Chapter 401 (1/2)

After all, a civilized spacecraft wants to fly in the universe for a long time, especially when it has just stepped out of its civilization's parent star and has not mastered artificial gravity technology and artificial anti gravity technology.

The vast majority of the people of their race should at least have the physical quality to meet the ability to survive for a long time under the weightless condition of the universe.

In today's human civilization, before Wang Bin and Tiangong technology developed genetic agents, most people could not survive in a weightless environment without professional training.

Even the specially trained astronauts, in fact, each time they carry out space activities, the load on their body is very huge, and even irreversible long-term damage will occur.

Not to mention, the time required for space navigation is very long.

Not to mention sailing outside the solar system. Just in the solar system, with the current scientific and technological level of the earth, it will take several months to go to Mars and Venus. This is only the planet closest to the earth. If you go to a more distant planet, it will take longer, a few years or even decades.

.......

In the following few days, Professor Zhang's physical condition was getting better and better day by day, and his spirit was getting better and better day by day. Only in less than a week, Professor Zhang had changed from a dying old man with oil and light to a healthy man with red face and full of energy.

Moreover, Professor Zhang's physical condition is even better than that of ordinary middle-aged people in their 40s.

Therefore, on the fifth day, Professor Zhang was discharged from the hospital, but even so, in order to ensure his physical condition, Professor Zhang still had to be examined by Professor Li every day.

With the improvement of Professor Zhang's physical condition, Wang Bin finally let go and paid attention to the progress of other projects of Tiangong technology.

At the same time, since the air force base where Qiu Shi and Wang Bin are now stationed is very close to Tiangong technology, just across an airstrip, Qiu Shi has basically run to Tiangong technology every day to learn about Professor Zhang.

......

Wang Bin was not very worried about the lunar exploration satellite launched before. With the entry of the lunar exploration satellite into orbit, all kinds of equipment work normally. It is absolutely impossible to have any problems in a short time.

Therefore, in this regard, their Tiangong technology only needs to launch more lunar satellites and make them completely networked.

In addition, in Tiangong technology and other aerospace projects, it is also carried out in an orderly manner step by step.

In addition to aerospace, in the near future, their Tiangong technology will also have a new action, that is, the phoenix-a1 transport aircraft equipped with pulse engine has been designed and ready to start production.

However, this aircraft is not the air space integrated pulse detonation engine they discussed before, but an aircraft using a pure pulse detonation engine.

In other words, this aircraft is the same as the previous phoenix-1. This phoenix-a1 aircraft is only an aircraft in the atmosphere.

However, the performance of this aircraft will be better than that of the phoenix-1, especially in terms of flight altitude and speed.

According to the calculation of Tiangong technology, the maximum flight speed of phoenix-a1 aircraft using pulse detonation engine can reach at least Mach 4, and the flight altitude will also reach more than 36000 meters.
