"Bang!"

As soon as Lu Yi and the others returned to the laboratory, a loud noise came from a wasteland behind the space project area, and the sound was very dull, like a torpedo exploding underwater.

"This madman!"

Feeling the smoke and heat diffused in the air, the corners of Lu Yi's mouth twitched a little, and he really guessed that Wei Hong was testing with a bomb.

If he guessed correctly, it was a thermite-modified bomb used.

The thermite reaction can produce a high temperature of more than 2500 degrees Celsius, which can turn the gas into a plasma state, as long as the bomb dose is calculated and controlled, some actual data can still be collected by borrowing the blast impact.

As for the bomb experts and bombs, next to them is the Yangcheng Military Region, which is not difficult according to the relationship of the laboratory.

Coming to the wasteland behind the space project, in addition to Wei Hong and several of his researchers, Commander Huang and a few bomb experts, even Hu Feng and other researchers in the laboratory who were a little curious about the experiment were gathered in a heap.

Seeing Lu Yi and a few people coming, everyone moved out of the way, but when Lu Yi saw the test bench seventy or eighty meters away, his face suddenly darkened.

What is placed on the test bench is not a space engine in the conventional sense, but a standard space engine bell-shaped nozzle, and the dense superconducting coils are messily fixed and wound around the nozzle again and again.

Obviously, these superconducting coils imitate the action of the magnetic field coil outside the stellarator, forming a restraining magnetic field blocking plasma on the inner wall of the nozzle.

These design structures are fine, and they still match the design scheme, but they are a little messy because this is an experiment, which can be understood and accepted.

But what do you mean by almost soldering the nozzle opening?

The thrust principle of a space engine is analogous to a firecracker covered with a cup and then the cup is blown up.

The propulsion fluid expands at high speed in the nozzle, and the pressure acts on the inner wall, but because the nozzle is bell-shaped or cone-shaped, there will be an opening, and the pressure will vent at the opening, but other directions will touch the inner wall and cause obstacles.

This uneven expansion pressure, combined with the high-velocity recoil of the propelled working fluid, eventually results in a thrust force that is opposite to the direction of the nozzle opening.

You've welded the nozzle openings to death, what else are you trying to do?

Seeing that the nozzle was almost completely welded, leaving only a hole in the middle to vent the internal explosion pressure test engine, Lu Yi asked Wei Hong next to him with a dark face: "Are you in the fryer, is this the engine?" ”

"Boss, I can't help it, we don't have a backup fusion reactor.

I said that the current reactor reserve gap should be opened, and a new deflector should be replaced to connect the ultra-high temperature exhaust gas, but it was rejected on the grounds that the construction of the ferrofluid power generation module had not yet been completed, and we did not have a small nuclear bomb, so I had to ask Commander Huang to borrow some thermite modified bombs for testing. ”

Wei Hong said helplessly: "Who would have thought that the energy of the thermite, which usually sounds very powerful, is so small, and if the nozzle opening is sealed to block the leakage of energy, the plasma state of the gas will not last long at all." ”

"In this way, after the weld is dead, the expansion pressure and even the recoil force will cancel each other out, how do you get the test data."

Lu Yi looked at the welded space engine nozzle on the test bench and asked, "Pressure sensing?" ”

"Yes, pressure sensing, we don't have a fusion reactor, we don't have a small nuclear bomb, and we can't test the real data of this space engine in its entirety."

Wei Hong looked at the test engine that had just eaten a thermite bomb and was still dissipating heat, and said: "I am just testing the data of the confined magnetic field, further optimizing the confined magnetic field, and at the same time collecting the expansion pressure data and recoil data, and simulating and analyzing the optimal shape of the nozzle."

These two tests can be done with a high-sensitivity pressure sensor and a temperature sensor mounted on the inner wall sandwich, but the test is limited to this, and further tests are carried out to improve the ultra-high temperature exhaust gas or small nuclear bomb that I need for a fusion reactor. ”

It's a fusion reactor again, and it's a small nuclear bomb......

Lu Yi rubbed his forehead with a little headache, and said to Wei Hong: "I will give you the second nuclear fusion reactor you want in two months." ”

A few days ago, it was determined that the controllable nuclear fusion was successful, and the Tomorrow Group, which had obtained the construction qualification, immediately placed orders for nuclear fusion reactor-related components to major domestic industrial groups at a higher price, and several high-precision components involved also placed orders on the eastern island countries.

According to the schedule, it will take about 26 days to complete the production of the relevant components of the fusion reactor, and even if the first one is built and the second one is experienced, it will take a month and a half to build the world's second nuclear fusion reactor.

In addition to Wei Hong, a madman, who is urging the ultra-high temperature exhaust gas of the nuclear fusion reactor every day to improve the design of the space engine, the main reason is that the experiments and supercomputing in the laboratory are using more and more electricity.

Yangcheng's power supply was already tight, and now the power supply bureau hid when it saw the person in charge of daily affairs management in the laboratory, for fear of saying that it would expand the power capacity.

"Two months, okay then."

Wei Hong was a little disappointed, he had been thinking about opening the gap in the current reactor so that it would not take a month.

"You test it first, be careful not to cause a fire, and pay attention to the occasion when there is a small nuclear bomb, and don't always talk about it!"

The small hydrogen bomb is too sensitive, and he also said it when he submitted the report that day, and he did not ask about the subsequent time in Beijing.

After explaining Wei Hong's attention, Lu Yi didn't care about this madman, turned around and walked towards the controllable nuclear fusion laboratory.

I didn't see Rupert's old guy here just now, and after a few months of research on the miniaturization of controlled nuclear fusion reactors, Lu Yi felt that it was necessary to determine whether this old guy had encountered any difficulties and obstacles, which was also a master who didn't like to post experimental progress reports.

"Lu Lu, the reactor has reached the design power after adjustment in the past two days, Dean Wang said that the preparation for the briefing conference has been completed, and asked us when we are sure when it will start."

At this time, Zhang Qing came up to remind Lu Yi of something that he was almost busy forgetting.

The breakthrough in controlled nuclear fusion was supposed to have a formal press conference, after all, it was a "multinational" joint project.

When Lu Yi proposed to put this briefing at CUHK, although it was a little inappropriate, it also gave Chief Engineer Lu face and agreed, but Lu Yi almost finished this matter in the past few days because of the heat crisis.

"If you don't say it, I really forgot to say yes."

Lu Yi smiled bitterly, thought for a while and said, "Tell the dean, the time is set for ten o'clock in the morning the day after tomorrow, and I will let Senior Sister Xu Ying follow up on this matter."

Today I'm going to deal with the miniaturization of nuclear fusion and see what the hell Rupert is up to.

Tomorrow we will have a video conference with the ligo project team, and with the help of the above relationship, the United States NSF has promised to give us the parameter data of the ligo observatory. ”

"Parametric data from the Ligo laser interferometer gravitational-wave observatory? Is it complete? ”

Zhang Qing's eyes lit up, although his own Tianqin plan and Ali plan are also underway in gravitational wave research, it is undeniable that Ligo in the United States has been ahead of him.

If the complete data of the Ligo project can be obtained at this time, even if Ligo is a ground exploration Tianqin program and Lu Yi's plan is a space exploration, it will also play a qualitative improvement in the research of the entire space gravitational wave project.

Even from a certain point of view, the noise interference of the ground environment will be greater, and the detection will be more difficult.

"Complete, including the last time they discovered the determination of gravitational waves."

Lu Yi smiled, he only mentioned this matter tentatively, but he didn't think about it, and even the original plan to make concessions from cancer suppressant drugs in exchange was waived.

"I'll look for Rupert first, you can ask Principal Luo about this matter, and see if there is anything that needs to be piggybacked on the Tianqin Project, and the autumn wind that has been playing the Tianqin Project for so long should also be reported."

"Well, I know, it seems that if I go to Baidao City in the future, the professors won't see me, and I won't have a good face."

Zhang Qing also smiled, limited by the fact that the research conditions for space gravitational waves on her side were not yet available, during this time, she went to Baidao City under the banner of the national attack of the controllable nuclear fusion project, and asked for some data from the Tianqin Project with her former mentor and President Luo of CUHK, and then began to slowly establish her own research.
