Chapter 1004 (1/2)

After seeing the gate of the cargo ship, Jiang Chen almost didn't laugh.

Dare you, these old maozi changed the rocket directly. They installed the main engine in the middle of the rocket in quadruple. They canceled the design of the three-stage rocket. They designed the fuel tank at the bottom of the middle section of the spaceship, and the upper part was the cargo bin. Although the overall layout has exceeded the level of the times, but the power system is still the original chemical fuel engine.

The advantage of this rectangular aircraft lies in the vertical acceleration, which can effectively alleviate the load on the aircraft shell during the acceleration phase. But at the same time, the problem is that this kind of spacecraft will be in trouble if they want to make a turn in space. It's like a toothpick. It's hard to break a toothpick when you poke it straight into the wall. But when you hold both ends, you can break it with little effort.

It's OK to make a small turn through the speed difference of the four engines. However, if the steering angle is more than 90 degrees, it's only possible to complete it with the help of planetary gravity. Unless they put a little engine in the middle, but it would be too bulky.

When it comes to the engine, Jiang Chen is still blushing. After all, it is his side who has made a hole in his side. After the space elevator is built, the future of the rm-320 chemical fuel rocket will be basically over. With a high energy storage battery and a palm sized cesium metal block, the cruising radius of a conventional chemical fuel rocket is as high as two small house sized fuel tanks. The limitation of technology lies here, which can not be solved by simply improving technology.

It's like a bronze knife. No matter how hard you refine and forge, you can't compare it with the one made of steel.

”Although it's not impossible to use chemical fuel engines as engines, we can only make do with them, and they will be eliminated in 20 years at most. Rocket propulsion without working fluid is the main direction of future space development. It is very difficult to eat a fat man at a time, but we can start with electric propulsion Don't take notes. I'll just say that Jiang Chen looked at that big nose hair son directly from the pocket to take out the notebook to start to write, the face suddenly some hang not live, hastily said.

He really doesn't understand aerospace. His only role in the space Department of satellite ring trade is to save the files of the last world to the database of this world. All departments are only responsible for the affairs of each department, and no one knows who has researched these documents.

However, he still knows a little about the general direction, so that's what he said casually. As for the ban can not help but ponder, Jiang Chen himself is not sure.

Yuri touched the back of his head with embarrassment. ”I think what you said is quite reasonable. However, there is no working fluid propulsion principle. We have studied it since the Soviet era, but we have not made any achievements until now. We do have a prototype of an electric rocket, but the propulsion power is too low to match the carrying capacity of this chemical rocket. ”

”If all this has been studied by you, it's time for us to come to you and learn from it.” Jiang Chen saw that the Russian had a good temper, so he played a joke with him.

”Learning from scriptures? What is learning from scriptures? ”

However, although Yuri speaks Chinese very fluently, he obviously has not learned this spoken language. After touching his head, he has not yet understood that Jiang Chen is joking with him. Instead, he asks seriously.

”Well, nothing. You can understand it as learning.”

Yuri made a sudden realization of the expression, but immediately shook his head, took out a piece of information from his pocket and handed it to Jiang Chen's hand.

”You don't need to learn from the classics. I just want to ask, what do you think of this aircraft? Can you stop at the port around the city? If you can't, please let us know what's beyond the standard

Jiang Chen took this dense document written in English for a long time, but he didn't see anything. Finally, he gave it back to Yuri.

”I can't give you a reply right now. In fact, you don't have to give me this document. The technicians I brought here are specialized in the task of identification. At that time, the parameters of the aircraft will be imported into the computer, and we will use the simulation program to check whether it can meet the safety standards, and we will know if it can meet the safety standards
