Chapter 2729

Well, they can see that Qin Luo is playing from the beginning, really.

"Yes

Silence for a long time, Zhou Minggang heavily nodded.

There's no way. Seeing Qin Luo's appearance is that he has decided to change his mind?

Emmmmm, forgive them for reading less. They really don't have this ability!

Looking at the people's appearance, Qin Luo's face was filled with a brilliant smile and said, "professors, there is one more thing."

"Derailment technology is divided into active and passive derailment. Which do you think we should try first?"

Derailment is not a matter of simple opinion.

He is divided into active and passive.

The conditions to distinguish between the two are also very simple.

Whether they have the ability to change tracks.

The spacecraft with the ability of orbit change can be directly provided by the engine, which means that the spacecraft will actively fall into the atmosphere after leaving the original orbit.

The spacecraft without active orbit transfer capability needs special brake rocket.

The brake rocket is installed on the spacecraft along the longitudinal axis, so that the thrust vector of the rocket is consistent with the longitudinal axis.

Firstly, the attitude control system adjusts the attitude of the spacecraft to make its longitudinal axis form an angle θ (called braking angle) with the local horizontal plane, and then the longitudinal axis direction is called the braking direction. The thrust of the braking rocket acts along the braking direction for a period of time, which makes the spacecraft obtain an additional velocity Δ V in this direction.

Therefore, the velocity of the spacecraft changes from V1 to v2. Although the magnitude of V2 and V1 changes little, the change of direction can make the spacecraft leave the original orbit, so as to achieve the purpose of landing.

Compared with passive orbit change, the maneuverability of active orbit change is undoubtedly much better.

But correspondingly, the difficulty of the project is much higher.

It usually takes several times as much time as the passive orbit transfer research.

If it's normal, Zhou Minggang thinks it's better to take the initiative to change track.

But the current situation is that time is extremely tight.

For Qin Luo, there is not much time left for them.

Simply put, they don't have time to complete the active orbit transfer experiment.

So for Zhou Minggang, the multiple choice question is not without solution.

After a little meditation, Zhou Minggang immediately said, "if you want to ask me, I suggest that we should focus on the passive transformation."

"After all, time is tight. If we want to complete the manned space flight test within half a year, we must seize all the time."

"Moreover, everything should be simple and start from the most practical and time-saving topic. Only in this way can the test flight be completed in half a year!"

I have to say that Qin Luo thinks Zhou Minggang's words are quite reasonable.

As he said, time is pressing now, Qin Luo has no time to spend here.

However, it does not mean that Qin Luo will do so.

As a learning bully, and is the world's top academic bully.

Qin Luo has his own principles.

That is to do it or not, to do it, to be the best.

In any case, both sides need to be experimented, so why not do it in one step?

Isn't it a waste of time to study it again later?

"Professor Zhou, what you said is very reasonable." Qin Luo nodded solemnly on his face and said, "however, I don't intend to adopt it."

Zhou Minggang:???

What do you mean?

I think what I said is reasonable, but I just don't use it, right?

Zhou Minggang is the first time to see someone playing like this!
