Ultra-Dimensional Technology Era

"What a happy event to talk about?" Chen Yao, the chief engineer, came from the workshop.

"It's just..." Li Guoqing explained what Dong Xiande said just now.

After listening to Li Guoqing's explanation, Chen Yao touched his mirror-like forehead and receding hairline, and secretly sighed that the only remaining black hair might be gone forever.

But after taking a look at Li Guoqing who was already in the Mediterranean, Chen Yao felt a little better.

Dong Xiande quickly asked: "Old Chen, how is the progress of our Changwu-D R&D work?"

Chen Yao, who was worrying about his hairline, glanced at his watch and replied, "The progress is already very fast. In about 5 days, we will be able to conduct the first test drive on the ground."

The Chang [-]-D type is a new version improved on the basis of the Chang [-]-B and Chang [-]-C.

Although there is not much improvement in the payload, the maximum payload in low-Earth orbit is about 37.2 tons, and in synchronous orbit is about 21.8 tons.

But the Long [-]-D has added a very important system, that is, the recyclable launch vehicle that Space Exploration Corporation has been working on for several years.

Last year SpaceX went to experiment with the first reusable launch vehicle.

However, the recyclable system of Changwu-D is more thorough. According to the original plan design, not only the first-level recycling of cores can be realized, but also the second-level recycling of cores can be realized.

And in terms of recovery methods, it is also different from the Falcon rockets of the Space Exploration Company.

The core stage of Chang 100-D is to separate near the Karman line ([-] kilometers above sea level), and then adjust the descent posture, and gradually decelerate through the auxiliary engine during the descent.

When it descends to an altitude of about 30 kilometers, it deploys the auxiliary flight wings, enters the large-scale drone mode, and flies directly back to the launch site or recovery site, or the recovery platform ship at sea.

Similarly, the second-level core is also a similar recovery method, but the second-level core has two more stages of low-earth orbit orbiting and entering the atmosphere.

If the first-level and second-level cores of Chang 90-D are recovered successfully, the launch cost can be reduced by about [-]%.

After all, the fuel for launch vehicles is very cheap (relatively speaking), and with domestic electricity prices being lowered every year, the cost of fuel for a long-five launch is about 120 million.

The real bulk of the cost is actually the first-level core and the second-level core. The engines, electronic control systems, maintenance equipment, fuel storage tanks, etc. inside are all things that are priced like gold.

At present, the launch cost of the Chang 5.8-C is 6000 million Chinese yuan per time, and the launch cost of the Chang [-]-D that is being tested is about [-] million.

If it can be reused 10 times, the cost can be reduced to about 5000 million; if it can be reused 3500 times, the cost can be reduced to about 2000 million; if it can be reused more than [-] times, the cost will be as low as [-] million.

However, the recyclable rocket is not without its shortcomings. Originally, according to the design of Chang 55-D, as a one-time launch vehicle, it can increase the payload of low-Earth orbit to about [-] tons.

However, in order to achieve the recyclability of the first-level and second-level cores, nearly 17.8 tons of payload were sacrificed.

What you gain is what you lose, and this is the price to pay for recoverable launch vehicles.

……

Dong Xiande thought for a while and said: "Old Chen, you arrange the test as soon as possible. I will go to the satellite assembly company and arrange personnel to go to Shanmei."

"It's a matter of duty." Chen Yao nodded.

Dong Xiande, who was about to leave, suddenly stopped, turned around and said, "By the way, there will be two batches of new researchers and engineers coming in March, and the number of them is about 500."

"500 people" Chen Yao was surprised, and Li Guoqing beside him also looked strange.

Add 500 researchers and engineers at one time. Where do so many researchers and engineers come from in China?

When he has free time, he is also a researcher and engineer in the aerospace field. Most of them in China are concentrated in aerospace science and industry.

"Could they be student soldiers?" Li Guoqing asked in a cold sweat.

Dong Xiande spread his hands helplessly: "300 are college graduates, and 200 are transferred from the army."

"My God..." Li Guoqing held his forehead and smiled wryly.

It turned out that the so-called researchers and engineers were a bunch of novices, and Li Guoqing and Chen Yao suddenly felt scalp tingling.

Chapter 2 The third batch

In the Changwu assembly workshop, Li Guoqing and Chen Yao were both worried and happy.

After all, increasing manpower is a good thing, but inexperienced graduates and veterans may only come to do odd jobs.

the other side.

Wuwei City in Hexi Province, and Qilian Mountains at the junction of Qing Province.

In Longling, a branch of Qilian Mountains.

A convoy started from Gulang County and advanced along the township road to the depths of Longling.

There are three queues in the front, middle and back of the convoy, and there are not a few buses in the middle of the convoy.

After half a day's trek, the convoy penetrated into a mountain forest, and then disappeared on the township road.

The convoy and the bus came to the secret base code-named Base No. 013 (the base in the middle of Qilian Mountains).

In this convoy, there are 1800 soldiers (1200 to be retired), and 800 senior undergraduates.

Radio silence has been carried out around the base, and soldiers and students are arranged to be stationed inside the base to implement militarized management.

Colonel Sun Hulie, head of the base, accompanied Fang Ge and Jiang Tiansheng.

"Chief Fang, Researcher Jiang, our base is ready." Sun Hulie solemnly saluted the two and reported the situation.

Fang Ge smiled and said, "Thanks for your hard work."

"It's all for human beings." Sun Hulie replied with his head held high.

As the second batch of new human beings completed the implantation work, the third batch of new human implantation tests followed, and the test scale reached 2600 people.

The second batch of 15 new humans is in very good condition. As the program of Nuwa's kernel is gradually improved, Fang Ge and others feel that they are being reborn.

In the true sense of rebirth, energy is provided through nutrient solution, cells in the body are manipulated with cell chips, and muscles, bones, skin and organs are fine-tuned.

Adjust the human body to the strongest state, even the female Fang Ge can lift about 730 kilograms, while the male Huo Yimin can reach about 945 kilograms.

The maximum human muscle strength is related to many factors, the most direct relationship is the physiological cross-sectional area of ​​the muscle.

For example, the angle of the muscle fiber plume, the way the muscle fiber connects, the length, the shape, the degree of activation of the muscle fiber, etc. are all related.

And these things can be upgraded to the limit of the Blue Star organism through cell manipulation and reorganization, such as drawing on the muscle design of mammals to artificially enhance their own strength.

Although Fang Ge's appearance hasn't changed much now, but there is explosive power hidden inside her body. If she fights with a special soldier with bare hands, Fang Ge can instantly kill him.

The improvement of new humans is comprehensive, such as vision, hearing, smell, feeling, strength, speed, and endurance can all be adjusted and strengthened.

"Then arrange 100 soldiers as the first group of implants." Fang Ge arranged.
