"Without working fluid propulsion, the future technology prospects are very bright."

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

When Zhang Xingyang made a concluding statement, he first praised the non-working substance advancement.

But when he heard the praise, the people who originally advocated the use of non-working fluid for advancement, represented by Zhou Xuan, turned heavy on the contrary.

Everyone understands the truth that if you want to promote and suppress first.

As soon as Zhang Xingyang came up, he praised the non-working fluid, and everyone present understood what he meant.

"However, the technical reserves we have accumulated in the field of work-proof propulsion are not very sufficient."

"If we want to come up with a mature work-free propulsion plan, it is still difficult to see our current technology."

"Therefore, in the early stage of deep space exploration, we should still use the working fluid propulsion scheme."

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

In the end, he supported the solution of working fluid propulsion.

Although his plan was denied, Zhou Xuan still took the lead in applauding.

After all, the Institute of Deep Space Exploration is now carrying out in-depth cooperation with the Rocket Research Institute on asteroid exploration.

Although there are differences between the two sides on the way to propulsion deep space in the future, at this stage, everyone can still work together happily.

After all, deep space exploration will be at least twenty or thirty years later.

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

"In fact, if it were another thirty years later, I would definitely support the advancement of work-free fluid."

As soon as Zhang Xingyang opened his mouth, he said what he really thought in his heart.

Non-working propulsion is not bad, and in the future, non-working propulsion will be a very popular way of space navigation.

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

"There is so little research on work-free propulsion right now."

"Not even the EM engine was done."

Zhou Xuan's expression did not change when he finished listening to the first two sentences.

It wasn't until Zhang Xingyang mentioned the EM engine that he hadn't known about Yugu before, that he frowned.

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

"Haven't you heard?"

Zhang Xingyang didn't react at the first time, and it took half a second to react, and now the EM engine has not been officially discovered.

So he opened his mouth and explained:

"This is an interesting phenomenon that we found before."

"I don't know if you're interested."

Zhou Xuan didn't say that he was interested, but he still raised his eyebrows.

"We were in the lab using a microwave emitter and a copper conical reflector and found that when we injected microwaves into the cavity, it generated thrust in the direction of the bottom of the cavity."

"In the lab, we produced 120 milliN of thrust with a 30-kilowatt microwave."

120 milliN is an inconspicuous number, and it may only hold up a piece of A4 paper on top of the earth.

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

Taking the Hall thrusters on the space station as an example, the advanced Hall thrusters on the Tiangong space station can only produce 320 milliN of thrust each.

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

"How is this possible?"

Zhou Xuan finally showed a shocked expression at this time.

"This is not in line with the conservation of momentum!"

Indeed, at first glance it does seem so.

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

Zhang Xingyang didn't say this, and in fact, their research institute did not conduct research on EM engines.

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

"We think it's weird."

Zhang Xingyang spread out his hands and said.

"However, we are understaffed and have not conducted further research."

"I don't know if Dean Zhou is interested in conducting research together."

"We also want to know why this is happening."

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

Otherwise, he would not have been able to react to the problem of non-conservation of momentum in the first place.

"I have a lot of interests."

Zhou Xuan himself is indeed quite interested in this special phenomenon.

"But many of us are currently busy preparing for the asteroid exploration program in Gaul, and we can't get out of it."

At this time, after several months of preliminary preparation, as part of a joint exploration program.

The asteroid exploration program has also officially begun.

Preliminary personnel coordination is underway between the two sides.

Some of the country's scientific researchers need to travel to Gaul to work.

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

Zhou Xuan doesn't have much of the manpower to carry out this scientific task now.

"This project is not in a hurry."

"This phenomenon should be the only one we have discovered so far."

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

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

"However, this project must focus on confidentiality."

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

After all, if the original historical development is followed, there will be at least two years left for your side to conduct sufficient research.

However, you still have to be careful not to make a statement.

It's best to get rich quietly.

"I understand all of this."

It is not the first time that Zhou Xuan has carried out confidentiality work, and he is very clear about the precautions in this regard.

"But I still don't understand why such a strange phenomenon can occur."

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

However, he did not explain much why this phenomenon could occur.

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

It is a very popular civilian industrial product.

"That's something we need to do our research to find out."

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

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

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

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

"Field?"

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