"Now is the most dangerous time."

"The emergency system test is the riskiest one, as the power supply is cut off, and the power of the light-pressure engine is greatly reduced in an instant."

"If something goes wrong, the engine is likely to hit the support rod, break the fixtures of the support bar, and maybe even hit the ground directly......"

Xiang Qiansheng's explanation scared Mr. Zhu into a cold sweat.

He was starting to worry again.

Although the light-pressure engine is close to landing, it will not cause major damage to other positions, and it will not cause large-scale accidents, but the damage to the light-pressure engine itself will also be a major loss.

This big guy has spent more than 100 billion yuan, and it also contains the efforts of many scientists and countless people.

Teacher Zhu knew that he couldn't stop it, so he could only silently pray that the test would go smoothly, "Don't go wrong!" ”

"Surely there will be no problem!"

"Everything will go well, Academician Wang is not worried, but ...... Of course he wasn't worried, and he couldn't be held accountable anyway. ”

Mr. Zhu was depressed and wanted to cry, why would he be held accountable for research that had almost nothing to do with him?

It's not fair!

"It seems that I should consider retiring early, there is a space test below, I am this age, I can't help but be so frightened!"

At this moment, the live broadcasts of various TV stations pointed to the light-pressure engine, which was about 30 kilometers away, and they could still see half of the ball from the perspective of the hillside, and they also knew that the engine was landing.

Now the speed of the engine circuit is very slow, and the camera lens barely moves.

But everyone knows that landing is dangerous.

Landing is often much more dangerous than taking off, because take-off is just flying, and the air will not bring any collision to the aircraft, but the landing is likely to collide, and many aviation disasters occur during landing, especially the moment the aircraft lands, the danger factor is higher.

Not to mention, the big guy in front of you.

This big guy of more than 10,000 tons, as long as there is a little collision during the landing process, it will cause huge losses, and may even bring huge accidents.

At the same time, the engine was being prepared for emergency tests.

The engine hovers about 30 meters above the support rod, as if to explain to Qiansheng, the engine will disconnect the solar magnetized power supply system, and the emergency system will deploy the superconducting battery to support the power supply.

The change in power supply will cause the power supply to be temporarily unstable, resulting in a momentary decrease in power.

That's where the danger lies.

If there is a problem during the test, the engine is thirty meters away from the support rod, and falling to the support position may hit the ground under inertia and huge weight, but it will not cause much disaster, of course, the support rod including the outer layer of the concave mirror collides, and the equipment damage is unavoidable.

Control.

Zhu Qiqiang received the data and then reported, "The engine is 32 meters away from the support rod and is currently running smoothly." ”

Wang Hao asked, "How is Zhang Wei?" ”

"Connect the cabin!" Zhu Qiqiang shouted, and then the voice was connected to the cabin above the engine.

Zhang Wei immediately said loudly, "Report, everything is normal!" Zhang Wei is ready! ”

He knows what's next.

This moment is also very dangerous for him, and the danger of emergency problems is not great, because even if there is a fall collision, the cabin is still safe at the top of the engine.

The most feared thing is a big accident, for example, an explosion.

If there is an explosion and the cabin above is also affected, then he doesn't even have a chance to escape, even if it is an ejection seat, it is meaningless, the high-pressure engine is too big, and the ground is full of high temperatures, it will definitely be affected by the high temperature if it is ejected, it is better to stay in the cabin, maybe if you are lucky, you will escape the catastrophe.

Of course, that's a very special case.

After Wang Hao heard Zhang Wei's answer, he nodded and ordered, "Let's start!" ”

The operator was ready, he immediately pulled down the emergency test lever, after the lever was pulled down, the engine received the control information, the functional magnetization power generation equipment was instantly cut off the light source, and the power generation equipment instantaneously supplied electric energy to zero.

This is not a gradual process, but a simulation of a breach or major failure that directly cuts off the power supply.

When the power supply is reduced to zero, the emergency system is instantaneously turned on, and the superconducting battery is allocated to increase the output power.

At the moment of power supply conversion, there is a fault in the power supply, which does not mean that there is no power supply at all, but a process in which the power supply is greatly reduced, and then returns to normal state.

At that moment, it was obvious that the engine trembled, and then there was even a tendency to fall directly.

If it was a small thing, it would not matter if it trembled, but such a huge light-pressure engine trembled, and suddenly everyone's hearts were tugging.

Those who watched the live broadcast in front of the TV were stunned for a moment.

"What's going on?"

"It seems that something went wrong just now, and I saw the engine suddenly drop?"

"There was a shock, was it an accident?"

"It can't be an accident, right? I can't see what's going on down there from this angle, but I guess I haven't landed yet, right? ”

Many people were stunned.

Some of the TV hosts didn't know what was going on, all they saw was that the big ball trembled, then seemed to drop a little, and then shook a few times before regaining its calm.

The host of the domestic TV station has a direct information channel, and he immediately received a prompt to explain, "It was not an accident just now, it was a test of the internal emergency system, and the test will cut off the internal power supply, resulting in a momentary drop in power." ”

"Now the engine is smooth again, so we can be sure that the test has been successful!"

Soon, the other hosts also knew the news, and let more viewers in front of the TV know the reason.

"It turned out that it wasn't an accident, it was a test!"

"I thought I saw some big accident, but it turned out to be a success, but fortunately it didn't happen."

"It seems that there is no problem, the test is over."

"It depends on the situation, it has dropped a short distance, and the emergency system guarantee is still very good."

"The next step is to actually land, it should be over."

The next step is indeed landing.

However, before the landing begins, each section also reports the data after the emergency system is turned on, including the temperature inside the concave mirror, the output of the neutron channel, the power supplied by the superconducting battery, and the operation, etc.

They need to compare emergency data with routine data.

Once everything was decided, the next step was to land, and this was not the first time they had landed, but the third time they had also conducted a take-off and landing test in the middle of the study.

After two experiences, the operator was calm about the landing mission.

At this time, Mr. Zhu finally regained his composure, he clutched his chest hard, and a smile appeared on his face.

He turned his head to look at Xiang Qiansheng, suddenly frowned, and thought of a strange question, "Why is this guy so calm the whole time?" I don't seem to be worried at all, something is wrong! ”

Teacher Zhu couldn't help but ask, "Professor Xiang, didn't you say it's dangerous?" Why aren't you worried? ”

Xiang Qiansheng said, "I'm really not worried. ”

"Huh?"

"It was dangerous, but the likelihood of an accident was low." Xiang Qiansheng explained, "Didn't Academician Wang say it? The success rate of this test is very high, more than 95 out of 10. ”

"Even if we are nine out of five, there is only a 5% probability of a problem, and 5% is still the probability of a problem for all tests, and when it comes to the emergency test, the probability of occurrence is less than 1%."

He continued, "This is still an overestimate, I think the probability of a problem is less than 0.1%, a 1 in 1,000 probability, so why worry? ”

“……”

Teacher Zhu pursed his lips vigorously after hearing this, he wanted to say something to refute it, but found that what the other party said was very reasonable, and he couldn't refute it at all.

In other words, he was worried about it in vain!

……

Landing, success.

Test, over!

The success of the high-altitude test was indeed very exciting, and many people in the control room cheered.

After the light-pressure engine has completed the high-altitude test, the next step is to prepare for the space test, and the completion of the high-altitude test is equivalent to entering a new stage, and the space carrier can even start to demonstrate.

Whether it's the success of the test, the new phase of the research, or the vision for the future, they have every reason to be happy.

Wang Hao was also very happy, he shook hands and hugged several people, and enjoyed the joy of success with everyone.

However, the work is not over yet.

After the high-altitude test, they will conduct a detailed inspection of the inside and outside of the light-pressure engine, and the inspection process will last one to two weeks, and any problems found in the middle will be solved.

Now is also the end of the moment, Wang Hao celebrated with everyone for a while, looked at the time and walked out of the control room, and asked Zhu Qiqiang, "Zhang Wei, how is it?" Did you get it? ”

"It's not down yet, but it's about the same time."

Zhu Qiqiang said.

After the light pressure engine landed, Zhang Wei could not get out of the cabin as soon as possible, because the temperature outside was too high, the air was very stuffy, not to mention, the temperature of the outer ladder of the engine was more than 100 degrees, and the ground below even exceeded 200 degrees.

In order to ensure absolute safety, he received the message half an hour later before opening the hatch above.

At this time, a helicopter hovered in the air and threw down the ladder right in front of the hatch, Zhang Wei tied the rope to his body, and after making sure that there was no problem, he signaled that the helicopter could leave.

He was hoisted about five kilometers away by a helicopter before descending up and down a hillside, where a car was already waiting.

Soon Zhang Wei met Mr. Xu and his party.

Teacher Xu patted Zhang Wei on the shoulder and asked, "How do you feel about this mission?" ”

"It's easy."

Zhang Wei's answer was very calm, he showed a relaxed face, and said with a smile, "The oxygen supply system in the cabin is very stable, and I have never worn a mask. ”

It was really easy for him this time.

Because the oxygen supply system in the cabin is very stable, he doesn't even need to wear an oxygen mask, and when flying a fighter jet, he has to wear an oxygen mask all the time.

In addition, the acceleration of the light-pressure engine is very slow, the acceleration of several meters per second is not even able to catch up with the car on the road, and he sits in a seat with very high stability, and he doesn't even feel anything.

In comparison, the acceleration of a fighter jet is too fast.

If the fighter is performing a show mission, it also needs to perform a variety of tense maneuvers, including but not limited to vertical flight, inverted flight, extremely fast falling, and so on.

In the process of the light pressure engine test, the only thing I feel is the rapid fall, but the fast fall is not a free fall, but just a faster deceleration, so to speak, there is still no feeling.

This mission was too easy for Zhang Wei, who sat entirely in his position for two hours, and was even in the mood to interact with the animals halfway.

Then, it's over.

……

The end of the high-pressure engine test is not a celebration, but a targeted working meeting.

The follow-up testing work in the general direction has been assigned.

Wang Hao and Zhu Qiqiang, Cao Dongming and others discussed, and they found out several key detection positions according to the data fluctuations in the test process, and explained several groups at the meeting.

After the meeting, Wang Hao and the leading group talked about the next step.

"The priority is fundraising."

"We expect to raise 150 billion yuan in the next step, including the design, early construction, research and development of key technologies for the aerospace carrier, and the installation of weapon systems for the engine, which is very important and a necessary preparation for space testing."

Mr. Xu asked, "Is the weapon system going to be installed now?" I've heard that it's laser weapons. ”

"Yes!"

Wang Hao said, "Laser weapons are the most suitable for light source engines, and we have reserved more than 100 active ports on the concave mirror to ensure that they can carry out more than ten strikes in the same direction and the same position in an instant, covering a minimum distance of more than 3,000 kilometers." ”

"It's the basics."

"In space, 3,000 kilometers is not too far, and laser weapons are also in space, so they can have the greatest effect."

If the laser weapon is used on the ground, the distance and power of the strike will be greatly reduced, because the dense air and dust will greatly reduce the power of the laser.

Wang Hao continued, "When the engine is tested in close proximity, we have enough ground weapon support to protect it, but in space it is different. ”

"Even a small satellite can pose a serious threat to the engine."

"The speed of the space satellite is so fast that even if it is detected in advance, it may not be too late to react."

"So you have to have protective weapons to ensure safety."

"We are ready to install enough laser weapons before the next test, which can ensure that all possible dangers are strangled in the cradle!"
