I ask you to build tractors, but you build rockets?

"Why is it so high?"

Robert's first reaction was that it was impossible, but he immediately realized it.

Supersonic flight brings not only high ticket prices, but also great savings in time costs.

In the past, a flight took at least sixteen hours, but a supersonic passenger plane only takes three or four hours. The free time can be used to fly several more times, and the profits that can be obtained by a single aircraft are naturally higher.

From this point of view, the economy of supersonic passenger aircraft is definitely no problem, but the problem is noise.

"What about the sonic boom? How are they going to deal with the public protests?"

Jim couldn't answer this question, but he thought about it and gave a very clever response:

“There are so many supersonic aircraft in China now, and they don’t seem to be troubled by this problem.

However, if it can really promote the relaxation of restrictions on supersonic passenger aircraft, it will also be beneficial to SSTO and SR91.

When they enter service, they will inevitably fly at high intensity. At that time, we will also have to convince the public to accept the noise of these aircraft. "

"Well……"

Jim's words made Robert feel very reasonable. The noise problem of hypersonic flight will be exposed in one or two years at the latest, and it will be noisier than supersonic passenger aircraft.

But the Air Force will never compromise, so looking at it this way, we can use their strength to solve the problem.

"Then, let's also talk about it. If things go well, NACA also supports the supersonic airliner plan."

"Then I'll go get in touch... Oh, one more thing, are our nuclear experts ready? I met a guy from China a few days ago. All of Luo Luo's nuclear experts who are going to go to the moon have arrived in China. I’m afraid that United Mining’s detection operation is about to begin.”

…

Class B base.

When Teng Yun completed the 24-hour flight and landed on the runway of the base again, Academician She immediately saw the Jiuzhang spacecraft that had been pushed to the open space next to the runway. From a distance, it looked like it had landed on the earth. The spaceship is also extremely conspicuous.

He immediately wanted to go over and see what was going on, but now he had just been moved to a chair. Almost every one of the 22 crew members on this mission had an extraordinary status and must take a precious commemorative photo.

After taking the photo, Academician She was pushed over in a wheelchair - it is better for the elderly to be more cautious, as their adaptability is far less powerful than that of professional astronauts.

His wheelchair was stopped before he got a hundred meters closer to the spacecraft, and then he saw Serev, wearing a white one-piece lab coat, walking over and winking:

"How does it feel to be in space? It has to be the most amazing moment of your life."

"Not bad... What did you do to move it out? Are you ready to transport it out? Why didn't I see the truck?"

Academician She looked around for the heavy-duty unmanned truck that previously transported Xinyuan No. 4, but he saw nothing. Even the gate of the base did not look like it was about to transport large items.

"It's going to be shipped out, but not on a truck."

Serev became excited when he said this and made an upward gesture:

"I decided to let it take off here and fly directly to Yizhou for shipment."

"ah?"

The other party's surprise was completely expected by Serev, and he explained:

“Although the Jiuzhan is not as large as the Xinyuan 4, its width and irregular shape make it more troublesome to transport... Mainly because it is slow, and the hoisting also requires a lot of attention.

It can output 120% thrust on the ground. Now its internal empty weight is only 39 tons. We add 60 tons of fuel to it and let it fly directly to Yizhou and enter the mainstream of the Yangtze River without taking the narrow Minjiang River. .

I have calculated that when flying on the ground, it can reach a speed of more than 1,900 kilometers per hour. 60 tons of fuel is enough to fly 150 kilometers safely in 5 minutes. It only needs to add fuel once in Renshou, and it can be installed in Yizhou before evening. Boat. "

"But water transportation from here to Yizhou only takes a day and a half at most."

Serev: "Yes, but this flight can also test the flight computer. It would be a pity not to fly such a spaceship-shaped aircraft in the atmosphere.

Think about it, when people look up, they can see such a huge spaceship flying overhead. Doesn’t it feel like they have traveled to the future? Or saw a UFO? "

Academician She: “The Aviation Development Commission did not agree!”

Serev: "This is an intra-atmospheric flight. The Air Force and the province have agreed. It does not require the approval of the Aviation Development Committee."

"..."

Well, Academician She knows that both the Rongcheng Military Region and the provincial government have a resigned attitude towards Xinyuan, and it is really not difficult to facilitate this flight with their abilities.

However, he was still worried about the safety of flying. Although there was no need to doubt Xinyuan's technical ability, he still felt a little numb when he thought of this big guy who looked incompatible with the old aerospace flying around.

The incident suddenly happened and he couldn't stop it now. Just when he was about to ask a few more questions, he noticed that Serev was wearing a one-piece lab coat from a closed workshop and had boots on his feet. He suddenly felt confused and asked:

"Liao Fu, why are you wearing such tight clothes on such a hot day?"

Serev was stunned, but instead of answering the question, he motioned to others to take Academician She away to a safe area 500 meters away.

Academician She then came to his senses and looked at the Jiuzhang spacecraft not far away. The upper and lower hatches of the personnel on the front of the aircraft were open!

He called out Serev's name but the latter just ran towards the spacecraft quickly, it was already obvious what was going to happen.

The staff next to him tried their best to hold him down to prevent him from struggling to get up from the wheelchair. After finding that his body could not use any strength, Academician She had to shout to the accompanying personnel of the Aviation Development Commission next to him:

"Quickly call Lin Ju and drag Serev down for me."

Several of the entourage were stunned and hurriedly ran towards the base office area. Looking at their backs, Academician She kept complaining that Lin Ju was unreliable. He didn't even show up to stop such an important matter... Wait!

Serev has gone up, so he must not be the only one. He seems to have never seen a familiar executive again!

However, it was too late to do anything at this time. The area around the Nine Chapters had been completely cleared, and the harsh whine of the turbine pump could be heard.

Lin Ju sat in front of the center console in the center of the cockpit in the upper front part of the spacecraft. The large seat covered his whole body.

The interior of the spacecraft is gray with black interior, and according to his request, the displays and lights have a light blue theme. Sitting inside is no different from that in a science fiction movie.

Unlike the space shuttle, the Jiuzhang really gives people the feeling of a spaceship, and just sitting in it gives a breathtaking sense of satisfaction.

There are two seats on his left and right sides. Ye Changsi, Serev and other senior engineers of the base are all there. They are not worried about the team being wiped out - anyway, as long as the boss dies, the base will lose its meaning of existence.

Serev's current role is that of the co-pilot, but in fact, none of the five people have anything to do. The entire flight process is taken over by the enhanced version of SC09. The aerodynamic shape of the Nine Chapters is the same as that of the XN90, but it is smaller, making it easy to control.

The four engines at the bottom and the two engines at the tail were ignited one after another. The five people in the cabin first felt the vibration of the entire space, and then suddenly felt a sense of being out of bounds. The base factory building seen through the porthole completely disappeared within a few seconds. , only the sky remains.

SC09 accurately controls the thrust and fine-tuning nozzles of the four engines at the bottom, hovering the spacecraft at a height of more than ten meters, then turns in the correct direction, then tilts the attitude and starts the two engines at the tail at full power.

Academician She on the ground first felt the strong airflow coming towards his face, and then saw the Jiuzhang No. 1 ejecting almost transparent light blue flames and slowly rising into the air amid the tremors of the earth and mountains. It started almost as soon as it hovered. The two engines at the rear sprinted straight towards the clouds diagonally above.

In an instant, all that was left in the field of vision were two bright light groups behind its gray-black appearance.
