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

October of this year was an important turning point for China's aerospace industry.

After the space agency held closed-door meetings for three consecutive days, major adjustments were made to the entire subsequent development plan.

First, the space agency confirmed that it will develop its own reusable launch vehicle as soon as possible.

In particular, the future Chang 5, Chang 6, Chang 7, and Chang 8 will not make their first flights in about one or two years, so there is a certain amount of room for change.

Unfortunately, except for the Long March 6, the other rockets are not suitable for first-stage recovery.

Because except for the Changliu first stage which has a single YF100 engine, the other three core stages are equipped with two YF100 or YF77 engines in parallel.

This side-by-side installation makes vertical recovery more difficult than operating a single unit.

However, if the layout is changed and only one engine is installed and the thrust is not enough, it will definitely be too late to develop a new high-thrust, reusable single-combustion chamber engine at this time, and it can only be modified on the YF100.

The thrust of the YF100 is only 120 tons, so it is impossible for one to be able to support both.

Therefore, the final decision is: CZ-6R, a reusable version of Long March 6 with reusability potential, will be launched immediately, and the configuration can be copied directly from Xinyuan 1B.

Also, didn’t the Sixth Academy buy K120’s technology? No matter how you do it, you must come up with reused models for use by the CZ-6R, and try to complete a successful recycling before the end of next year.

Faced with the pressure from the boss, the Sixth and Eighth Academies did not dare to say no, so they took it on.

As for other models, the team gave two paths: one is to study how to reuse the already determined configuration, and the other is to overthrow and redesign a reusable rocket with the same positioning.

Choosing one can postpone the first flight by one year, and choosing the second can postpone the first flight by two years.

Several research institutes suddenly felt the tremendous pressure, but they also accepted the order and left.

Of course, the greatest pressure is on the Sixth Academy.

Because the recovery rocket must first have a rocket engine that can adjust thrust in a wide range and can be reused. Currently, the YF100 is a single seedling. Without an engine, it is all useless.

The purchase of K120 by the Sixth Hospital has also been exposed. It is obvious that the superiors mean that if this does not work, they will suspect whether you are deliberately slowing down the work.

Originally, the Sixth Institute was still familiar with K120 technology and trying to improve YF100. Now it has directly initiated the YF100K project, requiring the indicators to be equivalent to K120V, and the prototype to be tested within one year.

In two years at the latest, if things go wrong, the chief engineers of the four rocket projects can put their debts on the Sixth Academy: Look, it’s not my problem, it’s that there is no engine.

As for the migrant workers in the Sixth Hospital, they are facing the darkest time of working overtime...

…

The storm outside is very noisy, but the culprit Lin Ju is quietly hiding in Ulan Hashan Airport, experiencing weightless training.

He was so annoyed by the harassment from the financial institution that he left it to the people below to watch the training of the Feitian trio.

Captain Wang Zhi of the base (captain of the flying brigade, he will not be called by military rank in the future, so it is easy to get in) is very enthusiastic and insists on taking him with him to experience it.

The itchy Lin Ju agreed, but regretted it as soon as he got on the plane.

Although he believed in the ability of the ground crew and Wang Zhi's confidence in taking the flight himself, he remained silent when he entered the cabin.

As expected of an aircraft designed in the 1960s, this interior... has no interior.

In order to facilitate training and increase the climb rate, the weight of the aircraft was reduced, and all irrelevant things in the cabin except the pressurization equipment were removed: even the floor.

The seat is a structure composed of two steel pipes and cloth that fixes the bulkhead. It is equipped with an X-shaped safety belt, which is theoretically very strong.

The empty cabin also looks very spacious, but wiring pipes can be seen from time to time on the floor and ceiling, especially the faded internal structure, which makes people clearly feel the weight of history.

But it was too late to regret at this time. Wang Zhi and another base pilot flew the passenger plane. The take-off speed was much faster than that of civil aviation. It didn’t take long for the plane to start moving. The nose of the plane was raised high. Under the influence of three Soloviev D30KU turbofans, Driven by the engine, it quickly climbed into the sky.

Lin Ju was sitting with his back against the cabin, feeling as if the plane had stood upright and was being pulled along by the seat belt.

Zhou Rui and Zhao Xiaowen sat opposite him, holding on to their seat belts tightly for fear of letting go and falling towards the tail of the plane.

Only Deng Lei looked at the scenery outside the window with interest like a normal person, and even joked easily:

"The angle is definitely less than 30 degrees. Climbing is not scary. The most scary thing is diving and descending. You sit in the cockpit with half of your body exposed and dive downward at supersonic speed. The ground zooms in front of you, and the blood flows to your legs... …”

"Ah ah...Brother Deng, stop talking, I feel like my legs are starting to feel heavy too!"

"Xiao Zhao is right. Is this crappy airplane comparable to that one? Listen to the sound. It makes the sound that should be made and the sounds that shouldn't be made! I'm really blinded by lard and came here!"

Lin Ju's scalp was numb when he heard it. Due to the removal of the sound insulation facilities, the noise of the high-speed airflow hitting the surface of the plane was messy and clear, giving people the feeling that the plane was about to fall apart.

Fortunately, after a while, the announcement in the cabin rang, indicating that the plane was about to start a dive. Do not undo the seat belt after the dive. Only the personnel accompanying the base said it was okay.

Ten seconds later, the Tu-154, which was already far above the clouds, lowered its nose and began to dive. At first, Lin Ju felt the acceleration of the plane's rapid descent like a roller coaster. But as the plane continued to accelerate, he soon discovered that the gravity acting on his body was slow. It slowly subsided and the whole person began to become lighter.

He tried waving his hands, but all he felt was the pressurized air in the cabin, without the feeling of gravity.

"Passengers, you can unbuckle your seat belts now. We have 28 seconds. Please stay around the seat and speak out if you feel any discomfort!"

The four people and the trainers at the base unbuckled their seat belts one after another. Lin Ju couldn't wait to press his heels on the bulkhead, and his whole body slowly floated towards the opposite side.

Then he moved the roof of the cabin with his hand, and his body began to rotate spontaneously.

When he deliberately retracts his limbs and avoids touching objects, his body completely loses its support, as if he is drowning, feeling helpless but uniquely ethereal.

But before they had time to feel it carefully, the trainer had already taken the initiative to approach the four people and fixed them in their seats, because the first dive was almost over.

On this day, herdsmen and tourists on the Ulan Hashan prairie saw a strange scene.

A pure white aircraft that looked like it had a sense of age rushed down from the clouds for a while, then quickly climbed up, and then dived again after a while.

This cycle lasted 26 times, and many people took photos and posted them online.

However, Lin Ju on the plane had enough fun. In total, he experienced weightlessness for more than 10 minutes. The three people training together also felt the wonderful feeling of weightlessness.

Lin Ju, who had readjusted to gravity after landing, received a call from the company and learned that an investment group that came today had made a financing offer of US$1 billion for 30% of the equity. His heart suddenly felt cramped.

He has worked hard to earn less than 50 million U.S. dollars. These big dogs can make enough money for him for a lifetime. I can't believe that so many people like to invest. I think it's so easy to make money.

Lao Ma's empty fork is just because there are so many investors, so he has the confidence to keep blowing up the Rockets... right?

Lin Ju stopped suddenly, and the T-shaped logo of Truss appeared in his mind.

Who said that aerospace companies have to stick to launching rockets, but they can also use derivative technologies to make money and support the rocket business.

Thanks to book friend "All Heavens Supreme Emperor" for his monthly ticket and "Xiaohui is not naughty" for his reward!
