Chapter 323 (2/2)

Although Wang Bin is very confident in the blades made of glass produced by their company, they do not think that such an impact will break or fall off the internal glass blades.

However, the material of glass is obviously different from steel and titanium alloy. After being impacted by hard objects, it will not deform like metal, but will directly crack or fall off. Therefore, if all blades are not replaced, in case of potential safety hazards, the consequences will be serious.

Although it seems very troublesome to replace all the fan blades. If it was other engines, it would be impossible to complete it every few days or even ten and a half days and months, but Wang Bin didn't need so long to replace the blades of their engine. It only took an afternoon.

Professor Zhang completed the replacement of the fan blades of the engine of the improved No. 9 transport plane, and the next day, the improved No. 9 transport plane returned to the blue sky and began a series of test flights on the plateau.

....................

After changing the blades of the engine, Wang Bin, Professor Cha and others immediately put them back to Tiangong technology. After all, under the current situation of Tiangong technology, they are not allowed to stay outside for a long time.

At the same time, just a few days after Wang Bin's return, Wang Bin finally completed the assembly of their second Tiangong technology rocket, that is, tiangong-2 five ton launch vehicle.

The total weight of the rocket after refueling was as high as 500 tons, and the vertical height reached nearly 35 meters.

However, it can also be seen from here that there is still a lot of room for improvement in the rocket technology of Tiangong technology at this time. After all, under the same total weight of the rocket, if the total weight of the official rocket reaches the level of this rocket, its low earth orbit carrying capacity can reach at least 8-10 tons, but the low earth orbit carrying capacity of this rocket, But only more than five tons, less than six tons.

Of course, after the final assembly is completed, Wang Bin and they are naturally ready to start their first launch.

Moreover, since this rocket is the first rocket of Tiangong technology, Wang Bin handed in their application for launching this rocket as soon as it was produced.

At the same time, after the application was submitted, Wang Bin also called Qin Lao, the person in charge of the Aerospace Department, for his opinions.

However, when old Qin learned the news, he was also very happy. Although he had seen the manufacture of this rocket by Tiangong technology in the rocket factory of Tiangong technology before, and he also saw that this rocket is a design drawing, but Tiangong technology can complete it within the time they planned, Still have a certain skepticism.

Now Tiangong technology has finally completed the manufacture of this rocket. Naturally, he is very happy, but in addition to being happy.

He also suggested to Wang Bin that for the sake of safety, he hoped that the five ton rocket of Tiangong technology could also be launched from the offshore launch platform in the South China Sea.

After all, compared with the launch from the land launch pad, the safety factor of maritime launch is undoubtedly much higher for personnel. Even if the launch fails, it will not cause major casualties except the damage caused by the rocket itself, spacecraft and launch platform.
