On the Yinglong, Zhao Hongtao and Zhao Ya have not yet recovered from the shock of reaching space for the first time.

This time it's not a simulation, this time it's real space.

They also went to the bottom of the International Space Station to hang around according to Gu Song's request.

Of course, don't forget to take a closer look at the grandeur of the flint space city.

Even with Yang Haisheng's steadiness, he couldn't help but exclaim: "I can't believe it, it's been built to this extent." ”

In this test flight, Yang Haisheng served as the commander and Jing Zhigang served as the pilot.

Zhao Hongtao and Zhao Ya are auxiliary drivers sitting in the back seat.

In fact, it is also an internship, and the experience increases.

But this is a test flight after all.

It should be said that the two, like Yang Haisheng and Jing Zhigang, also gambled their lives.

Now, the Yinglong is starting to return.

This is the final test. Being able to fly and land back smoothly is a successful and complete test flight.

Yang Haisheng looked at the augmented reality information presented in the field of vision in the real astronaut helmet, noticed the heartbeat of Zhao Hongtao and Zhao Ya, and thought to himself that the training they had experienced was still less after all.

So he said, "Don't worry, the current situation is very good. ”

The driving experience of the Yinglong is really unbelievable.

There is no space shuttle in Huaguo, and Yang Haisheng is in Shenzhou, with a small space, violent shaking, and high-load acceleration...... These have been experienced.

In the Yinglong, the wide cockpit is an independent life-sustaining system. In the event of a change of circumstances, there is even the ability to eject the entire cabin, independently propulsion, and return home.

The avionics system of the Yinglong fully reflects the computing technology level of Flint Technology. Yang Haisheng feels that I am afraid that the next step will be for Flint Aerospace to export a large amount of technology to the two major aerospace groups in these fields.

Like now, in fact, there is really not much room for him to operate manually.

Yinglong has its own specially customized low-power quantum computing system and traditional computing system, and the design, correction and optimization of the return program make Yang Haisheng feel that he can't come up with a better solution.

The aerodynamic ability and engine ability of the aircraft have also been fully felt in the simulation training.

Therefore, he comforted Zhao Hongtao and Zhao Ya easily.

……

On Flint Island, in addition to the team led by Dong Heguang in the command hall, Jian Yushu, Fan Yuanbai, Director Xiong, Deputy Director Tian, and other astronauts are here.

On the big screen, there are real-time images of each of them, and the monitoring images of the aerospace aircraft from all angles are also transmitted.

Hearing Yang Haisheng's voice, Director Xiong couldn't help but smile.

Wang Yang and Liu Yaping were very envious of Zhao Ya.

Deputy Director Tian also said with a smile: "I went to the International Space Station just now, and I think it scared them a lot. Now, I'm afraid that all parties are paying close attention to the return of the Ying Long. ”

Director Xiong echoed: "But Mr. Gu's arrangement is quite exciting. ”

Jian Yushu smiled and said nothing.

Originally, they only planned to take a closer look at Flint Space City, but halfway through Gu Song called and said that seeing NASA making such a fuss in the past two days made them calm down.

So seeing that the fuel was sufficient, Yang Haisheng adjusted his orbit and went to chase the International Space Station.

In every space mission in the past, how could there be such a temporary idea?

That is, the flexibility of the aerospace aircraft and the strong ability of the Yinglong made this scene appear.

Now, the Ying Long has re-entered the atmosphere.

The fact that Yinglong can fly on its own means that it can land more smoothly than the space shuttle.

The reason why the space shuttle takes off by rocket launch is that it comes back from a speed of nearly 30,000 kilometers per hour, and the speed is too fast after entering the atmosphere, and the high heat and high speed when decelerating make the space shuttle structure and materials very stressful.

Therefore, the wings of the space shuttle can only be made so small to reduce the risk in this regard. In order to facilitate thermal protection, the airfoil of the space shuttle is designed to be so thick and the aspect ratio is very small.

But in this configuration, the lift-to-drag ratio is very low, and the aerodynamic characteristics at low speed are so poor that you can't take off on your own.

And the engine of the Ying Long is too strong.

The fact that the payload ratio can be so exaggerated is a good indication of its abundance in terms of fuel. Therefore, when returning, it is enough to use the engine and the vector nozzle to adjust the speed and the angle of re-entry to reduce the speed to the appropriate level.

Beyond that, how can it be simple?

Gu Song repeatedly highlighted his emphasis on materials, and even his doctoral dissertation was in the direction of materials. It is also a high-temperature superconducting and a nano-carbon material, and Yinglong's structural strength and thermal protection ability are really easy for others to understand.

Observing the speed and orbital angle of Yinglong at this altitude, NASA technicians all forgot about each other and exchanged their inner waves.

By the time it enters the Kármán line, its speed is alarmingly low.

At this speed, even if its aerodynamic configuration puts a lot of pressure on thermal protection, it will not be exaggerated by the space shuttle.

In the Oval Office, except for a limited number of scientific advisors, no one else could read it.

The Grand Commander asked, "Their return data...... Is it normal?"

In front of this group of people at the core, what is the need to lie?

"It's not normal...... But...... Excellent......"

How can a company that can develop a 100-ton super-heavy rocket not be able to handle the structural strength and thermal protection of a spacecraft under such data pressure?

In ESA, looking at the high-level performance on the return trip, he muttered: "Houston, we are in trouble......"

While sitting next to him, he didn't feel funny about such a joke, but sighed: "This time, the trouble is really not small." Aerospace planes...... With it, who can say that the plan for the Flintstone Space City is just a pipe dream. What's the point of Ouranos with that?"

Judging by the distance between the two at the time of shooting, the spaceplane is 55 meters long and has a wingspan of 25 meters. This size is larger than the largest space shuttle orbiter!"

The colleague nodded in acknowledgement, admiring and enviously saying: "Judging from its aerodynamic layout and the take-off phase data shared by NASA, its engine is a monster." So perhaps, its payload and cargo compartment are twice or more than the size of the space shuttle. ”

"No wonder Flint Aerospace has never had a plan for the development of a manned spacecraft, and it was said from the beginning that it was an aerospace aircraft. It seems that we have all guessed wrong, I am afraid that the first residents of Flint Space City will not pass through Shenzhou at all, but directly through the aerospace plane. Judging by its full acceleration...... The threshold is further lowered ......"

A few people said a word, and finally laughed at themselves: "Houston, we're in trouble......"

……

On Flint Island, above the end of the runway, the Ying Long finally appeared.

Not caring about the excitement of these people in the command hall, Ying Long calmly raised the nose of the plane and landed gracefully on the runway.

Judging from its approach angle of attack, it can be seen that it has indeed departed from the perception that the space shuttle is actually a space glider.

It didn't "fall" off near free land, it really flew back.

The big guy, which is more than 400 tons, began to slow down, and the parachute to assist in the landing has been opened.

A big show that was only noticed by the top institutions and high-level leaders of the space powers came to an end.

But since Gu Song asked Ying Long to go around under the International Space Station, it naturally wouldn't end in such a low-key manner.

On Weibo, Gu Song posted a Weibo.

With four pictures.

One is taken from the International Space Station (ISS) with the Space Shuttle Endeavour being connected.

One is the Yinglong taken from the International Space Station, and the words "simulated picture" are written on the picture with a rough PS effect.

One is the driving picture of Yang Haisheng and Jing Zhigang.

One is a close-up of the landing on Flint Island, with the exterior details of the Ying Long at a glance.

[@顾松: I would like to introduce to you the aerospace plane that I have just successfully tested: Yinglong! Single-stage orbit, quick round trip, and by the way to the International Space Station for a friendly visit. @NASA，Suprise！】

[@flyme100: Lying in a big groove!!]

[@大唐枫林: Space Shuttle Representation...... I'm just a younger brother...... Congratulations!]

[@行者旅归来: This timing is so coincidental...... Or can I already slap my face at any time?]

[@神秘世界观: Lying ...... Isn't it spicy Yang Haisheng and Jing Zhigang? So what is the nature of this test flight? What about the details? What about the press conference?

……

Naturally, things fryed immediately without surprise.

The Grand Commander looked at Gu Song's picture, and his face was extremely dark.

It's a simulation? It's the same picture that Howard took to the Oval Office!

That's how this guy went?

It also mocks in this way, implies and threatens unscrupulously.

Isn't my Aramco's nuclear-powered ship fierce enough and not enough mushrooms?
