The test of the super heavy launch vehicle 13 failed. After the launch vehicle was launched, it disintegrated and exploded in the air in about 27 seconds.

This several modified super heavy launch vehicle has a total weight of 2,686 tons after filling up fuel, and a low-Earth orbit payload of 172 tons, with a load ratio of nearly 6.5%.

Huang Xiuyuan came to the assembly factory of Wenchang Aerospace City through a stand-alone robot. Academician Wang, chief engineer in charge of the 13th project, as well as a group of researchers, engineers, and designers, were all busy.

After reading the preliminary accident investigation report, Huang Xiuyuan roughly understood the possible cause of the accident.

Academician Wang, who was standing by, said distressedly: "The disadvantages of parallel engines are indeed very difficult to deal with."

"As expected." Huang Xiuyuan was not surprised.

Because from the design idea of ​​Chang13, Huang Xiuyuan knew that this project would definitely not go too smoothly. In order to obtain enough power, the Chang13 launch vehicle connected 6 large rocket engines in parallel and used solid fuel N206.

The disadvantage of parallel engines is that they are prone to interfere with each other, which tests the coordinated control between each engine. Once there is a problem with one of the engines, it is easy to cause overall out of control.

This time, the test launch was because one of the engines output power was about 0.61%, which destroyed the original flight trajectory.

And there are other problems with 13 long, which led to the failure of this launch.

Academician Wang said helplessly: "It is estimated that the problem must be ruled out. The next shot may not be tested until September."

"It doesn't matter, failure is also an experience, it's better than actual operation problems."

Academician Wang also looked distressed: "It's just that time is too tight. If it can be extended by one or two years, we will definitely not have such a serious problem."

The aerospace system does not know about controlled nuclear fusion. While being excited about the rapid launch of a large number of space projects, it is also deeply stressed.

This is also impossible. Controlled nuclear fusion technology is too sensitive, which will lead to the complete disintegration of the fragile strategic balance.

Coupled with the possible early appearance of the small glacier climate, it is very likely to intensify the gap between Greater China and other regions. Combined with these situations, it will increase the possibility that some forces will take risks.

Therefore, it is now the most urgent task to fully promote the aerospace industry and build a lunar city.

The test of the Chang13 launch vehicle failed. Although it gave a shadow to the aerospace science and technology industry, Huang Xiuyuan was not too worried. After all, the maximum payload of the Chang13 launch vehicle is only 172 tons in low-Earth orbit, 105 tons in synchronous orbit, and 70 tons in lunar orbit.

The long 11 carrier rocket that uses the Golden-winged Dapeng instead of the core stage can currently achieve 243 tons of low-Earth orbit, 171 tons of synchronous orbit, and 92 tons of lunar orbit.

This is a very amazing payload. It uses the Golden-winged Phang to launch the very mature Long 11 launch vehicle, which is also the main means to enter outer space.

As for why the Golden-Winged Dapeng continued to develop the Long-term 13 after the establishment of the Golden-Winged Dapeng, it was mainly to cooperate with another project.

The comprehensive performance of 13 years old is obviously not as good as the Golden Winged Dapeng + 11 years old, but this project must continue to be developed.

Because in addition to launching within the atmosphere, Long 13 is also planned to be assembled in outer space in a hierarchical manner, that is, after being assembled on a space station, it will be used as a super heavy spacecraft back and forth to the moon.

According to the planning of Aerospace Science and Technology and Eagle Aerospace, the 13th will be decomposed into 5 parts, launched onto the Tiangong Space Station through the Golden-Winged Dapeng, and then the 5 modules will be assembled.

The low-Earth orbit assembly type is 13 long, and the synchronous orbit payload will be increased to 1,880 tons, while the lunar orbit payload can reach 940 tons.

If it is a means of transportation between low-Earth orbit and lunar orbit, the current problem of the return load of the lunar spacecraft is too small.

At present, if the lunar spacecraft wants to return to the Blue Star, the fuel must be carefully calculated and return to the maximum load of the low-Earth orbit. If the various systems of the spacecraft itself are subtracted, the weight of the low-Earth orbit can be brought back, which is about 1.5 to 3.2 tons.

This is still an unmanned transport spacecraft. If it is a human spacecraft, the additional load will be about 0.6 to 1.7 tons.

If the spacecraft personnel exceed 5 people, the payload will drop further.

Obviously, this does not meet the strategic needs of aerospace development. Moon spacecraft must be able to carry larger payloads and return to the Blue Star's near-Earth orbit.

He has been carrying this important task for 13 years.

Although this launch vehicle has an ordinary comprehensive performance in the atmosphere, if it is used to assemble it in low-Earth orbit, it can top 10 lunar spacecraft with a single spacecraft.

This spacecraft assembled on a low-Earth orbit space station is an important means to quickly build lunar bases and lunar cities.

Huang Xiuyuan also knew that the project time was too tight, but he had no choice.

Now Noah will be very crazy. Since this year, the other party has launched 5 new Saturn V, including 2 explosions and 3 successful ones. A small unmanned base of about 24 tons and 5 lunar satellites have been initially established on the moon.

In addition, Musk's space exploration company, Boeing, Blue Origin and other companies have also begun to rebuild the new space station Noah's Ark space station under the stimulation of NASA's huge funds.

As for the Western Union and Lucia, they used the International Space Station to repair the cracks. As for the moon, they only launched one detection satellite in a few years.

This comprehensive space competition made all the small forces stunned. Not to mention catching up, they didn't even have the courage to try.

Blue Star's international pattern has gradually formed three major camps under the impact of this great wave of sand, namely the Greater China Federation, the American Federation (Noah's Society), and the New Zealand Federation (Western Federation + Lucia).

As for the other little shrimps, they are either puppets of the three major forces, buffer zones, or game zones.

The global hot spots have shifted from the Asia-Pacific region to the Ceylon Ocean region, especially the Persian Gulf and the Red Sea in the northwest of the Ceylon Ocean, and the Red Sea are even more in chaos.

The three major forces intertwined in the region, and several proxy wars broke out one after another.

While looking up at the starry sky, the open and secret struggles on the ground did not stop at all. In order to seize resources, some behaviors became more open and persistent.

Greater China is better, after all, there are various new materials and efficient element refining technologies, which do not require much external resources.

The means of snatching resources in the end are relatively mild and hidden. The more purpose is actually to curb Noah and get more resources.

The Noah Society's methods are much more brutal, directly tearing apart the false face that has always been, and plundering various rare resources in a crazily manner.

Many resources in places were mined in devastating ways by Noah.

Especially in the Atlantic coastal areas, Noah will place all five aircraft carrier fleets in the Atlantic Ocean.

These plundered resources were invested by them in the fields of aerospace and military industry. Under tremendous pressure, the strength of the Noah Society was also expanding wildly.

The whole world was trapped in a kind of madness and depression, and the social atmosphere of the first Cold War era appeared again.

Many smart people have seen the decisive factor of a Cold War in space.
