Chapter 709

When people saw this main design drawing, they were stunned by the contents above. No matter from which angle to observe, it is impeccable. Even a little more careful, you can see an unexpected picture.

"Ah?"

"No Feng, who is in charge of the rocket part, found that the standard of this drawing is not the Chinese standard, but the American Standard. It is reasonable that Xu mang could not have made such a mistake and made a mistake in the standard.

Unless...

the main design above is NASA's curiosity master design.

"This..."

"isn't this the design of NASA curiosity?" "The standards above are completely different from ours. I don't believe that Professor Xu mang did this on purpose, unless this is the design drawing of NASA's curiosity Rover."

As soon as the voice drops,

the conference room is like boiling water, and it boils up in an instant.

Everyone, including Zhang Ju, looked at Xu Mang, hoping that he could give a reasonable explanation of how NASA's Mars rover design drawings appeared in his hands.

"Cough!"

"It was a beautiful accident." Xu mang said with a smile: "I forgot what I used in exchange for... Oh! By the way, the Xu Yang structural formula that I found, with an extended equation of this formula, was replaced by the NASA design of the Mars rover curiosity. "

“？？？”

“？？？”

“？？？”

This... This...

is this a loss or a gain?

Xu Yang's structural formula, as everyone here knows, is a Nobel class discovery. However, Xu Mang, who is more than a chicken thief, has been holding his hand and not publishing it. However, it is because of this situation that he has changed to many important technologies.

But...

in private, he even changed to NASA's curiosity Rover design drawings. It's hard to imagine that the United States should have been cheated by Xu mang once. They didn't believe in evil and proposed to replace Xu Yang's structural formula.

"The process..."

"I will not elaborate here." Xu mang embarrassed and not disrespectful appearance said: "anyway, at that time to give them enough gas, there is the story of the back to the aerospace engine."

Everyone gave a bitter smile. It was really the case.

"What..."

"I have a showdown. The Mars rover Bajie was copied from curiosity, but don't worry... It has its own property right completely!" Xu mang said with a smile: "the United States, they dare not speak, can only admit that we are our own R & D, in any case, it is my R & D line."

Then, Xu began to introduce the main functions of the Mars rover Bajie.

"In terms of hardware, I specially used the chip processor developed by my father-in-law, which can provide powerful computing power. Of course, in the future, I will use the system I specially developed, which is the real-time operating system used in a large number of embedded systems."

"The designed service life is two Mars years, but it should be more than that. In terms of ancillary equipment, the design is completely in accordance with the specifications given to me by the space agency. In addition to the deceleration parachute and heat shield, I replaced the power source with a multi mission radioisotope thermoelectric generator."

"About 30 years of service life... This part is mast camera, Mars hand lens imager moved to this position, the original lens imager position was changed to Mars landing imager, and at the end of the manipulator arm, it was alpha particle roentgen ray spectrometer."

"This position..."

Xu mang talked for half an hour, and he did not let go of every detail. All the people present were shocked by the eight commandments Mars rover and conquered by Xu Mang's incomparable transformation ability.

At the end of the speech,

Xu mang was about to drink water, but academician Jin found him with doubts.

"Professor Xu mang?"

"I have a look... The weight control is very good, but after careful calculation, it seems that the weight is 5000 grams less." Academician Jin said: "in the middle of the rover, such a good space is empty, isn't it... This position is for the self rescue program?"

Xu mang took a sip of water, nodded and said, "yes! It's the self-help program. "

The next second,

Xu opened another file.

"In general, nine out of ten accidents are fast, but when the car overturns on Mars, it's basically cool." Xu mang said with a smile: "although the center of gravity has been reduced to the lowest under my design, it is difficult to cause capsizing as long as there is no Mars storm."

"But... If there's a rollover, it's probably a meteorite impact, geological activity, alien life, or even transformers." Xu mang said seriously, "but if we go back ten thousand steps, I can't do anything about it."“？？？”

“？？？”

“？？？”

This...

How can this help itself?

When the fire face confused, Xu mang flipped the page, a central processing system appeared in front of everyone.

"This is a data processor developed by me, which can systematically analyze the surrounding things, and is the last security guarantee of the eight commandments." "It can automatically calculate the height drop and angle, and reasonably plan a safe route," Xu said

"I'm sorry..."

"NASA didn't give me the design concept of self-help program, it was all my own imagination." Xu mang helplessly said: "once the rover capsized, there was basically no rescue. There were all valuable instruments on it. If you hit it, it would be useless."

"So!"

"Safety lies in prevention." "Once the self-help program of Bajie sensed the danger, it would intervene and finally get out of danger," Xu said

After a look at the audience, Xu found that they were silent and their eyes were fixed on the projection.

"Good!"

"This system is very important!" With his keen intuition, Zhang Ju said seriously, "can Professor Xu mang... Give us this patent in the future?"

"Take it away!"

Xu mang said with a smile: "I have no place to use anyway."

After that, Xu mang regretted and said in a hurry: "wait... It can be used, but the patent is mine!"

Zhang Bureau smiles: "did you find any business opportunities? Can it be used in cars? "

"I'm sorry..."

"I want to support my family. My wife is a shrew. If she knows such important skills to others, I'm afraid I'll be beaten when I go home." Xu mang directly threw the pot to Xiaoman, but she was not there.

"..."

"..."

"..."

"..."

I dare to say!

It's a pity to get married so young.

"Below."

"It's about the design of the sky crane and landing." Xu opened the third document, then raised his head and said, "I didn't get the relevant drawings for the design of sky crane. I designed it according to the photos of NASA."

However,

this remark has touched the heartstrings of all people. If what Xu mang said is true, then this technology is not so mature. Immature represents danger, which is different from self rescue program. Self rescue program is only computer program, but sky crane is mechanical equipment.

In case of any problems, there is no time to operate, so during the period from entering the atmosphere to landing, it is in black for 10 minutes, and the sky crane operates by itself.

If one of the details is not done in place, the result will be a crash and the investment of 10 billion yuan will be wasted.

"We need to reduce the speed from 20000 kilometers per hour to 0.5 meters in ten minutes..." Xu said calmly, "so the sky crane must be combined with the No

"At a certain height from the ground, the cable will be automatically cut off, and sky crane will then land within a certain safe distance from the No.8 ring." Xu mang said: "it's probably like this. In fact, the sky crane is OK."

"This... Process is very troublesome." Xu mang did not want to hide the truth, but said: "we need to successfully complete a series of actions, including the use of parachutes to slow down and ignite rockets to prepare for landing, so as to reduce the speed of a three ton lander, including the Mars rover, from bullets to a smooth landing."

"It has to execute hundreds of programs and 700000 lines of code accurately. If one of them is wrong, the rover will probably crash on the surface of Mars and smash to pieces."

As the saying goes,

all the people present turned pale.

This program will not be fatal, hundreds of thousands of lines of code?

"I don't agree!"

"It's too risky!" Academician Qian said seriously: "Professor Xu mang... I'm not doubting your ability. You've been very amazing, but people will make all kinds of mistakes. What if you make mistakes?"

For this view,

Xu mang had no power to refute this view. After pondering for a long time, Xu mang said: "I admit that this process is very dangerous. If we are not careful, accidents will occur, which will lead to the collapse of the whole plan, and everyone will fall into the pressure of public opinion. However, NASA also encountered the problems we encountered at the beginning."

"Why can they?" "And we can't," Xu asked? How about the landing mode of the rover, you can show it to the public, and then push me down in front of the public. Even if there is a problem, I can carry it alone. ""..."

"..."

"..."

"..."

looking at Xu Mang, Zhang Ju solemnly said: "you won't be allowed to face all this alone. As a whole, you have to bear the consequences together. But what you just said made me very touched. The road of aerospace development is full of unknowns. Who doesn't know what will happen next."

"To be honest..."

"we're a little bit withdrawn." Zhang bureau took a look at all the people present and said with a bitter smile: "isn't it normal to fail? In the past, we could face failure. Why not now? "

"About landing mode."

"Officially using Sky Crane mode, Professor Xu mang... The program code problem behind, still depends on you to solve." Zhang Bureau solemnly said: "boldly rest assured to do, what's wrong, all people shoulder together!"

"But..."

"I have a request." Zhang Ju said with a smile: "Bajie is too bad to hear, change a name!"

Xu mang pondered for a moment and said cautiously, "white cat?"
