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

The reason why the middle-aged man chose target No. 2 was that when Zhou Qingfeng was following his grandfather at the base, he went to the toilet and overheard a researcher from Qingshan Base complaining, saying that the construction of Huaguo Power Investment did not follow their requirements and wasted half a month on repairs. place.

The test site base, which had been built a little, remained abandoned without any idea of ​​what to do, with birds trying to build nests there.

This shows that there is no strict guard around the abandoned test site, and it seems to lead to the inside of Qingshan Base, which is a vulnerable point that can be broken through.

The middle-aged man didn't think he could slip into the base easily through this loophole, but he could see if he could find a signal line or something and intercept the signal and eavesdrop.

The higher-ups wanted to know about the various actions of Qingshan Base and provided a total of one million US dollars in activity funds.

The middle-aged man was full of energy and dragged Niu Aihua, who was struggling to walk, through the mountains and forests. Sure enough, he found nothing unusual along the way.

"Hurry up, we'll be there soon."

"I'm a woman. Please help me carry this bag. I can't carry it anymore. I also need some water. Where did you put it?"

"..."

If the equipment debugging was not complicated and required cooperation, the middle-aged man would not want to take a woman on a mission.

It is very inconvenient to walk in the forest at night. Even with night vision goggles, it is easy to miss the mark. The two people are not traveling very fast. The middle-aged man probably can reach the destination at about one o'clock.

At the same time, in the guard room of Qingshan Base, researchers from the "Brave" project team were explaining something to the guards.

"Oh, just leave a door for it, right?"

"Yes, this week's subject is autonomous terrain mapping and surrounding environment collection and testing. Robot No. 13 will come here in two hours to change the battery. You don't have to worry about it. Just leave the door open for it when it comes."

"Okay, no problem. Why did you call 'robot one and three' instead of thirteen?"

"One is the number one series, three is the third station, not the thirteenth...I'm leaving first. If you have any questions, just call the intercom!"

"Let's go, let's fight for one or three robots to replace us as soon as possible, haha."

"It's too early... to leave."

The researcher looked at the positioning on his mobile phone. At this time, No. 13 had moved to the back of the base.

No. 12 was taken by the military to fly around the country. No. 13 synchronized the learning data of No. 12 every day to enhance each other.

I heard that the Electrical Machinery Department is working hard to develop a new battery, hoping that the No. 1 series can get rid of the problem of short legs.

…

Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.

The GSLV MK3 rocket stands on the launch pad. There is a slender white cylinder on the top, which is the iconic escape tower of the manned rocket.

Nadiradze wore a trench coat that was incompatible with the surrounding Indians and accepted Samarkand's adulation.

The GSLV MK3 rocket is a Gaganyan spacecraft launch vehicle designed by ISRO. The design is extremely strange.

On the surface, this is a bundled rocket with two liquid rocket engines in the central core and a solid rocket booster on each side, but this is not the case.

When it took off, only the two S200 solid boosters on both sides were activated, providing about 1,030 tons of thrust. The two engines on the core stage did not work at all, but ignited when the solid rocket burned out.

Therefore, the first stage of this core is actually a "second stage", powered by two 140-ton thrust conventional fuel (poisonous) liquid rocket engines, and the upper stage is powered by a 20-ton open hydrogen and oxygen machine.

So in fact, the GSLV MK3 is not a "two-and-a-half-stage rocket" as it seems at first glance, but a three-stage rocket.

This strange configuration also results in its very low carrying capacity. The low-Earth orbit carrying capacity is only 10 tons, and its take-off weight is as high as 640 tons, which means that the carrying coefficient is less than 1.6...

It is also the Long March 3B rocket with a LEO capacity of about 11 tons, but its take-off mass is only 430 tons...

It can be seen that Nadji Raze can't bear to look at the GSLV MK3. Such a junk rocket is still the best launch vehicle in India. Only it can launch the Gaganyan spacecraft.

The Jaganyan spacecraft is also strange. It has a two-cabin configuration. The return capsule plus the propulsion module weighs 8.2 tons. The Shenzhou spacecraft also has the same mass, but it has an extra orbital module. It is enough to see that the Jaganyan spacecraft is wasted. How much weight.

But Nadiradze had no intention of losing weight. He only wanted to ensure that no one died as much as possible.

To be honest, he is also very dissatisfied with the GSLV MK3. This kind of design can be used in rockets with terrible designs. It is simply a shame for astronauts.

Out of humanitarianism, Nadiradze helped correct a small error in GSLV MK3, allowing the rocket to fly for the first time two months earlier than expected, and also boarded the first fully unmanned Gaganyan spacecraft.

This already made Sivan Samarkand grateful to Nadiradze. After all, he knew how valuable the experience on manned rockets was, and it would be great to have someone to guide him.

"I suggest you improve the configuration of GSLV MK3. If the core stage and booster work at the same time, slightly modify it to have a transport capacity of at least 17 tons, and even have the potential to transport 20 tons."

Nadiradze still couldn't help but express his views on GSLV MK3 to Xivin, but Xivin Samarkand shook his head with a wry smile:

"We have no way to solve the problem of first-stage tail flame reflow and ablation in the simultaneous ignition structure. If you look at the layout of the two Viking engines, the reason why they are used in tandem is because of this problem.

We decided to leave this part of the H-X rocket to the island countries because they have such experience. "

Nadiradze: "..."

ISRO is not all idiots. Of course they are aware of such inferior design flaws, but what may seem like a trivial trouble to other countries may be an insurmountable obstacle for other countries.

Just when he wanted to comfort him, Xiwen's next words immediately turned his pity into helplessness.

"But GSLV MK3 is enough. Its mission is to launch the Gaganyan spacecraft. We have no need to improve it. We will talk about it when necessary."

Nadiradze shook his head expressionlessly, completely losing any hope for Indian aerospace.

However, the three buddies present obviously did not think so. They were very excited about the first unmanned test flight of the GSLV MK3 and the Gaganyan spacecraft. At this time, they were waving flags and cheering enthusiastically, and they were actively interacting with the Moody Immortal who was present.

Moody also gave a speech before the launch before personally approving the rocket launch.

GSLV MK3, a monster that will make any aerospace practitioner twist and scream when they see it, rises rapidly under the action of two solid boosters, taking the third brother's manned space flight dream forward.

Its last launch was in 2014. Nadiradze looked at the flight data and could only say that the overly conservative and inferior design still brought about relatively reliable stability, and there should be no problems.

However, the Jaganyan spacecraft is a bit worrying. I heard that the solar panels were developed by a domestic company, so I hope there will be no problems.
