Chapter 284 (2/2)

Because the greatest difficulty in the design and manufacture of a rocket engine is the design and manufacture of the turbopump inside the engine, in addition to the problems in materials.

However, the hydrogen density of hydrogen oxygen rocket engine is very low, which leads to the difficulty and cost of designing and manufacturing turbopump.

However, although it is less difficult to develop methane rocket engines and rockets, in terms of specific impulse, the combustion efficiency of liquid methane engines is not as high as that of hydrogen and oxygen rocket engines, so Wang Bin's Tiangong technology will pay more attention to the research and development of hydrogen and oxygen rocket engines.

With Wang Bin's introduction, Qin and others have a better understanding of Tiangong technology and rocket engine technology, and have more confidence in the rockets launching Tiangong technology during the air show.

Mr. Qin said: ”Mr. Wang, after visiting your rocket engine laboratory of Tiangong technology, I look forward to your rockets of Tiangong technology. I look forward to your rockets flying into the sky and successfully sending the launch target into space.

After listening to what Qin said, Wang Bin also looked happy.

Then, he said to Qin Lao and others again: ”Qin Lao! Although Tiangong technology has made some achievements in the research and development of rocket engines, this is far from enough. After all, the rocket engine with the maximum thrust of Tiangong technology is only less than 500 tons.

Therefore, we must work harder to develop engines with stronger thrust, higher specific impulse and stronger carrying capacity as soon as possible. ”

”Good! Good! Good! With an enterprise like Tiangong technology, why don't you worry that our country's aerospace industry can't develop!” after listening to what Wang Bin said, old Qin said happily.

”To tell you the truth, Mr. Wang! If I had known that you Tiangong technology had such advanced aerospace technology, I would have forcibly ordered you Tiangong technology to enter Aerospace Engineering and develop relevant technologies as soon as possible.

In this case, maybe you Tiangong technology have already successfully developed the rocket and launched it. Where can we use it until now? ”Old Qin thought and said.

”Mr. Qin, your expectations for our Tiangong technology are too high. According to the situation of our Tiangong technology, even if you give us Tiangong technology a task earlier, I don't think it can go there quickly. After all, our Tiangong technology has too few research and development talents in this field. Taking the laboratory here as an example, it's easy to add up all the personnel But it's less than 1000 people, even if you add the personnel at the launch site, it's less than 5000. The most important thing is that most of these personnel just came out of school this year, which is not worth mentioning for the huge aerospace project. ”Wang Bin smiled after listening to Qin's words.

Yama airlines, a well-known airline in a country in the Pacific, although it can not be compared with the world's most famous airlines, such as the two giants in the aviation industry in the western continent and the new continent.

However, there is no doubt that in addition to the two Big Macs, Yama airlines can definitely be said to be the world's top airline.

At this time, in an office in the headquarters building of the airline, as one of the executives of the airline, Jennings is seriously stopping the report of an employee of their company and raising his own questions from time to time.
