Scholar’s Advanced Technological System

New Year's Day.

Regardless of whether or not you understand aerospace, almost half of China is excited about the launch of the auspicious. The average person may not understand the difference between electric propulsion and chemical propulsion, and does not know what the Hall propeller is. However, as the first space plane that can safely travel to and from the surface and outer space, the auspicious can be said to fill the Chinese This piece is blank.

However, in this happy day, a report suddenly released by The New York Times poured a cold water on many people who were still excited.

In the report, the New York Times selected a part of the nasa spokesperson's remarks for processing, and cited several views of other aerospace engineers in Silicon Valley, saying that the auspicious name has serious flaws in design.

And this fatal flaw may make it difficult to get up and down.

The final result is likely to disintegrate in the atmosphere like the Columbia...

This interview has just been released, and it has been widely debated on social media such as Twitter and Facebook.

When the report of the New York Times was sent back to China, it was a big shock. In particular, the video of the New Year's Day, which coincided with the 25-second period, just came out, and suddenly overwhelmed the overwhelming report on the successful launch of the Xiangrui.

Excitement is not exciting.

Even a lot of people have squeezed sweat for Professor Lu, who is still in the sky.

【paralysis! The United States is uneasy! Watching our plane go up, curse it and fall! 】

Can the plane be cursed? This is also a good reminder! 】

【not necessarily! I think this American cockroach is definitely premeditating. Wouldn't it be that you want to secretly hit it with a missile? 】

[Mig-25: As long as I run fast enough, the missile can't catch up with me (funny)]

[Blessing for the Lushen (candle) (candle) (candle)]

[I wish to use the above singles for a single life for the auspicious land landing safety (candle)]

[...]

Related topics were quickly whipped up.

Also lost this time Lu Zhou can not play the phone, can not brush the collar, otherwise it will certainly not help laughing out.

Can't return?

How can it be……

Retreat 10,000 steps, even if it really can't return, there is a spare escape cabin to use, how can he not really make fun of his own life.

At this moment, it is far above the height of four hundred kilometers.

The auspicious squad running in low earth orbit has completed a series of basic operations including orbital flight, pressure regulation in the spacecraft cabin, standby sanitary system test, sleep in weightless environment, eating, etc., and 20 cases of fruit and vegetable seeds Under the space environment, observe the possible effects of cosmic rays on life activities.

After completing a series of flight tests and scientific expeditions, the cruise time has reached 23 hours and 50 minutes.

As planned, the Xiangrui restarted the engine under the direction of the ground command and prepared for the return flight.

Sitting in the co-pilot position, Nie Wei checked the operation of the energy-supplied parts while imitating the voice of the flight attendants.

"Professor Lu, please wear the spacesuit in the cabin and then lie on the passenger seat. The flight will be back soon..."

"I know, don't remind me." Lu Zhou smiled and said, pointing a thumbs up at both of them. "Good luck, please come back when you return."

At this moment, his mood is quite good.

This time, God is overdue.

Of course, the most important thing is the 50,000 free experience and lucky draw chance.

Even if it is for the 50,000 free experience, the cost of flying this test will not be lost.

Nie Yun turned back and smiled a bit, but the palm of his hand had already oozing sweat.

The difficulty of returning is not less difficult than launching.

Although in theory the auspicious return strategy is much safer than the average re-entry spacecraft, no one can guarantee that there will be no accidents. After all, he and Xiangrui are both flying so high for the first time...

"Professor, can you promise me something?"

Lu Zhou: "What is it?"

"If this time, returning safely..."

"Hold it!" Lu Zhou hurriedly raised his hand and interrupted Nie Yun’s words. "I will not rush to set the flag at this time. I will promise you after waiting for the ground."

Just don't overdo it.

Don't rush to marry.

However, Nie Yun did not appreciate it.

Seeing that Lu Zhou was obviously perfunctory, his hands suddenly left the console and said with a look of anger.

"No, I must say it now!"

Lu Zhou: "..."

Mmp!

A big man can't wait for an hour or two?

Sighed, Lu Zhou reluctantly opened.

"Well, then you said, but if you speak now, I don't guarantee that I will promise you anything."

Nie Yun: "My request is very simple, promise me this is the last time!"

Upon hearing this, Lu Zhou suddenly looked constipated.

How can this be!

He still has a long life!

Looking at the resolute expression on Nie Yun’s face, Lu Zhou reluctantly compromised.

"I promised you the most, this is the last time you took your plane to heaven."

Nie Yun thought for a moment and barely nodded.

"also!"

Anyway, just don't be on his plane.

If Nima had an accident, it would have been nailed to the shame of history.

After joining the army for so many years, he was so afraid of death for the first time.

"Well, brother, you are enough!"

Nie Yan shook his head and reached for a few buttons on the control panel.

"The navigation system has been started, confirming that there is no abnormality in the navigation channel, the energy supply device is warmed up, and the No. 1 and No. 2 engines are on standby."

"The orbit is ready."

Restoring the usual calmness and calmness, Nie Yun took a deep breath with his eyes closed and opened his eyes again.

"ignition!"

......

Whether it is a space shuttle or an aerospace plane or any other manned spacecraft, returning from low earth orbit is always a technical activity.

As a co-pilot, Nie Wei first determined the "fuel" status of the auspicious. Among them, the remaining amount of 氘氚 mixed gas is quite sufficient, even if it is more than once to return to the surface, the only loss is the solid enthalpy in the working compartment, leaving only 21% of the balance.

After all, there is no certain thrust that can't climb the gravity well. If you want to fly from the surface to the low earth orbit, you must increase the amount of the working fluid to increase the thrust of the engine at the expense of a certain specific impulse.

However, if it is just a return flight, this work is more than enough.

Under the dual guidance of the ground command and the spacecraft intelligent navigation system, Nie Yun controlled the auspicious success of the orbit and entered the transitional orbit from the running track.

At the same time, Nasa's satellite control room, the sound of the amazement sounded in front of the semi-arc console.

"The target starts to return."

"May the Pacific Ocean be their destination," staring at the green dot on the screen. Aiden added a vicious addition to the sentence. "In addition to the spacecraft, it is best not to leave the whole body." ”

Several workers who monitored the movement of the spacecraft frowned and twitched.

For the astronauts, this curse is really vicious.

Even for competitors...

Staring nervously at the green spot near the dense boundary of the atmosphere, the engineer sitting in front of the console suddenly said.

“The movement track of Xiangyun is abnormal...”

Aiden slammed his hands on the table and liked to go out and say: "They have failed?"

Could God hear his prayers?

If they really fall in the Pacific, the fleet stationed in Guam will be happy to help with the salvage.

“The way they use the return is different from what we know back...”

The excitement in my heart gradually subsided, and Aiden, who realized that the situation might not be the same as he thought, gradually frowned.

"What do you mean?"

"...only one possibility."

"what exactly is it?"

"Their fuel has the rest..." The throat vomited, and the engineer looked incredulous and said in a difficult tone. "And a lot left."
