A big country of aerospace with black technology

"With no working medium propulsion method, the future technological prospects are very bright."

"After all, it is still difficult to replenish supplies in space."

When Zhang Xingyang made his concluding remarks, he first praised the lack of progress.

However, after hearing the praise, those who originally advocated the use of propellant-free propulsion, represented by Zhou Xuan, became heavy-faced.

Everyone understands the principle of restraining before promoting.

As soon as Zhang Xingyang came up, he praised the no-material propulsion, and everyone present understood what he meant.

"However, the technical reserves we have accumulated in terms of fluid-free propulsion are not very sufficient."

"It is still difficult to come up with a mature propulsion solution without working fluid based on our current technology."

"So, we should still adopt a working fluid propulsion solution in the early stages of deep space exploration."

As the top rocket expert in the country today, Zhang Xingyang's words can be said to have brought the final conclusion to this meeting.

In the end, he supported the refrigerant propulsion plan.

Although her plan was rejected, Zhou Xuan still took the lead in applauding.

After all, the Deep Space Exploration Institute is currently conducting in-depth cooperation with the Rocket Academy on asteroid exploration.

Although the two sides have differences on the future deep space propulsion methods, at the current stage, everyone can still work together happily.

After all, deep space exploration is at least twenty or thirty years away.

After the meeting, Zhang Xingyang found Zhou Xuan and chatted about the future development of refrigerant-free propulsion.

"Actually, if it were another thirty years later, I would definitely support propulsion without refrigerant."

Zhang Xingyang revealed his true thoughts as soon as he opened his mouth.

Propulsion without working fluid is not a bad thing. In the future, propulsion without working fluid will be a very popular method of space navigation.

However, at this time, it is too early for everyone to advance without working fluid!

"We have too little research on fluid-free propulsion right now."

"Even the EM engine is not finished yet."

Zhou Xuan's expression didn't change much after listening to the first two sentences.

It wasn't until Zhang Xingyang mentioned the EM engine that he had never heard of before that he frowned.

"What is the EM engine?" Zhou Xuan asked directly.

"Haven't you heard of it?"

Zhang Xingyang didn't react at the first moment, and it took him half a second to realize that the EM engine had not been officially discovered yet.

So he opened his mouth and explained:

"This is an interesting phenomenon that we have discovered before."

"I wonder if you are interested."

Zhou Xuan didn't directly say that she was interested, but she still raised her eyebrows.

"We used a microwave transmitter and a copper cone-shaped reflection cavity in the laboratory before, and found that when we inject microwaves into the cavity, we can generate thrust in the direction of the bottom of the cavity."

"In the laboratory, we used 30 kilowatts of microwaves to produce 120 millinewtons of thrust."

120 millinewtons, this seemingly inconspicuous number, may only be able to hold up an A4 paper on the earth.

But in the universe, such a thrust is actually not too small.

Take the Hall thrusters on the space station as an example. Each of the advanced Hall thrusters on the Tiangong Space Station can only produce 320 millinewtons of thrust.

The power generation efficiency of the space station is about 120 kilowatts, which means that with the same power, the EM engine can reach a thrust of 480 millinewtons!

"How can this be?"

Zhou Xuan finally showed a shocked expression at this time.

"This does not comply with the conservation of momentum!"

Indeed, at first glance it does appear to be so.

But in fact, momentum is still conserved, but the entire system is larger than Zhou Xuan thought.

Zhang Xingyang did not say this. In fact, their research institute has not conducted research on EM engines.

The EM engine was not discovered until the following year, in 2003, by a John Bull engineer.

"We find this very strange."

Zhang Xingyang spread his hands and said.

"However, we were understaffed and did not conduct additional follow-up studies."

"I wonder if Dean Zhou is interested in conducting research together."

"We also want to know why this phenomenon occurs."

Although Zhou Xuan is the director of the Deep Space Exploration Institute, she also has a technical background and is not completely ignorant of technology.

Otherwise, he would not have been able to realize immediately that there was a problem of non-conservation of momentum.

"I have a lot of interests."

Zhou Xuan herself is indeed very interested in this special phenomenon.

"However, many people in our institute are currently busy preparing for the asteroid exploration plan with Gaul, and they can't get away from it."

At this time, after several months of preliminary preparation, as part of the joint exploration plan.

The asteroid exploration program has also officially begun.

The two sides are conducting preliminary coordination on personnel.

Some domestic scientific researchers need to travel to Gaul to work.

Similarly, domestic scientific research institutes must also be prepared to receive a group of scientists and engineers from Gaul.

Zhou Xuan currently does not have many manpower capable of carrying out this scientific research task.

“There’s no rush on this project.”

"We should be the only ones who have discovered this phenomenon so far."

"Otherwise, it would have caused an international uproar."

"So we have enough first-mover advantage and time."

"However, this project must pay attention to the issue of confidentiality."

Zhang Xingyang is very optimistic about the future of this project.

After all, if the original historical development is followed, our side will have at least two years to conduct sufficient research.

But you still have to be careful not to make any noise.

It is best to make a fortune quietly.

"I understand all of this."

This is not the first time Zhou Xuan has carried out confidentiality work. He is very clear about the precautions in this regard.

"But I still can't figure out why such a strange phenomenon can occur."

Zhang Xingyang can naturally understand that such a phenomenon can break many people's concept of momentum conservation.

However, he did not explain much about why such a phenomenon could occur.

In fact, during his time, EM engines were as common as lighters today.

It is a very popular civilian industrial product.

"We need to find out through research."

"At least now, I don't know why."

Zhang Xingyang looked at Zhou Xuan who was still bowing his head in thought in front of him, smiled and said.

"Maybe it's a special kind of scene, maybe?"

What Zhang Xingyang said was not wrong, but it did mislead Zhou Xuan's thoughts.

"field?"

After Zhou Xuan repeated it, she fell into thinking again. (End of chapter)
