Chapter 226 (1/2)

Of course, in addition to the large thrust rocket engine technology of one or two thousand tons, Wang Bin and Tiangong technology also need a small thrust rocket engine technology of one or two hundred tons, or even a small thrust engine technology with a thrust of only a few cattle and dozens of cattle, if they want to develop aerospace technology.

In addition, there are steering propulsion devices and measuring wheels of space vehicles.

These technologies need energy coins to buy. Thinking of these, Wang Bin began to worry about the energy coins in his hands again, because according to the technologies that need to be purchased, it is really not enough to buy just by relying on the energy coins in his hands.

After all, a thousand tons of high thrust rocket engine technology, coupled with technologies in other parts of the rocket, such as rocket body technology and fuel tank technology, will require nearly two million energy coins, while a hundred or two tons of low thrust rocket engine technology will require at least hundreds of thousands of energy coins.

If you add a few cattle, dozens of cattle and various steering thrusters, the energy coins required will definitely exceed the energy coins Wang Bin now has.

In addition, if you want to manufacture launch rockets, these rocket engine technologies alone are not enough. You also need multi-stage rocket technology, bundled rocket technology, etc. according to Wang Bin's estimation, no one has two million energy coins.

He can't buy a complete set of high thrust rocket technology at all. If he adds rocket recovery technology, Wang Bin needs at least 8 million energy coins.

This made Wang Bin a little stunned for a moment. After all, in his original plan, Wang Bin thought that as long as the price of three or four million energy coins, he could buy the whole fourth generation rocket technology. However, after calculation, the price of four million could only buy the engine technology, which made him a little overwhelmed.

But then Wang Bin thought that he didn't need to buy a complete set of fourth generation rocket technology. In fact, many technologies. With the strength of Tiangong technology, as long as there are corresponding talents, it's not difficult to develop technologies that are not different.

Moreover, even if Wang Bin and Tiangong technology can't develop corresponding technologies for a while, he can turn to the official for help, and the strength of Huaxia Aerospace absolutely has relevant technologies.

Thinking of this, Wang Bin loosened his frown, so he now used the price of one million energy coins to buy the fourth generation rocket engine technology of 1000 tons, and then spent the price of 55 energy coins to buy the fourth generation engine technology of 100 tons and 200 tons.

As for the micro rocket propulsion technology with smaller thrust, Wang Bin did not buy it, because he knew that such propulsion technology could definitely be developed with the ability of Tiangong technology. Even if they could not, he could also turn to the official space agency for help.

In terms of various space steering thrusters, Wang Bin did not buy them in the system. As before, thrusters like this are definitely not a problem for their Tiangong technology. He doesn't have to worry at all. Moreover, as long as he has high thrust rocket engine technology, the official is absolutely happy to help.

Finally, the rocket control system, the rocket fuel tank and the recovery system. For the rocket fuel tank technology, Wang Bin thought about it. He still spent 300000 energy coins to buy five diameters, namely 1m, 1.5m, 2.5m, 3.5m and 5m, 15 fuel tank modules and separators, and larger diameter fuel tanks and separators, Wang Bin didn't buy it.
