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

"ten, nine (Nairn), eight (A)..."

In the curry-flavored English of the third brother, on a wasteland at the ISRO experimental center in Bangalore, a triangular body with an arc-shaped cone and a long "needle" suddenly sprayed orange blazing flames around, dragging White objects shot high into the sky.

This is the ground zero altitude test of the escape tower of the "Gaganyan" spacecraft. It is the first safety guarantee when the spacecraft is launched into the atmosphere.

The structure of the escape tower of the Jaganyan spacecraft is very simple. It just places a few small solid rockets diagonally and puts a streamline fairing on them.

If an accident occurs during the flight of the rocket, the escape tower will immediately force the spacecraft to detach from the rocket and fly out to a safe distance, and then detach and allow the spacecraft to land with a parachute.

This is an important life support part for astronauts, and it is also the “easier” part.

Originally, ISRO wanted to test the escape tower separately. It planned to use a solid booster used in the GSLV rocket and change it into a rocket to launch the escape tower into high altitude for testing.

However, after Nadiradze intervened, he directly canceled it and changed it to "zero-zero (zero altitude and zero speed)" ground test. This not only saves time, but also achieves the purpose of verification.

What's more, Lucia applied her own technology to "Gaganyan" to a limited extent, and the escape tower was basically copied. How could something go wrong?

The reason why ISRO wants to do actual high-altitude flight tests is just to fire a few more rockets to create excitement, which will not help the development progress of the spacecraft.

It has been more than three months since the Gaganyan spacecraft received technical support from Lucia. The progress is already very high and it will soon be able to conduct a test flight of the verification ship.

Lucia itself provided the second-generation manned spacecraft technology, which could be manufactured even at the level of Indian industry in the past few decades. The Jaganyan spacecraft was simply a lack of design experience, so the original design was a mess.

Najnadze's actual tasks are only two: to design and modify "Gaganyan" according to the scope of the technical authorization to meet the level required by the agreement; to sort out the Indian aerospace industry, produce qualified parts and establish a standard assembly program.

What India has received is not high-tech, but a set of manned spacecraft design processes and related experience, which is more valuable than technology.

At least that's how Nadiradze explained it. Otherwise, how could the ancient technology of the second-generation manned spacecraft be sold for hundreds of millions of dollars?

Of course, technology is ancient, and reliability is still guaranteed. For example, in this zero-zero ignition test, there were no problems with the flight path of the escape tower and the working status of the engine. The Science Department and ISRO officials on site cheered and felt that they One step closer to success.

"Nadiradze, we are going to hold the most grand banquet tonight, please be sure to attend!"

"This...this, I still have work to do."

Sivan Samarkand excitedly invited Nadiradze, but the latter had an awkward expression on his face and declined politely.

The reason is naturally not because Nadiradze is still very dedicated despite his age, but because of the local banquet... How should I put it, it would be fine if it was a separate high-level invitation. It is basically a Western-style meal with red wine and steak. There are more people like this. The celebration consisted of everyone sitting on the floor and sharing curry, and Nadirazi didn't want to go.

Fortunately, Samarkand did not feel disappointed. Instead, he admired Lucia’s expert’s rigorous work attitude even more.

"Ah, Dr. Naginaze, you are the friend who sincerely helps us. It is a pity that our island partners did not accept your help. Look at them. I doubt whether their work can be completed as scheduled."

"Hehe, hehe." Nadiradze reluctantly fooled him. The recent accident at the Tanegashima Space Center made the third brother a little confused and felt that he had surpassed the island country. Nadiradze didn't know what to say about this.

Although Lucia also looks down on the island nation's aerospace industry, the island nation is famous for its precision craftsmanship and optical equipment. During the alliance period, Toshiba's machine tools were imported to process nuclear submarine propellers. As for India, Nadiradze was only happy that the smell of cow urine could no longer be smelled in the workshop recently. .

Last time an employee reported to him, it turned out that the guy had just bathed in the Ganges and drank a large bottle of cow urine, which almost made him vomit.

Now, Lucia experts are taking over the project and barely pushing the plan forward. If they leave, they will really worry about the third brother smearing cow urine and dung on the outer surface of the spacecraft.

Eh? This problem seems to really exist. Should we go back and consider the corrosion of ablative materials by cow urine? Don’t ruin my reputation as Lucia!

Nadirazi immediately knew what he was doing at night, quickly fooled Samarkand, and then hurriedly asked someone to prepare samples of cow urine and cow dung.

…

"Xiao Lin, your business jet is better. Lying down is much more comfortable than sitting on it."

The boss moved his waist and praised the comfort of the modified ARJ21.

Xinyuan's ARJ21-modified business jet has significantly reduced the number of seats. The standard passenger capacity is 16 to 30 people, and generally speaking, there will be no more than 10 people at the same time. The space inside the aircraft is quite ample. In addition to a separate rest room, all seats have been upgraded. The sofa and interior decoration have also been upgraded.

The senior officials of the space agency planned to go to the Ninth Academy to do something. It happened that the ARJ21 was in the capital, so a few people experienced a real luxury plane.

Since the dawn of the project, big bosses have been flying back and forth frequently, and the chairs on commercial airliners are not so comfortable.

Lin Ju smiled when he heard this and said, "Well, our planes often fly this route anyway. Why don't you just tell me where you are going in the future? If you have time, you can just pick it up, and you won't miss the kerosene."

The boss quickly waved his hand, and he just happened to sit there this time. Strictly speaking, he shouldn't have sat there. If he sat there a few more times, the reporter would have to talk to him.

However, he still couldn't help complaining: "This ARJ21 is so comfortable, and you still fly at supersonic speeds in a high-education aircraft. It's really irritating that people are more popular than others."

Lin Ju: "It is indeed not as comfortable as the ARJ21, but three hours per trip is not short. It would be good to save a little time. Alas, if the oil price did not rise, we could ride the Tu 144 and the Concorde."

Lin Ju suddenly thought of the supersonic passenger aircraft plans of various countries in the golden age of aviation in the last century. The alliance developed the Tu-144, and the country and Dai Ying jointly developed the "Concorde" supersonic aircraft. The latter also flew many times on the Hong Kong-Jiang route. Unfortunately, in the end, these advanced products were wiped out by rising oil prices.

The boss also thought of a lot of things when he heard these two names. "Concord" actually wanted to stay in China back then.

The maximum cruising speed of the Concorde supersonic passenger aircraft can reach Mach 2.04, and the maximum take-off mass is more than 180 tons, which is more than twice that of the H-6. Even at that time, the whole world knew that operating supersonic aircraft was not environmentally friendly, and Air China hoped to introduce a few of them.

Apart from the advantages of supersonic flight, if you think about it carefully, this is a supersonic aircraft that can carry 140 people and fly 6,500 kilometers at up to twice the speed of sound. If the load is changed and the range is increased, it will be a supersonic aircraft with a range of more than 8,000 kilometers. Sonic bomber.

Even if you can't get the technology, it is an important reference when you need to develop a large supersonic aircraft.

But it can be seen in China, and others can see it more clearly, so Concorde’s introduction project ultimately failed, leaving only an unforgettable past event in the hearts of a small group of people at that time.

But now there is no need to introduce Concorde in China. The National Aeronautics and Space Administration's Tengyun project alone does not know how far it surpasses Tengyun.
