October of this year was an important turning point for Huaguo Aerospace.

When the space agency held three consecutive days of closed-door meetings, the entire subsequent development plan was significantly adjusted.

First of all, the space agency confirmed the development of 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 flight for about a year or two, and there is some room for change.

Unfortunately, except for the Long March 6, none of the other rockets are suitable for first-stage recovery.

Because except for the first stage of Chang 6, which is a single YF100 engine, the other three core stages are two YF100 or YF77 engines installed in parallel.

This side-by-side installation makes vertical recovery much more difficult and much 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 type of high-thrust and reusable single-combustion engine at this time, and it can only be changed on the YF100.

The YF100 has a thrust of only 120 tons, so it is impossible to have one top two.

Therefore, the final resolution is: the Long March 6 multiplex type with reusable potential, the CZ-6R will be launched immediately, and the configuration can be directly copied from the Xinyuan-1B.

Also, didn't the Sixth Academy buy the technology of K120? No matter what you do, you must also come out with a reusable model for the CZ-6R to use, and ask for a successful recycling by the end of next year.

The Sixth Academy and the Eighth Academy didn't dare to say no in the face of the pressure from the big guy, so they took it head-on.

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

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

Several research institutes suddenly felt the tremendous pressure, but they also took the orders and left.

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

Because the recovery rocket must first have a rocket engine that can adjust the thrust in a wide range and can be reused, at present, it is pointing to the YF100 as a single seedling, and no engine is all for nothing.

And the matter of the Sixth Academy buying K120 has also been put out, and it is obvious that the superiors mean that if this is not possible, you have to wonder if you are deliberately sabotaging.

Originally, the Sixth Academy was still familiar with K120 technology and tried to improve YF100, but now it has directly established a YF100K project, requiring the index to be equivalent to K120V, and the prototype will be tested within one year.

At the latest, in two years, if the chief engineers of the four rocket projects are not good, they can rely on the debt of 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 ushered in the darkest time of overtime......

……

The wind and rain outside were very noisy, but the culprit Lin Ju was quietly hiding at Ulan Hashan Airport to experience weightless training.

He was annoyed by the harassment of the financial institution, and pushed it to a few people below to pass away, and he had nothing to do to watch the training of the flying trio.

Captain Wang Zhi (captain of the flight team, not by military rank in the future, easy to enter) at the base was very enthusiastic, and he had to take him to experience it together.

Lin Ju, who was itching, also agreed, but regretted it as soon as he got on the plane.

Although he believed in the ability of the ground crew, and also believed in Wang Zhi's confidence in personally leading the flight, he was still silent when he entered the cabin.

Worthy of the 60s designed aircraft, this interior ...... There is no interior.

In order to facilitate training and increase the rate of climb, the aircraft was weightless, and everything in the cabin that had nothing to do with it except for the pressurized equipment was dismantled: even the floor.

The seat is a structure composed of two groups of steel pipes and cloth that hold the bulkhead in place, and is equipped with an X-shaped seat belt, which is theoretically strong.

The empty cabin also looks spacious, but the floor and ceiling can be seen from time to time wiring pipes, especially the faded internal structure, which gives a clear sense of the weight of history.

But at this time, it was too late to regret it, Wang Zhi and another base pilot piloted the passenger plane, and the take-off speed far exceeded that of civil aviation, only to feel that the plane did not have much time to move, and the nose of the plane was raised high, and under the impetus of three Soloviev D30KU turbofan engines, it quickly climbed into the sky.

Lin Ju sat with his back to the cabin, feeling as if the plane had been erected, all pulled by the seat belt.

Zhou Rui and Zhao Xiaowen sat opposite him, and they also clung to the seat belt and didn't let go, for fear of letting go and falling to the tail of the plane.

Only Deng Lei was as interested as anyone else, looking at the scenery outside the window, and even joked easily:

"The angle is definitely less than 30, the climb is not terrible, the most feared is the dive descent, you sit in the cockpit with half of your body exposed, you dive down at supersonic speed, the ground is rapidly magnified in front of your eyes, and the blood flows to your legs ......"

"Ah......hh Brother Deng, don't say it, I feel like my legs are starting to weigh up! ”

"Xiao Zhao is right, is this broken plane comparable to that, you listen to the sound, the sound that should be ringing, and the sound that shouldn't be ringing! The old man is really a lard and came here! ”

Lin Ju also had a numb scalp when he heard it, because the sound insulation facilities were removed, the noise of the high-speed airflow hitting the surface of the plane was chaotic and clear, giving people a feeling that the plane was about to fall apart.

Fortunately, it didn't take long for the radio in the cabin to sound, indicating that the plane was about to start diving, and that the seat belt should not be unfastened without permission after the dive, only the personnel accompanying the base said that they could untie it later.

More than ten seconds later, the Tu 154, which had far exceeded the clouds, lowered the nose of the plane and began to dive, Lin Ju at first felt the acceleration of the plane descending rapidly like a roller coaster, but as the plane continued to accelerate, he soon found that the gravity acting on the body slowly decreased, and the whole person began to become lighter.

He tried to wave his hand, but felt only the pressurized air in the cabin, not gravity.

"Passengers, you can unbuckle your seatbelts now, we have 28 seconds, please stay around the seat and feel free to say anything uncomfortable!"

The four of them and the trainers of the base unbuckled their seat belts one after another, and Lin Ju couldn't wait to use his heels to exert force on the bulkhead, and the whole person slowly floated towards the opposite side.

Pull the roof with your hand again, and the body begins to rotate spontaneously.

When he deliberately retracted his limbs and did not touch the object, his body completely lost its support point, as if drowning, there was a kind of helpless but different ethereal feeling.

But before they could get a closer look, the trainer had already approached the four and fixed them to their seats, as the first dive was almost over.

On this day, herders and tourists in the steppes of the Ulanha Mountains saw a spectacle.

A pure white, age-looking plane rushes down from the clouds one moment, then quickly climbs higher, and dives again a little later.

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

However, Lin Ju on the plane was too addicted, and he experienced weightlessness for more than 10 minutes in total, and the trio who trained together also felt the wonderful feeling of weightlessness.

After landing, Lin Ju, who regained adaptation to gravity, received a call from the company and learned that an investment group that came today had made a financing offer of $1 billion for 30% of the shares, and his heart suddenly felt a pang of colic.

He worked hard to earn less than 50 million US dollars, and these big dogs are enough for him to eat for a lifetime, and so many people like to pull investment, and I want to make money so easily.

Lao Ma's empty fork is because there are many investors, so he has the confidence to blow up rockets all the time...... Right?

Lin Ju stopped suddenly, and Truss's T-shaped logo appeared in his mind.

Who said that aerospace companies should launch rockets to the death, and they can also use derivative technology to make money to raise rocket business.
