Chapter 945 (2/2)

What star ring trade uses as propulsion device is not chemical rocket engine in traditional sense, but electric propulsion rocket engine named r400 designed by Jiang Lin based on r320 rocket engine.

Electric propulsion, that is to use electric energy to accelerate the formation of high-speed jet to generate thrust. In fact, the application of electric propulsion technology in the field of aerospace has appeared at the end of the 20th century, but there has always been a shortage of thrust plate, which has not been popularized on a large scale. It was not until the middle of the 21st century that the electric propulsion technology made a great breakthrough in the eschatological time line.

Among them, the plasma propulsion derived from electric propulsion technology has been used in some engines of ”Zhenghe”. Its technical connotation is also very simple, it is nothing more than that the electrons in the ionosphere Do hall drift under the action of cross vertical electric and magnetic fields, and push the spacecraft forward by the thrust formed by the ejected ions.

However, even though the technology seems very simple, today, even the American ed Astra Rocket Company, which is the farthest away from the rocket engine project, has always stayed in the stage of hyping the concept and drawing investors into the pit.

This kind of engine has a characteristic, that is, it will not form more obvious plume and plume in the rocket tail.

Don't underestimate that. It's crucial. This means that if the naked eye is forbidden, only at a certain angle, or at a close enough distance, can the aircraft with this engine be observed from the universe. If it is on the ground, in most cases, even if people find it, they will only regard it as an ordinary star, without paying too much attention to it.

”Now, it is speculated that it is the ring trade that drags asteroids into the Earth Moon system. Under the hype of those who have the intention, there has been a trend of error in public opinion. It's not a large ore-rich asteroid that is pulled into the Earth Moon system by the star ring trade, but the explosive equivalent of 3 billion tons. ””There is no scientific basis for this speculation.” Kerwin fuhr road.

”Yes, but you can't expect everyone to have studied physics and learn to think rationally.” Jiang Chen teases the way.

”Benu” asteroid capture program has been successful, even if we do not consider the dozens of tons of explosives installed on the asteroid, there is no need to worry about any security risks.

As for why, that's a good explanation. Since beinu can be captured by the gravity of the Earth Moon system, its relative velocity in the reference frame of the earth has already dropped to less than ten kilometers per second. Even if it does collide with the earth, it is impossible to compare it with the previous power.

This is a headache.

After some discussion, Jiang Chen made a decision.

”The asteroid mining program starts immediately, and we have to change the public's misconception that our asteroids are not under our control.”

As long as the public can see that the star ring trade not only has the strength to pull this trouble to the side of the earth, but also has the ability to solve the problem, all negative information will be self defeating. The plan was completed last year, but now it is only a slight adjustment.

After arranging this matter, Jiang Chen did not disturb Kerwin's vacation, but turned to board the helicopter and flew off the private island whistling.

Looking at the sand and mud covered wooden beach house, Kerwin's mouth suddenly twitched. He knew he would have built an apron.

After hesitating for a moment, he finally gave up his impulse to clean up and called the decoration company. The telephone number of this decoration company was left for him by the intermediary when he bought the villa. Its business scope is not only decoration, but also building maintenance, overall cleaning, etc.

Only in this way, his original plan to spend a holiday on the beautiful no man's island had to be ruined.
