"Director Zhu first divide the project into teams according to the two directions I mentioned earlier. Divide them into two groups, each responsible for one direction."

Chen Shen left temporarily, looking at the simulation system of the engine and thinking about the two directions he just proposed.

Among these two directions, his favorite is actually the first direction.

Because this plan is the best plan.

But the biggest problem in this direction is to find the right way of thinking.

That's what he's thinking now.

When Director Zhu initially divided the people into groups and came back, Chen Shen already had some ideas.

He pulled Director Zhu to the front of the simulated engine:

"Since the reaction between pure lanthanum and blue blood is difficult to grasp, is it possible for us to use another method to bypass this procedure?"

Director Zhu got excited when he heard it, pricked up his ears, took out a pen and paper from his quilt pocket, "How do you want to get around?"

Chen Shendao: "It's very simple."

"The previous engine used the method of catalyzing lanthanum and blue blood to directly contact in the combustion chamber, and then react."

"Then is it possible for us to change the method and set up double or even more combustion chambers in the engine?"

"First let a very small amount of catalytic lanthanum and the same small amount of blue blood burn in the primary combustion chamber, and then send the starting blue blood to the secondary combustion chamber, and at the same time input an appropriate amount of blue blood from another pipeline, let them put together."

"In this way, the ignited blue blood will become the primer, igniting the newly fused blood."

Director Zhu's eyes lit up, and he continued following Chen Shen's train of thought: "Use the blue blood to ignite the blue blood, so that there is no need to control the amount of pure lanthanum!"

"Moreover, pure lanthanum is used as an igniter, which only ignites a very small amount of blue blood. If you don't pursue directly reaching the energy release standard, the controllability will suddenly increase!"

When pure lanthanum meets blue blood, it will cause a violent reaction from blue blood, but when ignited blue blood meets unignited blue blood, a violent reaction cannot occur between the two.

This method is like putting a little dynamite on the paper, setting it on fire, and then using this piece of paper to set a lot of paper on fire.

The previous method was to put a lot of explosives on a lot of papers, so as to ignite the papers, but not let them scatter due to the explosion, and let them stay where they are and be burned obediently...

Which of these two approaches is more difficult is visible to the naked eye.

This idea might actually work!

Based on experience, Director Zhu already had a vague premonition in his heart.
